  • Patent number: 8756658
    Abstract: A requester node requesting a service in a peer-to-peer network transmits a request to a service provider node. The request may include a communication history of the requester node identifying other nodes with which the requester node has previously communicated. The service provider node authenticates the requester node based on the communication history. The service provider node may ask other nodes with which the requester node has communicated for evaluation of the requester node. The other nodes may calculate a trust metric of the requester node and provide this metric to the service provider node. The service provider node may use this trust metric in combination with a similarity calculation of the requester node and the service provider node to make a determination whether the requester node is to be authenticated. The service provider node may evaluate the requester node and store the evaluation in its communication history.

  • Patent number: 8589684
    Abstract: A communication device, method and network are provided. The communication method comprises generating a first registration packet including first bio data, sending the first registration packet to a network, generating a content packet having second bio data and content data and sending the content packet to the network. The other communication method comprises receiving a first registration packet including first bio data, storing the first bio data together with a device identification, receiving a content packet including second bio data, extracting the second bio data from the content packet, comparing the first bio data with the second bio data and authorizing communication when the first bio data matches the second bio data.

  • Patent number: 8521714
    Abstract: Technologies are generally described for a peer to peer search routing algorithm and system. In one example, a node in a peer to peer network includes a processor. In some examples, the processor may be configured to receive information regarding a topology of the peer to peer network and generate a first search routing algorithm for the peer to peer network based on the topology. In some examples, the processor may be configured to generate a second search routing algorithm for the peer to peer network based on a search characteristic and the topology. In some examples, the second search routing algorithm is distinct from the first search routing algorithm. In some examples, the processor may be configured to receive a request to search the peer to peer network. In some examples, the processor may be configured to search the peer to peer network using the second search routing algorithm.
