Intranet Spam Monitoring Software Design

With the rapid development of Internet, people use the Internet more convenient and the people's lives and the office are very easy. E-mail technology is a typical network of convenient means of modern communication for people to call a very land of convenience, but also has many negative effects, such as adverse information, viruses, malicious programs, which are attached to the e-mail to people a lot of trouble, and the security of the Internet has also brought hidden dangerous, so to solve the enterprise network of spam is a great realistic significance.On the Internet, it is the most widely used e-mail data, this accounted for the entire application data more than 70%, an average of 1.4 billion e-mail, but more than half of those messages are spam, which seriously affect the a web mail service provider's network resources, system resources, storage resources. To solve these increasingly serious impact of spam is the current computer network communications major research questions, this thesis is based on an analysis of the study concluded that propose their own solutions.Based on the status of spam, the analysis of the basic working principle of e-mail, and e-mail filtering technology, the basic definitions and methods described, combined with Bayesian algorithm, this thesis realizes Chinese spam filter involved in the relevant technical analysis, the final algorithm based on Bayesian spam filtering system, and system-related experiments and analysis. The system testing and performance is summed up the advantages and disadvantages of the system, and the current spam filtering technology key and difficult to analyze, but also the prospect of anti-spam technology to make certain statements.
