Iris template security

Definition

 Template protection is a crucial requirement when designing a biometric based authentication system. It refers to techniques used to make the stored template unaccessible to unauthorized users. From a template, information about the user can be revealed. Moreover, identity theft can occur. Therefore, it is of dramatic importance, if a template is compromised, to cancel, to revoke, or to renew it. Template protection can be performed using  template distortion techniques, biometric cryptosystems, and  data hiding techniques. Template protection techniques specifically designed and applied to  iris images are hereafter summarized.

Introduction

Template protection is a key issue that has to be addressed when a biometric based authentication system is designed. It is highly desirable to keep secret a template both for security and for privacy reasons, and in case a template is compromised it is necessary to revoke, to cancel, or to renew it. Also,...
