Abstract: 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 (400) has an inquiry ID generation unit (420) 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.

Abstract: 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.

Abstract: A base station authentication method which allows base station authentication to be performed by more wireless terminal apparatuses within a fixed period of time.

Abstract: 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 (300) calculates secret key information k? which is exclusive OR of key information k of the registration biological information and masked value c? which is randomly selected from a predetermined error correction code group, and calculates verified information c?? which is exclusive OR of sent information c? and value c?. A biometric authentication device (500) calculates exclusive OR of authentication biological information, information k?, and registration conversion template w, as information c?, 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?? corresponding to information c?, and the parameter c.

Abstract: A device for giving importance information according to a video operation history includes an interest video searching operation block detection unit provided with a minimum searching operation block detection unit for detecting a minimum searching operation block as a minimum unit which exists in an interest video searching operation block from a preview log as a video operation history of a user, and a searching operation block setting unit for setting the interest video searching operation block through determination with respect to an operation previous and subsequent to the detected minimum searching operation block as a base point based on a feature of the interest video searching operation block.

Abstract: A wireless terminal is provided that can ensure security while gathering a communication history using little memory. The wireless terminal (200) has a secure ID generation unit (221) for generating a secure ID that includes a terminal ID, and a transmission unit (224) for broadcasting the secure ID generated by the secure ID generation unit (221). The secure ID generation unit (221) writes a different terminal ID for each transmission on a first portion of the secure ID, and, on a second portion of the secure ID, writes the terminal ID that had been written on the first portion of the secure ID transmitted immediately before as a link ID.
