Design and implementation of safety fax server

Lack of preventive measures against junk fax is a great problem in the research on fax server. Safety fax server is proposed in this paper, which detect the received fax before distributing them in order to prevent users from junk fax. Because junk faxes spread in the form of broadcast, the server carries on preliminary flitting by clustering the incoming fax at first, and then uses Optical Character Recognition (OCR) technology to recognize the keywords and distinguish the junk fax. Proved by experiment, this method is not only easy to implement, but also available.
