计算机涉密数据销毁的研究与设计

摘要

With the development of information technology, more and more people rely on computers for file storage. In this situation, files leakage and illegal data recovery events occurred frequently, thus, how to effectively protect the data security has been an important issue in the field of computer security. This paper gives a brief introduction of the common methods of computer data destruction, designs and develops a file-erasing program based on the principle and structure of the data storage in Windows systems. Test results demonstrate this program can effectively prevent the illegal recovery of deleted data.%随着信息技术的发展和人们对计算机文件存储的依赖，文件泄漏和非法恢复的事件频频发生，如何有效地保障数据安全一直是计算机安全领域的重要课题。本文简要介绍了计算机数据销毁的常用方法，并基于Windows系统的数据存储原理和结构，设计和实现了一个文件擦除程序。经测试，该程序可以有效地防止已删除数据的非法恢复。
