  • Patent number: 7472278
    Abstract: A method of authenticating an object in which a computer system receives indicating data from a sensing device. The indicating data is generated in response to sensing of coded data and is indicative of an identity of the object and a plurality of signature fragments, the signature being a digital signature of at least part of the identity. The computer system uses the indicating data to determine the identity and the plurality of signature fragments. The plurality of signature fragments are then used to determined a determined signature, which is in turn used to generate a generated identity. The identity is then compared to the generated identity to authenticate the object.

  • Patent number: 7362860
    Abstract: This invention allows the encryption side to set whether an image playback apparatus should play back image data in a scrambled state or a non-scrambled state. When a code-block of input image data is an object to be encrypted, it is encrypted. In playing back the data, it is determined whether playback is to be executed by using the encrypted code-block (the scrambling playback mode is to be set). To inhibit use of the encrypted code-block, a terminating marker is placed at the start of the code-block. To use the encrypted code-block, the terminating marker is placed at the end of the code-block.
