Physical activity recognition via minimal in-shoes force sensor configuration

Kamiar Aminian, Arash Arami, Fabien Massé, Christopher Moufawad El Achkar

We propose a new minimal wearable system and a classifier for physical activity recognition. The configuration is solely based on two force sensors placed anteriorly and posteriorly under the feet. To find the optimal sensor configuration, we estimated the ...

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 ...

LBP-TOP based countermeasure against face spoofing attacks

Sébastien Marcel, André Anjos, Tiago De Freitas Pereira

User authentication is an important step to protect information and in this eld 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 to ...

Selection and Combination of Local Gabor Classiﬁers for Robust Face Veriﬁcation

Hazim Kemal Ekenel, Nuri Murat Arar, Hua Gao

Gabor features have been extensively used for facial image analysis due to their powerful representation capabilities. This paper focuses on selecting and combining multiple Gabor classiﬁers that are trained on, for example, different scales and local regi ...

Establishing Trusted Identities

Rafik Chaabouni

Many online transactions require the sharing of identity information, even though this sharing poses substantial trust challenges, both for the sender and the receiver. For this reason, Internet must provide channels to ensure a secure, reliable, private, ...

Deniable RSA Signature: The Raise and Fall of Ali Baba

Serge Vaudenay

The 40 thieves realize that the fortune in their cave is vanishing. A rumor says that Ali Baba has been granted access (in the form of a certificate) to the cave but they need evidence to get justice from the Caliph. On the other hand, Ali Baba wants to be ...

Inter-session Variability Modelling and Joint Factor Analysis for Face Authentication

Sébastien Marcel

This paper applies inter-session variability modelling and joint factor analysis to face authentication using Gaussian Mixture Models. These techniques, originally developed for speaker authentication, aim to explicitly model and remove detrimental within- ...

The Failure Detector Abstraction

Rachid Guerraoui

A failure detector is a fundamental abstraction in distributed computing. This paper surveys this abstraction through two dimensions. First we study failure detectors as building blocks to simplify the design of reliable distributed algorithms. In particul ...

Rgtsp: a generalized top scoring pairs package for class prediction

Mauro Delorenzi, Vlad Popovici

A top scoring pair (TSP) classifier consists of a pair of variables whose relative ordering can be used for accurately predicting the class label of a sample. This classification rule has the advantage of being easily interpretable and more robust against ...
