IRIS RECOGNITION
Pattern recognition technique
Identification by mathematical analysis of the random patterns.
Based upon the qualities of the Iris.
![Page 28: Bio-metric Security System](https://reader035.vdocuments.mx/reader035/viewer/2022062903/58b891fe1a28ab3e3a8b5e2d/html5/thumbnails/28.jpg)
Iris is a protected internal organ whose random texture is stable throughout life
![Page 29: Bio-metric Security System](https://reader035.vdocuments.mx/reader035/viewer/2022062903/58b891fe1a28ab3e3a8b5e2d/html5/thumbnails/29.jpg)
IRIS PROPERTIES
High degree of Randomness
No two Iris are alike
Stable in a persons life
Doesn't vary with changes

BIOMETRIC PERFORMANCEFAR
The FAR is the chance that someone other than you is granted access to your account.
Low false acceptance rate is most important when security is the priority.
![Page 37: Bio-metric Security System](https://reader035.vdocuments.mx/reader035/viewer/2022062903/58b891fe1a28ab3e3a8b5e2d/html5/thumbnails/37.jpg)
BIOMETRIC PERFORMANCEFRR
The FRR is the probability that are not authenticated to access your account.
A low FRR is required when convenience is the important factor.
