摘要
分析目前常见软件版权保护技术的优点和不足,设计一种基于计算机指纹的软件版权保护方法。该方法使用用户计算机的指纹信息和软件的附加信息作为用户计算机的特征信息,对这些特征信息用MD5算法和DES进行两次加密生成密文,用生成的密文对软件的版权进行验证,达到保护软件版权的目的。
After analyzing the advantages and disadvantages of current ordinary shareware copyright protection technologies,a method about how to protect software is designed,which is based on computer fingerprint.In this method,the software uses the fingerprint information of user computer and additional information of software as the feature information of the user computer,and uses these feature information to generate ciphertext by two encryptions using MD5 algorithm and DES,and then uses this ciphertext to validate the software copyright and to achieve the purpose of protection of software copyright.
