Method and system for preventing computer worm dissemination using encryption

Abstract

A method and system for preventing a computer worm from unauthorized use of data indicative of at least one e-mail address stored in a data base is presented. The method comprises the steps of encrypting said data, receiving at least one e-mail message by accessing an e-mail server, decrypting said selected ones of said data to provide access thereto, and addressing at least one e-mail message using said decrypted data. The method further includes the step of re-encrypting the selected decrypted data. In one aspect of the invention, the method of encrypting the data comprises the steps of obtaining a key value, selecting each of the at least one e-mail address, encrypting the selected e-mail address using the key value; and storing said encrypted e-mail in the data base.
