Abstract
Iris detection and recognition is widely applied in areas that require high security requirements. The iris can be used as a living passport in national border control system or applied as a living password, birth certificates, driving licenses, credit card authentication and enforcing internet security where controlled access to certain web pages is necessary. Iris recognition is considered as one of the ideal biometric recognition component. This project basically explains the iris recognition system implemented using Digital Camera and Multimedia Development Platform consisting of the Altera DE2-70 board, 4.3” LCD Touch Panel Kit(LTM), 5 Mega Pixel Digital Camera Module(D5M). This project involves finding out the best way to capture the best iris image taking the lighting condition and the object distance into consideration. The hardware control of the camera, display panel and DE2-70 board is written in verilog codes. Then, image pre-processing is performed followed by extracting the iris portion of the eye image. The extracted iris part is then normalized, and iris code is constructed using cumulative-sum method. Finally two iris codes are compared to find the Hamming Distance, which is a fractional measure of the dissimilarity.
