Provided is a transmitting terminal capable of sharing an encryption key among a number of specific apparatuses using fewer resources and securely. A transmitting terminal () has an inquiry ID generation unit () which embeds an encryption key in logical results of an XOR between an ID of a receiving terminal and random blocks according to predetermined key embedding rules in order to generate an inquiry ID. The key embedding rules are stipulations for inverting the values of bit positions corresponding to each bit value of the encryption key, in the block position correspondence relationships between the bit positions of the encryption key and the positions of the blocks into which the logical result of the XOR have been partitioned and the bit position correspondence relationships between the bit values of the encryption key and the bit positions within the blocks, which have been predefined.

An information displaying apparatus is capable of providing an easy-to-see display of information that the user wants to know out of information related to objects seen in a captured real-world image. The information displaying apparatus comprises an image input unit for inputting a captured real-world image. A distance acquiring unit acquires the distance between an object seen in the input captured real-world image and a view point of the captured real-world image. An object superimposing unit outputs an image in which information related to the object is superimposed on the captured real-world image. An information output control unit controls the information output by the object superimposing unit. The information output control unit decides, in accordance with the acquired distance, how to present the information outputted by the object superimposing unit.

A base station authentication method which allows base station authentication to be performed by more wireless terminal apparatuses within a fixed period of time. This method is a base station authentication method for TDMA wireless communication and comprises: a step in which wireless terminal apparatuses () select timeslots (S) and use the selected timeslots to transmit, to a wireless base station apparatus (), responses indicating the start of base station authentication (S); a step in which the wireless base station apparatus () generates base station authentication data summarizing information indicating whether there has been a response for each timeslot, for the plurality of timeslots (S), and transmits the generated base station authentication data to the wireless terminal apparatuses () (S); and a step in which the wireless terminal apparatuses () perform base station authentication on the transmission origin of the base station authentication data, based on whether the received base station authentication data indicates that there were responses at the selected timeslots (S).

Provided is a biometric authentication system capable of preventing spoofing attacks even if leakage of key information and a registration conversion template occurs. A communication terminal device () calculates secret key information k' which is exclusive OR of key information k of the registration biological information and masked value c&#x2032; which is randomly selected from a predetermined error correction code group, and calculates verified information c&#x2032;&#x2033; which is exclusive OR of sent information c&#x2033; and value c&#x2032;. A biometric authentication device () calculates exclusive OR of authentication biological information, information k&#x2032;, and registration conversion template w, as information c&#x2033;, wherein the template w is exclusive OR of information x, information k, and authentication parameter c randomly selected from the code group; and performs biometric authentication on the basis of a degree of matching between information c&#x2032;&#x2033; corresponding to information c&#x2033;, and the parameter c.
