Collaborative information systems (CISs) allow groups of users to communicate and cooperate over common tasks. CIS are increasingly relied upon to manage sensitive information. In this paper, we introduce a framework to detect anomalous insiders from the access logs of a CIS by leveraging the relational nature of system users as well as the meta-information […]
Logoot-Undo: Distributed Collaborative Editing System on P2P Networks
Peer-to-peer systems provide scalable content distribution for cheap and resist to censorship attempts. However, P2P networks mainly distribute immutable content and provide poor support for highly dynamic content such as produced by collaborative systems. A new class of algorithms called CRDT (Commutative Replicated Data Type), which ensures consistency of highly dynamic content on P2P networks, […]
