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.

Abstract: Embodiments of this application relate to a method and a device for protecting privacy. The method includes: sending, by a remote terminal, a first message to a mobility management entity by using a relay terminal, where the first message includes first identity information of the remote terminal, and the first message is used by the mobility management entity to obtain an international mobile subscriber identity IMSI of the remote terminal based on the first identity information of the remote terminal, where the first identity information is a proximity service relay user key identity PRUK ID. Because the first identity information is used to replace the IMSI, interception of the IMSI by the relay terminal is avoided, and user privacy is protected.

Abstract: If a first SIM card in a terminal device has been registered with a first service provider, when needs to subscribe to a second service provider for registration, the terminal device sends a subscription indication and a subscription identity to a second service provider server. The second service provider server acquires service registration information from a first service provider server according to the subscription indication and the subscription identity, generates a second profile for accessing a second service provider network based on the service registration information which is used by the first SIM card to access a first service provider network. The second profile is generated based on existing service registration information, so the terminal device subscribes to the second service provider for registration. After performing subscription for registration once, no need to submit an identity for verification again, user operations are simplified and user experience is improved.
