The multiple systems may include the same type of operating system, and may also include different types of operating systems. For example, the terminal device may be a dual-system terminal device, and the dual system may be the same type of operating system, for example, all of the Android system, or The dual system can also be a different type of operating system, for example, one is an Android system, and the other is an Apple IOS system. The embodiment of the present application is not limited thereto.

In the embodiment of the present application, the terminal device includes multiple systems, where each system corresponds to one fingerprint template set, that is, the fingerprint identification device sets a fingerprint template set for each system, for example, the terminal device includes the first system, and the The first system corresponds to a first fingerprint template set.

In the embodiment of the present application, the user requests to perform a target operation, and the target operation needs to perform fingerprint recognition, and the user inputs the target fingerprint to perform fingerprint recognition. Specifically, when fingerprinting is performed, the fingerprint identification device collects the target fingerprint of the user, and the target fingerprint is preferentially matched with the fingerprint template set corresponding to the current system. For example, when the first system is currently used, the fingerprint identification device collects the target fingerprint. a fingerprint template in the first fingerprint template set corresponding to the target fingerprint Make a match.

S350. Perform a new fingerprint related operation of the current system, and the fingerprint related operations may include registering a new fingerprint template operation, changing a fingerprint template operation, and identifying an operation.

It should be understood that after the system completes the handover, the corresponding fingerprint identification device also switches the fingerprint template set. When the user inputs a new fingerprint to be detected, the fingerprint to be detected preferentially matches the new current system. For example, the terminal device is switched from the first system to the second system, and the current system is changed to the second system. When the user inputs a new fingerprint to be detected, the fingerprint to be detected preferentially matches the second fingerprint template corresponding to the second system. The collection is matched.
