Abstract: In this era of information explosion, bad information of the network is full of daily life. In order to build a clean network environment and realize the Uyghur web page detection and filtering of sensitive information, by analyzing the characteristics of the Uyghur, the Uyghur is done stemming and encoding processing. Combining the DFA and the decision tree, it puts forward the corresponding method for Uyghur sensitive information filtering. After stemming and encoding processing, it solves the Uyghur writing sequence, form of diversity, and storage with garbled words easily problems, etc. And then combining the characteristics of the decision tree, the transcoding Uyghur is stored on the decision tree node, and the child nodes of the decision tree are arranged in order in accordance with the specific code. So the information of Uyghur text can narrow the detection range when the information is filtered, and improve the efficiency of algorithm.

Key words: sensitive information filtering, deterministic finite automaton, Uyghur filter, decision tree
