Abstract: A method and system for electronically delivering files over a public network is disclosed. The network includes a plurality of computers including at least one server node and multiple client nodes. In a first aspect of the present invention, the method and system enable secure and reliable peer-to-peer file sharing between two client nodes. First, a digital fingerprint is generated and associated with a file in response to the file being selected for publication on a first client node. An entry for the file is then added to a searchable index of shared files on the server node, and the fingerprint for the file is also stored on the server. In response to a second client selecting the file from the search list on the server node, the file is automatically transferred from the first client node directly to the second client node.

Abstract: A method and system for providing a digital file marketplace is disclosed. The method and system include allowing content owners to share their digital files on the marketplace for access by consumers, and generating revenue by charging the consumers fees for receiving or opening the digital files. The method and system further include paying a percentage of the revenue to the content owners as royalties. In a further aspect of the present invention, consumers may become affiliates of the marketplace where the unused bandwidth of the consumer's computers is used to deliver the files to other consumers. As an incentive, affiliates are also paid for donating the bandwidth and for referring new consumers to the marketplace.

Abstract: A method and system for generating revenue in a peer-to-peer file delivery network that includes at least one server node and multiple client nodes is disclosed. The method and system include enabling peer-to-peer file sharing of content by initiating, on one client node, a download of a particular content item served from the server node or another client node, and then charging a fee based on a quantity of the content served. The method and system further include enabling decentralized downloads of subscription-based content. The decentralized downloads are provided by allowing the client nodes to subscribe to one or more of the subscription-based content, periodically sending the subscribed to subscriptionbased content to each the respective subscribing client nodes, and charging a fee to providers of the subscription-based content for serving the subscription-based content.
