METHOD FOR BLOCKING SPAM MAIL IN PRIVATE INFORMATION BASED AND METHOD FOR SEARCHING PRIVATE INFORMATION THEREOF

摘要

A method for blocking spam mails based on personal information and a personal information searching method thereof are provided to improve personal information search speed and apply a personal information-based spam mail blocking method in a general embedded system by searching the personal information through byte pattern comparison, not character string pattern comparison. A starting node and working nodes are defined/initialized in a personal information area of a personal information store box(S302). A keyword extracted through a context analysis of a received mail is copied(S303). Personal information items stored in the personal information area are loaded(S304). It is searched whether the keyword having the same byte pattern matched with the byte pattern of the copied keyword is found(S306). If the matched byte pattern is found, weight corresponding to the extracted keyword is assigned(S307).
