SocialTrust: Tamper-Resilient Trust Establishment in Online Communities

Web 2.0 promises rich opportunities for information sharing, electronic commerce, and new modes of social interaction, all centered around the "Social Web" of user-contributed content, social annotations, and person-to-person social connections. But the increasing reliance on this "Social Web" also places individuals and their computer systems at risk, creating opportunities for malicious participants to exploit the tight social fabric of these networks. With these problems in mind, the authors propose the SocialTrust framework for tamper resilient trust establishment in online communities.
