When transmitting position/time information calculated by means of a GPS function to a server apparatus, authentication is carried out with the server apparatus. The position/time information may be certified as legitimate measured by a portable apparatus with a GPS reception function employed by a user. When transmitting information related to the position and the time acquired from a portable phone terminal having the GPS function and a network function by means of the GPS function to the server apparatus, authentication is carried out between the portable phone terminal and the server apparatus. The position/time information is transmitted to the server apparatus, only if the server apparatus is authenticated as a legitimate counterpart for connection. A secret key holding section is provided for holding different secret keys for different apparatuses. The position/time information measured based on an electromagnetic wave received from a positioning satellite is digitally signed by means of the secret key. The identification information and the position/time information having the digital signature are then transmitted to a counterpart.       Recently Added Patents Method and apparatus for data transmission Wipe with pattern for embossing Neck brace Photovoltaic ice dam remediation apparatus Preparation of (2R,3R)-3-(3-methoxyphenyl)-N,N,2-trimethylpentanamine Mechanical full draw, hold, lock and arrow release device for compound bows Network-wide inter-cell interference minimization via coordinated multipoint cell scheduling coordination   Randomly Featured Patents Method and apparatus for monitoring the condition of a battery by measuring its internal resistance Composite type recording apparatus, data writing method and data writing program Communications unit, system and methods for providing multiple access to a wireless transceiver Ink for ink jet printing Common ground control switch for an irrigation system Method for preventing plasticizer bleeding on polyvinyl chloride shaped articles System including tuned AC magnetic field transmit antenna and untuned AC magnetic field receive antenna Integrated current-limiter device for power MOS transistors Synchronous address and data multiplexed mode for SRAM Ski brake © 2006-2008 PatentGenius.
