SPA: A Secure and Private Auction Framework for Decentralized Online Social Networks
Abstract— SPA: A Secure and Private Auction Framework for Decentralized Online Social Networks. The security and privacy threats on e-commerce have attracted intensive attention recently. The explosive growth of online social networks OSNs < Final Year Projects 2016 > has made them potential new great marketplaces for e-commerce, which, however, raise serious security and privacy concerns. This is mainly due to the centralized system architecture where the service provider knows all users’ private data and becomes the single point of failure. To this end, we propose a secure and private auction framework, called SPA, for decentralized online social networks (DOSNs). SPA consists of three phases: identity initiation, buyer-seller matching, and private auction.
