The Fuzzy Vault scheme is an encryption scheme, which can tolerate errors in the keys. This leads to the possibility of enhancing the security in environments where these errors can be common, such as biometrics storage systems. Although several researchers have provided implementations, we find that the scheme is vulnerable to attacks when not properly used. This paper describes an attack on t...

personal authentication and identification as compared to the traditional authentication methods. Biometric templates are vulnerable to variety of attacks due to their inherent nature. When a person's biometric is compromised his identity is lost. In contrast to password, biometric is not revocable. Therefore, providing security to the stored biometric template is very crucial. Crypto biometric...

In this work we place some of the traditional biometrics work on fingerprint verification via the fuzzy vault scheme within a cryptographic framework. We show that the breaking of a fuzzy vault leads to decoding of Reed-Solomon codes from random errors, which has been proposed as a hard problem in the cryptography community. We provide a security parameter for the fuzzy vault in terms of the de...

In this paper, fuzzy vault scheme is discussed for protection of templates in fingerprint recognition system. As fingerprint recognition system is most commonly used biometric, where minutiae points are stored as templates. If attacker gets this database, fake finger or artificial image can be created. Once biometric is compromised, it cannot be reused. This shows importance of template securit...

We investigate the security of a privacy enhancing technique for fingerprint authentication known as fuzzy fingerprint vault. This technique is based on the fuzzy vault of Jules and Sudan, a scheme that allows error tolerant authentication, while preserving the privacy of the reference data. We explore if and under what circumstances a secure fuzzy fingerprint vault can be implemented. We deriv...

According to the number of Internet in widely use and the development of the related application, the need of security system which can protect individual information has increased. Biometrics-based user authentication has several advantages over traditional password-based systems for standalone authentication applications. However, security of biometric data is particularly important as the co...

Biometric systems play an important role in authenticating the identity of an individual. Such authenticated systems are still prone to attacks and securing them is an important issue. To overcome this, biometric based authentication is blended with cryptography resulting in a framework called fuzzy vault which provides a high level of security. Fuzzy vault is a biometric cryptosystem used for ...

Security of a biometric system is of paramount importance considering increased commercial use for allowing access to sensitive areas. In this context protection of stored biometric templates is of particular interest as these templates are irrevocable once leaked. Fuzzy vault has emerged as a novel cryptographic construct for the protection of biometric templates. But like every other techniqu...
