摘　　要：分析目前常见软件版权保护技术的优点和不足,提出了一种虚拟加密锁的共享软件版权保护方法,用动态链接库DLL文件代替加密锁,将软件的关键功能模块、基于用户计算机指纹的注册验证模块和反破解模块封装在动态链接库文件中,从而模拟加密锁达到保护共享软件版权的目的。该方法已应用于共享软件的版权保护中。After analyzing the advantages and disadvantages of current ordinary shareware copyright protection technologies, this paper pro- poses a sort of shareware copyright protection method based on virtual encryption lock, which substitutes DLL file with software eneryption lock,encapsulates key function modules,registration verification module based on user＇ s computer fingerprint and anti-cracking modules into DLL file to reach the aim of protecting shareware＇ s copyright by simulating software encryption lock. The method has been applied to the shareware copyright proteetion devised by the author.
