IRIS SCAN

A method for rapid visual recognition of personal identity is described, based on the failure of statistical test of independence. The most unique phenotypic feature visible in a personâ„¢s face is the detailed texture of each eyeâ„¢s iris: an estimate of its statistical complexity in a sample of the human population reveals variation corresponding to several hundred independent degrees-of-freedom. Morphogenetic randomness in the texture expressed phenotypically in the iris trabeclar meshwork ensures that a test of statisti ....etc

In todayâ„¢s information age it is not difficult to collect data about an individual and use that information to exercise control over the individual. Individuals generally do not want others to have personal information about them unless they decide to reveal it. With the rapid development of technology, it is more difficult to maintain the levels of privacy citizens knew in the past. In this context, data security has become an inevitable feature. Conventional methods of identification based on possession of ID cards or exclusive knowled ....etc

Biometrics refers to the automatic identification of a person based on his/her physiological or behavioral characteristics such as finger scan, retina, iris, voice scan, and signature scan etc. This method of identification is preferred over traditional methods involving passwords and PIN numbers for various reasons: the person to be identified is required to be physically present at the point-of-identification; identification based on biometric techniques obviates the need to remember a password or carry a token. The ultimate form of electroni ....etc

ABSTRACT
While magnetic and semi-conductor based information storage devices have been in use since the middle 1950â„¢s, todayâ„¢s computers and volumes of information require increasingly more efficient and faster methods of storing data. Among the most promising of the new alternatives are photopolymer-based devices, holographic optical memory storage devices, and protein-based optical memory storage using rhodopsin , photosynthetic reaction centers. This paper focuses mainly on protein-based optical memory storage using the photosen ....etc

Biometrics is an automated method of capturing a person?s unique biological data that distinguishes him or her from another individual. Iris recognition has emerged as one of the most powerful and accurate identification techniques in the modern world. It has proven to be most fool proof technique for the identification of individuals with out the use of cards. PIN?s and passwords. It facilitates automatic identification where by electronic transactions or access to places, information or accounts are made easier, quicker and more secure. The t ....etc
