  • Terminal apparatus and system thereof
    Patent number: 8260714
    Abstract: A terminal apparatus is provided which guarantees operation of a use condition bytecode while securing a degree of freedom for a service provider generating the use condition bytecode. A terminal apparatus (300), in which a license (1200) includes a use condition determining logic code (1204) and a version number (1202), includes a license obtainment unit (304) obtaining the license (1200), a use condition verification unit (302) determining, based on the version number (1202), whether or not an operation of the use condition determining logic code (1204) has been confirmed, a use condition bytecode execution unit (303) executing the use condition determining logic code (1204) when the operation of the use condition determining logic code (1204) has been determined to have been confirmed, and a content playback unit (306) playing back content based on the use condition determining logic code (1204).

  • RFID tag and RFID tag communication distance modification method
    Patent number: 7834743
    Abstract: It is possible to prevent an unauthorized read-out from both active tags and passive tags. Antenna emission is turned on and off by using a switch, or attenuated by using a resistor. A part of the antenna may be chipped. With these configurations, it is possible to lower the emission level of the antenna thus preventing an unauthorized read-out of important information from a remote reader.

  • TERMINAL APPARATUS, SERVER AND SYSTEM THEREOF
    Publication number: 20100088750
    Abstract: A terminal apparatus is provided which can guarantee operation of a use condition bytecode while securing the degree of freedom for a service provider generating the use condition bytecode. A terminal apparatus (300), in which a license (1200) includes a use condition determining logic code (1204) and a version number (1202), includes a license obtainment unit (304) which obtains the license (1200), a use condition verification unit (302) which determines, based on the version number (1202), whether or not the operation of the use condition determining logic code (1204) has been confirmed, a use condition bytecode execution unit (303) which executes the use condition determining logic code (1204) when the operation of the use condition determining logic code (1204) has been determined to have been confirmed, and a content playback unit (306) which playbacks content based on the use condition determining logic code (1204).
