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...

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 ...

O n the basis of media hype alone, you might conclude that biometric passwords will soon replace their alphanumeric counterparts with versions that cannot be stolen, forgotten , lost, or given to another person. But what if the performance estimates of these systems are far more impressive than their actual performance? To measure the real-life performance of biometric systems—and to understand...

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...

Every colleges, offices, banks and industry are using biometric recognition system for authentication of employers. This biometric authentication system are use biometric templates or characteristics of employer and based on comparison of this template with enrolled data or template of employer for making decision about allowed enter into organization or not. So protection and recognition of hu...

Recently, biometric market is growing rapidly and biometric applications can be found in diverse areas such as border control, banking, ID-documents, access control, etc. However, usage of personal biometric information can harm privacy of users and raise problems of cross matching and identity theft. Privacy preserving techniques like template protection are an important supplement to biometri...

Biometric recognition systems use measures from the body itself to determine the identity of an individual. The electrocardiogram (ECG) has been increasingly used as a biometric measure for person identification, as it is an easily measurable characteristic of all individuals. Our method for ECG acquisition follows an off-the-person approach, using a single ECG lead with non-gelled electrodes p...
