Randy Atkins: SPAM is usually detected by looking at an e-mail’s content.  But Nick Feamster, of Georgia Tech, has engineered a technique that never sees messages at all…only the behavior of their senders.

Nick Feamster: We look at the traffic patterns in terms of what time of day a message might be sent, where it might be coming from, who it might be going to, and who else that sender might have talked to beside just you.

Randy Atkins: Feamster says the technology, which is already being used by some e-mail service providers, is nimble.

Nick Feamster: A computer program that needs to read an e-mail actually has to be fairly computing-intensive and fairly intelligent.  Our technique basically is just looking at very lightweight behavioral features, which means that it can be done at very high rates.

Randy Atkins: And catch more junk.  With the National Academy of Engineering, Randy Atkins, WTOP News.
