ABSTRACT
Biometrics is a technology that mechanically authenticates, identify, or verify an individual based on physiological or behavioral characteristics. This is accomplished by using reck peerlessr technology in a non-invasive way to match patterns of lie in individuals in real time against enrolled records. The commonly subprogramd Biometric techniques allow credit of faces, hands, fingers, signatures, voices, fingerprints and irises for a persons identification and authentication. This piece of music discusses in detail the Iris Recognition as a Biometric Technique.
The iris being a protected internal electric organ whose random texture is stable throughout life shag serve as a kind of living password that one need not remember but one always carries along. The rich details of iris patterns are captured by high resolution imaging systems. The iris recognition systems use executable software, which deploy algorithms for encoding and recognizing iris patterns.

The recognition prescript is the failure of a Test of statistical independence on iris phase structure encoded by multi-scale quadrature wavelets. The combinatorial complexity of this phase information across different persons spans about 244 degrees of freedom, whereas, the crush fingerprint technology uses only about 60 to 70 degrees of freedom. This implies that the randomness of iris patterns has very high dimensionality and thus the recognition decisions are made with confidence levels high enough to brave out rapid and reliable exhaustive searches through national-sized databases.
The purpose of this topic is to provide an overview of the processes involved in iris recognition including the localisation principle of the iris in the image, the extraction of phase information and the shield of statistical independence.
