Anti-spam email system in Facebook

Email spam is one of the most critical problems facing social networks and the Internet today. Current anti-spam solutions have common weaknesses of low accuracy and high false positive rates. In this paper, we present an anti-spam mechanism based on social reputation, to successfully block spam collaboration between network participants. Using interconnection relationships within a social network we construct a topology and convert the mail transmission problem into a routing problem based on a trust-updating mechanism with respect to users´ feedback. In addition to simulations, we have also implemented our method on the Facebook social network Through this study, we can effectively detect and filter spam E-mail messages, while promoting the development of social network applications.
