发明名称 METHOD OF ABOLISHING UNAUTHORIZED COPYING OF DIGITAL DATA STORED ON AN OPTICAL DISC
摘要 A method of abolishing unauthorized copying of digital data stored on an optical disc includes the steps of distributing overwrite modules of a copy protection module into a data file that is to be protected against illegal copying, so as to form a copy-protected data file; and writing the copy-protected data file into a non-rewriteable optical storage media. The overwrite modules are respectively located between any two adjacent data blocks of the data file, such that each data block and a following overwrite module together form a group and the copy-protected data file includes a plurality of sequentially arranged groups of data block and overwrite module. With the overwrite modules, data blocks read out by a readout device are repeatedly overwritten by subsequent data blocks in a specified register, so that no data file from the optical storage media will be stored in the specified register and be illegally copied or pirated.
