Goals

Distributed computing environments are represented by mobile ad-hoc networks, peer-to-peer networks, online social networks and so forth. Actors behind those environments are directly or indirectly human. Trust is a crucial factor for meaningful interactions and communications in such environments. Information sharing over distributed computing environments (e.g. in cloud computing), either representing overall statistical features or in fine grained details, presents an interesting challenges. One of these challenges is privacy: how do we share information respecting individual privacy yet aiming for reasonably accurate representations of the data? Interesting to explore is how both privacy-oriented and trust-oriented approaches together can bring potential solutions to the problem of information sharing. There remain open questions: how robust existing trust models and privacy preserving schemes are, how they cope with attacks, or how accurately they capture human characteristics and dynamics of trust. Peer-to-peer and mobile ad-hoc networks bring complexities such as transient relationships, re-usable identities, limited network capabilities and ad-hoc connectivities. Online social networks present issues of trust and truthfulness of representation, amongst others. Furthermore, in any decentralised environment with human actors involved there are research challenges arising from sociological as well as human-computer interaction perspectives. These complexities call for investigation of novel protocols for content sharing, user interactions, and so on.

This workshop seeks to explore the issues of trust, rating, privacy, reputation, filtering and so forth as means of establishing and re-enforcing trusted, privacy-preserving reliable information exchange in decentralised computing environments as well as relevant trust models and models for privacy integrating issues from computational theory to sociological implications, from systems implementation to usability. This workshop aims to:
  • enable the sharing of current understandings and new findings
  • facilitate the exchange of ideas and concepts arising from different approaches, thus informing each other and identifying new possibilities and problems
  • provide means for discussing alternative approaches and for researchers to form new contacts
