Secure Device Authentication Mechanisms for the Smart Grid-Enabled Home Area Networks

Erman Ayday

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 ...

Can 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 ...

Session variability modelling for face authentication

Sébastien Marcel, Laurent El Shafey

This study examines session variability modelling for face authentication using Gaussian mixture models. Session variability modelling aims to explicitly model and suppress detrimental within-class (inter-session) variation. The authors examine two techniq ...

Secure 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 ...

Cross-pollination of normalisation techniques from speaker to face authentication using Gaussian mixture models

Sébastien Marcel

This paper applies score and feature normalization techniques to parts-based Gaussian mixture model (GMM) face authentication. In particular, we propose to utilize techniques that are well established in state-of-the-art speaker authentication, and apply t ...

Unconditionally-Secure Robust Secret Sharing with Compact Shares

Alfonso Bolívar Cevallos Manzano

We consider the problem of reconstructing a shared secret in the presence of faulty shares, with unconditional security. We require that any t shares give no information on the shared secret, and reconstruction is possible even if up to t out of the n shar ...
