A fingerprint identification device including a light source, a processor, and a light receiver is provided. The light source emits a light beam to an object. The light receiver captures an object image of the object in a time interval. The processor analyzes the object image to obtain a fingerprint image, and performs a fingerprint identification operation on the fingerprint image to obtain a fingerprint identification result. The processor further analyzes the object image to obtain pixel change data of the object image in the time interval, and determines whether the fingerprint image is verified according to the fingerprint identification result and the pixel change data. A fingerprint identification method is also provided.
