    Mobility data are of fundamental importance for understanding the patterns of human movements, developing analytical services and modeling human dynamics. Unfortunately, mobility data also contain individual sensitive information, making it necessary an accurate privacy...

    In a previous work, we introduced an input/output variant of stochastic automata (IOSA) that, once the model is closed (i.e., all synchronizations are resolved), the resulting automaton is fully stochastic, that is, it does not contain non-deterministic choices. However...

    Homomorphic Encryption provides one of the most promising means to delegate computation to the cloud while retaining data confidentiality. We present a plaintext recovery attack against fully homomorphic schemes which have a polynomial time distinguisher for a given fix...

    In this paper, we present a deep learning architecture which addresses the problem of 3D semantic segmentation of unstructured point clouds (Fig. 1). Compared to previous work, we introduce grouping techniques which define point neighborhoods in the initial world space ...

    International audience; We study protocols that rely on a public ledger infrastructure, concentrating on protocols for zero-knowledge contingent payment, whose security properties combine diverse notions of fairness and privacy. We argue that rigorous models are require...

    Query containment is a fundamental problem in database research, which is relevant for many tasks such as query optimisation, view maintenance and query rewriting. For example, recent SPARQL engines built on Big Data frameworks that precompute solutions to frequently re...

    In this work we analyze the security of cubic cryptographic constructions with respect to rank weakness. We detail how to extend the big field idea from quadratic to cubic, and show that the same rank defect occurs. We extend the min-rank problem and propose an algorith...
