A Hybrid Approach for Biometric Template Security

Abstract

Privacy and Security has become an increasingly serious ýproblem for any biometric systems. Template protection, ýwhich mainly prevents from data loss and hacking the stored ýtemplates, is one of the most important issues when considering ýprivacy and security. Cancelable biometrics approach Scheme ýhas been proposed to address this problem. On the other hand ýthe symmetric hash functions might be used to increase the ýbiometric security level by making it is hard to attack the ýtemplate. In this paper, a new hybrid approach based on ýcombining approaches based on transformation and ýcryptosystem on fingerprints is applied. The results are ýcompared to a pre-presented approach in [1] showing that the ýnew approach is more efficient as the security of biometric ýtemplate is increased meanwhile the error rate is minimized.
