As stated in ISO/IEC JTC1 SC37 biometrics is defined as the automated recognition of individuals based on their behavioural; and biological characteristics. As discussed in section-------(Intro to biometrics) the main process involved in biometric recognition are Enrollment and Verification or Identification in general called as recognition. During the Enrollment process features of the captured biometric entity are converted to template, to be stored in database for further matching. At the stage of recognition , template obtained from the features of the realtime biometric entity are compared against the stored template. The result of matching process involved in recognition is either accept or reject[1]. It has been a long time belief that the biometric signals or data cannot be reconstructed from the stored templates but Cappelli et.al and Ross et.al[2][3] has proven that the belief of biometric data reconstruction from the templates is possible. In order to protect the biometric data , several standard encryption algorithms has been used. But, this attempt leaves the biometric templates exposed during every authentication attempt[4]. Even homomorphic and asymmetric encryption schmes [5][6][7] represent some exceptions. Conventional cryptosystems is based on the possession of secret keys and key management is performed using second layer authentication entity like password[8]. Decryption keys in this scheme could be obtained by using the password. To overcome the drawbacks of the existing schemes, biometric template protection schemes which are commonly called as biometric cryptosystems also referred to as Helper data-based scheme are proposed. Two major requirements of biometric information protection as per ISO/IEC FCD 24745 standard are,
• Irreversibility
Reconstruction of original biometric template from the stored template should be made difficult whereas construction of protected biometric template from the stored template should be made easy.
• Unlinkability
Several different versions of protected biometric templates can be generated based on the same biometric data, which is referred to as renewability whereas the protected templates should not cross-match, which is referred to as diversity.
Biometric cryptosystems herein after referred to as BCS are designed to securely bind a digital key to a biometric or generate a digital key [9]. BCS paves way for the growth of biometric dependant key-release and biometric template protection [10][11]. BCS is more difficult to forge, copy, share and distribute biometric data when compared to that of passwords [1]. Conventional biometric cryptosystems perform fuzzy comparisons by applying decision thresholds. Decision thresholds are obtained based on the score distributions between genuine and imposter subjects, whereas BCS gives only stable keys as output , which are required for matching at the authentication stage.
What forms Our Identity is individualization, no one is a carbon-copy of one another and there are many things that makes each person unique whether that be their ethnic background, personality, religious beliefs which can range from Non-religious, Christian, Muslim, Buddhist, Etc; In the book Uglies by Scott Westerfeld the book is set three hundred years into the future, with the government giving surgical operations which provides every citizen with the “Pretty” operation which makes everyone meet the standard of societal beauty.
Patient personalized health cards are also long underling technology that might provide patient a freedom of owning his/her PHI. Transferring data from one hospital to another wouldn’t be a challenge with this password protected health cards. Privacy wouldn’t be much of an issue as all the information is stored in the chip of the card that can be retrieve by a healthcare provider or by patient when needed.
Many countries around the world have laws on what information a government can ask from its citizens. These laws typically focus on protecting the privacy of individual citizens and preventing discrimination based upon the collected information. Computer matching could place this same information in the hands of the government.
Biometric and encryption sounds are not too fresh, for most users, any of each technology alone is not enough to make you feel excitement. However, If we develop a new study or a new technology, which combine the biometrics and encryption. We can find that the technology combining these two techniques are very amazing.
Biometrics is described as the use of human physical features to verify identity and has been in use since the beginning of recorded history. Only recently, biometrics has been used in today’s high-tech society for the prevention of identity theft. In this paper, we will be understanding biometrics, exploring the history of biometrics, examples of today’s current technology and where biometrics are expected to go in the future.

After the September 11, 2001, terrorist attacks the biometric community has made vast technological improvements in protecting the United States and its borders (The Biometric Consortium, 2012). Biometrics is an automated method of recognizing an individual based on a physiological or behavioral characteristic. Biometrics includes features such as face, fingerprints, hand geometry, handwriting,
Biometrics has really been a captivating part of watching new age movies and futuristic stars bring in the 21st century. Yet, most regular people don’t even know what is behind these alluring “tricks”, and what really classifies as a part of the Biometrics field. Something as simple as a pin number you use for an ATM machine would qualify as part of this realm. Other behavioral characteristics can be things such as a voice print, or a signature. Biometrics can also become so technologically advanced that they can use video surveillance to scan who goes in and out of an area...
Biometric technology is used for the ways humans can be identified by unique aspects of their bodies, such as fingerprints, body odor, our voices and many more. If one was to think about privacy rights, he/she would be concerned about the widespread adoption of these systems, since such systems could easily be used to develop a record of known rebellious people and/or dangerous criminals, to be used for social control purposes. Although that may seem pretty good and a positive thing for the society, one should take into account of the defects and errors of technology. Of the many biometrics technologies that are being developed and are already developed, facial recognition is one of the most threatening because it can be deployed secretly; one may not know whether or when they can be caught in a surveillance camera for such facial recognition biometrics. Additionally, tests have found that the miscalculations for facial biometrics technologies are very high. As a result, according to Privacy Rights Clearinghouse, innocent people can be erroneously identified as dangerous criminals and actual dangerous criminals and/or suspected terrorists can fail to be detected overall, allowing for a huge injustice and unfairness. Privacy rights concerned with biometrics have sparked a concern and should be dealt with; otherwise, this is just one of the
Computer science is a vast field that includes nearly everything relating to computers. Everyday there is information transmitted all over the Internet. Pictures are uploaded, transactions are made on thousands of online retail websites, and banking transactions take place everyday on the Internet. All of these transactions have created a need for secure communications. People wish to keep things like banking, medical, and political information from the eyes of unwelcome parties. This has created a need for cryptography. Cryptography is the science or study of the techniques of secret writing, especially code and cipher systems, and is used by everyone from the average citizen to the government and military.
Distinctiveness refers to whether an individual displays different behaviors in different situations. What we want to know is whether the observed behavior is unusual. If it is, the observer is likely to give the behavior an external attribution. If this action is not unusual, it will probably be judged as internal.
As one of the feature of biometric, signature verification is used to find the authenticity of a person to give the access the most valued and important documents and shelf. Firstly the signature of a person are taken as a reference in database. To generate the database, number of attempts from the same person has been taken, as it would permit minute deviations in signatures that generates due to environmental conditions. Once it is done, then the signatures at other times are every time then verified with the existing database. Because of confidentially of the file/document/transaction giving access is the crucial process that should be monitored with perfection. The same happens with offline signature verification. Computerized process and verification algorithm (thus software) takes fully care of signature under test, generate results that are 100% authentic, and advocates credibility of the concerned person .However, there might raise issue of authenticity even if the same person performs the signature. Or, at times a forge person may duplicate the exact signature. Many research have been done to find the accuracy of result so as to prevent from forgery. Forgery is also divided into different categories depending upon their severity as
The variations of them have to change to be concrete and abstract. So they will mix
“The term -information security- means protecting information and information systems from unauthorized access, use, disclosure, disruption, modification, or destruction” (United States Code, 2008). In order to ensure the identity of who is trying to access the information, the concept of “Biometric Technology” has been developed in the last years. This essay will start explaining this concept and the characteristics of its development through the time. Then, the essay will offer a brief explanation of biometric systems operation and a description of different biometric systems developed until now. Finally, this research analyzes the current and future applications and the issues that surround it.
