Classification: CPC G | IPC G

Claim 16:
17. The electronic device according to claim 16, wherein the fingerprint image subnetwork is obtained through training based on a fingerprint image training set comprising the plurality of fingerprint images for training, the vibration-sound signal subnetwork is obtained through training based on a vibration-sound signal training set comprising the plurality of vibration-sound signals corresponding to the plurality of fingerprint images for training, and the processor is further configured to:
input the fingerprint image of the fingerprint input action into the fingerprint image subnetwork to obtain a first feature vector;
input the vibration-sound signal generated by the fingerprint input action into the vibration-sound signal subnetwork to obtain a second feature vector;
fuse the first feature vector and the second feature vector to obtain a third feature vector;
classify the third feature vector to calculate a classification result; and
determine, based on the classification result, that the fingerprint input action is generated by the true finger or generated by the fake finger.
