数据残留的清除与安全性研究

随着各种存储设备的广泛应用和数据恢复技术的迅猛发展，数据安全越来越为用户所重视，而硬盘和其他移动存储设备作为当今数据存储的主要载体，清除残留在其中的秘密数据将面临巨大挑战。通过研究硬盘数据残留产生的原因以及现状对其安全性进行了分析，并根据当前的数据恢复技术提出了一种如何安全清除数据残留的新方法和实现算法。

Study on the Sanitization and Security of Data Remanence

As the extensive application of storage devices and swift development of data recovery technology, data safety is more and more paid attention by users, and hard disk with other moving storage device is the major carrier that stocked data, sanitizing the secret data in which will be faced with huge challenge. By researching the present situation hard disk data remanence as well as reason, its safety is analysd, and according to current data recovery technology have put forward a kind of new method-how to sanitize data safely and its implement algorithm.
