RELIABLE BIOMETRIC AUTHENTICATION WITH PRIVACY PROTECTION

Abstract

Abstract. We propose a new scheme for reliable authentication of physical objects. The scheme allows not only the combination of noisy data with cryptographic functions but has the additional property that the stored reference information is non-revealing. By breaking into the database and retrieving the stored data, the attacker will not be able to obtain any realistic approximation of the original physical object. This technique has applications in secure storage of biometric templates in databases and in authentication of PUFs (Physical Uncloneable Functions). 1.
