Abstract: A privacy infrastructure platform or system provides for privacy enabling communication and secures trade of both electronic and physical goods and services. Through user-controlled communication rules, including an access control filter and a dynamic routing service, the individual is in control of communication. The system enables a universal user-controlled opt-in filter for SPAM protection. Support is provided for privacy enabling the full value chain from the original supplier to the consumer. In addition, the system supports trade across existing standard barriers, supporting standard conversion, government reporting, and existing and future eCommerce standards such as EDIFACT, OFX, OBI and CBL. Privacy is established using a principle of multiple non-linkable pseudonyms or virtual identities (VID), combined with intermediation of on- and off-line communication channels.
