Data Sharing

Abstract

Privacy preservation in a peer-to-peer system tries to hide the association between the identity of a participant and the data that it is interested in. We propose a trust-based privacy preservation method for peer-to-peer data sharing. It adopts the trust relation between a peer and its collaborators (buddies) the buddy works as a proxy to send the request and acquire the data this provides a shield under which the identity of the requester and the accessed data cannot be merged.
