Patent ID: 8683040

Claim:
An intermediary node, comprising: a first control node communication module adapted for forming a first communication network with a first control node; a second control node communication module adapted for forming a second communication network with a second control node, wherein the first communication network is communicatively separated from the second communication network; and a user node communication module adapted for forming a user communication network with at least one first user node and for receiving a user request from the first user node, wherein the intermediary node is adapted to generate an anonymous user request based on the user request and to perform a selection to transmit the anonymous user request selectively to the first control node or to the second control node, wherein the first control node communication module is adapted to receive anonymous response data from the first control node, wherein the second control node communication module is adapted to receive anonymous response data from the second control node, wherein the anonymous response data are indicative of a response to the user request, wherein the intermediary node is adapted to derive response data based on the received anonymous response data, wherein the response data comprise data to decrypt content data received previously by the first user node in an encrypted form.
