<p><P>PROBLEM TO BE SOLVED: To stabilize operation of a system that employs communications using a living body or moving body as a transmission path, such as electric field communications. <P>SOLUTION: The tag communication device includes: an encryption key generation section for generating an encryption key; a first communication section for receiving tag data or encryption key from the communication tag and transmitting the encryption key to the communication tag through data communications with the communication tag carried by or installed in the living body or moving body via the living body or moving body; an encryption section for encrypting the tag data received from the communication tag by the first communication section using the encryption key generated by the encryption key generation section and generating encrypted data; a storage section for storing the encrypted data generated by the encryption section; a decoding section for acquiring the tag data by decoding the encrypted data stored in the storage section using the encryption key received from the communication tag by the first communication section; and a second communication section for transmitting the tag data acquired by the decoding section to an information processor. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
