  • Patent number: 11881011
    Abstract: A fingerprint anti-counterfeiting method and an electronic device are provided. The fingerprint anti-counterfeiting method includes: After detecting a fingerprint input action of a user, an electronic device obtains a fingerprint image generated by the fingerprint input action, and obtains a vibration-sound signal generated by the fingerprint input action. The device determines, based on a fingerprint anti-counterfeiting model, whether the fingerprint input action is performed by a true finger. 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.

  • Publication number: 20230379408
    Abstract: An electronic device receives a first input operation performed by a user; determines a to-be-positioned target device and a predetermined moving track in response to the first input operation; and obtains WI-FI feature information of the target device or a WI-FI hotspot apparatus with a known geographical location and motion information of a first electronic device in a process in which the first electronic device moves along the predetermined moving track to determine and display location information of the target device such that the target device can be positioned using one electronic device, there is no need to be a plurality of known reference points, and an offline fingerprint database is not relied on.
