Abstract
Registered peers to a P2P service can share and exchange information with other peers without servers using P2P network. In such P2P networks, there are frequent leaks of the internal privacy data of an organization through P2P file sharing. Today, DLP which is a privacy data leakage prevention technology is applied P2P network blocking and file encryption methods. However restricting all the services and normal users is difficult due to the number of ports used by P2P including the port 80. Thus, we propose a privacy data leakage prevention method by releasing a P2P sharing file that does not include privacy data using a privacy data removing technology with a privacy data leaking risk factor. The proposed method provides higher security and performance compared with a DLP method as privacy data is removed from a P2P sharing file.
