摘　　要：研究了软件锁常用的实现方法,提出了利用计算机硬件设备内部指纹信息作为软件钥匙进行身份认证的设计思想.软件开发时,将需要随软件分发给用户的硬件设备分别采集其指纹信息并嵌入到程序内部;软件应用时,自动检测指定硬件设备的指纹信息,通过与软件内部嵌入的已知指纹信息进行比对,实现软件锁的钥匙功能.实践表明,该方法设计简单,使用方便,可以代替某些专用硬件加密设备,达到较高强度的身份认证效果.The common achievement method of software locks is studied, the design idea of identity certification that using the computer hardware internal fingerprint as software key is proposed. When development, the fingerprint information in user＇s hardware that distributed with the software need to be collected, and must be embedded into the internal program. When application, the fingerprint information in the specified hardware is detected automatically, and compare with the known fingerprint information embedded within the software, the key function of the software lock is realized. Practice shows that this method is designed simple, easy to use and can replace some dedicated hardware encryption devices to achieve higher strength identity certification effect.
