Abstract: An information processing method, performed by a computer configured to receive a beacon signal from a transmission source, includes: executing a calculation processing operation that includes calculating a length of a monitoring period, based on time intervals at which the beacon signal is received in a period of duration of a stationary state of the computer; and executing a determination processing operation that includes determining as being out of an area in proximity to the transmission source of the beacon signal in a case where the beacon signal is not received during the monitoring period having the length.

Abstract: An information processing system includes a GW and a portable communication device. The GW includes a transmitter that transmits, to the portable communication device that is located within a given area, a request to transmit information; a receiver that receives a response to the request to transmit information from the portable communication device; and a data acquisition controller that, when the number of responses received is larger than a maximum allowable number to the GW, adjusts the area to which the request to transmit information is transmitted such that the number of responses is equal to or smaller than the maximum allowable number and that, when the number of responses is equal to or smaller than the maximum allowable number to the GW, adjusts an area to which the request to transmit information is transmitted, which is an area different from the area to which the request has been transmitted.

Abstract: A system includes a server including first circuitry and a plurality of terminals, each of which includes second circuitry respectively. The first circuitry is configured to store primes assigned to the plurality of terminals, acquire two or more primes assigned to two or more terminals that and are destinations of contents, calculate a first product of the two or more primes, and transmit first notification data including the first product and the contents to the plurality of terminals. The second circuitry is configured to store an assigned prime, receive the first notification data, determine whether the first product included in the first notification data is divisible by the assigned prime, and acquire, from the first notification data, the contents included in the first notification data based on a result of a determination.
