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...

A biometric is a distinct biological trait that can be used to recognize a person. Fingerprints have been used for over a century and are the most widely used for user identification. Fingerprint identification is commonly employed in Forensic science to support criminal investigations and in biometric systems such as civilian and commercial identification devices.Fingerprint is the pattern of ...

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 ...

On Estimating Performance Indices for Biometric Identification Jay Bhatnagar, Ajay Kumar Biometrics Research Laboratory Department of Electrical Engineering, Indian Institute of Technology Delhi Hauz Khas, New Delhi 110 016, INDIA Abstract This paper investigates an information theoretic approach for formulating performance in...

Biometric Hash algorithms, also called BioHash, are mainly designed to ensure template protection to its biometric raw data. To assure reproducibility, BioHash algorithms provide a certain level of robustness against input variability to ensure high reproduction rates by compensating for intra-class variation of the biometric raw data. This concept can be a potential vulnerability. In this pape...

Multi-biometric system stores multiple templates for the same user corresponding to the different biometric sources. Infallible security should be provided to the stored biometric templates as biometric is not revocable. In this work, multi-modal biometric template security for palmprint and fingerprint is proposed which is based on the fuzzy vault generation. At first, the preprocessing steps ...

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...

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...
