Disclosed herein is a peripheral equipment control device controlling data flow via a peripheral equipment, the peripheral equipment control device including: a peripheral equipment control processor that can control an operation of one or more peripheral equipment; and a bus adapted to connect the peripheral equipment control processor, a main processor, and the one or more peripheral equipment, the main processor being provided outside the peripheral equipment control device to control the operation of the one or more peripheral equipment, in which the bus stores addresses that are referenced by the main processor and the peripheral equipment control processor to access the one or more peripheral equipment, and the bus prohibits access to the peripheral equipment by the peripheral equipment control processor while the main processor is active.

Peripheral equipment control device and information processing

A game playing system includes a use permission tag provided for use in a game disk for a user of a game, a disk drive, and a reproduction device for reproducing the game. The disk drive reads out a disk ID from the game disk. When the game is to be played, the reproduction device conveys the disk ID and a player ID to the use permission tag. The use permission tag stores the terms of use of the game and determines whether a combination of the disk ID and the player ID conveyed from the reproduction device fulfills the terms of use or not.

Electronic content processing system, electronic content processing method, package of electronic content, and use permission apparatus

Managing the use of an optical disc drive by a program at high security. An OS of a host apparatussends one user certificate incorporating the policy information defining the use contents permissible for the optical disc driveand a user key to the optical disc driveunder a secure environment (S). On the other hand, the program running on the OS is authorized, and the user key is passed to the authorized program (S). The optical disc driveauthorizes the program using the user key within the user certificate and the user key for the program and specifies the policy information corresponding to the user key (S). Thereafter, the optical disc drivepermits the application program to gain access to the self-resource within the limits of the contents defined in the policy information (S).

Use management method for peripheral device, electronic system and component device thereof

There are provided a multisystem network, and a device and method for access to a data storage unit in order to allow processors in a plurality of devices to access the data storage unit. The data storage unit has a data storage area divided in a first area for a first device and a second area for a second device. The first and second devices are connected to the data storage unit via a connection circuit. A first processor in the first device can access directly the data storage unit. The connection circuit has provided therein an emulation register corresponding to a register which stores a command or control data used for the first processor in the first device to access the data storage unit. A second processor in the second device accesses the data storage unit via the emulation register and with intervention of the first processor.
