Problems solved by technology

[0004] However, based on the above-mentioned fingerprint unlocking principle of the terminal device, when the user triggers a clear command to delete the fingerprint data corresponding to the unlock fingerprint of a certain system, the terminal device will also delete the fingerprint data corresponding to the unlock fingerprint of the system. Fingerprint data corresponding to all unlock fingerprints of other operating systems of the device, so it may violate the user's willingness to use

Embodiment Construction

[0034] The terms "first" and "second" in the description and claims of the embodiments of the present invention are used to distinguish different objects, rather than to describe a specific sequence of objects. For example, the first indication information and the second indication information are used to distinguish different indication information, rather than describing a specific order of the indication information.

[0035] In the embodiments of the present invention, words such as "exemplary" or "for example" are used as examples, illustrations or illustrations. Any embodiment or design solution described as "exemplary" or "for example" in the embodiments of the present invention shall not be construed as being more preferred or more advantageous than other embodiments or design solutions. Rather, the use of words such as "exemplary" or "such as" is intended to present related concepts in a concrete manner.

Abstract

Embodiments of the present invention provide a method and device for clearing fingerprint data, which relate to the field of communication technology, and can delete fingerprint data corresponding to a certain operating system without affecting fingerprint data of other operating systems. The method is applied to a terminal device, the terminal device includes at least two operating systems, and the method includes: receiving a fingerprint clearing instruction, the fingerprint clearing instruction is used to instruct to clear fingerprint data; and according to the fingerprint clearing instruction, determine the fingerprint identification of the fingerprint to be cleared , the fingerprint to be cleared includes at least one fingerprint; and if the fingerprint to be cleared is the fingerprint corresponding to the current activation system, delete the fingerprint feature data of the fingerprint to be cleared according to the fingerprint identification of the fingerprint to be cleared, and the current activation system is the operation currently used by the terminal device system.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular to a method and device for clearing fingerprint data. Background technique [0002] With the development of communication technology, multi-system terminals emerge as the times require. Multi-system terminals refer to terminal devices that support multiple operating systems. Users can switch to different operating systems according to different usage requirements. [0003] At present, for different operating systems on the terminal device, different unlocking fingerprints can be entered. For example, if the terminal device supports three operating systems, which are recorded as system 1, system 2 and system 3 respectively, the user enters an unlocking fingerprint for system 1. Fingerprint, record as fingerprint 1, enter two unlocking fingerprints for system 2, record as fingerprint 2 and fingerprint 3, enter three unlocking fingerprints for sys...
