An information processing apparatus controls position measurement performed by a position measurement device. The apparatus includes a memory and a processor that executes a process in the memory. The process includes acquiring schedule information associated with the position measurement device and including a start time and an end time, acquiring position information acquired by the position measurement device, and extending a position measurement cycle of the position measurement device compared to a position measurement cycle before the start time of the schedule information when positions that respectively correspond to a plurality of pieces of position information acquired between the start time and the end time are in a given area.

Information processing apparatus, information processing method, and medium

A method for controlling an information processing system that includes a client device including a plurality of sensors that acquire positional information of the client device and a server device that transmits data to the client device includes causing the server device to specify a positioning requirement corresponding to positional information of the client device based on association information associating a distance between the client device and a location in which the server device transmits the data to the client device located with each of the sensors, and causing the client device to select a sensor based on the positioning requirement specified by the server device among the sensors.

Method for controlling information processing system, server device, and client device

A method of inferring a user's direction by a computer, the method includes: recording a relative azimuth angle obtained from an output of a direction sensor included in a terminal apparatus carried by the user; identifying the user's direction at a first point at which the user's direction is capable of being identified; and inferring the user's direction at a second point by using a relative azimuth angle corresponding to the first point and a relative azimuth angle corresponding to the second point different from the first point, and the user's direction that has been identified at the first point.

A content processing apparatus includes an extracting part extracting undownloaded contents from a list of downloadable contents, a providing situation storage part that stores a providing situation of the contents that content processing apparatus provided to other apparatuses, a priority order determining part determining the priority order of download in the extracted undownloaded contents based on the providing situation stored in the providing situation storage part, and a downloading part downloading the contents in accordance with the priority order determined by the priority order determining part.

Content processing apparatus, content processing method, and recording medium

An information processing device includes: a receiving operation for receiving, from a transmission device, content and first verification data corresponding to divided content obtained by dividing the content; a detecting operation for detecting an error of the divided content based on second verification data to be calculated based on the divided content and the first verification data received in the receiving operation; and an obtaining operation for obtaining other divided content corresponding to the divided content having the error detected in the detecting operation from another information processing device different from the transmission device, when the error of the divided content is detected in the detecting operation.

Systems and methods for detecting and correcting errors in transmitted data

A communication terminal device includes: a communication unit configured to connect to a network to transmit and receive contents among a plurality of nodes; a memory configured to accumulate a history table that stores a search history of a content search; and a processor configured to execute a process comprising: storing the search history of the content search in the history table; comparing metadata attached to a search object content that is a content search object with metadata attached to a content stored in the history table; determining whether the content stored in the history table is similar to the search object content based on the comparing of the metadata; and making the transmission unit transmit information inquiring about possession of the search object content to a node that possesses a content determined to be similar to the search object content.

Communication terminal device, computer program, and content search method

An authentication system includes node devices, wherein a first node device transmits the authentication information thereof to a second node device, the second node device selects third node devices that are requested to verify the validity of the received authentication information, and transmits the authentication information to each of the selected third node devices, the third node device records verification information that is used to verify the validity of the authentication information of the first node device, verifies the validity of the authentication information on the basis of the authentication information and verification information, and transmits the result information to the second node device, and the second node device further derives weighted values indicating the reliability of the each verification of the third node devices and authenticates the first node device on the basis of the each result information and the each weighted value received from the third node devices.

Authentication system, authentication device and recording medium

There are provided an information processing apparatus and a license distribution system including the information processing apparatus in which the reproduction or duplication of a content can be limited to the interior of a domain and a benefit based on the fact that an external device has participated in the domain can be made available at the time of reissuing a license. A reproducing devicetransmits a request for reissuing the license for permitting the reproduction of the content in the domain, and participation information (S). A serverreceives the request for reissuing the license and the participation information (S), and confirms validity of the transmitted participation information (S). When the validity of the participation information is confirmed, the serverdetermines information on a specific privilege related to the license, transmits the information to the external device (S), and reissues the license (S).
