发明名称 Protection method against copying of computer software
摘要 The protection system used to prevent copying of software involves the generation of a physical defect or change on the storage system, such as the disc or CD-ROM. The data is analysed and the result is documented and stored. When the data is installed for use, it allows a comparison to be made with a similar analysis made of the disc being used. This identifies if the installation disc in authentic or not, and if not blocks the use.
