Spam Filtering

Terri Oda

Abstract.

Spam, the electronic equivalent of junk mail, affects over 600 million users worldwide. Even as anti-spam solutions change to limit the amount of spam sent to users, the senders adapt to make sure their messages are seen. My presentation looks at my work on application of the artificial immune system model to protect email users from spam. The resulting system classifies the messages with similar accuracy to other spam filters, but uses a fairly small number of detectors to do so, making it an attractive solution for circumstances where processing time is at a premium. In particular, I will describe tests the spam immune system against the publicly available SpamAssassin corpus of spam and non-spam.
