Abstract

Methods, articles, signals, and systems are provided for protecting email message contents. A self-removing message is designated as such by the message'"'"'s originator, and a self-removal enhancement such as self-removal code or self-removal indicators are added to conventional message content before the message is transmitted over a computer network toward one or more recipients. Copies of the message may be removed from intermediate network nodes by software which recognizes, and acts in response to, self-removal indicators. At the recipient'"'"'s location, the message is displayed and then removed from disk and from memory without additional effort by the recipient. Thus, the burden of removing unsolicited email messages is transferred from recipients to the system and the message'"'"'s originator. Security of messages may also be enhanced by reducing the number of copies of confidential message content and/or the accessible life span of those copies.

Claims

1. A method for using self-removing messages, comprising the steps of creating a self-removing message at an origin and then transmitting the self-removing message toward a recipient, wherein the creating step comprises including self-removing code in the message.

2. The method of claim 1, wherein the transmitting step comprises broadcasting the message toward recipients who are not personally known to the originator.

3. The method of claim 1, wherein the method comprises creating and transmitting a self-removing message having contents which include a notice.

4. The method of claim 1, wherein the method comprises creating and transmitting a self-removing message having contents which include an announcement.

5. The method of claim 1, wherein the method comprises creating and transmitting a self-removing message having contents which include a link to a web site.

6. The method of claim 1, wherein the creating step comprises including self-modifying self-removing code in the message.

7. A computer storage medium having a physical configuration which causes a computer system to operate according to a method for using self-removing messages, the method comprising the steps of creating a self-removing message at an origin and then transmitting the self-removing message toward a recipient, wherein the creating step comprises including self-removing code in the message.

8. A computer system comprising a processor and a memory, the memory having a physical configuration which causes the computer system to operate according to a method for using self-removing messages, the method comprising the steps of creating a self-removing message at an origin and then transmitting the self-removing message toward a recipient, wherein the creating step comprises including self-removing code in the message.

9. A method for using self-removing messages, comprising the steps of displaying message content which was sent in a self-removing message, and removing message content in response to a self-removal enhancement of the self-removing message, wherein the removing step searches for copies of the message content.

10. The method of claim 9, wherein the removing step displays a dummy message while searching for copies of the message content.

11. A computer storage medium having a physical configuration which causes a computer system to operate according to a method for using self-removing messages, the method comprising the steps of displaying message content which was sent in a self-removing message, and removing message content in response to a self-removal enhancement of the self-removing message, wherein the removing step searches for copies of the message content.

12. A computer system comprising a processor and a memory, the memory having a physical configuration which causes the computer system to operate according to a method for using self-removing messages, the method comprising the steps of displaying message content which was sent in a self-removing message, and removing message content in response to a self-removal enhancement of the self-removing message, wherein the removing step searches for copies of the message content.
