The defense mechanism of online reputation systems. Presented at Discover URECA @ NTU poster exhibition and competition, Nanyang Technological University, Singapore. | Abstract: | Online reputation systems are virtual networks in which individuals share opinions by providing ratings to products, people and so on. However, manipulation of such systems is rapidly growing. One typical and popular attack is collaborative unfair rating in such systems. Our work is to investigate and propose the defense mechanism that detects collusive unfair raters based on similarity in their rating behaviors.
