The invention discloses a control method and device used for electronic device with full-screen
fingerprint recognition. The method comprises the following steps that: detecting whether a user requests to execute a preset operation or not; when a detection result shows that the user requests to execute the preset operation, determining a preset operation area; detecting whether the user inputs
fingerprint information in the preset operation area or not; when a detection result shows that the user inputs the
fingerprint information, judging whether the fingerprint information input by the user is consistent with preset fingerprint information or not; and when the fingerprint information input by the user is consistent with the preset fingerprint information, executing the preset operation. By use of the method, the
fingerprint recognition is used for the control of the electronic device, unlocking can be realized, the method also can be used for security assurance, including the information of network social tool,
mobile phone number storage information,
mobile phone short message information and the like, and the arrangement position and the acting range of the
fingerprint recognition can be enlarged. Through a way that the fingerprints of different fingers are changed, and position change can be realized on the basis of the full-screen
fingerprint recognition to execute different preset operations.
