ABSTRACT:
Encrypted communications ensure privacy of communications point-to-point in a network of interactive video stations interconnected by a broadcast network. The encryption as a function of personal identity keys uniquely assigned to each station protects private communications both incoming and outgoing. Thus, a central facility having the only directory of the personal identity keys intercepts encrypted communications for reformatting and encrypting to redirect to a designated target station in the network. The keys are thus secured, and the broadcast communications are not readily analyzed for deriving sensitive data, or the communicating parties. In this manner financial transactions such as electronic payment from banks authorized in private communications with vendor stations are subject to intrusion and/or fraud.
