For example, in the case of the finger overdrying or overly moist of user, user may repeatedly press fingerprint recognition module
It can not be unlocked.In embodiments of the present invention, in these cases, whether the fingerprint image that can detect user's input belongs to dry
The fingerprint image of the fingerprint image of finger or wet finger, if it is not, fingerprint image can be matched with preset fingerprint template,
First matching value is obtained, first matching value can be judged, if first matching value is less than preset range, can be recognized
It is not the fingerprint image of terminal householder for the fingerprint image, therefore, the method in the embodiment of the present invention can be to a certain extent
Antitheft, if the first matching value is in preset range, it is the fingerprint of terminal user to illustrate the dry finger-image or wet finger-image
Image, then, the second fingerprint image of finite number of time in preset time, can be obtained, by the second fingerprint image obtained each time
As being matched with preset fingerprint image, if the first matching value and whole fingerprint images in the finite number of time and preset fingerprint mould
Adding up and more than or equal to above-mentioned first predetermined threshold value for multiple second matching values of plate, then be unlocked to terminal.If first
Matching value and the first fingerprint image of the finite number of time in preset time and tiring out for multiple second matching values of preset fingerprint template
Plus and less than above-mentioned first predetermined threshold value, then keep holding state.
