An electronic device is provided. The electronic device includes a light source, a fingerprint sensor, a memory configured to record an image of a reflected light detected when the light source is turned on, and a processor configured to operatively coupled to the light source, the fingerprint sensor, and the memory, wherein the light source may form an irradiation area on a display surface by light irradiation to a display, the irradiation area may include a fingerprint recognition area formed on the display, at least one surface may match the fingerprint recognition area or at least one vertex coincides, and the matched area may form a first area. The memory may store instructions allowing the processor to irradiate light in a designated direction using the light source, obtain a first image and analyze the first image to distinguish whether the object detected by the fingerprint sensor is flat or three-dimensional.
