System and Method For Securely Communicating On-Demand Content From Closed Network to Dedicated Devices, and For Compiling Content Usage Data in Closed Network Securely Communicating Content to Dedicated Devices

摘要

A system for securely communicating content as streaming data is provided. The system includes a closed network created on a public network, and a dedicated device for receiving twice-encrypted streamed content from the closed network. Upon authentication of the dedicated device, a content enabling component in the closed network twice-encrypts previously once-encrypted streamed content by using randomly selected encryption algorithms, and streams the twice-encrypted streamed content to the dedicated device during a closed network communication session and through a closed connection established between the closed network and the dedicated device. The dedicated device includes a content enabling component having a unique content enabling component identifier and a unique decryption key. The dedicated device decrypts the twice-encrypted streamed content by using its unique information and decryption key as well as randomly selected information received from the closed network during the closed network communication session and through the closed connection.
