The purpose of the e-mail is to publish in a public forum a method of
preventing credit card fraud using Geolocation, anonymous proxy, e-mail
domain, and bank identification number databases.
The method rates possible credit card transactions on the likelihood that
they are fraudulent. It takes the following as inputs:
# Client IP Address
# Billing City/State/ZipCode/Country
# Bank Identification Number (first 4-6 numbers of credit card number)
# E-mail domain (e.g. hotmail.com, aol.com)
And outputs:
# IP Address Location
# Distance from IP address to Billing Location
# Whether e-mail is from free e-mail provider
# Whether IP address is Anonymous Proxy
# Whether IP address country matches Billing country
# Credit Card Issuing Bank Country
# Whether IP address country matches bank country
# Overall Fraud Score based on above outputs
It uses a database of IP address to city mappings, a database of free
e-mail domains, a database of bank identification number locations, and a
database of anonymous proxies.

P.S. The purpose of this e-mail is to release this idea into the public
domain, provide prior art, and to protect anybody who implements this
service from patent infringement suits. In other words, an "Anti-Patent".
