Abstract
An electronic device is provided. The electronic device includes a display, a first fingerprint sensor, a second fingerprint sensor, a memory, and a processor configured to acquire a first fingerprint image corresponding to an external object requesting fingerprint authentication through the first fingerprint sensor, acquire a second fingerprint image corresponding to the external object through the second fingerprint sensor, produce a phase image based on a differential component of an area in which the first fingerprint image and the second fingerprint image overlap, identify whether the external object is a stereoscopic pattern having a three-dimensional shape through the phase image, identify whether at least one of the first fingerprint image or the second fingerprint image matches with registered user fingerprint authentication data, and when the external object is a stereoscopic pattern and the registered fingerprint authentication data is matched, succeed in the fingerprint authentication for the external object.
