An offline signature-based fuzzy vault (OSFV) is a bio-cryptographic implementation that uses handwritten signature images as biometrics instead of traditional passwords to secure private cryptographic keys. Having a reliable OSFV implementation is the first step towards automating financial and legal authentication processes, as it provides greater security of confidential documents by means o...

Security concerns regarding the stored biometric data is impeding the widespread public acceptance of biometric technology. Though a number of bio-crypto algorithms have been proposed, they have limited practical applicability due to the trade-off between recognition performance and security of the template. In this paper, we improve the recognition performance as well as the security of a fing...

Multi-biometric system stores multiple templates for the same user corresponding to the different biometric sources. Infallible security should be provided to the stored biometric templates as biometric is not revocable. In this work, multi-modal biometric template security for palmprint and fingerprint is proposed which is based on the fuzzy vault generation. At first, the preprocessing steps ...

The emergence of body area networks (BANs) has paved the way for real-time sensing human biometrics in addition to remote control smart wireless medical devices, which turn are beginning revolutionize healthcare industry. However, due their limited power and computational capabilities, they vulnerable a myriad security attacks. To secure BAN sensors against these threats processor-intensive cry...

Due to the similarity of biological characteristics in image acquisition and physiological complementarity between the face and the ear, this paper proposes a hybrid face and ear multi-biometric template protection method, which firstly conducts a feature level fusion of the face and the ear feature vectors, and secondly transforms the fused features with a non-invertible function, and then uti...
