Woodward was an eminent geologist who accompanied Dawson to Piltdown town in order to visit the site where the fossil skull was found. They dug the site where the skull was found and found the remains of prehistoric animals, stone age tools and an ape-like jaw bone with human-like teeth that seemed to link to the skull that was initially found at the site. 11. The significance of the canine tooth that was found was to eliminate all forms of doubt that came with the reconstruction of the ancient skull by Woodward. If the canine matched its size in accordance with the jaw that was found, Smith would be able to endorse his predictions. 12. The second Piltdown man was found just two miles from where the first Piltdown man was found and was discovered by Dawson. The second find was very significant as it acted as proof of the first finding and also helped enforce how genuine the first find was. 13. Kenneth Oakley was a scientist working at London’s Natural History Museum. Kenneth was the man who applied chemical tests on the fossils so as to help authenticate and date the fossils and whose test rendered the fossils as fake as they were much younger than was expected. 14. The jaw and the canine tooth were believed to have been forged. The jaw was believed to have maybe been an orangutan’s and the teeth had simply been filed flat so as to disguise them, and the canine tooth appeared to have been crudely filed in a hurry and colored with paint. 15. Sir Arthur Conan Doyle passed by the digging site where the fossils were discovered while on his golfing rounds, and the possibility of him planting some of the fossils that were found acted as evidence of his involvement in

The Personalisation Agenda - Dissertation Example In the same year, a concordat was issued between central government, local government and the social care sector. The document is entitled â€Å"Putting People First: A Shared Vision and Commitment to the Transformation of Adult Social Care (2007)† and through it the idea of a personalised adult social care system was first introduced. The plan called for affording people maximum choice and control over the health care and services they receive. The plan dovetails a more broad-based government strategy that included the notion of â€Å"place-shaping† and other concepts contained in the local government white paper â€Å"Strong and Prosperous Communities† (2006). In the 2008 Carers’ Strategy, the New Deal has advanced the initiatives of integrated and personalised services. Carers called for recognition of their work and expertise, better service coordination and information, improved collaboration between staff and agencies, and health and social care. The Carers’ Strategy was arrived at after a wide consultation and with the cooperation and agreement of various government departments. Many of the themes articulated in recent developments in the personalisation agenda are not new, having been contained in the community care reforms under the National Health Service and Community Care Act of 1990. These reforms aimed to develop a needs-led approach wherein new arrangements for assessment and health care management would include individuals receiving tailored packages of care rather than block-contracted services. The practical advantage in the development of individual or personal budgets is the direct payments scheme, initially made available to disabled adults of working age, but since then has been extended to other groups. The success of the scheme covered some 54,000 individuals as of March 2007, including parents who cared for disabled children and young carers, who used direct payments. The use of direct payments actuall y came about as an initiative championed by disabled people. Among the driving forces behind direct payments were the service user movement, the mental health survivor movement, and the social model of disability, which originally took root in the 1970s when people first lobbied for change. Throughout the development of personalisation, key concepts included independent living, participation, control, choice and empowerment. 2.2 The Social Model of Disability The social model of disability was developed in the 1970s by progressive members of the Union of the Physically Impaired Against Segregation (UPIAS), and given academic validity by the works of Finkelstein (1981), Barnes (1991) and Oliver (1996) (cited in Shakespeare & Watson, 2002). The model is now described as the â€Å"ideological litmus test of disability politics in Britain† (Shakespeare & Watson, 2002). It is relied upon when distinguishing among organisations, policies, legislations and concepts regarding the pro gressive view of disability. The core definition of the British social model was first articulated in the UPIAS document â€Å"Fundamental Principles of Disability.† An edited version that was reprinted in Oliver (1996) and Shakespeare and Watson (2002) is reproduced here, for purposes of elucidation, as follows: â€Å"†¦In our view, it is society which disables physically impaired people. Disability is something imposed on top of our

Juvenile Probation and Community-based Corrections Essay Example for Free

Juvenile Probation and Community-based Corrections Essay This society is much more different than that of yesterday. Today, the country is encountering the biggest economic crisis, the war against Iraq seems to be endless, and the crime rates are increasing to a highly alarming level. As depressing as this current situation appears, the even more devastating part is that the juveniles have been partly responsible for the crime and violence all over the country. Juvenile delinquents are young people. To be more specific, they are individuals below the legal age or under eighteen who have been convicted of a crime. In some states, the legal age for criminal liability has been lowered down to 14 years old (Hill Hill, 2005). Criminal Justice System is a very complicated and diverse field, and the aspect concerning juvenile delinquency has always been on top of controversies and heated debates. These young people are in the early stages of their lives and as such, it is difficult to devise and implement the exact measure that will be necessary and effective for them to learn their lesson. Everybody knows that breaking the law and committing serious crime and violence are unthinkable; however, a more unbearable and heartbreaking thought would be finding out that the law offenders and crime doers are children who, at their very young age, are supposed to be blissfully unaware of the devastating aspect of being a grown-up. They should be in school studying, playing and enjoying their innocence (McCurley Snyder, 2004). Examining all the different angles of juvenile delinquency can be a very complex process, and as such, different measures and approaches are necessary. The observation made by many was that the plans and programs enacted focus too much in the offense, and they may have lost their perspective on the treatment. Some states lowered the age of accountability from juveniles to adults. The courts, on the other hand, created minimum sentences depending on the offense. The problem created in these situations lie in the application. These are offense-based strategies. They create an assumption that the youth who committed a crime should be dealt with no matter what. These laws completely disregard the age, level of maturity, individual differences, and the competence of the person in making judgments. For instance, in Virginia, New York, and other states, laws relating to juveniles have been adjusted to include young children who committed serious crimes to be tried as adults and not as juveniles (University of Pittsburgh, n. d. ). When asked about this new reform, these states simply stated that there are times when the child committed crimes in ways that are heinous and unthinkable, and as such, the acts cannot be perceived as the works of a child. Therefore, the court deemed it proper that they be tried and punished as adults (MoneyInstructor. com, 2009). Rehabilitation and not punishment should be the main aim of juvenile delinquency laws. The presumption is that adolescents are very fragile during their growing years. Thus, they should be treated with extreme care and sensitivity. In order to make an effective prevention plan, one must first understand the person’s main reason in being involved in these criminal activities in order for different methods and approaches in disciplining them to be enforced. The government has not given up hope in reaching out to these youngsters, so they made available community and residential treatments as well as non-residential and institutionalized treatments. A person will be placed by the court on probation when it becomes convinced that the child poses no harm or danger to himself and to the society. Probation is a supervised program commanded by the court of competent jurisdiction in instances wherein the offender is a youth which has been convicted of a criminal act. In this case, the person’s freedom is limited, and his or her activities are restricted and are under the custody of the Department of Juvenile Justice. It is mandated by the court that the youth should follow all the conditions and sanctions in connection with the offense (Florida Department of Juvenile Justice, 2005). Some of the conditions under which a youth is released for probation are being home on a specific time of the day upon the request of the probation officer, attending school, and obeying its rules and regulations constantly. The court may also order the youth to avoid going to a particular type of place and to avoid mingling with a group of people. As of 1999, statistics show that four out of ten juvenile delinquency cases or approximately more than one half were placed under probation (Elrod Ryder, 2005). Community-based correction and treatment pertains to the different kinds of overseeing, control, and support for the youth offenders. These plans and programs were organized because the government firmly believes that one of the efficient and effective ways to influence the young people to change their bad attitudes and behaviors and become a better person is to assist and give them responsibilities that belong to a normal person within a particular community (Elrod Ryder, 2005). It is important for the juvenile to be affiliated with a group. This will give him or her a chance to socialize and be acquainted with other people with whom he or she can relate to. This environment is especially set up and programmed for the children to feel as normal as possible and for them to be engaged in community-related activities. Making these youngsters feel that they are significant and accepted in the society will help speed up their rehabilitation. The government strongly supports the community treatment for juveniles because of the symbiotic relationship created. In this atmosphere, everybody has a role to play; therefore, no one would feel less important and insignificant (Streib Sametz, 2006). Restitution has also been made a part of the community treatment. In restitution, the offender gives either monetary payment or community service in proportion to the damages that the victim suffered. This is a way of reimbursing the victim for everything that he or she experienced because of the crime. The rationale behind this type of treatment is that rehabilitation in the lightest and mildest form may lead the offender to think about what he did. Putting a child in a penal establishment even for just a minor infraction would not rehabilitate him or her; it would ruin the child’s life and his or her perspective for the worst, thereby destroying his or her life (Streib Sametz, 2006). Community-based programs for correction and rehabilitation aim to achieve several objectives. These include but are not limited to sanctioning the youth offenders, assisting them in identifying themselves in relation to the community that they belong to, and helping them realize that being in this program is much better than being placed inside a penal establishment. There are times when they should realize the truth of their current situation because some of these young offenders resist being helped and would rather be put in an institution. Helping them see the possibilities and changes that may occur by reason of their cooperation in the community will help them gain a variety of new perspectives, and in some instances, this is an effective strategy (Elrod Ryder, 2005). Every treatment given is on a case-to-case basis depending on the situation. Thus, there is no treatment proven to be most effective for all juveniles. The community-based treatment generates different results. The test to measure whether or not a program worked is the recidivism rate. If the offender, after finishing the rehabilitation plan, never committed another crime again, that is only the time when the program can be declared as effective (Streib Sametz, 2006). There are also several pieces of evidence that prove that this program is less inexpensive than institutional-based programs. Other programs for youth offenders have been evaluated, and according to the findings, they do not produce great improvement as shown by subsequent acts of the offenders. The government was not surprised to a certain extent because the disparity between the community-based approach and other types of programs can be readily ascertained. Due to these results, some states are making a huge effort to shift their plan of action to community-based systems (Streib Sametz, 2006). There are many factors that come into play regarding the causes and effects of juvenile delinquency. The parents, the church, and the community greatly influence the upbringing of these children. In most cases, the root of the problem for these youth is lack of self-acceptance, guidance, and attention. The future of the country lies in the hands of these children, and if they mess up their present, they will have no future ahead of them. The juvenile justice system is continuing and struggling to attain its purpose in giving the youth a second chance at life because of that promising hope of a brighter tomorrow for the entire country.

Advantages And Disadvantages Of Encryption Security Types Computer Science Essay

Advantages And Disadvantages Of Encryption Security Types Computer Science Essay An Egyption scribe used non-standard hieroglyphs in an inscription about 1900 BC. Example of written cryptography is the first documented that lists by Kahn. A piece of flat stone carved into a collage of images and some writing to identify themselves in trading dealings in 1500 BC antique Assyrian merchants used in intaglio. The digital signature produced by this mechanism. This signature belongs to the trader, but they only have that intaglio to produce the signature. The reversed-alphabet simple replacement cipher known as ATBASH is used by Hebrew scribes writing down the book of Jeremiah in 500-600 BC. A small number of Hebrew ciphers of the time are only one that is ATBASH. Skytale a device used called by Greek which is a staff around that a long, thin strip of leather was wrapped and written on. The leather was taken off and worn as a belt. It would seem that a matching staff and the encrypting staff would be left home by the recipient. In the field of 100-44 BC in government communications used a simple substitution with the normal alphabet by Julius Caesar. This produce only in a little amount, but it is not stronger like ATBASH.When this read by few people it was good enough. Julius Caesar didnt trust the messengers but trusted his associates. Inspired the solution of a cryptogram in Greek for the Byzantine emperor by A.D Abu Abd al-Rahman al-Khalil ibn Ahmad ibn Amar ibn Tammam al Farahidi al-Zadi al Yahmadi wrote a book on cryptography in 725-790. Plaintext at the massages start was based on the result. It was a regular cryptanalytic technique and used still in WW-II in opposition to Enigma messages. Kahn has found the first model of the nomenclature. A grouping replacement alphabet and small code compiled by Clement VII at the appeal in 1379 Gabrieli di Lavinde. For the next 450 years this class of code was to stay in common use in the middle of diplomats and some civilians. There were stronger ciphers being imaginary in the interim in the face of the truth, probably because of its relative expediency. The manipulative a cipher disk to make things easier the process, its make-believe and available the first polyalphabetic cipher at 1466 Leon Battista Alberti. Until the 1800s, this type of cipher was actually not working. In addition his own creation, Alberti wrote expansively on the position the art in ciphers. He also used the disk for enciphered code. These systems were much stronger than the nomenclature. The first book wrote on cryptology at 1518 Johannes Trithemius. Each letter was represented as a word taken from a succession of columns that make-believe a steganographic cipher. The now-standard form of rectangular substitution tables is described as polyalphabetic ciphers. The notion of varying alphabets with each other introduced by Johannes Trithemius. The key for a repetitive polyalphabetic cipher is introduced at 1553 Giovan Batista Belaso the opinion of using a passphrase. Introducing the digraphic cipher wrote a text on ciphers at 1563 Giovanni Battista Porta. Transposition, substitution and symbol substitution are classified as ciphers. To confuse the cryptanalyst he uses the optional of synonyms and misspellings. The first authentic plaintext and cipher text auto key systems together with wrote a book on ciphers at 1585 Blaise de Vigenere. A biliteral cipher known today as 5-bit double encoding at 1623 Sir Francis Bacon described a cipher which now bears his name. Dr.Robert Patterson make-believe his wheel cipher perhaps aided at 1790 Thomas Jefferson. The father of US cryptanalysis was in a job as a civilian cryptanalyst at Riverbank Laboratories and performed cryptanalysis for the US Government is be honored at 1917 William Frederick Friedman. The Enigma machine was taken over and superior upon to become the cryptographic workhorse of Nazi Germany at 1933-1945. But the Enigma machine was not profitable success. U.S. Data Encryption Standard preferred with changes by the US NSA based on the Lucifer cipher a plan at 1976 by IBM. New Directions in Cryptography, introducing the suggestion of public key cryptography in print by Whitfield Diffie on 1976. The Diffie-Hellman was stimulated on 1977, paper and acting as complete novices in cryptography, Ronald L. Rivest, Adi Shamir and Leonard M. To make a useful public key system had been discussing by Adleman. The full scientific report to anyone submitting a self-addressed, stamped envelope offer was included in the Scientific American article. An application for a New Block Encryption Standard a planned International Data Encryption Algorithm (IDEA) was published on 1990 by Xuejia Lai and James Massey in Switzerland. The warning by the FBI to require access to the clear text of the interactions of citizens. PGP (Pretty Good Privacy) was the unrestricted first description on 1991 by Phil Zimmermann. The earlier RC2 and RC4 algorithms included in RSADSIs BSAFE cryptographic library the author was Professor Ron Rivest on 1994. The user can vary the block size, number of rounds and key length, if the algorithm uses data-dependent rotation as its non-linear operation and parameterized. Introduction to Encryption Systems Encryption is a process to encrypt the messages that can be readable by the person who knows how to decrypt the messages. This method has been used for over 2,000 years. The encryption is refers to the translation of a data into a secret code by using the algorithms. In the science of cryptography the process that involved is encryption. The messages must be securely sent. These messages could be numeric data, text or secret codes. For example, Missile Launch Codes. This encryption systems providing privacy for the authorized peoples communications. The receiver must have a key to decrypt the message to return to its original plain text form. The key that use to decrypt the message is trigger mechanism to the algorithm. Nowadays, encryption systems is the advent of the internet and public used it rarely. Moreover, these systems became largely military tool. There are used this systems in many field. Such as banking, online marketing, healthcare and other services. Even the average householder is aware of the encryption. When an address beginning with https that shows that web browsers is encrypt text automatically when connected to a secure server. When connected to a secure website, even the browsers automatically encrypt the information but many of them still choose the use of the encryption to do their email. The feature plug-ins or interfaces for the popular email clients will be easily accomplished with the help of encryption program. The most popular and longstanding is called PGP (Pretty Good Privacy), a name for very strong military-grade encryption program. It will be allowed to not only for the messages, but also may used for the personal files and folders as well. When the information tra vels between the computers, interception of the transmission that cannot be readable because it was in unreadable gibberish. Even there are many types of encryption but not all types of encryption are reliable. Other than that, there are same computer that yields strong encryption that can be used to break weak encryption schemes. Earlier years, they used 64-bit encryption and they taught that was quite strong but it was break by the 128-bit encryption. This is the standard encryption and this will not change in the future. It was undoubtful.The data makes private by the strong encryption. But, it is not compulsory will be secure. If the used data wants to be secure, the recipient must be positively identified as being the approved party. The digital signatures or certificates are usually accomplished online. Types of Encryption The encryption consists of 5 types of encryption systems. There are manual encryption, transparent encryption, symmetric encryption, asymmetric encryption and email encryption. Firstly, manual encryption. This type of encryption involves the use of the encryption software. This encryption encrypts the computer programs in various bits of information digitally. Users participation must completely involve in this encryption. If the wants to encrypt the file, the user have to choose the type of encryption from a list that provided by the security system. This may use in the personal computers. For the reason that is the user easy to encrypt the personal files in a way they like, and also it will be protecting the personal material on a computer. Secondly is the transparent encryption. This encryption can be downloaded onto a computer to encrypt everything automatically. This is the most protected type, since it doesnt leave out anything. The computer has an encrypt duplicate in every ex ecutable appliance and folder that formed endure authority surges and defends information in casing a computer is stolen. In addition symmetric encryption also defined as one of the type of encryption. By using this type of encryption can easily encrypt information by own self. For an example, a letter or number coincides with another letter or number in the encryption code. The code can make by ourselves. Such as a=1, b=2 and so on. Besides that, asymmetric encryption is a safe and easy way that can be used to encrypt data that will be receiving. This type will do by electronically. The public key can be seeing by whoever want or post somewhere. Others can encrypt the information and send it back. There is also another key even the public key decipher that is private key. This key has only one person have. This means the data will encrypt by public key but it can be read only by the whomever has the private key. Lastly the email encryption is typically same as asymmetrical encryption method. This method is the emails that in inbox cannot be read by others especially by the hackers. There are 2 types of email encryption. The result in who gets the private key to the email is the first an email supplier. The client of an email address is given by regularly. The second type is managed over who gets the key gives by the user. This way the encrypt emails can read by others who have the private key given. Types of Encryption Software There are two main encryption-software types: Disk-encryption software, which protects mutually programs and data Data-encryption software, which protects just data Disk Encryption Software This type of software also called as full-disk-encryption software that used to protects the complete hard drive. This including the operating system, all software programs and its folders and files except for the MBR (Master Boot Record). Disk encryption hardware will protect the whole hard drive as well as MBR. This software no needs to buy, it will be already contain in a new computer or upgrade to a new operating system. For instance, Microsoft Vista and Windows 7 Enterprise and Ultimate editions. This software will protect the computer when not using it only. The laptop must switch off when not using it. Data Encryption Software This type of software will protects the chosen folders and files in an implicit vault, volume Or safe. In the computer must be store all the sensitive data in a virtual vault. When the virtual vault is closed only the data encryption software will protects the data. Whereas not actually working on any data within it should always closed the virtual vault. Process of Encryption 1The Encryption Process Binary message is very simple process of encryption The binary message is simply xored with another binary sequence The second sequence must be random Example: Let the message be ECE 101 Using ASCII encoding, we get: 45x 43x 45x 20x 31x 30x 31x In binary form: 01000101 01000011 01000101 00100000 00110001 00110000 00110001 Now select a random sequence of equal length, example: 1010011 1000011 0101101 1101110 0110010 1010001 1101010 The encrypted message is then: E C E SPACE 1 0 1 45x 43x 45x 20x 31x 30x 31x 1000101 1000011 1000101 0100000 0110001 0110000 0110001 $oplus$ 1010011 1000011 0101101 1101110 0110010 1010001 1101010 = 0010110 0000000 1101000 1001110 0000011 1100001 1011011 16x 00x 68x 4Ex 03x 61x 5Bx SYN NULL h N ETX a [ 2The Decryption Process To decrypt the encrypted message it must be xored with the same random sequence that was used for encryption. SYN NULL h N ETX a [ 16x 00x 68x 4Ex 03x 61x 5Bx 0010110 0000000 1101000 1001110 0000011 1100001 1011011 $oplus$ 1010011 1000011 0101101 1101110 0110010 1010001 1101010 = 1000101 1000011 1000101 0100000 0110001 0110000 0110001 45x 43x 45x 20x 31x 30x 31x E C E SPACE 1 0 1 Fundamentally, this works because $0 oplus 0 = 0$and $1 oplus 1 = 0$ $x oplus 0 = x$, for x=0 or x=1. 3Comparison of secret key and public key cryptography Uses of Encryption There are five uses of encryption: Uses of encryption Details Confidentiality The person correspondent or the recipient can normally be implicit of encrypted data Error Detection The inside of the message have not unintentionally changed will be checking User Authentication The recipient that the correspondent is the real creator and not someone else by the verification Message Authentication The messages have not been lost or interfered with when do the verification Proof of Origin The message came from the declared correspondent is providing to the third party Types of Encryption Algorithms There are six types of encryption algorithms. They are RSA, DES/3DES, Blowfish, Idea, Seal and RC4. The key length is discerned by the strong encryption used the algorithms. RSA The idea of a public key system was proposed in 1977. After, this proposed the 3 mathematicians, Ron Rivest, Adi Shamir and Len Adleman give a concrete example of how the method can be implement. A private and public key was used by this system and this method refers to RSA Scheme. This system used the term n=p*q. DES/3DES U.S was developed and endorsed the Data encryption Standard (DES) in 1977 as official standard form. A block cipher with 64-bit block size that uses 56-bit keys by DES. Some of them not concern about the DES secure. The Triple-DES (3DES) has emerged with a strong method. With the help of DES/3DES giving it a cumulative key size of 112-168 bits. BLOWFISH This is like a symmetric block cipher same as DES or IDEA. The blowfish was created on 1993 by Bruce Schneier. Then it gets acceptances as a strong encryption. IDEA On early 1990s the International Data Encryption Algorithms (IDEA) by Dr.X.Lai and Prof.J.Massey in Switzerland replacing by the DES standard. This system uses encryption and decryption at 8 bytes in a time. SEAL In 1993 Software-optimized Encryption Algorithm (SEAL) was designed by Rogaway and Coppersmith. Block Ciphers is slower than Stream Ciphers. This SEAL is considered very safe because it has 160 bit key. RC4 Ron Rivest was invented RC4 cipher. Commercial systems like Lotus Notes and Netscape was used this cipher. This cipher used 2048 bits (256 bytes) key size. It relatively fast and strong ciphers. Advantages and Disadvantages Encryption is playing a most important role in day-to-day. Even it play role in important, there also have some negative points. Advantages Disadvantages The information that stored in the computer from not permitted access-even from people who not have access the computer system that can be defend An aggressor can cooperation the encryption series itself The transmission from one computer to another computer can protect the information An aggressor might find a earlier anonymous and comparatively simple way to translate messages encrypted with the algorithm that using The data can be used to deter and detect accidental or intentional alterations The deleting all the data cannot be prevent by attacker To know the author of the document can be verify Before it is encrypted or after it is decrypted could access the file by attacker Cryptography VS Encryption Cryptography Encryption The science and study of secret writing is defined as cryptography The desktop-computer insurgency has made it likely for cryptographic techniques to become widely used and accessible to no experts Cryptography is a part of the history, on the ancient years complex based codes and algorithms and machines was created By having some secure communications the Enigma machine was developed by Germans, throughout the World War I The secret Ultra project through World War II was Enigma codes that decrypted by the British Users suggestion is always encryption of the unbelievable on system, or the holder or the law of the enforcement This system changed a plaintext to the cipher text, which always has the look of casual The encrypted form called as cryptogram, the process of the encryption will be determined by the encryption algorithms The transformation will be truthfulness, genuineness and privacy provides by the encryption The information that send by the A is authentic and has not been tampered Algorithm Compression Loss Authenticity IEDS No No Yes SCAN Yes No No MIE No No No CIE No No No VQ Yes No No DRP No No No VC No Yes No 4Figure 2.1 Image Encryption Algorithm Property Comparison Table Importance of Encryption This is a very mysterious subject. The administration seems have no realistic application outer surface. The computer has distorted the age. In this world has do whole thing was recorded on computers that was connected to the Internet. There are many areas use encryption: The outsiders cannot snatch a copy of the transit that will assure by the encryption. The transit will be going between the commerce with many places of work locations needs to send computer data files among themselves. The encryption system allows them to hide the information among themselves when dissimilar people share the computer system. But nowadays almost they share similar in some form. The possible document only can read by the person who designed the encryption. Even others have the physical access to it. This issue modified encryption keys to the people. If everybody keeps their personal data in encryption form, this was worried by the law enforment authorities. Because of this, they tried a limit of using the strong encryption by the general public. The encryption software treats as military ammunition by the laws of the United States of America and it will be allowed export with case-by-case permission from the government. Examples of Encryption There are few examples of encryption. This example can easily break by the unauthorized people. By this examples, can understand more about the encryption. Reverser Decode EncodeThis type will be the reverse of whole message. If someone want to look the encrypted words, they can see the words by the backwards. Example: hello olleh hello Shifter Decode EncodeThe letters incremented by one so a becomes b, b becomes c and so on. The message will be more easier when incremented. By this type of encryption also others can see the letters. Example: hello ifmmp hello Flipper Decode EncodeThis is done by flipping every two characters. This is done by switched the 1st and 2nd letters, 3rd and 4th letters and so on. This also easy to encrypt the letters again. Example: hello ehllo hello Caesar Cipher Decode EncodeThis was made by Julius Caesar. This can be seen in the history. This also can be easily broken. The encrypted message is being used to replace the real message. Example: hello khoor hello Challenges and Technologies 5The encryption is very useful to the worldwide. Even it is useful, there are some challenges that faced by the encryption: GLBA compliance and emerging technologies by Paul Rohmeyer, Contributor The second decade of managing information risks under the regularly oversight of Section 501. RSA 2008: Financial industry security challenges The unique security challenges facing the financial industry its talks by the Executive Director Ed Zeitler. This can put strain on IT. Overcoming USA Patriot Act challenges This was contributors by Michael Rasmussen and Michael Landers. The authority to regulate various activities of financial institutions and they required them to maintain anti-money laundering programs. Regulatory and competitive forces The privacy laws are required to protect identity and personal financial information from unauthorized parties. Key management challenges and best practices This explains that to all procedures related to generation, exchange, storage, safeguarding, use and replacement of keys. BITS releases guide for implementing email authentication protocols 500s consumer-facing services brands adopted DKIM and Sender ID (SIDF), Microsofts version of SPF. The challenge is to locating all their sources of email. 6Other than that, there some technologies in the encryption. RSA encryption system was the top of the list, it developed by Ronald Rivest, Shamir, and Leonard Aldeman in the late of 1970 at the Massachusetts Institute of Technology. Security Sockets Layer (SSL) is a public-key encryption seems widely used in client-to-server applications. It was developed by Netscape and supported by Microsoft browsers. This SSL was suffered from its complex computation system, which prolongs the time it takes to perform the encryption and decryption processes. Besides that, Pretty Good Privacy (PGP), also a technology was developed by Phil Zimmermman. It was released on 1991. This was easy to use and strong encryption. After 1996, PGP was launched as commercialize the software. Then, Zimmerman man continued to develop more the PGP. There are some companies operating over a large network to protect the information on their hard drives, the program was Symantec Corps Norton Your Eyes Only. On 2000, Wi ndows 2000 was equipped with automatic encryption schemes. Alternatively, the programs could encrypt data onto a company server and allow with authorized access the files to decrypt them. 7Language that used to develop the encryption The application in programming language must be in order form to develop it. There are two popular and relevant high level programming languages that is Java and C#. The features in terms and portability were compares between Figueroa n.d. and Java and C#. By this comparison can be identify which has the better performance in processing images. The both languages are portable based on the study. The architectures and operating systems in different to run a program in flexibility is refers to portability. The term of the programming languages was only portable for C#. Java in the other hand is portable for in source code, hardware and OS. When manipulate the image is converted into matrix where elements of the matrix represent a pixel of the image. There are two types of size, they are vector size and matrix size. C# is faster when both sizes are greater than 4096. Java is faster when processing small sizes. 8Technique of encryption Younes Jantan, 2007 has proposed a simple and strong method for image security using a combination of blocks based image transformations and encryption techniques. The original message divided into blocks, which is rearranged into a transformed image using a transformation algorithms and then transformed image is encrypted using the Blowfish algorithm. Without the key, encryption and decryption process cannot take place. The following figure shows the model of the proposed technique: Original Image Key Transformation process Encryption process Ciphered Image   Figure 2.2 An Overview Diagram of the Proposed Technique Depending on the key supplied by the different cipher codes have the similar image. The confidentiality and security will provide when the image based data transferred with the help of suitable user-defined key. The resulting image will not be generated because of the result of hash embedded inside the image file. The below figure shows the architecture proposed: Image Encryption Model Image Cipher Code (An encrypted image) User Defined Key Decrypted (Original) Image Image Decryption Model User Defined Key Figure 2.3 The Architecture of the Image Encryption and Decryption Model Future Improvements The future of encryption is brighter than ever before. The protection of corporation information assets and third-party information is increasing spectacularly and it is demand for more control. Even five years ago, the amount of information being communicated and stored by electronic means is hugely great. The information security products are growing at a higher rate than any other aspect of IT technology must be more effective within the enterprise today. From the perimeters of communication, the Internet and the mobility of its users have removed it. For the modern day enterprise the last line of the defense is encryption. In future, the encryption systems will be more useful to the users. Moreover, this encryption is tough, complicated, jargon and it is not user friendly. Even, by the IT people also cannot know what is actually encryption. How about the the common people. Many of them said that encryption is so great, why Microsoft did not use this. Because it is very expansive, too advance for the unknowledgeable persons and is not simple to use it. In future, the encryption will improve the PIN security. The unique encryption key can be used only by the EFT networks members only. But this costs high implementations, since some of the ATM owners ignored it. The remote key distribution may improve the compliance rates. There are 6 critical market drivers that will be the shape the future encryption  [9]  : Email privacy and regulatory requirements The global enterprises provided easy way exchange information can conduct the business electronically by the Internet and adoption of Internet protocols. Increasing compromises and unauthorized access to critical business information To improve the quality and level of protection enterprise employ to guard their information assets and the assets of their customers and business partners. The expanding enterprise The increasing number of regulations are aimed in a part at ensuring enterprises maintain and fulfill their fiduciary responsibilities. User mobility Ensure that the information during travel safe and the electronic communication also remain safe as it is transmitted across the Internet. Communications appliances Credit card may need protected for much longer periods of time. The Art of Storing and Retrieving Corporate Information Assets There are emerging the solutions for how to communicate among the various enterprise members in a secure manner. Conclusions The future of the encryption will be using by electronically for the purpose of enterprise conduct business. In future the encryption and the innovation of the applications providers. At Backblaze is protecting the privacy of the users data is a top priority that means encryption system. This is easy to use as a key part of the vision and makes the product hard to use for the encryption. For the military grade encryption made easy by mix of the public/private and symmetric key algorithms. The encryption is refers to the translation of a data into a secret code by using the algorithms. In the science of cryptography the process that involved is encryption. The messages must be securely sent. These messages could be numeric data, text or secret codes. For example, Missile Launch Codes. This encryption systems providing privacy for the authorized peoples communications.

the black death Essay -- essays research papers fc

In â€Å"The Black Death† the author Phillip Ziegler attempts to fully describe the Plague that struck Europe in 1338 and remained until 1665. The year of the great Plague of London Ziegler tries to give an unbiased account of the Plague by compiling information from contradictory sources. Ziegler begins the book with the Tartans catapulting diseased corpses into Genoese as the Genoese escape back to Europe. Following this, the author provides some insight into the Plague in Italy, Germany, and France, in which he highlights the persecution of Jews, who became the scapegoat for the Plague in Germany. The majority of the book discusses the Plague in England, dealing with the people that died.   Ã‚  Ã‚  Ã‚  Ã‚  Ziegler doesn’t argue an opinion of his findings. He openly admits that he has done no original research. Instead, he presents a collection of materials and draws some conclusions based on their findings. Ziegler’s intention in writing â€Å"The Black Death’, is to provide an accurate an unbiased account of the plague that struck Europe in 1338, and to appeal to human emotions through eye witness accounts.   Ã‚  Ã‚  Ã‚  Ã‚  Ziegler begins with different accounts on how the plague arrived in Europe. After presenting a few ideas, poisonous fumes, or unburned or unburied corpses, Ziegler finds the real truth of the plagues origin in a bacteria known as Pasteur Ella Pestis. Pasteur Ella Pestis, which forms itself within the siles of the dead corpses, head foun...

Personal Narrative About Me :: Autobiography Essay, Personal Narrative

Me I am sentimental, out-going, indecisive, understanding, curious, naive, lazy, and young. I want to be ... , well a lot of things, and growing is discovering what they are. I feel people cannot see the potential within, although there is no one to blame but myself. I look to others for approval instead of to myself. I aim to please; it leads to approval. I don’t like to discuss my faults; I pity myself. I am weak in some respects, but in others I am strong. My life is a balance of ups and downs. With my extremes however, my scales never fulfill the word "balance." The ups and downs equal a median on which I travel daily. I love those who understand me, who chose to come close to the fire, who stay long enough to love its warmth, and who know how to avoid being burned. I don’t trust people easily. I don’t throw around my heart. I’ve lost love from my lack of giving. I regret this. I grab hold of things, always seeking support, a rock on which to lean. I have tried God, boyfriends, and small successes in school and sports, feeling the title FAILURE rise upon my forehead when I slipped. Afterwards I tried even harder to bring myself back up, my recovery taken on the quickest, most unstable route. This explains how I fell so easily. The self-esteem I had needed to be constantly replenished and refilled. My source was not myself, but others, whose opinions mattered more than my own. I am passionate and at times fearless. I am everything, and I am nothing. I am ever-changing and unpredictable. I crave security but cry for independence. I am black or white, never gray. My actions may not reflect my feelings and vice-versa. I play the submissive female one minute and the aggressive female the next. Every year I learn more about myself. The person inside no longer takes peeks at the world outside, but screams "Look at me, see what I’ve become, watch because I am coming!" I’ve been through difficult times, but the odds are starting to lean my way; I feel ready for any challenge that may arise.

Rebuttal on Mark Twain’s the World Is Not Civilized Essay

Mark Twain says that the human race I cruel, and uncivilized. Unlike the animals, humans have the ability to care for those who are weak, sick, and otherwise unfortunate. In the wild if an animal is sick or weak, they are abandoned by their own species and are, ultimately, a source of food for another. The wounded are killed without a hesitation. Man has compassion, not only for our species but for the others. There are many organizations that are created to help people in need. There is the Red Cross that steps in during an emergency to provide shelter, blood and food to those who need it. There are homeless shelters that take in the homeless to shelter them from the elements. There are soup-kitchens that feed the homeless. There are children’s homes that provide a safe place for orphaned or abandoned children to grow up. There is Breast Cancer Awareness, AIDS foundations, and a society to end world hunger. All of these organizations are founded to help someone or something that is in need. Twain says â€Å"I was aware that many men who have accumulated more millions of money than they can ever use have shown a rabid hunger for more, and have not scrupled to cheat the ignorant and the helpless out of their poor servings in order to partially appease that appetite†. Even though it may be true that rich men want to get richer, the wealthy people are the ones that are most charitable. Bill Gates and Warren Buffett, two of the richest men in America, give millions of dollars annually to various foundations and charities that help people all over the world Man also helps the animals. There are many organizations that help animals and the planet. Some of those include PETA and Green Peace. We even try to help the earth. New inventions are being created just to help the earth. They start business just to keep specific animals from going extinct. We share and support other countries. When the hurricane in Haiti happened people helped. Resources were given because of the generosity of man. When countries are in need they are helped. When the flood came to Tennessee the people gave some time for community service. Some people that didn’t get hit by the flood could have done nothing but they decided to help others. Man created governments to stop the fighting. Laws were created in order to have a calm and safe environment. Man Negotiates to prevent wars and battles from happening. We also come up with compromise and treaties in order to get peace. For example the Treaty of Versailles was ratified after negotiating and finally coming to a compromise. We don’t just go ahead and fight who ever walk across our territories like the lions.
