technical field

The invention relates to the technical field of computers, and in particular, to a fingerprint unlocking control method and a mobile terminal.

Background technique

The fingerprint image is the data of the fingerprint with the image form as the carrier. Fingerprints are lines formed by bumpy skin on the end of human fingers. Fingerprints can increase the friction of the hand when it touches an object, making it easier to exert force and grasp the object. It is naturally formed in the process of human evolution. Fingerprints are the lines formed by the bumpy skin on the finger pulp at the end of human fingers. Since human fingerprints are a combination of genetics and the environment, they are also closely related to human health. Therefore, everyone has fingerprints, but they are different. The repetition rate of fingerprints is extremely small, about one in 15 billion, so it is called "human ID card". It is based on this feature of fingerprints that fingerprints are widely used as information for identity authentication.

For example, fingerprint recognition technology has become the standard configuration of flagship models of mainstream mobile terminal manufacturers. Fingerprint recognition can not only be used for functions such as unlocking and waking up mobile terminals, but also an important part of mobile payment.

The time required for the mobile terminal to read the fingerprint image until the screen is illuminated is called the black screen unlocking time.

The speed of the black screen unlocking time directly affects the efficiency of the user's use of the device. How to shorten the black screen unlocking time and improve the unlocking efficiency has become an important research direction for technicians.

In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. . Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

An embodiment of the present invention provides a fingerprint unlocking control method, as shown in FIG. 1 , including:

101: Monitor the environmental status information of the mobile terminal when the mobile terminal is in a black screen state;

In the embodiment of the present invention, the environmental state information is mainly the information of the surrounding environment change of the mobile state and its own motion state, which is used to determine whether the user may have the need to light up the screen; in real life, if the user is far away from the mobile terminal, Or the mobile phone is in the pocket, or the user is in the process of hiking, running, etc., the user is unlikely to turn on the screen to use the mobile phone; while others may have the need to use the mobile phone relative to these changes; for example: If the user picks up the mobile phone, takes out the mobile phone from the pocket, or finishes exercising, etc., if the changes of these environmental state information can be monitored, the user's demand for using the mobile phone can be predicted, that is, the need for fingerprint unlocking. Such motion information may be obtained through, for example, a distance sensor, a position sensor, a gravity sensor, and the like, and details on how to obtain such information will not be repeated in this embodiment of the present invention.

102: Predict whether there is a fingerprint unlocking requirement based on the above environmental state information, and pre-start the power management service if it is predicted that there is a fingerprint unlocking requirement;

Based on the above description, the user's demand for using the mobile phone can be predicted based on the change of the environmental state information; the power management service is a functional module used for power control in the operating system, and lighting the screen may involve loading the driver required for the startup screen. Programs, power control and other aspects; the embodiment of the present invention does not focus on how the power management service starts the screen, so it will not be described in detail here.

103: Receive the fingerprint data and use the fingerprint data to compare with the registered fingerprint, and control the lighting of the screen through the power management service after the comparison is passed.

The registered fingerprint is the fingerprint data stored locally in the mobile terminal, and is used for comparison with the fingerprint data input by the user to determine whether the fingerprint data input by the user is the same as the registered fingerprint; the registered fingerprint is used for unlocking the black screen in this embodiment. The fingerprint used, the registered fingerprint may also be the registered fingerprint of the application in the mobile terminal.

In the embodiment of the present invention, since the power management service has been pre-started before the fingerprint data is acquired, the startup process of the power management service can be processed in parallel with the fingerprint collection device and the fingerprint comparison process, which can save time in fingerprint comparison. After the comparison is completed and it is determined that the comparison is passed, it is necessary to wait for the time for the power management service to start, so the time for unlocking the black screen can be shortened, thereby improving the efficiency of fingerprint unlocking.

In addition, the embodiment of the present invention also provides a specific implementation scheme for predicting whether there is a fingerprint unlocking requirement based on the environmental status information of the mobile terminal, as follows: the above-mentioned monitoring of the environmental status information of the mobile terminal; include:

Monitoring whether there is an object close to the fingerprint collection device of the mobile terminal, if there is an object close to the fingerprint collection device, it is determined that there is a need for fingerprint unlocking;

Or, monitor the motion state information of the above-mentioned mobile terminal, if it is determined that the above-mentioned mobile terminal is picked up from a standstill according to the above-mentioned motion state information, it is determined that there is a fingerprint unlocking requirement, or, if it is determined according to the above-mentioned motion state information that the motion speed of the above-mentioned mobile terminal is from If the change from high to low is higher than the predetermined threshold and the movement speed is lower than the threshold, it is determined that there is a need for fingerprint unlocking.

Based on the foregoing description, it can be understood that other environmental state information of the mobile terminal may be used to predict whether there is a fingerprint unlocking requirement, so the examples of the embodiments of the present invention should not be construed as unique limitations of the embodiments of the present invention.

Further, after pre-starting the power management service, energy consumption will increase and the fingerprint unlocking requirement is a prediction result that may not be accurate every time. In order to save possible waste of energy consumption, the embodiment of the present invention provides the following solutions: After the above-mentioned pre-starting the power management service, the above-mentioned method further includes:

If the fingerprint data is not received within a predetermined period of time, the above-mentioned power management service is hibernated.

The above predetermined time period can be set based on experience. For example, when the user takes out the mobile phone from his pocket and the screen is unlocked within 10S, the predetermined time period can be set to 10S, or a little longer; other applications The scenarios are deduced in the same way; the specific value of the predetermined time period is not uniquely limited in this embodiment of the present invention. By adopting the solution of this embodiment, the technical effect of reducing energy consumption can be achieved.

In addition, the embodiments of the present invention further provide other technical solutions for accelerating the fingerprint unlocking speed, as follows: after the fingerprint unlocking demand is predicted as described above, the above method further includes:

The response speed of the fingerprint collection device of the mobile terminal is improved based on the initial state; if no fingerprint data is received within a predetermined time period, the response speed of the fingerprint collection device of the mobile terminal is restored to the initial state.

Improving the response speed of the fingerprint collection device is based on the response speed of the fingerprint collection device in the initial state as a standard; the specific improvement method may be to increase the clock frequency of the processor and/or increase the fingerprint collection frequency of the fingerprint collection device, etc. Various technical indicators related to the response speed of the fingerprint collection device, etc., can improve the response speed of the fingerprint collection device, thereby improving the speed of fingerprint collection of mobile terminals in a short time, thereby shortening the fingerprint unlocking time.

In addition, it can be understood that increasing the response speed of the fingerprint collection device may be accompanied by high energy consumption in a short period of time. In order to reduce the energy consumption level of the mobile terminal, the response of the fingerprint collection device will be restored within a predetermined period of time. speed, so that the energy consumption of the mobile terminal is reduced.

Based on the above introduction, the motion state information can relatively determine that the user does not need to use the mobile phone, that is, there is no need for fingerprint unlocking, then in this case, some power consumption control can be done, as follows: When monitoring the above-mentioned mobile terminal After the environment state information, the above method further includes:

The motion state information of the above-mentioned mobile terminal is monitored, and if the above-mentioned motion state information is that the above-mentioned mobile terminal is in a stationary state, or, the above-mentioned motion state information is higher than a predetermined speed or acceleration, then reduce the response speed of the above-mentioned fingerprint collection device to be lower than initial state.

It can be understood that, in addition to reducing the response speed of the fingerprint collection device, if the current mobile terminal has other power-consuming items being executed, it can also be considered to reduce the power consumption occupied by the mobile terminal without affecting the necessary standby function of the mobile terminal. .

The embodiments of the present invention further provide an implementation scheme for improving fingerprint unlocking efficiency, which is specifically as follows: before using the above-mentioned fingerprint data to compare with the registered fingerprint, the above-mentioned method further includes:

Obtain the current location information of the above-mentioned mobile terminal;

Determine the security level corresponding to the above-mentioned current location information, and then determine the fingerprint unlocking level corresponding to the above-mentioned security level; the higher the above-mentioned security level, the lower the algorithm complexity corresponding to the above-mentioned fingerprint unlocking level;

The above-mentioned comparison using the above-mentioned fingerprint data with the registered fingerprint includes:

The above-mentioned fingerprint data is compared with the above-mentioned registered fingerprint through the above-mentioned fingerprint unlocking level corresponding algorithm.

In this embodiment, the current location information of the mobile terminal may be the geographic coordinate location information where the mobile terminal is located, or may be based on the geographic location information of the mobile terminal indicating that the mobile terminal is located in the user's residence, office, or any other location that is often Areas, which do not deviate from the areas commonly used by users, are generally safer.

Based on the above description, the location of the mobile terminal is related to its security. If it is a place where the user often goes, such as the user's home, then the use environment where the mobile terminal is located is relatively safe. In this case, it can be appropriately reduced. The security level of fingerprint unlocking, namely: lowering the fingerprint unlocking level, lowering the fingerprint unlocking level. Correspondingly, a fingerprint unlocking algorithm with lower complexity can be used, for example, using less fingerprint feature comparison, or in the fingerprint image comparison process If a lower proportion of the same fingerprint features are obtained in the middle, the authentication is determined to be passed.

Since the unlocking method corresponding to the fingerprint unlocking registration is used, in the case of a higher security level, an algorithm with lower complexity is used, so the speed of fingerprint unlocking will be improved. The above fingerprint unlocking method corresponds to an algorithm with a certain complexity, and the algorithm is used to compare the above fingerprint data with the registered fingerprint when the fingerprint is unlocked.

In this embodiment, it is determined whether the mobile terminal is currently in a relatively safe environment through the location information of the mobile terminal; if it is in a relatively safe environment, the security level of fingerprint unlocking can be lowered, and the corresponding selection complexity is relatively low. A small fingerprint unlocking algorithm is used to shorten the time required for fingerprint unlocking; therefore, the fingerprint unlocking efficiency can be improved on the premise of ensuring the security of the mobile terminal.

The embodiment of the present invention also provides a specific implementation scheme of how to determine the security level corresponding to the location information: before obtaining the current location information of the mobile terminal, the method further includes:

Counting the historical location information of the above-mentioned mobile terminal, and recording the location information with a higher frequency of occurrence in the historical location information, the corresponding security level is higher;

Alternatively, the location information setting information is received, and the location information setting information includes the location information and the security level corresponding to the location information.

Among the above two methods of determining the security level corresponding to the location information, the former method is automatically completed by using machine learning. After the historical location information is accumulated, the security level corresponding to the location information can be determined more accurately, which is both accurate and convenient. In one way, the user can set which specific locations are considered safe locations, which better reflects the user's subjective cognition and is more applicable to some specific users. The above two implementation methods are both to determine that certain geographical locations are considered to be relatively safe application environments, and accordingly a fingerprint unlocking algorithm with lower complexity can be used; if other methods are used to achieve the technical purpose, it will not affect the The implementation of the embodiments of the present invention, therefore, the above examples should not be construed as unique limitations on the embodiments of the present invention.

The embodiments of the present invention perform necessary pre-operations in advance based on pre-judging the fingerprint unlocking requirement before the fingerprint unlocking requirement, thereby improving the fingerprint unlocking efficiency.

One of the application scenarios is that in the black screen state, if the mobile phone is detected to be picked up, the response speed of the fingerprint acquisition device is improved; (for example, the frequency of fingerprint acquisition is increased, etc.); and the PMS is notified to pre-start, and then the fingerprint data is obtained. After the data, the fingerprint collection device can be restored to the initial response speed; the fingerprint data is compared with the registered fingerprint; the screen will be turned on if it passes, otherwise it will refuse to light up.

Another application scenario is that in the black screen state, adding a hand-held sensor to determine the user's mobile phone is picked up; combined with the user's actual unlocking scenario, it can be seen that the PMS can be turned on when the mobile phone is detected, and the PMS is turned on and continues to pre-order. Set the duration, such as 10 seconds, if the user's touch and pressing operation on the fingerprint collection device is not detected within the 10 seconds, the PMS will be put to sleep. In this way, the unlocking speed can be improved.

Another application scenario is that the probability of unlocking the mobile phone is small when the user is running, mountain climbing, etc., but during the period of recovery from a relatively intense exercise state to a relatively stable static state, the probability of unlocking the mobile phone to view various messages is relatively high. Based on this, it can be as follows: Detect the motion parameters such as the acceleration of the mobile phone; when it is detected that the motion parameters in the two or two time periods before and after the decrease are larger than the preset threshold, the PMS is enabled in advance; when the fingerprint identification authentication result is passed , notifies PMS to light up the screen, corresponding to loading the main interface, and by enabling the PMS service in advance, the unlocking speed can be improved.

The processor 701 is configured to monitor the environmental status information of the mobile terminal when the mobile terminal is in a black screen state; predict whether there is a fingerprint unlocking requirement based on the environmental status information, and pre-start the power supply if the fingerprint unlocking requirement is predicted Management service; receive fingerprint data and use the above fingerprint data to compare with the registered fingerprint, and control the lighting screen through the above power management service after the comparison is passed.

In the embodiment of the present invention, the environmental state information is mainly the information of the surrounding environment change of the mobile state and its own motion state, which is used to determine whether the user may have the need to light up the screen; in real life, if the user is far away from the mobile terminal, Or the mobile phone is in the pocket, or the user is in the process of hiking, running, etc., the user is unlikely to turn on the screen to use the mobile phone; while others may have the need to use the mobile phone relative to these changes; for example: If the user picks up the mobile phone, takes out the mobile phone from the pocket, or finishes exercising, etc., if the changes of these environmental state information can be monitored, the user's demand for using the mobile phone can be predicted, that is, the need for fingerprint unlocking. Such motion information may be obtained through, for example, a distance sensor, a position sensor, a gravity sensor, and the like, and details on how to obtain such information will not be repeated in this embodiment of the present invention.

Based on the above description, the user's demand for using the mobile phone can be predicted based on the change of the environmental state information; the power management service is a functional module used for power control in the operating system, and lighting the screen may involve loading the driver required for the startup screen. Programs, power control and other aspects; the embodiment of the present invention does not focus on how the power management service starts the screen, so it will not be described in detail here.

The registered fingerprint is the fingerprint data stored locally in the mobile terminal, and is used for comparison with the fingerprint data input by the user to determine whether the fingerprint data input by the user is the same as the registered fingerprint; the registered fingerprint is used for unlocking the black screen in this embodiment. The fingerprint used, the registered fingerprint can also be the registered fingerprint of the application in the mobile terminal;

In the embodiment of the present invention, since the power management service has been pre-started before the fingerprint data is acquired, the startup process of the power management service can be processed in parallel with the fingerprint collection device and the fingerprint comparison process, which can save time in fingerprint comparison. After the comparison is completed and it is determined that the comparison is passed, it is necessary to wait for the time for the power management service to start, so the time for unlocking the black screen can be shortened, thereby improving the efficiency of fingerprint unlocking.

In addition, the embodiment of the present invention also provides a specific implementation scheme for predicting whether there is a fingerprint unlocking requirement based on the environmental status information of the mobile terminal, as follows: the above-mentioned processor 701 is used to monitor the environmental status information of the above-mentioned mobile terminal; through the above-mentioned environmental status information Predicting whether there is a demand for fingerprint unlocking includes: a fingerprint acquisition device used to monitor whether an object is close to the above-mentioned mobile terminal, and if an object is close to the above-mentioned fingerprint acquisition device, it is determined that there is a demand for fingerprint unlocking;

Or, monitor the motion state information of the above-mentioned mobile terminal, if it is determined that the above-mentioned mobile terminal is picked up from a standstill according to the above-mentioned motion state information, it is determined that there is a fingerprint unlocking requirement, or, if it is determined according to the above-mentioned motion state information that the motion speed of the above-mentioned mobile terminal is from If the change from high to low is higher than the predetermined threshold and the movement speed is lower than the threshold, it is determined that there is a need for fingerprint unlocking.

Further, after pre-starting the power management service, energy consumption will increase and the fingerprint unlocking requirement is a prediction result that may not be accurate every time. In order to save possible waste of energy consumption, the embodiment of the present invention provides the following solutions: The above-mentioned processor 701 is further configured to hibernate the above-mentioned power management service if no fingerprint data is received within a predetermined period of time after the above-mentioned pre-starting of the above-mentioned power management service.

The above predetermined time period can be set based on experience. For example, when the user takes out the mobile phone from his pocket and the screen is unlocked within 10S, the predetermined time period can be set to 10S, or a little longer; other applications The scenarios are deduced in the same way; the specific value of the predetermined time period is not uniquely limited in this embodiment of the present invention. By adopting the solution of this embodiment, the technical effect of reducing energy consumption can be achieved.

In addition, the embodiments of the present invention further provide other technical solutions for accelerating the fingerprint unlocking speed, as follows: the above-mentioned processor 701 is further configured to change the response speed of the fingerprint collecting device of the mobile terminal to a The initial state is to improve as a standard; if the fingerprint data is not received within a predetermined period of time, the response speed of the fingerprint collection device of the mobile terminal is restored to the initial state.

Improving the response speed of the fingerprint collection device is based on the response speed of the fingerprint collection device in the initial state as a standard; the specific improvement method may be to increase the clock frequency of the processor and/or increase the fingerprint collection frequency of the fingerprint collection device, etc. Various technical indicators related to the response speed of the fingerprint collection device, etc., can improve the response speed of the fingerprint collection device, thereby improving the speed of fingerprint collection of mobile terminals in a short time, thereby shortening the fingerprint unlocking time.

In addition, it can be understood that increasing the response speed of the fingerprint collection device may be accompanied by high energy consumption in a short period of time. In order to reduce the energy consumption level of the mobile terminal, the response of the fingerprint collection device will be restored within a predetermined period of time. speed, so that the energy consumption of the mobile terminal is reduced.

Based on the above introduction, the motion state information can relatively determine that the user does not need to use the mobile phone, that is, there is no need for fingerprint unlocking, then in this case, some power consumption control can be performed, as follows: the above-mentioned processor 701, also For monitoring the motion state information of the above-mentioned mobile terminal, if the above-mentioned motion state information is that the above-mentioned mobile terminal is in a stationary state, or, the above-mentioned motion state information is higher than a predetermined speed or acceleration, then reduce the response speed of the above-mentioned fingerprint collection device. below the initial state.

It can be understood that, in addition to reducing the response speed of the fingerprint collection device, if the current mobile terminal has other power-consuming items being executed, it can also be considered to reduce the power consumption occupied by the mobile terminal without affecting the necessary standby function of the mobile terminal. .

Embodiments of the present invention further provide an implementation scheme for improving fingerprint unlocking efficiency, which is specifically as follows: the processor 701 is further configured to obtain the current location information of the mobile terminal before using the fingerprint data to compare with the registered fingerprint;

Determine the security level corresponding to the above-mentioned current location information, and then determine the fingerprint unlocking level corresponding to the above-mentioned security level; the higher the above-mentioned security level, the lower the algorithm complexity corresponding to the above-mentioned fingerprint unlocking level;

If it is a place where the user often goes, such as the user's home, then the use environment where the mobile terminal is located is relatively safe. In this case, it can be appropriately reduced. The security level of fingerprint unlocking, namely: lowering the fingerprint unlocking level, lowering the fingerprint unlocking level. Correspondingly, a fingerprint unlocking algorithm with lower complexity can be used, for example, using less fingerprint feature comparison, or in the fingerprint image comparison process If a lower proportion of the same fingerprint features are obtained in the middle, the authentication is determined to be passed.

Since the unlocking method corresponding to the fingerprint unlocking registration is used, in the case of a higher security level, an algorithm with lower complexity is used, so the speed of fingerprint unlocking will be improved. The above fingerprint unlocking method corresponds to an algorithm with a certain complexity, and the algorithm is used to compare the above fingerprint data with the registered fingerprint when the fingerprint is unlocked.

In this embodiment, it is determined whether the mobile terminal is currently in a relatively safe environment through the location information of the mobile terminal; if it is in a relatively safe environment, the security level of fingerprint unlocking can be lowered, and the corresponding selection complexity is relatively low. A small fingerprint unlocking algorithm is used to shorten the time required for fingerprint unlocking; therefore, the fingerprint unlocking efficiency can be improved on the premise of ensuring the security of the mobile terminal.

The above-mentioned processor 701 is further configured to count the historical location information of the above-mentioned mobile terminal before the above-mentioned acquisition of the current location information of the mobile terminal, and record the higher security level corresponding to the location information with higher occurrence frequency in the historical location information;

Alternatively, the location information setting information is received, and the location information setting information includes the location information and the security level corresponding to the location information.

Among the above two methods of determining the security level corresponding to the location information, the former method is automatically completed by using machine learning. After the historical location information is accumulated, the security level corresponding to the location information can be determined more accurately, which is both accurate and convenient. In one way, the user can set which specific locations are considered safe locations, which better reflects the user's subjective cognition and is more applicable to some specific users. The above two implementation methods are both to determine that certain geographical locations are considered to be relatively safe application environments, and accordingly a fingerprint unlocking algorithm with lower complexity can be used; if other methods are used to achieve the technical purpose, it will not affect the The implementation of the embodiments of the present invention, therefore, the above examples should not be construed as unique limitations on the embodiments of the present invention.
