Abstract: An electronic device is provided. The electronic device includes a memory storing first authenticated fingerprint information, and a processor configured to obtain first fingerprint information corresponding to a first input, compare the first fingerprint information with the first authenticated fingerprint information during a first user authentication, perform a designated function when the first authenticated fingerprint information belongs to a first reference, temporarily store the first fingerprint information when the first authenticated fingerprint information belongs to a second reference, obtain second fingerprint information corresponding to a second input during a second user authentication, compare the second fingerprint information with the first authenticated fingerprint information during the second user authentication when the second input satisfies a designated reference in relation to the first input, store the temporarily stored first fingerprint information as second authenticated fingerprint information when the second authenticated fingerprint information belongs to the first reference, and perform the designated function.

Abstract: Disclosed herein are an electronic device and method. The electronic device includes a touch screen, at least one fingerprint sensor disposed on the touch screen, and a processor implementing the method, including controlling the touch screen to display one or more graphic objects, detecting attribute information of at least one graphic object associated with a fingerprint sensor disposed on at least a part of the touch screen from among the one or more graphic objects, activating an area of the fingerprint sensor based on the attribute information, the activated area of the fingerprint sensor corresponding to the at least one graphic object, and acquiring fingerprint information through the activated area of the fingerprint sensor.
