摘要： A fingerprint anti-counterfeiting method and an electronic device are provided. The fingerprint anti-counterfeiting method includes the following steps: After detecting a fingerprint input action of a user, an electronic device obtains a fingerprint image generated by the fingerprint input action (S61), and obtains a vibration-sound signal generated by the fingerprint input action (S62). The device determines, based on a fingerprint anti-counterfeiting model, whether the fingerprint image and the vibration-sound signal are generated by a fingerprint input action of a true finger (S63). The fingerprint anti-counterfeiting model is a multi-dimensional network model obtained through learning based on fingerprint images for training and corresponding vibration-sound signals. The fingerprint anti-counterfeiting method in embodiments of this application helps improve a protection capability of the electronic device for a fake fingerprint attack.

摘要： This application provides a fingerprint anti-counterfeiting method and an electronic device. The method includes: An electronic device detects a first operation of a user; the electronic device obtains a fingerprint image and a touch signal in response to the first operation; and the electronic device determines, based on the fingerprint image and the touch signal, that the fingerprint image is a fingerprint image of a real finger or a fingerprint image of a fake finger. The fingerprint anti-counterfeiting method in embodiments of this application helps improve accuracy in recognizing a fake fingerprint.
