The N-methyl-D-aspartate receptor (NMDAR), a major excitatory ligand-gated ion channel in the central nervous system (CNS), is a principal mediator of synaptic plasticity. Here we report that neuropilin tolloid-like 1 (Neto1), a complement C1r/C1s, Uegf, Bmp1 (CUB) domain-containing transmembrane protein, is a novel component of the NMDAR complex critical(More)
Due to the emergence of geolocated applications, more and more mobility traces are generated on a daily basis and collected in the form of geolocated datasets. If an unauthorized entity can access this data, it can used it to infer personal information about the individuals whose movements are contained within these datasets, such as learning their home and(More)
—With the advent of GPS-equipped devices, a massive amount of location data is being collected, raising the issue of the privacy risks incurred by the individuals whose movements are recorded. In this work, we focus on a specific inference attack called the de-anonymization attack, by which an adversary tries to infer the identity of a particular individual(More)
—A geolocalised system generally belongs to an individual and as such knowing its location reveals the location of its owner, which is a direct threat against his privacy. To protect the privacy of users, a sanitization process, which adds uncertainty to the data and removes some sensible information, can be performed but at the cost of a decrease of(More)
I. MOBILITY MARKOV CHAINS In [1], we defined a type of mobility model that we coined as mobility Markov chain (MMC), which can represent in a compact yet precise way the mobility behaviour of an individual. In short, a MMC is a probabilistic automaton in which states represent points of interest (POIs) of an individual and transitions between states(More)
—To improve the transport efficiency and to reduce the traveller stress, we introduce a recommender system for bush taxis in Ivory Coast whose main objective is to propose to pedestrians potential means of transportation in their neighborhood whose destination match their own destination. The prediction of the next location relies on a mobility model called(More)
—GEPETO (for GEoPrivacy-Enhancing TOolkit) is a flexible software that can be used to visualize, sanitize, perform inference attacks and measure the utility of a particular geolocated dataset. The main objective of GEPETO is to enable a data curator (e.g., a company, a governmental agency or a data protection authority) to design, tune, experiment and(More)
Clustering is an unsupervised learning technique used to group a set of elements into non-overlapping clusters based on some predefined dissimilarity function. In our context, we rely on clustering algorithms to extract points of interest in human mobility as an inference attack for quantifying the impact of the privacy breach. Thus, we focus on the input(More)
