DIGITAL KEY-BASED IDENTITY AUTHENTICATION METHOD, TERMINAL APPARATUS, AND MEDIUM

Embodiments of the present invention disclose a method for authenticating an identity of a digital key, a terminal, and a medium. Before a second terminal enters a preset operating state from a non-preset operating state, first, identity authentication is performed on a user by using an identity authentication system of the second terminal, and obtained identity authentication information is stored in a secure element of the second terminal. Then, when a digital key in the second terminal needs to be used, the identity authentication information stored in the secure element of the second terminal is sent to a first terminal, and the first terminal may perform verification based on the identity authentication information to determine whether the user using the digital key in the second terminal is an authorized holder of the second terminal. By using this method, even if the second terminal is in the preset operating state (for example, a power-off or low battery mode), an identity of the user can be authenticated when the user uses the digital key in the second terminal. This improves security of the digital key.
