SALTING SYSTEM AND METHOD FOR CANCELABLE IRIS BIOMETRIC

摘要

A system and method for generating a cancelable biometric includes providing at least one pattern and combining the at least one pattern with a biometric image by employing a transform pixel operation to generate a transformed enrollment such that information about the transform pixel operation and the at least one pattern form a security key for protecting the biometric image. The biometric image is reused to generate another security key in the event that the security key is to be canceled.
