detailed description

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While the embodiments of the present invention have been shown in the drawings, the embodiments Rather, these embodiments are provided so that this disclosure will be more fully understood and the scope of the disclosure will be fully disclosed.

1 is a flow diagram of one embodiment of a method of the present invention for distinguishing a current mode from a secure mode and a non-secure mode.

In step S110, it is determined whether the application that currently calls the fingerprint sensor is a secure application or a non-secure application. If the application is a security application, step S121 is performed; if the application is a non-secure application, Then step S122 is performed.

At present, the working principle of the fingerprint sensor is: when the protruding portion of the fingerprint is placed on the sensing capacitor pixel electrode, the capacitance is increased, and the data is collected by detecting the increased capacitance. In this way, the fingerprint sensor can capture the fingerprint image, and at the same time, it can also sense the touch of the fingerprint.

The security application needs to collect fingerprint images, at least one of payment, login, unlocking, and booting; the non-secure application needs to invoke the sensing function of the fingerprint sensor, but does not need to collect fingerprint images.

Step S121, setting the current mode of the electronic device to the security mode.

Step S131, controlling the fingerprint sensor to run the fingerprint image collection function in a safe environment.

Further, in the security environment, after the fingerprint image is collected, the method further includes: extracting a fingerprint feature included in the fingerprint image, and comparing the fingerprint feature with a reference fingerprint feature in the database.

Step S122, setting the current mode of the electronic device to the non-secure mode.

Step S132: Control the fingerprint sensor to operate the fingerprint sensing function in a normal environment, wherein the fingerprint sensing function includes touch information of the sensing fingerprint, and specifically may be a position or an area where the fingerprint touches the fingerprint sensor.

In order to distinguish whether the fingerprint image is collected in the fingerprint service, the current mode of the electronic device is divided into a safe mode and a non-secure mode. If the security mode is invoked in the secure mode to support the security application, and the fingerprint sensor is controlled to run the fingerprint collection. Function; if in non-secure mode, support non-secure applications in normal environment, and control fingerprint sensor to run fingerprint sensing function. In this way, the fingerprint image of the user can be prevented from being randomly collected, and the privacy protection of the fingerprint image of the user is enhanced.

Wherein, when the current mode is the non-secure mode, the fingerprint sensor is controlled to operate the fingerprint sensing function in a normal environment, and the fingerprint image of the user is not required to be collected, and the current application implementation can be controlled according to the fingerprint touch information sensed by the fingerprint sensor. The function other than fingerprint recognition, in this way, the convenience of the fingerprint sensor can expand more functions besides fingerprint verification, and does not need to collect user fingerprint images, and these functions can be realized by using any fingerprint.

In a specific embodiment of the present invention, the security mode and the non-security mode can be switched, as shown in FIG. 2 .

In step S201, the current mode of the unlocked electronic device is set to the non-secure mode.

In this way, the electronic device that completes the unlocking action is set to the non-secure mode by default.

Step S202, detecting whether a fingerprint verification instruction is received.

Wherein, when the current application is to perform a function with high security, for example, functions such as unlocking, paying, logging, booting, etc., a fingerprint verification command is issued.

Step S203, switching the current mode from the non-secure mode to the secure mode.

When the current mode is the safe mode, the fingerprint sensor running fingerprint image acquisition function will be controlled in a safe environment.

Step S204, performing fingerprint verification in a secure environment. If the verification is successful, step S201 is performed.

The fingerprint verification specifically includes: controlling the fingerprint sensor to collect the current fingerprint image of the user, extracting the fingerprint feature included in the current fingerprint image, and comparing the fingerprint feature with the reference fingerprint feature in the database.

Further, the present invention also needs to first perform database entry, that is, first collect the fingerprint image of the user, extract the fingerprint feature as the reference fingerprint feature, and save the reference fingerprint feature in the database, and the user who stores the fingerprint feature in the database is For security users, all functional applications are open to security users. If they are not secure users, they cannot be used for applications that require high-security fingerprint authentication. If a fingerprint verification command is received, the electronic device is set. The current mode is the security mode, and the fingerprint sensor is controlled to collect fingerprint images, pre-process the collected fingerprint images, extract the features required for fingerprint verification, and compare them with the reference fingerprint features pre-stored in the database, if the comparison If successful, the current user is a secure user for the current application and can switch the current mode to non-secure mode.

In this way, the fingerprint recognition feature extraction function is expanded, and the fingerprint sensor can be well utilized to implement more functions, and at the same time, the unique function of the user identification is ensured.

In a specific embodiment of the present invention, on the basis that the electronic device includes the security mode and the non-secure mode, the function of the direction key can be implemented by the fingerprint sensor in the non-secure mode, and the specific steps can be as shown in FIG. 3 .

Step S301, setting the current mode of the unlocked electronic device to the non-secure mode.

Step S302, if the current application is an application including a direction key indication, detecting a fingerprint touch The area of the fingerprint sensor sensing area. Among them, the application including the direction key indication includes at least a browser or an e-book.

Step S303, detecting a lateral direction of the area on the sensing portion of the sensor.

Step S304, issuing an instruction corresponding to the direction key function according to the direction of the focus. The direction key includes an up direction key, a down direction key, a left direction key, and a right direction key.

When an application such as a browser or an e-book is opened, a display button may be displayed on the display interface of the electronic device. When the fingerprint sensor detects that the fingerprint touches the sensing portion, the fingerprint sensor is controlled to detect the area touched by the fingerprint according to the change in capacitance. And detecting a direction of the contact area on the sensing portion, and issuing a command corresponding to the direction key function according to the direction of the focus, wherein the direction of the focus is specifically a direction in which the touch area accounts for the largest proportion of the sensing portion. For example, if the touch area is set to be on the upper side of the sensing portion, the command corresponding to the up direction key function is issued; when the touch area is focused on the lower side of the sensing portion, the function corresponding to the down direction key is issued. When the touch area is focused on the left side of the sensing part, the command corresponding to the left direction key function is issued; when the touch area is focused on the right side of the sensing part, the command corresponding to the right direction key function is issued.

It is also possible to preset a fingerprint specifying action corresponding to each direction key, and realize a function of moving in a corresponding direction according to a moving direction of the setting fingerprint. For example, it may be set to receive when the fingerprint is moved to the left in the sensing portion of the fingerprint sensor. The movement information sensed by the fingerprint sensor controls the function of the current application to move to the left.

In this way, the existing fingerprint sensor can be conveniently used to implement the function of the direction key, which saves the space of the direction key. At the same time, in the non-safe mode, fingerprint verification is not required, and the touch key can be realized by any fingerprint touch. The function is more convenient and simple.

In another embodiment of the present invention, on the basis of the above-mentioned electronic device including a safe mode and a non-secure mode, the function of the start key can be implemented by the fingerprint sensor in the non-secure mode, and the start key is generally used in the art. The start key is called the home key, and the specific steps can be as shown in FIG. 4.

In step S401, the current mode of the unlocked electronic device is set to the non-secure mode.

Step S402, detecting an area where the fingerprint touches the sensing portion of the fingerprint sensor in a normal environment.

Step S403, if the touch area exceeds the set area, the finger corresponding to the home key function is issued. make. The instruction corresponding to the home key function at least includes returning to the main interface.

For example, the set area may be, but not limited to, 60% of the total area of the sensing portion. Thus, when it is detected that the area of the sensing portion of the fingerprint touch fingerprint sensor exceeds 60% of the total area of the sensing portion, the corresponding home button is issued. Function instructions.

Further, if the area of the fingerprint sensor that touches the fingerprint sensor twice in a normal environment exceeds the set area, the instruction corresponding to the function of double-clicking the home button is issued, for example, the task manager can be opened, and the one-hand operation is switched. mode.

If, under normal circumstances, it is detected that the time when any fingerprint touches the fingerprint sensor exceeds the set time, for example, it may be 1 s, the instruction corresponding to the long press of the home key function is issued, for example, it may be a voice control function.

In this way, on the basis of realizing the function of the home key, the space of the home key is saved, and at the same time, since the fingerprint verification is not required, in the non-secure mode, the touch of any fingerprint can realize the function of the home key, which is more convenient and simple. .
