SYSTEM AND METHOD FOR DETECTING SPAM MESSAGE REPRESENTING CHARACTERISTIC DIFFICULT TO BE AVOIDED OR DUPLICATED BY SPAMMERS

摘要

PURPOSE: A system and a method for identifying a spam message representing a characteristic difficult to be avoided or duplicated by spammers are provided to make the spammers hardly edit the message and remove a possibility almost that the spammers make the message pass a messaging system. CONSTITUTION: The message(140) from a sender(110) is transferred to a mail server(130) included in the system(100). A message parsing component(160) estimates/parses the message in order to induce the characteristic from origination information(150). If at least a part of origination information of the message is parsed, the parsed part or characteristic is communicated with a characteristic coupling/parsing component(170). The characteristic coupling/parsing component utilizes a characteristic couple of a result as the additional characteristics by analyzing a possible combination of the characteristics. The characteristic couples are used by a filter training component(180) linked with the system.
