How does iris recognition work?

Answer 1

the disadvantages of iris recognition is that a person who has a colour blindness or who are blind cannot pass through this iris recognition test.the advantages is that iris is an unique organ which all the people possess.

Answer 2

Iris Recognition

Iris is the ring-shaped region in the human eye that inscribes the pupil of an eye. Iris recognition technique employs the detection and comparison of the unique patterns of iris for every individual. It is designated as the fastest and most efficient technique that is capable of producing intended results in the least duration of time.

A biometric system is designed to follow certain biometric recognition algorithms, defined specifically for each different mechanism. While processing authentication, various parameters are to be considered, such as sufficient lighting when the image is being captured, proper posture of the person, image superiority, and various others. Each biometric system employs several modes or processes to authorize, these are feature extraction, sensing, and matching modules. The filtration mechanism is applied to pre-process the input image of the iris. The pre-processing of the input image is done to remove the noisy content from it. This is achieved by applying the collaboration of median filters. After filtration, the feature from the processed image is extracted by using the LBP-LDA technique. After extracting the features, the Artificial Neural Network is used to perform pattern matching. For purpose of performance evaluation, the proposed iris recognition is implemented in MATLAB.
