  • Patent number: 8302204
    Abstract: A method and a system for a secure distributed item-level discovery service using secret sharing. The discovery service publishes a plurality of uniform resource locators that correspond to a resource identification key on a plurality of servers in a P2P ring. A uniform resource locator (URL) is split in a plurality of shares applying a secret sharing algorithm. For each share of the URL is generated share identifier by applying a hash function to the resource identification key. A share identifier is sent to a target node through a first proxy node applying Peer-to-Peer (P2P) routing. A share of the URL, corresponding to the share identifier is sent to the target node through a second proxy using a network address of the target node. Access rights for reading the share of the URL from the target node are published in an access control node.
