摘要： By storing an authenticator created from a data file in a secure area usually unaccessible, the alteration of the data file can be detected. Furthermore, by designating the data file as a main-file and creating authenticators from various kinds of sub-files related to the main-file, the size of the secure area where the authenticators are stored, can be reduced.

摘要： An electronic data storage apparatus includes a data storage unit for storing electronic data; an authentication information generation unit for generating authentication information used in detecting an amendment made to the stored electronic data; and an authentication information data output unit for outputting the electronic data after adding to the electronic data the authentication information generated for the electronic data. When an authorization unit authorizes the electronic data storage apparatus after it is determined that the specification of the electronic data satisfies a predetermined condition, or when mutual authentication is performed between electronic data storage apparatuses, the electronic data storage apparatus stores the data. Thus, the electronic data can be protected from being illegally amended or deleted, and can be safely stored in a format in which sufficient legal evidence can be maintained on the electronic data.

摘要： The apparatus controls access to the contents. The apparatus comprises MO device, MPEG2 decoder, and MO media as physical elements. Information for identifying these physical elements (identifying information) is allocated to each of these physical elements. License information, indicating whether access to the contents is to be allowed or not, is recorded on a MO media. Access to the contents recorded on the MO media is controlled based on the license information and the identifying information.

摘要： A computer-system fixed-priority process scheduler that is supported by an operating system (OS) and establishes fixed priorities respectively corresponding to a plurality of processes to be scheduled. Further, the priorities can be changed by designation from the user processes. The process scheduler allocates a central processing unit (CPU) to executable ones of the processes in the descending order of the priorities thereof. Moreover, a user-level process scheduler is provided in a fixed-priority process scheduler space, namely, in a real-time class process scheduler space. The user-level process scheduler has a first priority of a real time class. Furthermore, the user-level process scheduler performs the scheduling of a group of other user processes, which have priorities lower than the first priority, and causes the group of such user processes to operate or run. Namely, the user-level process scheduler determines the allocation of the CPU to such user processes and requests the OS to execute such user processes.

摘要： A memory management unit manages a memory that stores a code, and sets that the memory that stores the code to be executed is valid to make a processor execute the code stores a verification key used to verify a validity of the code in a verification-key storing unit. When the code is stored in the memory and ready to be executed by the processor, the memory management unit verifies the validity of the code using the verification key stored in the verification-key storing unit and verification information assigned to the code. The memory management unit controls to set that the memory is valid when the validity is verified by the verifying unit, and not to set that the memory is valid when the validity is not verified by the verifying unit.
