Power sensitive information detection method based on e-mail interception

Abstract

The invention relates to a power sensitive information detection method based on e-mail interception. The method comprises the following steps: (1) the e-mails sent by all the hosts in a local area network through email clients and partial web mails are monitored and intercepted; (2) the intercepted e-mails are analyzed according to special rules, the basic information of the e-mails are analyzed and stored; (3) the pattern recongnition and image processing technologies are utilized to analyze the analyzed e-mail information to judge whether the e-mails contain power sensitive information; and (4) if an e-mail contains power sensitive information, the system gives an alarm and returns the information of the host which sends the e-mail. By using the method of the invention, the e-mails sent by all the hosts in the local area network through email clients and partial web mails can be intercepted and analyzed effectively; and the power sensitive information which may be contained in the e-mails is analyzed and judged and further the alarm is given, thus the important documents of the power department can be effectively prevented from leaking and the network security of the power department can be ensured.
