Abstract

The present invention provides methods and system for encrypting and transmitting data to a recipient (16). More particularly, the method of the invention allows encrypting selected portions of data stream that is sent to a recipient (16) authorized to decrypt the encrypted portions via a third party intermediary (14) who is not authorized to decrypt the encrypted portions.
