Opportunities and Challenges in Securely Reusing and Repurposing Mobile Devices
Adelin Roty, Jan Tobias Mühlberg, Jean-François Determe
An estimated 5.3 billion mobile phones became electronic waste in 2022. Many of these devices can be repurposed and used in different contexts to extend their lifetime and to reduc…
Monitoring Large Crowds With WiFi: A Privacy-Preserving Approach
Jean-François Determe, Sophia Azzagnuni, Utkarsh Singh +2
This paper presents a crowd monitoring system based on the passive detection of probe requests. The system meets strict privacy requirements and is suited to monitoring events or b…
MAC Address Anonymization for Crowd Counting
Jean-François Determe, Sophia Azzagnuni, François Horlin +1
Research has shown that counting WiFi packets called probe requests (PRs) implicitly provides a proxy for the number of people in an area. In this paper, we discuss a crowd countin…
Improving the Correlation Lower Bound for Simultaneous Orthogonal Matching Pursuit
Jean-François Determe, Jérôme Louveaux, Laurent Jacques +1
The simultaneous orthogonal matching pursuit (SOMP) algorithm aims to find the joint support of a set of sparse signals acquired under a multiple measurement vector model. Critical…
On the Noise Robustness of Simultaneous Orthogonal Matching Pursuit
Jean-François Determe, Jérôme Louveaux, Laurent Jacques +1
In this paper, the joint support recovery of several sparse signals whose supports present similarities is examined. Each sparse signal is acquired using the same noisy linear meas…
On The Exact Recovery Condition of Simultaneous Orthogonal Matching Pursuit
Jean-François Determe, Jérôme Louveaux, Laurent Jacques +1
Several exact recovery criteria (ERC) ensuring that orthogonal matching pursuit (OMP) identifies the correct support of sparse signals have been developed in the last few years. Th…
