Embodiment Construction
[0037] Exemplary embodiments will be described in detail herein, examples of which are illustrated in the accompanying drawings. Where the following description refers to the drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated.
[0038] The invention provides a method for fingerprint deletion in dual operating systems, which is applied to electronic equipment with dual operating systems, figure 1 It is a schematic diagram of an electronic device with dual operating systems, such as figure 1 As shown, the electronic device 100 is divided into a software layer and a hardware layer, and the operation of the software layer depends on the hardware layer. The software layer includes dual operating systems: a first operating system 11 and a second operating system 12 . The first operating system 11 and the second operating system 12 may be two different types of operating systems installed in the electronic device 100 a...

The embodiment of the invention provides a method and device for deleting fingerprints in double operating systems, and the method comprises the steps: reading state information in a starting process of a first operating system, the state information is used for indicating that fingerprint data corresponding to a target operating system is not deleted in a factory setting restoration process, and if the fingerprint data is deleted, the target operating system is deleted; and when the first operating system is the same as the target operating system in the state information, deleting the fingerprint data corresponding to the first operating system and the state information. When the target operating system is started as a foreground operating system, the target operating system generates the state information before restoring the factory settings, and the state information is not deleted in the process of restoring the factory settings; according to the embodiment of the invention, the non-deleted fingerprint data of the target operating system in the process of restoring the factory settings can be deleted according to the state information, and the fingerprint data is deleted in the starting process of the operating system without being perceived by a user, so that the use of the operating system by the user is not influenced.
Description
technical field [0001] The present invention relates to the technical field of communications, and in particular, to a method and device for deleting fingerprints in dual operating systems. Background technique [0002] With the rapid development of communication technology and electronic equipment, electronic equipment installed with a single operating system can no longer meet user needs. Therefore, electronic equipment applications with two operating systems (hereinafter referred to as dual operating systems) are installed. [0003] The two operating systems of the electronic device run independently, the application layers of the two operating systems do not communicate with each other, and the two operating systems cannot obtain each other's information. When two operating systems share one fingerprint chip, only one operating system (the operating system currently being used by the user, also called the foreground operating system) can interact with the fingerprint chi...
