Construct a novel reputation-based trust model for P2P E-commerce

To establish trust among strange peers for P2P e-commerce, this paper proposes a novel reputation-based trust model. Trust evaluation consists of local reputation and global reputation, which are introduced comprehensive trust factors and made the computing methods better. Especially, by introducing the blacklist mechanism, malicious peers, when are detected, will be dragged into blacklist, so that other peers will never interact with them to benefit to set up a trust transaction environment. The experiment results demonstrate that the proposed model can measure trust and separate malicious peers for P2P e-commerce effectively.
