Abstract: A prediction apparatus, comprising an acquisition unit configured to acquire peripheral information of an own vehicle, a determination unit configured to determine, based on the peripheral information, whether a behavior prediction target on a road visually recognizes a predetermined object, and a prediction unit configured to, if it is determined by the determination unit that the behavior prediction target visually recognizes the predetermined object, predict that the behavior prediction target moves across the road in a crossing direction.

Abstract: An information processing apparatus that authenticates sets of distributed authentication information without collecting, the sets of distributed authentication information, to be collected at any one of apparatuses included in a system.

Abstract: In order to provide a server device and the like that are capable of quickly extracting data without need for a client that performs a query of search processing to have a secret key. A server device includes: data storage unit that stores concealed registration data including distribution information of registration data distributed by secret sharing scheme and a ciphertext of the registration data encrypted by searchable encryption; token calculation unit that generates a token for data search of the searchable encryption by communicating with an external server device and performs secret computation by using a search query and the distribution information; and data search unit that performs data search from the token for data search received from the token calculation unit and the concealed registration data acquired from the data storage unit, and outputs a search result.
