Biometric cryptosystem provides a seamless connection between the biometrics and traditional password, and it represents a new development in the next generation cryptography. Even if the biometric cryptosystem is secure in algorithmic design, it may still be vulnerable to side-channel attack due to the physical leakage. To assess the possible side-channel attack on biometric cryptosystem, a se...

Biometric-based techniques have recently emerged as a trustworthy and effective approach of user authentication; however, unlike conventional authentication methods such as passwords and tokens, if an enrolled biometric template is compromised, usually it cannot be revoked or re-issued. In this paper, four naive cancelable techniques, namely, shifting, password-dependent shifting, XOR and addin...

In this paper, we propose a new finger multi-biometric cryptosystem using feature-level fusion to simultaneously protect multiple templates of fingerprint, finger vein, finger knuckle print and finger shape traits as a single secure sketch. We theoretically analyze the featurelevel fusion for finger multi-biometric cryptosystem with respect to their impact on security and recognition accuracy. ...

-Biometric authentication system are used prevalently for its template security, retract ability and privacy. The Authentication process is reinforced by biometric cryptosystem. We propose a demonstrable secure and blind biometric authentication protocol which discloses only identity and not any other information to both client and server. To reduce the computational cost and enhance security w...

Bio-Cryptography is a progressive technology that combines biometrics with cryptography. It is a method using bi...

Biometric based cryptography system provides an efficient and secure data transmission as compare to the traditional encryption system. However, it is a computationally challenge task to solve the issues to incorporate biometric and cryptography. In connection with our previous works, this paper reveals a robust cryptosystem using iris biometric pattern as a crypto-key to resolve the issues in ...

In this work we present an iris-biometric cryptosystem. Based on the idea of exploiting the most reliable components of iriscodes, cryptographic keys are extracted, long enough to be applied in common cryptosystems. The main benefit of our system is that cryptographic keys are directly derived from biometric data, thus, neither plain biometric data nor encrypted biometric data has to be stored ...

The Biometric Gaussian Stream (BGS) cryptosystem was extended by extensive research experimentation. Using this system, complexity is added to an image by passing it through a Gaussian noise function. This function is applied with specific parameters for the mean and variance, which also works as a parallel key. To implement a stream cipher BGS with help of biometric images, the Initial Conditi...
