In order to ensure privacy constraints in biometrics, new algorithms called template protection schemes have been proposed in the last ten years in the literature. Most of these algorithms require as input a feature having a fixed size. Texture features can be used within this context for fingerprints as the number of minutiae varies in general for...

We address in this paper the problem of privacy in fingerprint biometric systems. Today, cancelable techniques have been proposed to deal with this issue. Ideally, such transforms are one-way. However, even if they are with provable security, they remain vulnerable when the user-specific key that achieves cancelability property is stolen. The promi...

The storage of fingerprints is an important issue as this biometric modality is more and more deployed for real applications. Considering minutiae templates as sensitive information, a key question concerns the secure and privacy management of this digital identity. Indeed, if an attacker obtains the minutiae template of a subject, he/she will be a...

BioHashing is a popular biometric template protection scheme defined in the last decade. Most of previous studies on this algorithm focus on the performance optimization or the use of this privacy protection scheme on many types of biometric modalities (face, fingerprint, palmprint...). The objective of this paper is to study the robustness of this...

We address in this paper the problem of privacy in the current architecture in electronic passports for the storage and transmission of biometric data such as fingerprints. The current architecture provides a good protection of biometric personal data but brute force attack could be used in a near future using cloud computing. We propose a new solut...

With more and more applications using biometrics, new privacy and security risks arise. Some new biometric systems have been proposed in the last decade following a privacy by design approach: cancelable biometric systems. Their evaluation is still an open issue in research. The objective of this paper is first to define an evaluation methodology f...

The Internet has consolidated itself as a very powerful platform that has changed the communication and business way. Nowadays, the number of users navigating through Internet is about 1,552 millions according to Internet World Stats. This large audience demands online commerce, e-government, knowledge sharing, social networks, online gaming . . ....

Biometrics is an emerging technology for user authentication. However, biometric data is generally non-revocable unlike a password (as it is not possible to change it). To overcome this problem, biometric template protection schemes have been proposed in the last decade. The purpose of this paper is to study the robustness of a popular algorithm ca...

The storage of fingerprints is an important issue as this biometric modality is more and more deployed for real applications. The a prori impossibility to revoke a biometric template (like a password) in case of theft, is a major concern for privacy reasons. We propose in this paper a new method to secure fingerprint minutiae templates by storing a...

La biométrie est une solution émergente pour la vérification d'identité d'un individu lors des applications de contrôle d'accès physique et logique. Même si cette technologie se révèle prometteuse (forte relation entre l'individu et son authentifiant), il reste encore des problèmes importants à résoudre. Le premier concerne le respect de la vie pri...

The challenges during the deployment of biometric systems are numerous. We have to take into account performance, privacy, security and acceptability issues. In this context, we developed an authentication system using fingerprints whose extraction phase of the representative model breaks up into two stages. In the first stage, a vector characteris...

Because biometrics-based authentication offers several advantages face to other authentication methods, it is important that such systems be designed to withstand attacks. Reliability and privacy for the public acceptance of the system are also important factors. BioHashing is presented as a new technique to moderate the impact of susceptible threa...

Minutiae correspond essentially to the termination and bifurcation of fingerprint patterns. Since the quality of fingerprint images is often low, extraction algorithms produce a large number of false alarms. A complete minutiae extraction scheme for automatic fingerprint recognition systems is presented. A great deal of work has been dedicated to f...
