"In response to the lack of user anonymity and long-term data persistence in existing P2P systems, we developed the Graffiti Network distributed file sharing protocol that uses multiple third-party storage sites as a data replication and transfer medium between clients. Our approach is to use publically available web sites to store multiple copies of shared content. We use the term graffiti for our work since we are storing data in a way that non-network participants may regard as unsightly or unwanted vandalism." Less
