Abstract: In an antitheft method for a mobile terminal that relates to the field of communications technologies, a baseband processor detects integrity of an operating system running on an application processor, generates a short message service (SMS) message when the operating system has no integrity, and transfers the SMS message to the application processor. The application processor controls a display to display the SMS message in order to inform a user that the operating system of the mobile terminal is damaged. In a scenario in which a mobile terminal is stolen and an operating system is maliciously tampered with, according to the solution provided in this application, an SMS message is used to prompt a user, thereby improving security of the mobile terminal.

Abstract: A method includes receiving a first audio signal when an electronic device is locked, where the first audio signal includes a first voice signal of a user, and the first voice signal includes a keyword for requesting the electronic device to perform a first operation, performing voiceprint recognition on the first audio signal to determine a score of the first audio signal, unlocking the electronic device and performing the first operation when the score is greater than or equal to a first threshold, prompting the user to perform security authentication in a manner other than a voice manner when the score is less than the first threshold and greater than a second threshold, and unlocking the electronic device and performing the first operation when the security authentication performed by the user succeeds.
