Abstract: In 5G cell (230) of 5G system (200), upon detecting that access to the 5G system (200) is barred, the 5G system (200) is congested, 5G core network (220) of the 5G system (200) does not support IMS-type communication service, or fallback to 4G system (300) is instructed, UE (100) selects 4G cell (330) of the 4G system (300) as a target cell for connection. The UE (100) transmits a connection request signal for the IMS-type communication service to the target cell for connection.

Abstract: A fuzzy extractor includes an initial key generating part including a true random number generator, and a key regenerating part. The true random number generator generates a true random number using a read-out signal read from the reading part or a pixel signal read from the pixels of the pixel part in a true random number generation mode. The initial key generating part generates helper data and an initial key based on the true random number generated by the true random number generator and variation information acquired as a response when the initial key is generated. The key regenerating part generates, when a key is regenerated, a unique key based on helper data acquired when the initial key is generated and variation information acquired as a response including an error when the key is regenerated.

Abstract: An information processing apparatus according to this invention, upon acquiring target data, computes an evaluation value between the target data and each piece of representative data. The information processing apparatus determines, for each piece of representative data, whether the evaluation value computed between the representative data and the target data satisfies a predetermined relationship with a threshold related to the representative data. When it is determined that the evaluation value computed between the target data and certain representative data satisfies the predetermined relationship with the threshold related to the representative data, the information processing apparatus stores the target data in a storage area related to the representative data. The information processing apparatus updates the threshold related to each piece of representative data.

Abstract: A placement device may reduce the cost for placing an object when a placement destination, in which an object is placed, changes due to the addition of a placement destination. A placement device may: determine, upon receiving object information assigned to an object, as the placement destination in which the object is placed from among one or more placement destinations each having an assigned set value, the placement destination added most recently and assigned a set value larger than a characteristic value derived uniquely based on the object information; and change, when a placement destination is added, based on an available capacity representing the amount of objects that can be newly placed in the placement destinations, the set value assigned to at least one of the placement destinations such that the determined placement destination does not change to a placement destination other than the placement destination added last.

Abstract: Disclosed is an object arrangement apparatus which arranges a plurality of objects approximately uniformly to a plurality of arrangement destinations by a comparatively easy processing configuration. This object arrangement apparatus includes an arrangement destination determination means. The arrangement destination determination means refers to sequence information generated based on unique information for objects and refers to corresponding information between arrangement destination identifiers identifying arrangement destinations of the objects and second numbers associated with the arrangement destination identifiers. The arrangement destination determination means generates first numbers by using the sequence information, the first numbers not having a correlation therebetween when the first numbers are generated with different sequence information, and repeats generating a new first number until the first number matches the second number contained in the corresponding information.
