基于特征选择的文件安全监控研究

he security of computer has always been a critical problem in IT field. For some important sensitive documents could be stolen or falsified, the file monitor will help protect these files and could be found by the administrator. In this paper, we study the technology of the traditional monitor system, and analysis of its shortcomings. Based on the existed searching engine mechanism, we suppose a suggestion that is based on feature selection in text classification techniques applied to the monitor system. We describe the overall framework and the workflow of the monitor system in detail. The design ideas, key technology and the feasibility of the system are also be discussed in this paper.
