What information is available in biometric features besides that needed for the biometric recognition process? What if a biometric feature contains Personally Identifiable Information? Will the whole biometric system become a threat to privacy? This paper is an attempt to quantifiy the link between biometrics and privacy. For a number of biometric-personal(ity) combinations, the availability, d...

Biometric systems allow automatic person recognition based on physical or behavioral features which belong to a certain person. Each biometric feature has its limits and no biometric system is perfect so unimodal biometric systems raise a variety of problems. To over fulfilling some of the mentioned inconvenient and limitations and to increase the level of security the multimodal biometric syst...

This paper focuses on a biometric signature based system as a novel tool for enhancing security in networks. The novel authentication approach takes into consideration a standardized database for analysis. Biometric perception is considered to be the most neoteric technology for sustaining security in various systems by involving exclusive identification features. The attainment of biometric pe...

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 ...

The problem of mixing, swapping and abduction is a very serious and challenging issue throughout the world. Traditional methods of biometric and non biometric techniques have their own limitations and fail to provide required level of security for newborn. A multimodal biometric system integrates information from multiple biometric sources to compensate for the limitations in performance of eac...

Biometrics is the science of measuring physical and/or behavioral characteristics that are unique to each individual and they verify that an individual is who he or she claims to be. I have discussed about various biometric characteristics. Then I discussed the basic technique and operation that every biometric system follows. This paper explains the various biometric methodologies with their c...

This technical report describes a method for biometric identification based user authentication in distributed environments, which makes use of Trusted Platforms combined with Smart Cards and Trusted Biometric Readers for providing a trusted biometric system. With this authentication method, a user can establish a trust relationship with a Biometric Reader (via integrity checking), and the user...
