    摘要: In a target apparatus which stores at least one piece of domain key information in a first area and a plurality of pieces of content key information each associated with any one of the domain key information in a second area, a method for generating data for detecting tampering of the content key information. The method comprises the steps of encrypting the content key information associated with one of the domain key information using a chain encryption technique, extracting data at predetermined positions in the encrypted content key information, concatenating the pieces of data extracted at the predetermined positions in the encrypted content key information to obtain concatenated data, performing a hash calculation with respect to the concatenated data to obtain a hash value, storing check values corresponding to the data at the predetermined positions in plain text, in the target apparatus, and storing the hash value in the target apparatus.

    摘要: A semiconductor memory card (101) has a plurality of areas (105, 106) based on different file systems. An adapter (102) includes: an area switching part (110) which a user can operates, a determination part (109) for determining the operation; and a card controller (108) for issuing a switching command for switching the area to be used for the semiconductor memory card (101) in accordance with the judgment result. When the switching command is issued in response to input from the area switching part (110), the command is interpreted by an area selector (107) of the semiconductor memory card (101) so as to select an area.

    摘要: An information recording medium includes a data storage section having a plurality of recording regions for storing data, and a region information storing section operable to store information about each recording region in the data storage section. The region information storing section stores information about a recording region (for example, a recording region has been accessed finally) which is set first as an accessible region when the information recording medium is initialized at the next time among a plurality of recording regions in the data storage section. A data processing apparatus refers to the information about the recording region and changes over a recording region to the recording region specified by the information about the recording region just after initialization of the recording medium.

    摘要: An information recording medium (100) is a recording medium to/from which data can be written/read from a data processing apparatus. The recording medium includes a host interface (110) for communicating with the data processing apparatus, a data storage section (130) having a plurality of recording regions (#1, . . . ,#N) for storing data, and a region information storage section (124) for storing information on each recording region. The region information storage section (124) stores information about address attribute of each recording region of the data storage section (130). The information about the address attribute includes information indicating unit (byte or sector) of address specified on access to the recording region.
