Enhancing Security of Stored Biometric Data

a biometric system is weak to a different type of attacks targeted at undermining the reliability of the verification process. These attacks are either imposter or irrevocability. Imposter means information stored in database, can be abused to construction of artificial biometric and replace it for fake authentication and irrevocability means once compromised, biometric not be updated, reissued or destroyed. In this paper we present a general architecture with the help of Digital Signature that guarantees privacy protection of biometric data. We specifically focus on secure a biometric data at the time of authentication and storage.
