All the above-mentioned optional technical solutions can be combined arbitrarily to form optional embodiments of the present disclosure, which will not be repeated here.

Fig. 2A is a flowchart of a method for enabling a function according to an exemplary embodiment, as shown in Fig. 2A, applied to a terminal, including the following steps:

In step 201, when it is detected that the physical button is pressed, fingerprint collection is performed in the fingerprint identification area corresponding to the physical button to obtain first fingerprint information.

In the embodiment of the present disclosure, the terminal can activate the corresponding preset function according to the pressing operation of the physical button. In order to ensure the security of the terminal and prevent other users from illegally operating the terminal, the physical button and the fingerprint recognition function can be combined in the At the same time, the terminal can perform fingerprint recognition to enable the preset function while detecting the pressing operation on the physical key.

The physical keys may be a Home key, a power key, a volume key, etc. of the terminal, which are not specifically limited in this embodiment of the present disclosure. The preset function corresponding to the physical button may be: terminal unlocking function, or converting the terminal screen from the off-screen state to the bright-screen state, or returning the current screen interface from the application interface to the desktop, or displaying the desktop homepage, etc., the embodiments of the present disclosure This is not specifically limited. The preset function may be preset or modified by the terminal or the user, and the preset function may be a built-in function of the system, or a function of installing an application on the terminal, etc., which is not specifically limited in this embodiment of the present disclosure.

Taking the physical key as the Home key as an example, the structure shown in FIG. 2B is generally used to realize the combination of the physical key and the fingerprint identification function. In FIG. 2B , the fingerprint identification sensor is arranged above the physical button, and the area corresponding to the upper surface of the fingerprint identification sensor is the fingerprint identification area. The fingerprint identification sensor is used for fingerprint identification in the fingerprint identification area. When the physical key is not pressed, the upper surface of the fingerprint recognition sensor is flush with the upper surface of the cover glass, and the position where the physical key is located at this time is called the original position. The user can trigger the pressing of the physical button by pressing the fingerprint recognition sensor, and at this time, the physical button moves downward from the original position.

In the embodiment of the present disclosure, the process of the user pressing the physical key includes a pressing process and a lifting process of the physical key. In the prior art, the terminal can only perform fingerprint recognition when the physical button is lifted and restored to the original position, which leads to a long time for function activation. Therefore, in order to shorten the time consumption of the preset function activation process, the terminal When it is detected that the physical button is pressed, a fingerprint is collected in the fingerprint identification area corresponding to the physical button, and the collected fingerprint is identified. For the specific identification process, refer to step 202 . In the embodiment of the present disclosure, the fingerprint information collected when the physical key is pressed is referred to as the first fingerprint information.

In step 202, the first fingerprint information is matched with at least one stored fingerprint template to obtain a first matching result, if the first matching result is that the matching is successful, go to step 203, and if the first matching result is that the matching fails, go to step 203 204.

The terminal can store at least one fingerprint template, which can be used to indicate the fingerprints of the same finger or the fingerprints of different fingers, and each fingerprint template has a unique template identifier for identifying the fingerprint template. The template identifier may be automatically generated by the terminal, and may also be set or modified by the user, which is not specifically limited in this embodiment of the present disclosure. Wherein, each fingerprint template can be generated by the terminal according to multiple fingerprint entry operations of the user. Specifically, the user can repeatedly place the finger in the fingerprint identification area, so that the terminal can collect multiple fingerprint information in the fingerprint identification area, and then generate a fingerprint template according to the collected multiple fingerprint information. The user does not need to press the finger when placing the finger in the fingerprint recognition area, so that the finger will not be deformed. That is, the fingerprint template stored in the terminal corresponds to an undeformed fingerprint.

Specifically, the terminal identifies the first fingerprint information according to the at least one fingerprint template, that is, matches the first fingerprint information with the stored at least one fingerprint template. The process may be: the terminal matches the at least one fingerprint information according to the first fingerprint information The similarity of each fingerprint template in the template is used to determine whether there is a target fingerprint template in at least one fingerprint template. The target fingerprint template is a fingerprint template whose similarity with the first fingerprint information exceeds a preset threshold. If the target fingerprint template exists in at least one fingerprint template, it is determined that the matching is successful; if the target fingerprint template does not exist in at least one fingerprint template, it is determined that the matching fails.

The preset threshold may be preset or modified by the terminal, which is not specifically limited in this embodiment of the present disclosure. The similarity between the first fingerprint information and the fingerprint template refers to the percentage of the partial fingerprint information included in the fingerprint template in the first fingerprint information to the first fingerprint information. For example, if 80% of the fingerprint information in the first fingerprint information is included in the fingerprint template, the similarity between the first fingerprint information and the fingerprint template is 80%. Of course, the above similarity can also be calculated by other algorithms, which is not specifically limited in this embodiment of the present disclosure

It should be noted that, in order to reduce the calculation amount of fingerprint identification and shorten the time-consuming of fingerprint identification, in the process of fingerprint identification, the terminal may not match the first fingerprint information with each fingerprint template, but in the matching process. In the process, once it is found that the similarity between a certain fingerprint template and the first fingerprint information exceeds a preset threshold, the fingerprint template is determined as the target fingerprint template, and the fingerprint identification process is ended.

In step 203, if the first matching result is that the matching is successful, the preset function is enabled, and the process of enabling the preset function is ended.

The preset function may be a terminal unlocking function, a camera function, a payment function, etc. When the preset function is a terminal unlocking function, enabling the preset function refers to unlocking the terminal. It is assumed that the description method of the function is not used to limit the general description method for enabling the function in practical applications. For example, the general description method for enabling the terminal unlocking function is to unlock the terminal.

In another embodiment, when a physical key is pressed, a deformed fingerprint may be collected, and the fingerprint template stored in the terminal corresponds to an undeformed fingerprint. Therefore, when the first fingerprint information collected when the physical key is pressed, the identification may fail. In this case, in order to collect an undeformed fingerprint and perform fingerprint identification to improve the success rate of fingerprint identification, when the first matching result is a matching failure, the terminal may restore the physical button to the original position after detecting that the , the fingerprint identification is performed again, and the process is detailed in step 204. In this way, the user's finger is still placed in the fingerprint recognition area when the physical button is lifted. Therefore, in order to cultivate the user's usage habit and ensure the success rate of the function opening, when the terminal determines that the first matching result is a successful match, The result of successful matching is recorded first, and when it is detected that the physical key is restored to the original position, the result of successful matching is returned to enable the preset function. In this way, the user is guided to keep the finger in the fingerprint identification area during the process of lifting the physical button, so that when the first matching result is a matching failure, the second fingerprint identification process can be successfully performed. The process is to complete the fingerprint recognition and record the recognition result when the physical button is pressed, and return the matching result directly after the physical button is lifted to enable the preset function, and only perform fingerprint recognition after the physical button is lifted, so as to Compared with the process of turning on the preset function, the time for turning on the function is shortened, and the efficiency of turning on the function is improved.

In step 204, if the first matching result is that the matching fails, when it is detected that the physical key is restored to the original position, fingerprint collection is performed in the fingerprint identification area to obtain second fingerprint information.

In order to improve the success rate of fingerprint recognition, and thus improve the success rate of enabling the preset function, when the first matching result is that the matching fails, the terminal can also check the undeformed shape in the fingerprint recognition area when the physical button is restored to the original position. The fingerprint is collected once to obtain the second fingerprint information, and then the collected fingerprint is identified. For the specific identification process, refer to step 205 .

In another embodiment, in the process of fingerprint recognition, the finger placed in the fingerprint recognition area may not be the finger indicated by the fingerprint template at all. In this case, no matter how many times the fingerprint recognition is performed, it may not be recognized successfully. . Therefore, in order to simplify the opening process of the preset function and reduce the power consumption caused by unnecessary fingerprint identification, the terminal may not execute the steps when the similarity between the first fingerprint information and each fingerprint template is less than the minimum similarity threshold 204. That is, when the first matching result is that the matching fails, the terminal does not need to perform the secondary identification of the fingerprint, nor does it need to perform the collection of the second fingerprint information. Specifically, in step 202, the terminal can obtain the similarity between the first fingerprint information and each stored fingerprint template, and if each obtained similarity is less than the minimum similarity threshold, it means that the collected first fingerprint information It is very different from the stored fingerprint template, and it is impossible to recognize successfully even if the finger is not deformed. The minimum similarity threshold may be preset or modified by the terminal, which is not specifically limited in this embodiment of the present disclosure.

In step 205, the second fingerprint information is matched with at least one fingerprint template to obtain a second matching result. If the second matching result is successful, go to step 206, and if the second matching result is unsuccessful, go to step 208.

In this step, the process of performing fingerprint identification on the second fingerprint information is the same as the process of identifying the first fingerprint information in the foregoing step 202, and details are not repeated here.

In step 206, if the second matching result is that the matching is successful, the preset function is enabled.

When the physical button is restored to the original position, after the terminal detects that the fingerprint identification is successful, the terminal determines the preset function associated with the physical button, and enables the preset function. For example, when the preset function is the terminal unlocking function, the terminal is unlocked; when the preset function is the payment function, the payment page corresponding to the payment function is opened, and the like.

In step 207, a target fingerprint template is determined, and the target fingerprint template is updated according to the second fingerprint information.

Wherein, the target fingerprint template is a fingerprint template whose similarity with the second fingerprint information exceeds a preset threshold.

In the process of generating a fingerprint template, the terminal collects a limited number of fingerprints, so that the fingerprint template may not completely contain all the fingerprint information of the finger. For example, the fingerprint template only contains the partial fingerprint information of the finger. In the process of enabling the preset function, the collected fingerprint information may not be completely the same as the fingerprint information in the fingerprint template. If the similarity between the collected second fingerprint information and the target template is 90%, it means that 90% of the second fingerprint information is the same as the fingerprint information indicated by the target fingerprint template, and the remaining 10% of the fingerprint information Then it is different from the fingerprint information indicated by the target fingerprint template, and the 90% fingerprint information can be called the same fingerprint information, and the 10% fingerprint information can be called the difference fingerprint information.

Therefore, in order to expand the amount of fingerprint information indicated by the fingerprint template, thereby improving the accuracy of fingerprint identification, the terminal can update the fingerprint template according to the second fingerprint information, and the specific process includes but is not limited to the following two ways:

1. The terminal can extract differential fingerprint information from the second fingerprint information that is different from the target fingerprint template, and update the differential fingerprint information to the target fingerprint template.

The method of updating the differential fingerprint information into the target fingerprint template may include: when the differential fingerprint information is not included in the target fingerprint template at all, that is, when the similarity between the differential fingerprint information and the target template is 0, changing the The differential fingerprint information is directly added to the target fingerprint template. Or, when the similarity between the difference fingerprint information and the target template is not 0, in the target fingerprint template, the part similar to the difference fingerprint information is replaced with the difference fingerprint information.

2. The terminal obtains the same fingerprint information of the target fingerprint template and the second fingerprint information from the target fingerprint template, and replaces the same fingerprint information with the second fingerprint information.

It should be noted that, step 207 is a process of updating the target fingerprint template according to the undeformed second fingerprint information. In the example of the present disclosure, since the fingerprint template stored in the terminal corresponds to the undeformed fingerprint information, in order to ensure the quality of the fingerprint template, the undeformed second fingerprint information is used to update the fingerprint template instead of the possibly deformed fingerprint information. The first fingerprint information of the fingerprint template is updated.

In step 208, if the second matching result is a matching failure, the number of matching failures is recorded, and when the number of matching failures reaches a preset number of times, the preset function is locked.

The preset number of times may be preset by the terminal, or preset or modified by the user according to actual needs, which is not specifically limited in this embodiment of the present disclosure.

In order to improve the security of the terminal and prevent illegal use of the terminal by other users, when the second matching result is a matching failure, the terminal can also record the number of matching failures, and when the number of matching identifications reaches a preset number of times, the preset function to lock. When the preset function is in the locked state, the terminal does not respond to any operation of the preset function within the first preset time, such as an opening operation, an uninstalling operation, an icon moving operation, and the like. The first preset time may be preset or modified by the terminal, which is not specifically limited in this embodiment of the present disclosure.

In addition, in order to further improve the security of the terminal, the terminal can also record the number of times the preset function is locked within the second preset time. Then, the terminal is locked, that is, the terminal does not respond to any operation of the user, such as a touch operation, a power key operation, etc., which is not specifically limited in this embodiment of the present disclosure. The second preset time is not less than the first preset time, and can be preset or modified by the terminal, which is not specifically limited in this embodiment of the present disclosure.

Taking the preset function as the terminal unlocking function as an example, the above process from step 201 to step 208 will be explained. Assuming that when the terminal is in the screen-locked state, the screen is in the off-screen state, then refer to FIG. 2C for the opening process of the terminal unlocking function Figure, including the following:

Step a. When the terminal detects that the physical button is pressed, the screen is turned on, that is, the screen is converted from the off-screen state to the bright-screen state, and fingerprints are collected in the fingerprint identification area to obtain the first fingerprint information.

Step b. Match the first fingerprint information with the stored fingerprint template. If the matching is successful, after the physical button is lifted, that is, when the physical button is restored to the original position, the terminal is unlocked, and the fingerprint template is not updated. .

Step c. If the matching fails, after the physical button is lifted, a second fingerprint collection is performed in the fingerprint identification area to obtain the second fingerprint information.

Step d, match the second fingerprint information with the stored fingerprint template, if the matching is successful, unlock the terminal, and update the fingerprint template according to the second fingerprint information.

Step e. If the matching fails, the device will not be unlocked, and the number of matching failures will be recorded, and the fingerprint template will not be updated at this time.

In step d, the number of matching failures reaches a preset number, and the terminal is locked in a locked screen state.

In the method provided by the embodiments of the present disclosure, during the process of pressing the physical button, the fingerprint collection is performed in the fingerprint recognition area when the physical button is pressed, and the fingerprint recognition is performed, so that the physical button can be restored to the original position. The opening of the function shortens the time-consuming process of opening the function and improves the efficiency of opening the function. Further, when the first fingerprint recognition fails, the terminal can also perform the second fingerprint collection and recognition when the physical button is restored to the original position, and after the fingerprint recognition succeeds, the corresponding function can be turned on, which improves the function. success rate of opening.
