摘要：Online communities are the new-age platform for sharing information and experiences with groups of people. Members of a community are dealing with the daily con.ict of having to de- cide what information they are willing to disclose in order to increase their reputation. Fear of possible privacy loss may lead a member to avoid sharing information with others, even when act- ing anonymously. Privacy concerns are amplified when users are members of multiple communities and their overall reputation is obtained from their reputation in each community. Disclosing a piece of reputation-related information in one community may cause privacy loss in another community and vice versa. This paper outlines the privacy concerns in the Cross-Community Reputation (CCR) model for sharing reputation knowledge across communities. These privacy concerns are discussed and modeled, and a policy-based approach that copes with them is presented
