摘要
近年来,电子数据擦除技术越来越受到重视,文章介绍了目前主流的数据填充法和物理破坏法两种擦除技术,重点阐述了硬盘自擦除技术的实现机制,并通过具体的实例论证了该技术的优势。该技术较传统的逻辑擦除技术具有更高的安全性,还可大大降低PC端的资源耗费,并能简化擦除程序的开发流程,是一种低成本、高效率的电子数据擦除技术。
Electronic data erasing technology has gained much more concern in the industry of information security in recent years.Currently there are mainly two popular data erasing methods,including pattern wiping,physical damaging which has their own advantages and disadvantages.Disk data self-erasing is a kind of new method to wipe data using the internal security mechanism,which uses the combination of several protocol commands to implement the activity of wiping data.
