Abstract
A method and apparatus for providing protection from unauthorized use of messages received by a system is described. The receiving system can receive a message from a sending system, for example, over a network or from local media. The message can be an e-mail message, the contents of a Web page, music, or software, etc. The receiving system stores the digital information in a storage device in a manner designed to conceal the message from unauthorized access. When a user of the receiving system wants to view the message, the digital information is accessed, the message is generated from the digital information and displayed at the receiving system. Use of this generated message is restricted. In another embodiment, this use is limited to outputting (i.e., displaying and producing sound) the generated message at the receiving system. The receiving system cannot copy, modify, save, forward, or capture any portion of the generated message. In another embodiment, restrictions on the use of the generated message are relaxed to allow printing a copy of the generated message.
