Abstract
A data copyright management apparatus for handling data copyrights, and data of digital cash and video conference system is provided. The data copyright management apparatus comprises a CPU, ROM, EEPROM, and RAM. The ROM, EEPROM, and RAM are connected to the CPU bus, and a system bus of a device which utilizes the data can be connected to the CPU bus. A data copyright management system program, crypt algorithm, and user information are stored in the ROM, and a first public-key, a first private-key, a second public-key, a second private-key, a first secret-key, a second secret-key, a copyright information are stored in the EEPROM. The data copyright management apparatus may be configured in the form of a monolithic or hybrid IC, a thin IC card, PC card, insertion board, and further, may be incorporated in a computer, television set, set-top box, digital video tape recorder, digital video disk recorder, digital audio tape apparatus, or personal digital assistants, and the like.
