Abstract

Spam faxing has become a problem in the industry. People troll through telephone numbers until they get a fax number and then sell the aggregation of numbers to spam advertisers. These advertisers then fax large numbers of advertisements to their fax directory. They are using the machines and supplies of the recipients of their advertising without permission. Clearly this is a problem. One way of solving this problem would be to simply turn the fax machine off when it is not in use, but this is not terribly practical. Some businesses may have different groups in different locations faxing information back and forth at all times of day. What is needed is a means of determining if the sender of a fax is authorized to send the fax before valuable resources are spent printing it out. A TCPA compliant fax system could solve this problem. This Mechanism is illustrated in the Figure below. A TCPA Trusted Platform Module (TPM) chip is added to a Group III Fax machine to make it TCPA compliant. Faxes sent by such a Fax machine to another TCPA compliant Fax machine would use the Public/Private key, digital signature, Digital Certificate, and private value storage capability of a TCPA TPM. By itself, such technology does not solve the problem, though. There are several requirements that still need to be met.
