1) Terminal equipment, also called User Equipment (UE), is a device that provides voice and/or data connectivity to users, for example, a handheld device with a wireless connection function, a vehicle-mounted device, and the like. Common terminals include, for example, mobile phones, tablet computers, notebook computers, palmtop computers, mobile internet devices (mobile internet devices, MIDs), wearable devices, such as smart watches, smart bracelets, and pedometers.

2) The fingerprint identification module is to realize the identification of individual fingerprint characteristics through a specific sensing module. At present, fingerprint identification modules are mainly divided into optical fingerprint modules, capacitive fingerprint modules and radio frequency fingerprint modules. The fingerprint identification module can be set in combination with the dome button of the membrane key of the terminal device, and can be set on the front, back or side of the terminal device, which is not limited in the present invention. Similarly, the fingerprint recognition module can be combined with the touch screen of the terminal device, and can be set under the touch panel of the touch screen.

3), "Multiple" refers to two or more than two. "And/or" describes the association relationship of associated objects, indicating that there may be three types of relationships, for example, A and/or B may indicate: A exists alone, A and B exist simultaneously, and B exists independently. The character "/" generally indicates that the contextual objects are an "or" relationship.

Please refer to FIG. 1. FIG. 1 is a schematic flowchart of a touch unlocking method provided by an embodiment of the present invention, including the following steps:

S101. When detecting a user's touch and press operation on the fingerprint identification module of the terminal device, the terminal device acquires N fingerprint images, where N is an integer greater than 1, and the N fingerprint images are different from each other.

S102. The terminal device matches N fingerprint images in parallel with W registered fingerprint templates pre-stored in the terminal device respectively, where W is an integer greater than 1.

S103. If it is detected that one of the N fingerprint images matches one of the W registered fingerprint templates, the terminal device loads the target interface, and displays the target interface after the loading of the target interface is completed. .

In the above step S101, for example, assuming that the terminal device is a smart phone, the current smart phone can set multiple fingerprint templates, for example, 5 fingerprint templates can be set, and there may be more than 2 of the 5 fingerprint templates belonging to the same person. When the fingerprint is unlocked, the user can input N fingerprint images. For example, N fingers of the user perform touch and press operations on the fingerprint recognition module of the terminal device, and the fingerprint recognition module of the terminal device can collect N fingerprint images. It should be noted that when the user's N fingers press the fingerprint identification module at the same time, the fingerprint identification module can simultaneously collect N fingerprint images. When the user's N fingers press the fingerprint identification module successively, the fingerprint The identification module can collect N fingerprint images successively, and the present invention does not limit the time when N fingerprint images are acquired.

Optionally, referring to FIG. 2, the quotient of W divided by N is H, and H is an integer greater than or equal to 1. The specific implementation of the above step S102 can be as follows:

S102-a. The terminal device divides the W registered fingerprint templates into N groups of registered fingerprint templates, each of the N groups of registered fingerprint templates includes H registered fingerprint templates, and the N groups of registered fingerprint templates are different from each other.

S102-b. The terminal device matches the N fingerprint images with the N groups of registered fingerprint templates respectively in parallel.

For example, assuming that N=2, W=4, and H=2, the implementation of S102-a in the above steps is as follows: the terminal device first determines the priorities of the four registered fingerprint templates, assuming that the priority of the four registered fingerprint templates The relationship is: fingerprint template 1> fingerprint template 2> fingerprint template 3> fingerprint template 4, then the terminal equipment can be divided into 2 groups of registered fingerprint templates according to the priority: the first group of registered fingerprint templates includes fingerprint template 1 and fingerprint template 3, The second group of registered fingerprint templates includes fingerprint template 2 and fingerprint template 4 . The implementation of S102-a of the above steps can also be as follows: the terminal device first determines the sharpness of the two fingerprint images, assuming that the sharpness relationship between the two fingerprint images is that fingerprint image 1 is greater than fingerprint image 2, because the first group of registered fingerprint templates The priority is relatively higher than that of the second group of registered fingerprint templates. The terminal device can pair fingerprint image 1 with the first group of registered fingerprint templates, and fingerprint image 2 with the second group of registered fingerprint templates, and then the terminal device will pair the paired two The fingerprint image is matched one by one with the two registered fingerprint templates in parallel. Of course, the implementation of S102-a in the above steps includes: the terminal device randomly pairs two fingerprint images with two sets of registered fingerprint templates, for example, fingerprint image 1 is paired with the second set of registered fingerprint templates, and fingerprint image 2 is paired with the first set of fingerprint templates. The registered fingerprint templates are paired, and then the terminal device matches the paired 2 fingerprint images with 2 groups of registered fingerprint templates in parallel.

It should be noted that since the two sets of registered fingerprint templates both contain two registered fingerprint templates, the terminal device can perform round-robin matching according to the order of priority when matching, and of course it can also be randomly matched.

Optionally, please refer to Fig. 3, the quotient of W divided by N is K and the remainder M, K and M are both integers greater than or equal to 1, the specific implementation of the above step S102 can have:

S102-c, the terminal device divides the W registered fingerprint templates into N groups of registered fingerprint templates, each of the M groups of registered fingerprint templates in the N groups of registered fingerprint templates contains K+1 registered templates, and N-M groups of registered fingerprint templates Each group in contains K registered fingerprint templates, and the N groups of registered fingerprint templates are different from each other.

S102-d. The terminal device matches the N fingerprint images with the N groups of registered fingerprint templates respectively in parallel.

For example, assuming W=5, N=2, K=2, M=1, the implementation of S102-c in the above steps is as follows: the terminal device first determines the priority of the four registered fingerprint templates, assuming that the four registered fingerprint templates The priority relationship of the templates is: fingerprint template 1 > fingerprint template 2 > fingerprint template 3 > fingerprint template 4, then the terminal equipment can be divided into 2 groups of registered fingerprint templates according to the priority: the first group of registered fingerprint templates includes fingerprint template 1, Fingerprint template 3 and fingerprint template 5, the second group of registered fingerprint templates includes fingerprint template 2 and fingerprint template 4. The implementation of S102-d of the above steps can also be as follows: the terminal device first determines the sharpness of the two fingerprint images, assuming that the sharpness relationship between the two fingerprint images is that fingerprint image 1 is greater than fingerprint image 2, because the first group of registered fingerprint templates The priority includes 3 fingerprint templates and has the highest priority fingerprint template. The terminal device can pair the high-resolution fingerprint image 1 with the first group of registered fingerprint templates, and the relatively low-resolution fingerprint image 2 with the second group of registered fingerprint templates. The fingerprint templates are paired, and then the terminal device matches the paired 2 fingerprint images with 2 sets of registered fingerprint templates in parallel. Of course, the implementation of S102-d in the above steps includes: the terminal device randomly pairs two fingerprint images with two sets of registered fingerprint templates, for example, fingerprint image 1 is paired with the second set of registered fingerprint templates, and fingerprint image 2 is paired with the first set of fingerprint templates. The registered fingerprint templates are paired, and then the terminal device matches the paired 2 fingerprint images with 2 groups of registered fingerprint templates in parallel.

It should be noted that since both groups of registered fingerprint templates contain 2 or 3 registered fingerprint templates, when matching, the terminal device can perform round-robin matching according to the order of priority, of course, random matching can also be used.

Optionally, please refer to FIG. 4, N is greater than W, and the specific implementation manner of the above step S102 may include:

S102-e. The terminal device determines the sharpness of the N fingerprint images, and selects the top W fingerprint images with the highest sharpness from the N fingerprint images.

S102-f. The terminal device matches the W fingerprint images with the W registered fingerprint templates respectively in parallel.

For example, assuming that N=4 and W=2, the implementation of the above step S102-e is as follows: the terminal device first determines the image sharpness of the four fingerprint images, assuming that the sharpness relationship of the four fingerprint images is: fingerprint image 1 >fingerprint image 2>fingerprint image 3>fingerprint image 4, then the selected W fingerprint images include fingerprint image 1 and fingerprint image 2. The implementation of the above step S102-f includes: the terminal device can pair the priorities of the two registered fingerprint templates according to the clarity of the selected two fingerprint images, for example, the priority relationship of the two registered fingerprint templates is: register Fingerprint template 1 > registered fingerprint template 2, the terminal device can pair the fingerprint image 1 with high resolution with the registered fingerprint template 2 with low priority, and the fingerprint image 2 with low resolution can be paired with the registered fingerprint template 1 with low priority, and then The terminal device matches the paired two fingerprint images with the two registered fingerprint templates one by one in parallel.

Optionally, the specific implementation manners of the above step S103 are:

The terminal device determines whether the N fingerprint images have bound applications;

If X fingerprint images in the N fingerprint images have bound applications, the terminal device loads the main interface of the application bound to one of the X fingerprint images, where X is an integer greater than or equal to 1;

If there is no bound application in the N fingerprint images, the terminal device loads the main interface of the application that was running when the terminal device locked the screen last time.

For example, assuming that N=2 and X=2, the terminal device loads one of the two fingerprint images into the main interface of the application bound with the fingerprint image. The specific implementation method may be as follows: the terminal device determines the 2 The number of times an application is started within a preset period (such as the current system time ± 30 minutes), assuming that the relationship between the number of times that two applications corresponding to two fingerprint images are started within a preset period is Application 1 > Application 2, then the terminal The device loads the main interface of application 1. Certainly, the specific implementation manner of loading the main interface of the application bound with one of the two fingerprint images by the terminal device may also randomly load the main interface of one of the two applications. It should be noted that the interface on which the terminal device loads the application may not be the main interface, may be a preset interface, or may be the interface on which the application was run last time, and so on.

Optionally, the target interface loaded in the above step S103 may be a system desktop, a predefined interface, and the like.

Optionally, after the above step S103, the method shown in FIG. 1 further includes:

If the type of the target interface is a preset type, the terminal device acquires the current geographic location of the terminal device;

The terminal device displays service information associated with the current geographic location.

Wherein, the preset type is a service type, and the service type includes but not limited to food, KTV, leisure and entertainment, movies and so on. For example, assuming that the target interface corresponds to a gourmet interface, when the current geographic location of the terminal device is a restaurant, the terminal device can obtain service information about the restaurant, such service information can be preferential information, menus, etc., and then the terminal The device displays the acquired service information on the display screen of the terminal device for the user to view.

Optionally, after the above step S103, the method shown in FIG. 1 further includes:

The terminal device obtains the current ambient brightness;

The terminal device adjusts the screen brightness of the terminal device according to the current ambient brightness.

For example, after the terminal device loads the target interface, the terminal device can sense the surrounding ambient brightness through the terminal device's light sensor, and then the terminal device adjusts the appropriate The screen brightness of the current ambient brightness to achieve the effect of protecting the eyes.

Optionally, the specific implementation manners of acquiring N fingerprint images by the terminal device in step S101 above include:

The sensing electrodes of the fingerprint identification module of the terminal device obtain N normal bottom data sets and N abnormal bottom data sets, wherein the N normal bottom data sets correspond to the N abnormal bottom data sets one by one, and the N Each of the normal underlying data sets includes a plurality of normal underlying data values, and each of the N abnormal underlying data sets includes a plurality of abnormal underlying data values;

The terminal device determines N target low-level data sets corresponding to the N abnormal low-level data sets according to the N normal low-level data sets, and the N sets of abnormal low-level data sets are in one-to-one correspondence with the N sets of target low-level data sets;

The terminal device generates N fingerprint images according to the N normal low-level data sets and the N target low-level data sets.

In addition, in the above example process, an example implementation process in which the terminal device determines the N target underlying data sets corresponding to the N abnormal underlying data sets according to the N normal underlying data sets is as follows:

The terminal device determines N average values according to a plurality of normal underlying data values included in the N normal underlying data sets, and the N average values correspond to the N normal underlying data sets one-to-one;

The terminal device replaces the plurality of abnormal underlying data contained in the N abnormal underlying data sets with the N average values, so as to obtain N target underlying data sets corresponding to the N abnormal underlying data sets, the The N abnormal underlying data sets are in one-to-one correspondence with the N average values.

The aforementioned underlying data values may include capacitance and/or voltage and the like. The above-mentioned abnormal sensing electrodes are sensing electrodes with abnormalities in the fingerprint collection area. The sensing electrodes of the fingerprint recognition module can be detected by the MCU of the fingerprint recognition module.

It should be noted that as the usage time of the fingerprint recognition module increases, some of the sensing electrodes of the fingerprint recognition module will become abnormal, and the underlying data obtained by these abnormal sensing electrodes will be abnormal, which will cause the terminal The fingerprint image generated by the device from the underlying data acquired by normal sensing electrodes and abnormal sensing electrodes has noise, which affects the contrast of subsequent fingerprint comparisons. Therefore, before generating fingerprint images, these abnormal underlying data can be corrected to reduce fingerprints. Image noise, which in turn can improve the contrast of fingerprint contrast.

It should be noted that if the sensing electrode array of the fingerprint module includes M1 normal sensing electrodes and M2 abnormal sensing electrodes, if N fingerprint images are acquired one by one (for example, multiple fingers of the user press the fingerprint recognition module one by one), In this case, each of the N normal underlying data sets contains M1 normal underlying data values, and each of the N abnormal underlying data sets contains M2 abnormal underlying data values. If the N fingerprint images are simultaneously Acquired (for example, the fingerprint identification module is combined with the touch screen setting, and the user presses the touch screen of the terminal device with multiple fingers at the same time), in this case, the multiple normal underlying data contained in each of the N normal underlying data sets can be the same may also be different, and not equal to M1, and each of the N abnormal underlying data sets contains abnormal underlying data values, which may be the same or different, and not equal to M2.

Compared with the prior art, which polls a single fingerprint image and matches it with the W registered fingerprint templates pre-stored in the terminal device, the solution provided by the present invention can input multiple fingerprint images, and then parallelize the multiple fingerprint images with the The W registered fingerprint templates pre-stored in the terminal device are matched, and the fingerprint matching takes a shorter time, thereby speeding up the fingerprint unlocking speed.

The embodiment of the present invention also provides another more detailed method flow, as shown in Figure 5, including:
