Application research of finite automaton in distance education

The internet-based distance education is one of the important ways to establish Lifelong Learning System; the design of network course is an important research topic of it. Based on analyzing present situation and existing problems of network course in China, this paper introduces the finite automata theory, and in order to guarantee the security of information, puts forward a method of using the finite automaton to monitor and filter the text information inputted by using the synchronous or asynchronous communication tools provide by network course. The results show that our method is effective.
