Abstract: 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.

Key words: software copyright, computer fingerprint, ciphertext, MD5, DES
