A Spam Detection Method on Backbone Network Based on Suffix Tree
Guo Li · Computer Engineering and Applications Journal · 2006
Although there are a lot of studies for filtering and detecting spam,most of them are for E-mail clients.In this paper,we propose a new spam detection method on backbone network based on suffix tree.It represents the text of E-mail with suffix tree structure,and uses the variable length string matching method to decide the similarity between mails,then uses the count of similar mails to determine whether mails are junk mails or not.This method didn't require any training corpus,and directly classifying and counting accepted mails.It took time and space to detect the mail of length.Besides,this method is independent of language.
