Authentication Based on IRIS Recognition

Abstract :- :- 

 

Project Name  :-   Personal Authentication Based on IRIS Recognition 

          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 computer-vision 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.

What is the Iris

The iris is the plainly visible, colored ring that surrounds the pupil. It is a muscular structure that controls the amount of light entering the eye, with intricate details that can be measured, such as striations, pits, and furrows. The iris is not to be confused with the retina, which lines the inside of the back of the eye. 

No two irises are alike. There is no detailed correlation between the iris patterns of even identical twins, or the right and left eye of an individual. The amount of information that can be measured in a single iris is much greater than fingerprints, and the accuracy is greater than DNA. 

Iris Recognition

In less than a few seconds, even on a database of millions of records, the IrisCode template generated from a live image is compared to previously enrolled ones to see if it matches any of them. The decision threshold is automatically adjusted for the size of the search database to ensure that no false matches occur even when huge numbers of IrisCode templates are being compared with the live one. 

Some of the bits in an IrisCode template signify if some data is corrupted (for example by reflections, or contact lens boundaries), so that it does not influence the process, and only valid data is compared. Decision thresholds take account of the amount of visible iris data, and the matching operation compensates for any tilt of the iris. 

A key advantage of iris recognition is its ability to perform identification using a one-to-all search of a database, with no limitation on the number of IrisCode records and no requirement for a user first to claim an identity, for example with a card. 

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.
