摘要

An object of the present invention is to provide a privacy protection query methods and privacy protection query system for use in the Federation of type Union network. In A at least one embodiment, for example, comprise a node having information corresponding to the information request is delivered to the federation type federated network potentially, the node, at least one information request receiving a packet, performing a search for information in that node, to determine whether information required is present, if the information requested is present, then the node is the requesting node an acknowledgment linear network information to be transmitted, request, m is the k least the number of packets that need to be received by the requesting node to reconstruct the requested information, to the m packets - coding, any third parties, so as not to see the packets that exceed the different k-1 one selects a plurality of paths between that node and the requesting node, the m-number of packets, dispersed in their chosen path for transmission. In a further embodiment, the system and method includes an operation of the network to have the ability to provide the corresponding information in a protected manner.FIELD 1
