Biometric Template Security

With the large scale deployment of biometric systems, a number of security and privacy issues are arising. It was shown that the stored fingerprint minutiae templates can be used to reconstruct the whole fingerprint and thus spoof fingerprints can be easily created to compromise the systems. Further, cross-linking of databases would be possible leading to privacy compromise. To curb such vulnerabilities of a biometric system, a number of template protection techniques are designed that either allow template revocation (called feature transformation based techniques) or keep the system secure even if the stored information is leaked (called biometric cryptosystems). Still significant advances are being made to design techniques that satisfy requirements of revocability as well as biometric cryptosystems and still have high matching performance.
