Because the fingerprint daemon service of the terminal equipment runs in a management system (which can be called a host system), if the operating system currently used by the terminal equipment is the system 1, the terminal equipment is in a screen locking state, and the terminal equipment can be unlocked through the fingerprint 1 and enters the system 1 currently used; if the operating system currently used by the terminal device is the system 1, the terminal device is in the screen locking state, and the terminal device can be switched from the system 1 to a system corresponding to the fingerprint through the fingerprint (such as the fingerprint 2, the fingerprint 3, the fingerprint 4 or the fingerprint 5) other than the system 1, and the terminal device can be unlocked.
However, based on the above fingerprint unlocking principle of the terminal device, when the user triggers a clear instruction to delete the fingerprint data corresponding to the unlocking fingerprint of a certain system, the terminal device deletes the fingerprint data corresponding to the unlocking fingerprint of the system, and also deletes the fingerprint data corresponding to all the unlocking fingerprints of other operating systems of the terminal device, so that the user will be violated.

It should be noted that, in the embodiment of the present invention, the terminal device executing the fingerprint data removal includes at least two operating systems, that is, the terminal device supports at least two operating systems, a user may use a corresponding operating system according to a use requirement, and the user may trigger the terminal device to remove the fingerprint data of one fingerprint, or may remove the fingerprint data of all fingerprints corresponding to a certain operating system. The following describes an exemplary method for removing fingerprint data according to an embodiment of the present invention from a scenario in which one fingerprint is removed and a scenario in which all fingerprints corresponding to one operating system are removed.
First, in a scenario of removing fingerprint data of a fingerprint, as shown in fig. 2, a method for removing fingerprint data according to an embodiment of the present invention may include S101-S103:
s101, the terminal equipment receives a fingerprint clearing instruction which is used for indicating clearing of fingerprint data.
In the embodiment of the invention, a user can perform corresponding operation on the terminal equipment to trigger the terminal equipment to start to clear the fingerprint data, and the operation for triggering fingerprint clearing is a fingerprint clearing instruction.
For example, a user may enter a setting module on the terminal device to set a lock screen, a password, and a related menu of fingerprints, and under a fingerprint management entry, for a certain one or more collected fingerprints, the user selects an option to delete the fingerprints (e.g., click a delete fingerprint button), and the terminal device detects an operation of the user, that is, the terminal device receives a fingerprint removal instruction, so that the terminal device starts to perform a related action to remove fingerprint data in response to the operation to delete the fingerprints by the user.
It should be noted that, in the embodiment of the present invention, the related action of removing the fingerprint data is completed by interaction between a fingerprint daemon service (may also be referred to as a fingerprint daemon service) and a fingerprint hardware abstraction module (may also be referred to as a fingerprint hal) in the terminal device.
S102, the terminal equipment determines the fingerprint identification of the fingerprint to be cleared according to the fingerprint clearing instruction.
Optionally, in the embodiment of the present invention, the instruction to be processed to remove a fingerprint may be an instruction to remove one fingerprint in a certain operating system, or may be an instruction to remove all fingerprints in a certain operating system, and for a certain operating system of the terminal device, after the user initiates an operation instruction to remove a fingerprint corresponding to the operating system, the terminal device determines, in the fingerprint daemon service, whether the instruction is an instruction to remove a certain fingerprint or an instruction to remove all fingerprints.
In an embodiment of the present invention, when fingerprint data of one fingerprint is to be cleared, the fingerprint clearing instruction includes first indication information, where the first indication information is used to indicate that the fingerprint data of the first fingerprint is to be deleted, and the first indication information includes a fingerprint identifier of the first fingerprint, where the first fingerprint is a fingerprint corresponding to one operating system.
In the embodiment of the present invention, the fingerprint array is a file created for storing a fingerprint identifier of each acquired fingerprint during a process of acquiring fingerprints by a terminal device (for example, before acquiring fingerprints or after acquiring a first fingerprint by the terminal device), and the fingerprint identifiers of the acquired fingerprints are recorded in part or all of coordinate positions in the fingerprint array, where the fingerprint identifier is an identifier capable of uniquely identifying one fingerprint.
For example, assume that the terminal device includes 2 operating systems, respectively denoted as operating system 1 and operating system 2, and an example of a fingerprint array is shown as follows:
for example, in the above fingerprint array, the first row correspondingly stores the fingerprint identifier of the fingerprint corresponding to the operating system 1, and the second row correspondingly stores the fingerprint identifier of the fingerprint corresponding to the operating system 2. Note that, in the fingerprint array, an element having a value of 0 represents no fingerprint identification. As can be seen, the operating system 1 has two fingerprints whose fingerprint identifiers are 93299486 and 93299487, respectively, and the operating system 2 has three fingerprints whose fingerprint identifiers are 93299500, 93299501, and 93299502, respectively.
In this embodiment of the present invention, if the first indication information indicates to clear the fingerprint data of the 2 nd fingerprint in the operating system 1 (i.e. the first fingerprint mentioned above), the fingerprint identifier of the first fingerprint is 93299487.
And S103, if the fingerprint to be cleared is the fingerprint corresponding to the current activation system, the terminal equipment deletes the fingerprint characteristic data of the fingerprint to be cleared according to the fingerprint identification of the fingerprint to be cleared.
The current activation system is an operating system currently used by the terminal equipment.
In the embodiment of the invention, each operating system of the terminal equipment has access right, for example, the terminal equipment has the right to delete the fingerprint data corresponding to the currently activated system, but the currently activated system has no right to delete the fingerprint data corresponding to other operating systems. If the fingerprint to be removed is the fingerprint corresponding to the currently activated system, the terminal device deletes the fingerprint feature data (also referred to as a fingerprint template) of the fingerprint to be removed according to the fingerprint identifier of the fingerprint to be removed without affecting the fingerprint data corresponding to other operating systems, i.e., without deleting the fingerprint data corresponding to other operating systems, so that the user experience is not affected.
Specifically, if the fingerprint data of one fingerprint is deleted, the application layer directly transmits the fingerprint identifier of the fingerprint to be removed from the fingerprint framework layer service to the fingerprint daemon service, and the fingerprint daemon service determines that the fingerprint to be removed is the fingerprint corresponding to the current activation system, the fingerprint daemon service sends the fingerprint identifier of the fingerprint to be removed to the fingerprint hal, and the fingerprint hal deletes the fingerprint feature data identified by the fingerprint identifier, namely the fingerprint template.
Optionally, with reference to fig. 2, as shown in fig. 3, after S102, the method for removing fingerprint data according to the embodiment of the present invention may further include S104:
and S104, the terminal equipment determines whether the fingerprint to be cleared is the fingerprint corresponding to the current activation system.
Optionally, as shown in fig. 3, if the fingerprint to be removed is not the fingerprint corresponding to the currently activated system, the following S105 is executed:
and S105, the terminal equipment stops deleting the fingerprint feature data of the fingerprint to be cleared.
In the embodiment of the invention, if the fingerprint to be removed is not the fingerprint corresponding to the current activation system, the terminal equipment has no authority to delete the fingerprint data of the fingerprint to be removed, so that the terminal equipment stops deleting the fingerprint feature data of the fingerprint to be removed.
Optionally, with reference to fig. 3, as shown in fig. 4, before the foregoing S101, the method for removing fingerprint data according to the embodiment of the present invention may further include S106-S108:
s106, the terminal device creates a fingerprint array.
In the embodiment of the present invention, when the terminal device collects fingerprints for each operating system, before the terminal device collects the fingerprints, or after the terminal device collects fingerprint data of a first fingerprint, the terminal device may create one piece of data according to the number of operating systems included in the terminal device and the number of fingerprints allowed to be entered by each operating system, so as to store a fingerprint identifier corresponding to each fingerprint.
And S107, generating fingerprint identification of the fingerprint according to the acquired fingerprint.
In the embodiment of the present invention, the fingerprint identifier may be a fingerprint id (identity) or other identifiers defined by a user, which is not limited in the embodiment of the present invention.
And S108, writing the fingerprint identification into a fingerprint array.
Illustratively, assuming that the terminal device includes 2 operating systems, a maximum of 5 fingerprints can be entered for each operating system, and the terminal device can create an array of 2 rows and 5 columns. Specifically, when a fingerprint is actually acquired, two fingerprints, namely fingerprint 1 and fingerprint 2, are entered in the operating system 1, three fingerprints, namely fingerprint 3, fingerprint 4 and fingerprint 5, are entered in the operating system 2, and in the created 2 rows and 5 columns, fingerprint identifiers of the two fingerprints corresponding to the operating system 1 are written in 2 of the 5 positions in the first row, and fingerprint identifiers of the three fingerprints corresponding to the operating system 2 are written in 3 of the 5 positions in the second row, for example, after the fingerprint identifiers are written in, the fingerprint array is:
wherein, some positions in the array are not written with the fingerprint identification, and at the positions, the complement of 0 is adopted to represent that no fingerprint identification exists.
