Securing Online Reputation Systems through Dempster-Shafer Theory based Trust Model
|Name||Securing Online Reputation Systems through Dempster-Shafer Theory based Trust Model|
With the rapid development of online reputation systems, manipulations against such systems are evolving quickly. In this paper, we propose a Dempster-Shafer theory based trust scheme to protect reputation systems. When tested against real user attack data collected from a cyber competition, the proposed scheme has achieved a very good performance in terms of accurately identifying malicious users. It also demonstrates a great potential to effectively remove dishonest ratings and keep the online reputation system a secure and fair marketplace.
