Spam Harassment Reduction via Economic Disincentives
Thursday, April 15, 2004Balachander KRISHNAMURTHY (AT&T Labs)
Unsolicited commercial electronic mail, commonly referred to as spam, has continued to wreak havoc with electronic communication. Such email consumes significant bandwidth, users' productivity, and disk space. Several solutions have been proposed to eliminate spam in the last few years. We broaden the definition of spam as any email unwanted by the intended recipient. We propose a novel scalable scheme that aims to add monetary cost to senders of such unwanted mail while allowing legitimate mail to be exchanged at no cost to users and in the same manner as today. Our scheme is entirely complementary to the large number of receiver-based filtering ideas in use today. We describe our scheme, describe how it can be integrated into the existing Internet email infrastructure, and discuss our prototype implementation. Our scheme will neither outlaw spam, nor make it obsolete; however it will add monetary cost only to spammers thereby increasing the potential of lowering the frequency and amount of spam.
