An acceleration sensor 9 of the portable terminal 1 outputs the first acceleration data. While a lock function is set to the portable terminal, when the authentication information transmitted from the wearable terminal 2 is valid, a lock control unit 14 controls release of the lock function on the basis of whether or not the first acceleration data and second acceleration data indicate that the wearable terminal 2 and portable terminal 1 are held by the same user.SELECTED DRAWING: Figure 1

Description

  The present invention relates to a mobile terminal and a lock control method for a mobile terminal.

  For example, the portable terminal described in Patent Document 1 (Japanese Patent Laid-Open No. 2013-187879) executes the specific process in a locked state in which the execution of the specific process specified in response to an input from the user is prohibited. When the above condition is satisfied, short-distance communication is performed with an authentication information recording body attached to a wristwatch owned by the user. The portable terminal acquires the ID information recorded by the authentication information recording body, and releases the lock state when the ID information is valid.
