In a risk determination method: moving body information, in which accompanying information that indicates the current position of a moving body and a current-position image that indicates a situation around the moving body at the current position are included in correspondence to each other, is obtained; and, if risk occurrence information corresponding to the current position indicated in the accompanying information included in the moving body information is not stored in a risk occurrence information manager and risk occurrence information corresponding to a position other than the current position is stored in the risk occurrence information manager, a degree of risk at the current position is determined on the basis of a similarity between the current-position image included in the moving body information and a risky-position image included in at least one piece of risk occurrence information stored in the risk occurrence information manager.

A risk information processing method used in a risk information processing system that manages a degree of risk at a spot where a moving object is located includes: storing, as risk information in a storage, a degree of risk for a combination of spot and situation; and estimating first risk information for a first combination for which a degree of risk has not been input by using three or more pieces of risk information including degrees of risk for a second combination whose spot is the same as the first combination and whose situation is different from the first combination, for a third combination whose situation is the same as the first combination and whose spot is different from the first combination, and for a fourth combination whose situation is the same as the second combination and whose spot is the same as the third combination.

An anomaly detection electronic control unit (ECU) that detects unauthorized messages on a communication path is provided. An ECU that periodically transmits a first-type message including data to be monitored, and an ECU that periodically transmits a second-type message including data for comparison, are connected to the communication path. The anomaly detection ECU includes: a receiver that successively receives first-type and second-type messages; a processor that determines whether a first-type message received is normal or anomalous; and a transmitter that transmits a predetermined message in accordance with results of the determining. The determining is performed based on content of the first-type message, content of a second-type message last received at the time of receiving this first-type message, and at least one of content of a first-type message received further in the past than this first-type message, and content of a second-type message received further in the past than the second-type message last received.

An unauthorized control suppression method for use in a network system is provided. The network system includes a plurality of electronic controllers that exchange, via a communication channel, a plurality of frames The plurality of frames includes at least one control frame that instructs predetermined control to an object of control. The method receives, sequentially, the plurality of frames from the communication channel, and determines whether the predetermined control, instructed by the control frame received in the receiving, is to be suppressed, based on a set of frames received in the receiving. The set of frames is received in the receiving within a predetermined period preceding a time of reception of the control frame.

Disclosed is a method for controlling a cordless telephone device for use in a system that allows remote control of a home electric appliance. The method includes a first generation step of causing a first generation unit in a handset to encode audio input via a sound receiving unit in the handset to generate a first stream, and a first transmission step of transmitting the first stream to a base unit. The first generation step includes causing the first generation unit to generate instruction bit information and a first instruction stream when a first trigger indicating a request to start the remote control is given to the first generation unit. The first transmission step includes transmitting the instruction bit information and the first instruction stream to the base unit through a multiplexing scheme that is common to transmission of a first stream generated when the first trigger is not given.
