Abstract
An apparatus, computer program product, and method are disclosed for access control to a mobile terminal. A use end event is generated indicating an end of use of a mobile terminal. Acceleration of the mobile terminal is binarized by the mobile terminal after the use end event is generated to one of a first value indicating a stationary state and a second value indicating a moving state. A use start event is generated indicating a start of use of the mobile terminal. A movement preparation period is measured from a time at which the use end event is generated to a time at which a transition from the first value to the second value occurs. Use authentication is requested in response to the use start event and in response to the movement preparation period exceeding a first threshold.
