摘　　要：为了解决数据在失控状态下的安全问题,提出了一种数据自毁方法。该方法定时对数据进行失控检测,一旦发现数据失控,立即将其彻底擦除,使其不可恢复,防止数据泄密。整个过程无须人工干预,耗费时间短。理论分析和实验结果表明该方法是数据保护的一种有效的新途径。In order to solve the security problems of the data out of control, this paper presented a data self-destruction method. The method regularly detected the state of the data. When the data was detected out of control, it would be thoroughly erased immediately, and it could not be restored. Data leaks were prevented. The whole process doesn＇ t need human intervention, and lasts a short time. The theoretical analysis and the experiment results show that the proposed method is a new good approach of data protection.
