Patent ID: 11455826

Abstract:
A method for identifying a fingerprint, a fingerprint identification apparatus and an electronic device are provided. The method includes: acquiring light signals in multiple directions reflected via a sampled object above a display screen; generating a plurality of two-dimensional 2D fingerprint images respectively based on the light signals; determining whether the sampled object is a three-dimensional 3D object based on the plurality of 2D fingerprint images; and if the sampled object is the 3D object, performing fingerprint identification based on at least one of the plurality of 2D fingerprint images. A distinction between a 2D object and a 3D object is effectively achieved through the light signals in the multiple directions, and when the sampled object is a 3D object, subsequent fingerprint identification is performed, which fundamentally avoids performing the fingerprint identification based on a fake fingerprint captured by a 2D object, thereby improving security of the fingerprint identification.
