Abstract: Content broadcasting is an effective method of delivering content to a large number of users. Although IPbased broadcasting services are available on the Internet, their services require a broadcasting server with huge resources, which makes them unsuitable for personal broadcast applications. An obvious alternative is to deliver personal broadcasting services over a peer-to-peer network. Several products are now available to support live broadcasting in such networks. However, live broadcasting in a peer-to-peer network involves a heavy concentrated communication load and incurs network delays that result in users not necessarily viewing a live transmission simultaneously. In this paper we consider an alternative type of peer-to-peer broadcasting scheme, offline broadcasting, which provides a decentralized broadcasting service with anonymity. While offline broadcasting cannot be used for live broadcast streaming, it can be used to guarantee simultaneous viewing of predistributed con tent. We demonstrate that this scheme provides a practical alternative to existing techniques for broadcasting content that can be created in advance, and present security analysis of the scheme. (More)
