Bi-Modal Biometric Authentication on Mobile Phones in Challenging Conditions
Sébastien Marcel, Laurent El Shafey
This paper examines the issue of face, speaker and bi-modal authentication in mobile environments when there is significant condition mismatch. We introduce this mismatch by enrolling client models on high quality biometric samples obtained on a laptop com ...
2014Anti-Spoofing: Face Databases
Sébastien Marcel, André Anjos, Ivana Chingovska
Datasets for the evaluation of face verification system vulnerabilities to spoofing attacks and for the evaluation of face spoofing countermeasures. ...
Springer US2014Face Anti-spoofing: Visual Approach
User authentication is an important step to protect information and in this regard face biometrics is advantageous. Face biometrics is natural, easy to use and less human-invasive. Unfortunately, recent work revealed that face biometrics is quite vulnerabl ...
Springer-Verlag2014Misuse-Resistant Variants of the OMD Authenticated Encryption Mode
Serge Vaudenay, Damian Vizár, Reza Reyhanitabar
We present two variants of OMD which are robust against nonce misuse. Security of OMD---a CAESAR candidate---relies on the assumption that implementations always ensure correct use of nonce (a.k.a. message number); namely that, the nonce never gets repeate ...
Springer-Verlag Berlin2014OMD: A Compression Function Mode of Operation for Authenticated Encryption
Serge Vaudenay, Damian Vizár, Reza Reyhanitabar
We propose the Offset Merkle-Damgård (OMD) scheme, a mode of operation to use a compression function for building a nonce-based authenticated encryption with associated data. In OMD, the parts responsible for privacy and authenticity are tightly coupled to ...
Springer International Publishing2014Secure Computing with the MPEG RVC Framework
Marco Mattavelli, Richard Thavot, Junaid Jameel Ahmad
Recently, ISO/IEC standardized a dataflow-programming framework called Reconfigurable Video Coding (RVC) for the specification of video codecs. The RVC framework aims at providing the specification of a system at a high abstraction level so that the functi ...
Elsevier Science Bv2013Can face anti-spoofing countermeasures work in a real world scenario?
Sébastien Marcel, André Anjos, Tiago De Freitas Pereira
User authentication is an important step to protect in- formation and in this field face biometrics is advantageous. Face biometrics is natural, easy to use and less human-invasive. Unfortunately, recent work has revealed that face biometrics is vulnerable ...
2013Secure Device Authentication Mechanisms for the Smart Grid-Enabled Home Area Networks
In this paper, we propose secure and intuitive device authentication techniques for the Smart Grid enabled Home Area Networks (HANs). We assume a distributed architecture for the HAN in which the smart appliances can communicate both with the smart meter a ...
2013On Selecting the Nonce Length in Distance-Bounding Protocols
Serge Vaudenay, Christos Dimitrakakis, Aikaterini Mitrokotsa
Distance-bounding protocols form a family of challenge-response authentication protocols that have been introduced to thwart relay attacks. They enable a verifier to authenticate and to establish an upper bound on the physical distance to an untrusted prov ...
