Global processes have strongly impacted development of biometric identification technologies in recent years. Today, Biometric technologies are one the most dynamically developing field of Information Technology.
These systems operate on the principles of recognising and remembering unique characteristics of the face, converting them into a special digital format. The advantage of such digital format is that it speeds up the search for face features in large biometric databases, allows one to use not only photographs, but also other methods of depiction (artist’s photo or photo-robot), which protects the confidentiality of the format.
Hand-based identification is technologically similar to fingerprint identification methods and allows one to search databases at high speed. Mathematical model of this identification method is limited to only 9 bytes of information. Other parameters of the hand are also used for identification.
Hardware and software tools for iris identification have been available for few years now. There are two blocks of technology in this direction – identification according to the shape of the pupil and identification according to the retina. The advantage of the former is that the identification of the pupil can be done remotely through a camera.
A person’s fingerprint is formed by papillary lines on the finger. These lines have the following properties, creating various patterns:
Exactly these properties allow one to use fingerprints as a unique identifier.
