Abstract:
A method and device for identifying multiple fingerprints. The method comprises: collecting, from a fingerprint detection area of a terminal apparatus, a fingerprint image comprising two or more fingerprints (S1); identifying the fingerprints in the fingerprint image to acquire a first fingerprint and a second fingerprint (S2); computing a distance between the first fingerprint and the second fingerprint (S3); computing an angle between the first fingerprint and the second fingerprint (S4); and when the first fingerprint and the second fingerprint match prestored fingerprint templates, and errors between the computed distance and angle and a prestored distance and angle are less than or equal to preconfigured errors, unlocking the terminal apparatus (S5).
