Abstract: The present invention increases the ease of use of an optical code in which an digital signature is recorded. Recorded in the optical code are: a message; an digital signature created from the message using a creator's secret key; and a public key ID with which it is possible to specify the creator's public key certificate that includes a public key paired with the secret key, said ID being smaller in size than the public key certificate. An optical code readout authentication device, after reading the optical code, acquires the creator's public key certificate from a certificate provision server on the basis of the recorded public key ID, and uses the public key certificate to authenticate the optical code.

Abstract: An optical code is readable by a generally used reading device, and optically readable as an information code that can appropriately prevent abuse due to duplication. In this optical code, data is recorded with a pattern of a plurality of light-color modules having high visible light reflectance and a plurality of dark-color modules having visible light reflectance lower than light-color modules. At least either the light-color modules or the dark-color modules are configured to include a first module and a second module having reflectances different from each other for invisible light of a predetermined wavelength. Thus, data is recorded as a readable pattern of modules, the pattern being differently observed between when irradiated with visible light and when irradiated with the invisible light of a predetermined length.

Abstract: A data code label including a QR code and an ID tag including a memory having an identification code area and a decode data writing area. A data code in the QR code showing an error in decoding is corrected and stored in the memory in the ID tag while the degree of defection of the QR code is low. When the defects advance, the error rate will increase. If the error occurs after advance of defects, the decode data in the memory is read when the error is detected. If the decode data cannot be read, the error correction is effected. If the error rate is higher than a reference, the decode data is obtained from the memory. If this decreases the error rate under the reference, the error correction is effected.

Abstract: A remote care service system comprises the care center (attended by a care worker), a first-aid center, and the plurality of home subsystems, each comprising a relay terminal and at least one wireless care recipient monitoring terminal disguised as an attachment-arousing and/or familiar article. The care and first-aid centers and the wireless terminals are accessible to a communication network such as the Internet. The relay terminal relays a communication between an associated wireless terminal and the center equipment. The wireless terminal tries an interactive communication with the care recipient by using a predetermined phrase to judge whether the care recipient is normal. If not, then the wireless terminal sends an abnormality report to the first-aid center, which responsively dispatches emergency men to the care recipient's home. Judgment the care recipient's health condition interactively with the care recipient enhances the reliability of the judgment.

Abstract: An identification tag is attached to or imbedded in each article a plurality of which are located nearby or stacked together. The identification tag wirelessly communicates with a remote controller such as a hand-held terminal to send data or receive command. Electric power to operate the identification card is also wirelessly supplied from the remote controller. The electric power is received only by a particular identification card which is communicating with the remote controller, and is turned off when the communication is completed. The electric power is then supplied to the next identification card which communicates with the remote controller. Thus, all the identification tags sequentially send data thereof one by one to the remote controller. The remote controller includes an indicator that indicates whether the communication with all the identification tags is completed, so that the remote controller can be positioned at a right place until the end of the communication.
