A method is presented for processing data for a privacy policy concerning management of personally identifiable information. A proxy intercepts a first message from a server to a client and determines that the first message initiates collection of personally identifiable information from a user of the client. The proxy then sends a second message to the client that requests consent from the user to the privacy policy. If the user provides consent within a third message that is received by the proxy from the client, then the proxy sends the intercepted first message to the client. If the user does not provide consent, then the proxy sends a fourth message to the server that fails the collection of personally identifiable information from the client by the server. The proxy may also obtain user preferences for options concerning management of the personally identifiable information by a data processing system.
