METHOD FOR RECORDING, DISTRIBUTING AND REPRODUCING INFORMATION RECORDED ON DATA CARRIERS

摘要

The invention relates to the means for protection of information and can be used in crypto systems for encoding and decoding of information stored and distributed on compact disks. The method for recording of initial information characterized in that main encrypting information is processed in such a manner, as a result of which two independent parts of information are formed: an informative part and an accessory part, each of which separately can not reproduce the initial information even in its separate parts. An accessory part of information is recorded on the disk. The informative part is encoded by individual keys of the user recorded on an additional carrier with a processor, in which the algorithm of encoding with individual keys of the user is implemented. Disks with accessory information may be distributed broadly. Therefore, the method provides full protection from unauthorized duplication, which makes no sense in this case.
