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...

Iris recognition is gaining popularity as a robust and reliable biometric technology. The intricate structure of the iris constitutes a powerful biometric modality utilized by iris recognition algorithms to extract biometric templates. Proposed approaches report recognition rates above 99% and equal error rates less than 1% on diverse data sets. Providing high accuracy iris recognition appears ...

Biometric systems are developed in order to replace traditional authentication. However, protecting the stored templates is considered as one of the critical steps in designing a secure biometric system. When biometric data is compromised, unlike passwords, it can’t be revoked. One methodology for biometric template protection is ‘Biometric Cryptosystem’. Biometric cryptosystems benefit from bo...

Template protection is an issue of paramount importance for the design secure and privacy-compliant biometric recognition systems. unlinkability, together with template irreversibility, essential requirement to properly guarantee protection. In fact, it ensures that templates generated from same trait, but used in different applications, cannot be linked identity. This paper deals a system sati...

Biometric templates are often used in intelligent human computer interaction systems that include automated access control and personalization of user interaction. The effectiveness of biometric systems is directly linked with aging that causes modifications on biometric features. For example the long term performance of person identification systems decreases as biometric templates derived fro...

Biometric systems are subjected to a variety of attacks. Stored biometric template attack is very severe compared to all other attacks. Providing security to biometric templates is an important issue in building a reliable personal identification system. Multi biometric systems are more resistive towards spoof attacks compared to unibiometric counterpart. Soft biometric are ancillary informatio...

In its most general definition, Biometrics refers to the science of automatic recognition of individuals based on some specific physiological and/or behavioural features. A biometric system that is based on one single biometric identifier does not always come to meet the desired performance requirements; multimodal biometric systems come to be an emergent trend. In this paper, we discuss the mo...
