Electronic device and control method
First Claim
1. An electronic device comprising a controller that changes an authentication level that is used to perform unlocking on locking based on a locking function according to a travel state of a user, whereinthe locking by the locking function is a state where only an unlocking on the locking operation is accepted,the travel state includes a state where the subject device is placed on a still object, a stopping state where the user who carries the subject device is stopping, a walking state where the user who carries the subject device is walking, a running state where the user who carries the subject device is running, and an on-state where the user who carries the subject device is on an automobile or a train, andthe controller is configured to determine the travel state when performing the locking and performing the unlocking on the locking, and changes the authentication level on the basis of a first travel state that is a result of determination made when the locking is performed and a second travel state that is a result of determination made when the unlocking is performed.

Abstract
An electronic device includes a controller that changes an authentication level that is used to perform unlocking on locking based on a locking function according to a travel state of a user. The controller acquires first biometric information that is acquired by a biometric information acquisition module in association with an unlocking operation, determines an unlocking condition on the basis of the changed authentication level, calculates a matching rate between the first biometric information and second biometric information that is set and registered in advance, and when it is determined that the matching rate satisfies the determined unlocking condition, performs unlocking on the locking.

1. An electronic device comprising a controller that changes an authentication level that is used to perform unlocking on locking based on a locking function according to a travel state of a user, wherein
the locking by the locking function is a state where only an unlocking on the locking operation is accepted, the travel state includes a state where the subject device is placed on a still object, a stopping state where the user who carries the subject device is stopping, a walking state where the user who carries the subject device is walking, a running state where the user who carries the subject device is running, and an on-state where the user who carries the subject device is on an automobile or a train, and the controller is configured to determine the travel state when performing the locking and performing the unlocking on the locking, and changes the authentication level on the basis of a first travel state that is a result of determination made when the locking is performed and a second travel state that is a result of determination made when the unlocking is performed.

9. An electronic device comprising a controller that changes an authentication level that is used to perform unlocking on locking based on a locking function according to a travel state of a user, wherein the controller
determines whether there is a change in the travel state during a period after the locking is performed until the unlocking is performed on the locking, maintains the authentication level at a standard level when the result of the determination represents that there is a change in the travel state, and lowers the authentication level to a level lower than the standard level when the result of the determination represents that there is not a change in the travel state.

10. An electronic device comprising a controller that changes an authentication level that is used to perform unlocking on locking based on a locking function according to a travel state of a user, wherein
the controller calculates a travel speed of a subject device, determines whether there is a change in the travel state during a period after the locking is performed until the unlocking is performed on the locking, when the result of the determination represents that there is a change in the travel state, the controller determines whether the travel speed exceeds a threshold, the travel speed being obtained when the travel state changes and when the travel speed exceeds the threshold, the controller increases the authentication level to a level higher than a standard level for a given time.

11. A control method comprising:
-
performing first control to perform locking based on a locking function; performing second control to determine a travel state of a user according to the performing of the locking; performing third control to, after the second control, determine the travel state again in response to acceptance of an input of first biometric information, performing fourth control to change an authentication level that is used to perform unlocking on the locking on the basis of a result of determining the travel state at the second control and a result of determining the travel state at the third control; performing fifth control to determine an unlocking condition on the basis of the authentication level; performing sixth control to calculate a matching rate between the first biometric information and second biometric information that is set and registered in advance; and performing seventh control to perform unlocking on the locking when the matching rate satisfies the unlocking condition, wherein the locking by the locking function is a state where only an unlocking on the locking operation is accepted, the travel state includes a state where the subject device is placed on a still object, a stopping state where the user who carries the subject device is stopping, a walking state where the user who carries the subject device is walking, a running state where the user who carries the subject device is running, and an on-state where the user who carries the subject device is on an automobile or a train, and determining the travel state when performing the locking and performing the unlocking on the locking, and changes the authentication level on the basis of a first travel state that is a result of determination made when the locking is performed and a second travel state that is a result of determination made when the unlocking is performed.
