Study of Filter Sharing Method Using Virtual Peers in P2P Networks

Among the problems faced by peer-to-peer (P2P) networks is the malicious content that often spreads unchecked because such contents are transferred from any peer to the other peer directly. While various personal and/or shared countermeasure filtering methods are available, such filters have different configurations and strength levels. Therefore, if malicious content is permitted to penetrate peers with weak filters, they can spread across an entire network. In response, in this paper, we propose a filter sharing method that utilizes virtual peers.
