An electronic device includes an inertial force sensor, a memory unit, and a control unit connected to the inertial force sensor and the memory unit. The control unit includes a characteristic-waveform processor and an authenticator. The characteristic-waveform processor is operable to generate a characteristic waveform based on output waveforms output from the inertial force sensor in response to operations performed by a first user, and to record the characteristic waveform in the memory unit. The authenticator is operable to generate a reference waveform based on one or more output waveforms output from the inertial force sensor in response to respective ones of one or more operations performed by a second user, and to determine whether or not the first user and the second user are identical to each other by comparing the reference waveform with the characteristic waveform. This electronic device performs accurate authentication with a simple structure. |
