Some disclosed methods involve obtaining current A-line data corresponding to reflections of ultrasonic waves from a target object detected by a single receiver pixel, obtaining current ultrasonic fingerprint image data corresponding to reflections of ultrasonic waves from a target object surface, obtaining previously-obtained A-line data that was previously obtained from an authorized user, and obtaining previously-obtained ultrasonic fingerprint image data that was previously obtained from the authorized user. Some disclosed methods involve estimating, based at least in part on the current A-line data, the previously-obtained A-line data, the current ultrasonic fingerprint image data and the previously-obtained ultrasonic fingerprint image data, whether the target object is a finger of the authorized user. The estimation may involve an anti-spoofing process based at least in part on the current A-line data and the previously-obtained A-line data.
