摘要： A data transfer system comprises a plurality of terminals; a plurality of high-speed data transfer units connected to the terminals through a network, each data transfer unit comprising a plurality of storage devices and a storage device group control device or unit for controlling readout of data from the storage devices, and dividing and storing data requested by the terminals; a virtual storage device group controlling device or unit for controlling readout of data from virtual storage device groups, each virtual storage device group being constructed by selecting a storage device from each high-speed data transfer unit; and an instruction conversion unit or device for receiving a data readout instruction on the basis of data requests output from the terminals, which instruction is given to the virtual storage device groups, from the virtual storage device group control unit or device, and converting the instruction into a data readout instruction to the storage devices from the storage device group control unit or device. In this data transfer system, the load for the data transfer processing is equally distributed among the high-speed data transfer units even when data transfer requests are output from plural terminals.

摘要： A predetermined number of erasable blocks positioned at a start of a volume area in a semiconductor memory card are provided so as to include volume management information. A user area following the volume management information includes a plurality of clusters. A data length NOM of an area from a master boot record & partition table sector to a partition boot sector is determined so that the plurality of clusters in the user area are not arranged so as to straddle erasable block boundaries. Since cluster boundaries and erasable block boundaries in the user area are aligned, there is no need to perform wasteful processing in which two erasable blocks are erased to rewrite one cluster.

摘要： An encrypted-data decrypting apparatus that provides enhanced security protection for programs and data while they are in the processes of decryption to execution after having been encrypted. When a decrypted partial program needs to be loaded into the shared memory M, the controlling unit 11 loads it into an area indicated by the memory location information. According to the memory location information, a plurality of partial programs are sequentially loaded into an area so that one partial program gets overwritten by another; therefore, none of the partial programs exists in the memory for a long time, and thus there is less possibility of having the partial programs referred to illegitimately. In addition, since every time some data is decrypted, the decryption support program authenticating unit 13 confirms authenticity of the decryption support program P, it is possible to prevent having illegitimate references in which the decryption support program is abused.

摘要： A distribution server 103 distributes a content via a network, and a KIOSK terminal 105 receives the content via the network and records the content in an SD memory card 100. A customer device 111 receives a content via the SD memory card 100, checks out the content and records a copy on a recording medium. SD-Audio players 122 to 124 receive a copy of the content and play back the copy. Here, the KIOSK terminal 105 records a Usage Rule that certifies the right to control recording of content on the SD memory card 100. Move Control Information showing the number of times that moving of rights is permitted is set in the Usage Rule.

摘要： A program execution device capable of protecting a program against unauthorized analysis and alteration is provided. The program execution device includes an execution unit, a first protection unit, and a second protection unit. The execution unit executes a first program and a second program, and is connected with an external device that is capable of controlling the execution. The first protection unit disconnects the execution unit from the external device while the execution unit is executing the first program. The second protection unit protects the first program while the execution unit is executing the second program.

摘要： The present invention comprises a program generation apparatus for generating an obfuscated program difficult to analyze from outside and a program execution apparatus for executing the program. The program generation apparatus comprises: an acquisition unit operable to acquire a 1st program including one or more instructions, the 1st program causing a process by executing the instructions in a predetermined order to obtain a result; a generation unit operable to generate a 2nd program based on the 1st program; and an output unit operable to output the 2nd program. Here, the 2nd program causes a process that is different from the process caused by the 1st program and varies according to current information determined at execution of the 2nd program in order to obtain a result identical to the result of the 1st program.
