A wearable terminal (2) is configured to send authentication information and first acceleration data that is output from an acceleration sensor (27) to a portable terminal (1). An acceleration sensor (9) of the portable terminal (1) is configured to output the first acceleration data. A lock control module (14) is configured such that when a locking function is set, the release of the locking function is controlled on the basis of whether the first acceleration data and second acceleration data indicate that the wearable terminal (2) and the portable terminal (1) are held by the same user when the authentication data sent from the wearable terminal (2) is valid. |
