A personal Authentication Based on IRIS Recognition
ABSTRACT
Iris recognition is the process of recognizing a person by analyzing the apparent pattern of his
or her iris. There is a strong scientific demand for the proliferation of systems, concepts and
algorithms for iris recognition and identification. This is mostly because of the comparatively
short time that iris recognition systems have been around. In comparison to face, fingerprint
and other biometric traits there is still a great need for substantial mathematical and computervision
research and insight into iris recognition. One evidence for this is the total lack of publicly
available adequate datasets of iris images.
The program converts a photo of an eye to an 'unrolled' depiction of the subject's iris and
matches the eye to the agent's memory. If a match is found, it outputs a best match. The
current functionality matches that proposed in the original requirements.
Introduction:
A biometric system is essentially a pattern recognition system that operates by acquiring
biometric data from an individual, extracting a feature vector from the acquired data,
comparing this feature vector from the database feature vector. Person authentication has
always been an attractive goal in computer vision. Authentication systems based on human
characteristics such as face, finger, iris and voice are known Biometrics systems. The basis of
every biometric system is to get the input image and generate prominent feature vectors like
color, texture, etc.
Taking a Picture:
An iris recognition camera takes a black and white picture from 5 to 24 inches away, depending
on the type of camera. The camera uses non-invasive, near-infrared illumination (similar to a
TV remote control) that is barely visible and very safe. Proof Positive certified cameras are in
compliance with all applicable international illumination safety standards, including ANSI/IESNA
RP-27.1-96 and IEC 60825-1 Amend.2, Class 1 LED. These are the latest worldwide standards.
Unlike other biometric technologies that can be used in surveillance mode, iris recognition is an
opt-in technology. In order to use the technology you must first glance at a camera. Iris
recognition cannot take place without your permission
