For example, if the first direction is a horizontal screen direction, the first fingerprint template is a fingerprint template preset when the user uses the terminal with the display direction of the screen being the horizontal screen direction.
In this embodiment, when the fingerprint does not match the first fingerprint template, there are two cases; in the first case, the orientation of the terminal is the first orientation, but the user uses the terminal with the display orientation of the screen being the second orientation. In the second case, the placing direction of the terminal is the second direction, and the user uses the terminal in the second direction of the display direction of the screen.
Illustratively, the first direction is a landscape screen direction and the second direction is a portrait screen direction. When the putting direction of the terminal is the horizontal screen direction, two conditions exist: firstly, for example, when a user watches a movie, the user uses the terminal in the display direction of the screen which is the transverse screen direction, and the fingerprint acquired by the fingerprint identification array is matched with a preset first fingerprint template; secondly, for example, when the user lies on his side to send a message, the user uses the terminal in the vertical screen display direction of the screen, and the fingerprint acquired by the fingerprint identification array is not matched with the preset first fingerprint template. When the placing direction of the terminal is vertical to the screen direction, the user uses the terminal in the vertical screen direction of the display direction of the screen, and the fingerprint acquired by the fingerprint identification array is not matched with the preset first fingerprint template.

For example, if the first direction is a horizontal screen direction, the first fingerprint template is a fingerprint template preset when the user uses the terminal with the display direction of the screen being the horizontal screen direction.
In this embodiment, when the fingerprint does not match the first fingerprint template, there are two cases; in the first case, the orientation of the terminal is the first orientation, but the user uses the terminal with the display orientation of the screen being the second orientation. In the second case, the placing direction of the terminal is the second direction, and the user uses the terminal in the second direction of the display direction of the screen.
