Abstract: A biometric authentication system includes an information terminal having ID information, an acquisition terminal that acquires biometric information, and an authentication processing apparatus. The processing apparatus includes: a first part that acquires the ID and location information on the information terminal; a second part that communicates with the acquisition terminal to acquire the biometric information; a first storage part for storing an indication that the information terminal is located within a predetermined range; a second storage part that stores the ID and biometric reference information; and a controller.

Abstract: Apparatuses and method capable of reliably tracking processes through which products have passed without calling for expensive setup are necessary in production and distribution processes of the products. A process management apparatus including a data transmission/reception unit to and from an RFID tag of an information recording medium and a data generation unit comprises a process data generation unit for representing a process, a process pass certificate data generation unit for generating process data pass certificate data and a transmission/reception unit for the process data with the information recording medium and the process pass certificate data can track the processes through which the object products have passed.

Abstract: An IC tag system is provided which can perform transfer of a method of accessing an IC tag and assure data validity of the IC tag only between authorized users. The IC tag system comprises a data write-in device including a password encryption unit (130), a signature generation unit (140) and a data write-in unit (150) operative to communicate with the IC tag (30) to write in data and an encrypted password in the IC tag (30) and set the limitation on access to the data written in the IC tag (30) by the aid of the password, and a data read-in device including a password decryption unit (230), a signature authentication unit (240) and a data read-in unit (250) operative to communicate with the IC tag (30) to read in the data and the encrypted password from the IC tag (30) and release the limitation on access to the data by the aid of the decrypted password.

Abstract: An electronic device system has an electronic device including at least one pair of an identifier and a validity flag. Identifier information and condition are registered into the identifier within the electronic device. When an access is made to the electronic device using an ordinary command, no response will be made since the validity flag is “irresponsive”. An identifier is transmitted to the electronic device using an identifier control command and if the condition is satisfied, the validity flag is set to be “responsive”, and thus operation to the electronic device becomes executable hereinafter. If the condition is not satisfied, the validity flag is set to be “irresponsive”, and thus no response will be made by the electronic device.
