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...
We study in this work the potential side channel leakages of a hardware biometric comparison system that has been designed for fingerprints. An embedded biometric system for comparison aims at comparing a stored biometric data with a freshly acquired one without the need to send the stored biometric data outside the system. Here one may try to retrieve the stored data via side channel, similarl...
Soft biometric traits like gender, age, height, weight, ethnicity, and eye color cannot provide reliable user recognition because they are not distinctive and permanent. However, such ancillary information can complement the identity information provided by the primary biometric traits (face, fingerprint, hand-geometry, iris, etc.). This paper describes a hybrid biometric system that uses face ...
In this paper, a semi fragile watermarking scheme based on compressive sensing theory proposed for detection of spoofing or modification of biometric template. This proposed scheme is explored sparseness, incoherent and computation security provided by compressive sensing for biometric template protection. The Discrete Cosine Transform (DCT) coefficients of biometric template are used to comput...

Performances of biometric recognition systems can degrade quickly when the input biometric traits exhibit substantial variations compared to the templates collected during the enrolment stage of system’s users. On the other hand, a lot of new unlabelled biometric data, which could be exploited to adapt the system to input data variations, are made available during the system operation over the ...
In this contribution a survey is presented about the possibilities and difficulties of a cryptographic protection of biometric information for the purpose of authentication. The crucial role of sufficient information content of biometric templates will be presented. It will be shown how to use this approach of a cryptographic protection of biometric templates in connection with biometric databa...
