Maintenance System For The Accumulation Of Knowledge-based Trigger Rule

With the rapid development of the Internet, hackers can invade the Pentagon and Telecommuniations Buraeau, and other complex systems, and can easily steal personal privacy and bank account number. Data security issues have become increasingly prominent. Data erasuie is one of the most effective ways to solve the data security. However, at present, many domestic commercial products (such as WOM) although have supply the basic function of data wiping, these softwares have common following problems: 1) the destruction strategy is single, only one strategy can be chosed, which leads to the poor choice of users and users cannot choose a suitable method according to the antual situation. 2) The efficiency of data wiping is relatively low which cannot wipe the sensitive data rapidly. And this may result in some or all of the data fall into others'hands. 3) Have not wiped some temporary data, which may also lead to the loss of sensitive data. 4) The wiping process requires manual intervention. The systerm can not determine to wipe the data by judging the situation automatically which may delay the best time of data wiping.In this paper, I designe and implemente a trigger system which is based on the traditional single function of data wiping to meet the above-mentioned problems. This system provides a rule database and the algorithms of data wiping which makes up of an active defense data self-wiping system. The principle of the accumulation of knowledge ensures the rule database's comprehensiveness and safety of the whole system.
