摘要： To exclude any unauthorized device from a system and thereby prevent illegal use of content data, a memory card 10 stores a service key Ksrv for encrypting content key data Kc in a hidden area 14. The memory card 10 stores answer data ACto be obtained when question data Q is fed to a host function F possessed by an authorized host device 20, with encryption applied to the answer data AC by the service key Ksrv. When the question data Q is provided to the host device 20, answer data AH is obtained based on the question data Q and the host function F. A comparison unit 122 judges match or mismatch of the answer data AH and the answer data AC. When they match, the memory card 10 decrypts the content key data Kc encrypted by the service key Ksrv and sends it to the host device 20.

摘要： Provided is a surgery assistance system to perform relatively fast and accurate alignment between three-dimensional surface shape data acquired by measurement using a three-dimensional surface shape scanner and three-dimensional internal shape data acquired in advance, even when the position of the patient and the surface shape of the skin of the patient change during the surgery. A surgery assistance system (1) includes a three-dimensional surface shape scanner (20) for acquiring three-dimensional surface shape data by measuring a three-dimensional surface shape of a patient (60) and a computing device (40) for processing the data from the three-dimensional surface shape scanner. The computing device stores therein three-dimensional internal shape data of the patient that is acquired in advance by measurement using a three-dimensional tomography scanner (30). The computing device has a unit that aligns the three-dimensional internal shape data and the three-dimensional surface shape data with each other by using data of a portion where a distance between a skeleton and a skin surface is small in the three-dimensional internal shape data and three-dimensional surface shape data corresponding to this portion.

摘要： A handheld device is configured to be connectable to a storage media that holds a unique media identifier and holds a content key data used to decrypt an encrypted content data. A content data delivery system is provided that is configured to be able to deliver various data to the handheld device and to make a content data available to the handheld device. The system includes a member-registration information database that holds member-registration information including a data pair of a handheld-device identifier related to the relevant handheld device and the relevant media identifier. The media identifier held by the storage media is verified with the member-registration information database. When it is determined that the media identifier corresponds to the member-registration information, the content key data held in the storage media is read, and it is determined whether an encrypted content data corresponding to the read content key data is stored in the storage media or other storage media coupled to the storage media. The encrypted content data is transferred to the storage media or the like depending on the user's specification.

摘要： A system for providing program information has a user terminal, a recording medium capable of reading information therefrom and writing information thereto through a command issued by the user terminal, and a server connected to the user terminal via a network, and provides program information from the server to the recording medium. The recording medium has a first control unit that performs a first mutual authentication operation with a first storage unit capable of writing program information thereto and the user terminal, and that executes a command to write program information to the first storage unit only if the first mutual authentication operation is successful. The user terminal performs a second mutual authentication operation with the server, obtains program information transmitted from the server if the second mutual authentication operation is successful, and issues a command to write the program information to the first storage unit of the recording medium.

摘要： In a forward error correction method and a forward error correction addition apparatus, error correction is performed on the basis of data, to which forward error correction code is added, transmitted through a network to output decoded data. The data transmitted through the network includes information bits represented by an information bit matrix with n rows and m columns (n, m are natural numbers), and redundancy bits represented by an odd number of redundancy information bit rows and an odd number of redundancy information bit columns based on the information bit matrix, which are provided in the row direction and in the column direction of the information bit matrix respectively. The redundancy bits are the forward error correction code.
