Abstract

An iris recognition system, more secure and practical, be proposed by the combination of chaos encryption and iris recognition. In the process of iris recognition, using multi-scale 2D Gabor filter to acquire the identify code of iris texture only in single-direction. To protect the identify code be transported securely, one-way coupled map lattice (OCML) chaos system be applied to generate pseudo-random number key stream, and the iris identify code will be encrypted and decrypted based on the method of ciphertext feedback. Finally, using Hamming distance to finish iris classification. Experimental results show that the system provides a high recognition accurate and high encryption speed.
