Method and system for predicting victim users and detecting fake user accounts in online social networks

摘要: A system and method for predicting victims detecting fake accounts in OSNs, comprising: a feature-based classifier by classifying, with classification probability, target variable of each user the OSN social graph; graph-transformer transforming graph into defense reassigning edge weights to incorporate victim predictions using graph-based detector users computing through power iteration probability random walk land on node after 0(log n) steps, assigning rank value equal node's landing normalized degree, sorting nodes their estimating detection threshold such that whose is smaller than flagged as representing account.
