Method and system for implementing privacy policy enforcement with a privacy proxy

摘要

A method is presented for enforcing a privacy policy concerning management of personally identifiable information in a centralized manner through a privacy proxy agent. A proxy intercepts a message from a first system to a second system, e.g., from a server to a client, and determines whether the message is associated with an operation on personally identifiable information; if not, then the proxy sends the message to the second system, but if so, then the proxy determines whether the operation on the personally identifiable information is compliant with a privacy policy and with user preference information with respect to the privacy policy for a user who is associated the personally identifiable information. If the message is compliant with the privacy policy and user preference data, then the proxy sends the first message to the second system; otherwise, an error indication is returned to the first system.
