A method to discover sensitive information in classified network based on web information extraction

According to the sensitive information exposure problem without authority in the classified network caused by negligence or even malice during the web construction in secret units, this paper proposes a discovery method to extract the sensitive information in the web pages based on Web information. Through hypertext transfer protocol connection module this method firstly realizes the function of acquiring all content in the web pages, and then uses regular expression technology to mark all sensitive information in every single web page. With the marked pages the method then uses the analysis function to judge whether the page belongs to the illegal pages and via the database management module stores the results of the analysis. Finally the method through visual display technology reveals the analysis results. Experiments show that this method based on information extraction technology can quickly and effectively find the sensitive information network has been released to help managers promote the efficiency of website maintenance.
