    摘要： A character string retrieval system retrieves a character string corresponding to a retrieval key input thereto from a text file including a plurality of characters. The system includes an index indicating position data identifying a position of each of characters in the text file and indicating next character data identifying either a character or a character string formed of a plurality of characters arranged next to each of the characters in the text file, a selecting unit for selecting a first character from characters forming the character string corresponding to the retrieval key, a determining unit for determining, with reference to said index, whether or not a character or a character string next to the first character, selected by said selecting unit, in the retrieval key is equal to a character or a character string identified by the character data corresponding to the first character; and output unit for outputting a retrieval result when said determining unit determines that a character or a character string next to the first character in the retrieval key is equal to a character or a character string identified by the character data corresponding to the first character, the retrieval result being obtained based on the position data corresponding to the first character in said index.

    摘要： A CD-ROM stores encrypted software. When a user desires to decrypt and install this software, an approval preparatory key is generated by an installer. This approval preparatory key is generated based on time data. When the user informs a center of this approval preparatory key, the center calculates a difference between this approval preparatory key and a decrypting key and vends this calculated result to a user in the form of an approval key. When the user inputs this approval key to an installer, the installer generates a decrypting key by adding the approval preparatory key to the approval key. The installer decrypts the software by this decrypting key and installs the encrypted software into a personal computer system.

    摘要： A removable storage medium relates to a removable storage medium embodying an external storage medium for computer equipment. The removable storage medium can be inserted in an external storage apparatus connected to a computer equipment unit, and stores predetermined programs. The removable storage medium includes a correspondence table for specifying a correspondence relation between a physical drive configuration of the computer equipment unit connected to the external storage apparatus and a logical drive configuration of the stored programs. A recording device is provided for recording information on the correspondence table.

    摘要： A vendor ID is written to a system area of a write-once optical disk. When the write-once optical disk is loaded onto a write-once disk drive, a control CPU reads the vendor ID. The vendor ID is written into the header of software received through an interface unit. When the software is input to an SD circuit, the control CPU reads the vendor ID. The control CPU compares the vendor ID in the system area of the write-once optical disk with the vendor ID of the header of the software and checks whether or not the two IDs are identical. If the two IDs correspond to each other, the control CPU writes the software to the write-once optical disk.

    摘要： A method of preventing a fraudulent use of an optical disk having a read-write region and a read-only region, comprising the steps of: writing data for designating the boundary between the read-write region and the read-only region into a predetermined block of the optical disk; reading the data out of the predetermined block prior to the execution of the software recorded on an optical disk as an object of fraudulent use check; reading data out of a block which is assumed to be in the read-only region by reference to the data read out of the predetermined block, and writing the data read out of the block in the assumed read-only region into the same block; reading data out of a block which is assumed to be in the read-write region by reference to the data read out of the predetermined block, and writing the data read out of the block in the assumed read-write region into the same block; and judging that the optical disk as an object of fraudulent use check is not a fraudulent copy when the data writing operation is impossible in the block in the assumed read-only region but possible in the block in the assumed read-write region.
