Abstract

The following explains a method to enable the sender of information to have control over the access of the received information. Since a sender would know the sensitivity of the data better than the receiver, it is a more natural choice as a controller of the access of that data. This is an improvement over relying upon addresses and signaIling in the data receiver to make a decision upon data sensitivity. This is because all data that could arrive on the same address could have varying levels of sensitivity. Encrypting the transmission of a message is usually used to protect sensitive information but since a data receiver will usually decrypt the message before it is displayed, other levels of security must be implemented. Thus the use of message headers speciiically to control the access of information can effectively be applied to protect received messages.
