A mobile device is carried by a person to be authenticated. An acceleration sensor is installed in the mobile device and configured to output an acceleration signal corresponding to acceleration applied to the mobile device. A processing device is configured to execute determination processing for determining whether the person is walking based on the acceleration signal. A control device is configured to control transmission of a radio signal, and to control an operation of a controlled device based on a result of the determination processing and a result of authentication processing for authenticating, by way of the mobile device, the person as a user of the controlled device. The determination processing is activated in response to reception of the radio signal by the mobile device.

Authentication system, mobile device, processing device, and non-transitory computer-readable medium

A mobile device possessed by a user is equipped with: a motion sensor which is capable of detecting the motion of the mobile device; a receiver which is capable of receiving a polling signal transmitted from equipment; and a control unit which is configured so as to set, in response to whether or not the polling signal has been received by the receiver, the sampling speed with which the motion sensor detects the motion of the mobile device.

Mobile device

A portable device having a built-in electronic component has normal mode, in which the electronic component functions, and power saving mode, in which power less than that consumed in the normal mode is consumed. The portable device is provided with: a use state detection unit that detects the in-use state or the non in-use state of the portable device; and a mode control unit that shifts the mode of the portable device to the power saving mode, in the cases where a fixed time has elapsed after the use state detection unit detected that the state of the portable device is shifted to the non in-use state.
