Biometric cryptosystem has gained increasing attention in recent years. One of the difficulties in this field is how to perform biometric matching under template protection. In this paper, we propose a key binding system based on n-nearest minutiae structures of fingerprint. Unlike the traditional fingerprint recognition method, the matching of nearest structures are totally performed in the en...

Multibiometric systems are being increasingly deployed in many large scale biometric applications (e.g., FBIIAFIS, UIDAI system in India) because they have several advantages such as lower error rates and larger population coverage compared to unibiometric systems. However, multibiometric systems require storage of multiple biometric templates (e.g., fingerprint, iris, and face) for each user, ...

By adopting a non-interactive information-theoretic secure verifiable secret sharing scheme in an unorthodox way, a verifiable fingerprint vault scheme is presented in this paper. Fuzzy vault scheme is a novel cryptographic construct which can increase the security of the biometric template in a biometric authentication system. It can be also used to bind the cryptographic key and the user in a...

-This paper presents a narrative key generation scheme using biometric methodology for providing high security over the internet applications such as VoIP technology. The present work deals with modern computing systems security issues, focusing on biometric based asymmetric key generation process. The term VoIP refers-“voice over internet protocol (IP)” in which the “voice” to be transmitted u...

Smart environments established by the development of mobile technology have brought vast benefits to human being. However, authentication mechanisms on portable smart devices, particularly conventional biometric based approaches, still remain security and privacy concerns. These traditional systems are mostly based on pattern recognition and machine learning algorithms, wherein original biometr...

Our modern day era faces an inevitable problem of securing our most integrated data and messages. The chief problem is to protect our data in a unique way that could only be worked upon by the sender and the recipient. Most of the traditional techniques probably in-use today, emphasizes on keys that are generated by generic function, algorithms or in random key generators. But question remains ...

Iris recognition is a proven, accurate means to identify people.An efficient method for personal identification based on the pattern of human iris is proposed in this paper. Crypto-biometrics is an emerging architecture where cryptography and biometrics are merged to achieve high level security systems. Iris recognition is a method for biometric authentication that uses pattern-recognition tech...

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...
