Appl. No.:

10/134184

Inventors:

William G. Barrus - Apex NC, US
Cary L. Bates - Rochester MN, US
Robert J. Crenshaw - Apex NC, US
Paul R. Day - Rochester MN, US

Assignee:

International Business Machines Corporation - Armonk NY

International Classification:

H04L 9/12

US Classification:

713170, 713168, 713169, 726 2, 726 3, 726 4, 726 5, 726 6

Abstract:

A secure messaging system and method. The method can include the steps of receiving an encrypted message, the message having been encrypted using a token of a corresponding pervasive device; wirelessly verifying the presence of the pervasive device; and, if the presence can be verified, decrypting the message using the token. The verification step can include the steps of establishing a wireless link with the pervasive device; and, querying the pervasive device over the wireless link. In particular, the establishing step can include the step of establishing a Bluetooth link with the pervasive device. Furthermore, the querying step can include the step of requesting geographic coordinates which locate the pervasive device.

US Classification:

709207000

Abstract:

A method, system and apparatus for cooperative spam control. A cooperative spam control method can include the step of accepting an electronic spam notification received from a peer e-mail recipient in a common computing group identifying a spam message received by the peer e-mail recipient. The method further can include the step of storing the notification. Finally, if an e-mail is subsequently received which corresponds to the identified spam message, the received e-mail can be processed as spam. In a preferred aspect of the invention, the method also can include the steps of determining that a received e-mail is spam; and, communicating an electronic spam notification identifying the received e-mail determined to be spam to other peer e-mail recipients in the common computing group.
