Patent ID: 8850200

Claim:
A system for secure exchange of data intermediated by a trusted server interposed between a sender device and a receiver device on a packet-based network, comprising: a trusted intermediary server configured to interface with a sender device and a receiver device over a packet-based network to intermediate transmissions between the sender and the receiver over the packet-based network as a first communication path; wherein said trusted intermediary server is configured for interfacing with application programming executing at the sender device and at the receiver device for establishing the first communication path from the sender device to said trusted intermediary server to the receiver device; wherein said trusted intermediary server must be used in combination with a security key communicated between the sender device and the receiver device over a second communication path without being intermediated by said trusted intermediary server; said trusted intermediary server configured to receive a first transmission initiated by said sender device, to verify authenticity of said sender device, to initiate a second transmission to said receiver device, and to verify authenticity of the receiver device; said trusted intermediary server configured to operably retain a linkage between the sender device and the receiver device and to communicate encrypted data received from application programming at the sender device to application programming at the receiver device, following verification of authenticity of both said sender device and said receiver device.
