Abstract: In a digital information recording/reproducing apparatus, information recorded on a hard disk with copy restriction thereof is protected from being copied onto other hard disks by means of a PC, etc., to be produced a large number of illegal copies, i.e., infringing a copyright. The information is recorded onto a hard disk drive through encryption thereof, with using an identification being number unique thereto, when it is recorded onto the hard disk. With this, normal reproduction is prevented, since the drive identification number necessary for decryption is different from, even if it is copied onto the other hard disk. Also, a version information of the hard disc is memorized in an information management circuit. When the information is illegally copied onto the other hard disc, the version information is changes; therefore it does not coincide with the version information memorized in the information management circuit.

Abstract: A memory card (110) conducts an authentication process with a server based on data stored in an authentication data hold unit (1400). The memory card (110) extracts a first session key (Ks1) from a server by a decryption process and a transaction ID from the data applied on a data bus (BS3). The memory card (110) generates a second session key (Ks2) through a session key generation unit (1418), and transmits to the server, as the keys to encrypt content data in receiving decryption of content data, the second session key (Ks2) and a key (KPm(1)) unique to the memory card (110) in an encrypted state with the first session key (Ks1). The transaction ID and the second session key (Ks2) stored in the log memory (1460) are used in the redistribution process.

Abstract: Image evaluation method capable of objectively evaluating the image resolution of a microscope image. An image resolution method is characterized in that resolution in partial regions of an image is obtained over an entire area of the image or a portion of the image, averaging is performed over the entire area of the image or the portion of the image, and the averaged value is established as the resolution evaluation value of the entire area of the image or the portion of the image. This method eliminates the subjective impressions of the evaluator from evaluation of microscope image resolution, so image resolution evaluation values of high accuracy and good repeatability can be obtained.

Abstract: In a data processing system, a plurality of modules connected to a system bus thereof are assigned with identifiers. When a source module initiates a split read access to another module, the source module sends an address of the access destination module and an identifier of the source module. When sending a response to the source module, the destination module returns response data and the identifier of the source module thereto. Checking the identifier from the destination module, the source module determines the response data returned as a response to the initiated access.

Abstract: Data stored in a data storage system is hashed to generate a hash value. The hash value and a request for a time stamp are then sent to a time stamping authority. A time stamp token and/or a time stamp certificate is received from the time stamping authority. The time stamp token includes a time stamp and the hash value, and may be encrypted using a private key of the time stamping authority. The time stamp token and/or time stamp certificate is then stored with, for example, a reference to the data being stored in the data storage system. The time stamp token and/or time stamp certificate may then be used to validate the data being stored and the time stamp.

Abstract: When investigating a failure occurring in a transaction between information processing apparatuses, it is possible to reduce the time required for the failure investigation. A first local ID for identifying a transaction processing of first information processing apparatus is related with a standard ID for relating transaction processing of the first and the second information processing apparatuses with each other the related IDs and are stored in a first mapping table. The standard ID and a transaction processing request are transmitted to the second information processing apparatus to request execution of a transaction processing therefor. If a failure occurs in the requested transaction processing, a standard ID of the transaction processing concerned is specified to inquire a second local ID for identifying the transaction processing. Mapping information for relating the first local ID corresponding to the specified standard ID with the transmitted second local ID is generated.

Abstract: To provide a technique whereby a value of an error recovery level determined in negotiation processing between an initiator and a target can be set to a suitable value that is intended by a manager. A storage system comprises a storage section containing a target module that is connected to an initiator device; and a management section that manages the storage section. The target module carries out negotiation processing with the initiator device so as to determine a value of a first error recovery level. The first error recovery level is determined as the smaller of a value of a second error recovery level of the initiator device and a value of a third error recovery level of the target module. The management section carries out setting processing for allocating the initiator device that is to be connected to the target module to the target module, according to an instruction from a manager. In the setting processing, the value of third error recovery level is notified to the manager.

Abstract: In an optical disk drive device, in order to reduce structural vibration noise and aerodynamic sound during high-speed revolution, a recess is formed at the deeper end. This recess is in a position axially symmetric to a hole for the movement of an optical head with respect to the axis of a spindle motor, and its size is substantially equal to that of the movement hole. This recess serves to suppress the vibration mode of a disk tray and the air flow between the disk and the disk tray. Noise is reduced even when the disk is turning at high speed.
