A system for privacy protection includes a processor and a terminal including a location detection device. The processor performs: identifying a presence possible ranges of the terminal at a first time and at a second time earlier than the first time from a combination of information on a first region including the location at the first time, and information on a second region including the location at the second time and having been already transmitted to an external apparatus; determining whether each of the identified presence possible ranges satisfies a preset condition for a presence possible range that may be known by a third party; when the condition is not satisfied, transmitting the information on a third region including the first region and a region other than the first region, as information on a region where the terminal is present at the first time, to the external apparatus.

Information processing apparatus, information processing system, and privacy protection program

An information processing method executed by a first information processing device which is a candidate of a distribution source of data to a terminal and which moves to be associated with a first wireless access point, the information processing method including: obtaining state information on a second information processing device; determining an information processing device that continuously distributes data to a terminal from among the first information processing device and the second information processing device, in accordance with state information on the first information processing device and the state information on the second information processing device obtained in the obtaining; and distributing data to a terminal through the first wireless access point and a second wireless access point associated with the second information processing device when the first information processing device is determined in the determining.

Information processing device, information processing system, and information processing method

An information processing apparatus includes a memory and a processor coupled to the memory. The processor is configured to identify a reducible message string by using state transition information. The reducible message string is used to reduce a message string held in a message queue. The state transition information indicates a relationship between a message for executing a service and transition of a state of the service. The processor is configured to detect the reducible message string included in the message string. The processor is configured to reduce the message string held in the message queue by using the reducible message string.

Information processing apparatus and distributed processing method

An information processing method, performed by a computer, includes: acquiring a beacon signal from a radio circuit coupled to a processor of the computer and configured to receive the beacon signal from a transmission source; 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 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.

Determining a computer being out of an area of beacon transmission

An information providing method includes: measuring a static object three-dimensionally in an environment, by a processor; sequentially measuring a position of a dynamic object in the environment, by the processor; transmitting measurement data of the static object measured to a predetermined information processing apparatus through a communication network; transmitting measurement data of the dynamic object measured to the information processing apparatus through a communication network; receiving support data rem the information processing apparatus based on an environment grasping image that is generated from the measurement data, of the static object and the measurement data of the dynamic object by the information processing apparatus; and presenting the received support data to the environment at predetermined timing, by the processor.

Information providing method, information providing apparatus, information processing apparatus, information providing system, and computer-readable recording medium

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.
