For example, in fingerprint recognition, some people or some groups have few fingerprint features, and it is difficult to identify a clear fingerprint image when using fingerprints. And every time a fingerprint is used, the fingerprint of the user will be left on the fingerprint collection head, and these fingerprints may be used to replicate the fingerprint. At the same time, fingerprint information may be cracked by orange peel attacks and other methods. In facial recognition, there are individuals with similar facial structures, and at the same time, the facial structure of individuals may change due to some events (for example, the user's facial features change due to factors such as surgery, car accidents, etc.), which leads to difficulty in recognition.

Therefore, the inventor proposes an unlocking method, device, electronic device, and storage medium of an electronic device in the embodiments of the present application. The embodiments of the present application will be described in detail below with reference to the accompanying drawings.

This embodiment provides an unlocking method, which can be applied to a foldable electronic device as shown in FIG. 1 or FIG. 3 . Referring to Figure 4, the method may include the following steps:

Step S110: When the folding electronic device is in a screen-locked state, detect the rotation angle and the number of rotations of the first display area and the second display area.

The screen-locked state refers to a state in which the foldable electronic device is not in use and the display area is locked. At this time, the display area may be in a screen-off state or a screen-on state. After receiving the unlocking operation of the user, the foldable electronic device may be turned on. It can be understood that, when the foldable electronic device is in the locked screen state, the angle between the first display area and the second display area may be any value between 0-180°.

Detecting the rotation angle and number of rotations of the first display area and the second display area may be to detect the rotation angle and number of rotations of the first display area, respectively, and to detect the rotation angle and number of rotations of the second display area; The relative rotation angle and the number of rotations between the first display area and the second display area.

The rotation angle of the first display area refers to the angle that the first display area rotates from the initial state to the stop rotation state during the rotation process, and the rotation angle of the second display area refers to the rotation angle of the second display area from the initial state during the rotation process. The angle by which the state turns to the stop-turn state. It can be understood that the first display area and the second display area can be rotated independently, or can be rotated synchronously, that is, rotated by the same angle at the same time.

The number of rotations refers to the number of times each of the first display area and the second display area rotates, wherein the number of rotations can be counted according to a predetermined rule. As an example: a counting method is shown below, for example, the angle between the first display area and the second display area starts to become smaller as the starting point, and the angle between the first display area and the second display area is no longer Reduction is the end point, and the count is 1, wherein the angle between the first display area and the second display area is no longer reduced, and it does not specifically mean that the angle between the first display area and the second display area is 0, Other values are also possible. Another example: starting from the angle between the first display area and the second display area that starts to decrease, the angle between the first display area and the second display area changes from gradually decreasing to increasing gradually, and when the angle between the first display area and the second display area gradually decreases. The end point is when the angle no longer continues to increase, and the count is 1. It can be understood that, in some other implementations, the counting rule can also be set in other forms.

In some implementations, counting starts when the first display area and the second display area start to rotate, and each time the first display area and the second display area complete one rotation, the first display area and the second display area are detected. The display area and the second display area maintain the pause time of the current relative angle. When the pause time is greater than or equal to the preset time length, the counting of the number of rotations is terminated. The preset duration may be 5s, 10s, or the like. This counting method can more accurately determine the number of rotations of the current user, and prevent a thief from quickly folding the foldable electronic device multiple times so that the count exceeds the specified number of times to complete the unlocking.

It can be understood that, in some embodiments, among the first display area and the second display area, only one display area may rotate, so the number of rotations of the first display area and the number of rotations of the second display area may be the same or possible. Are not the same.

Step S120: Unlock the foldable electronic device when the rotation angle conforms to the specified angle, and the rotation conforms to the specified angle.

The specified angle refers to a preset rotation angle, which is used to determine whether the user is performing the unlocking operation during the folding process and whether the unlocking operation is performed correctly. The specified number of times refers to the number of times that the user needs to effectively rotate the first display area and the second display area during the unlocking process. The effective rotation of the first display area and the second display area refers to the rotation of the first display area and the second display area. Specify the angle. Both the specified angle and the specified number of times can be preset in the system or set by the user.

It can be understood that, in some embodiments, as long as the number of rotations is greater than or equal to the specified number of times, the unlocking operation can be completed, while in other embodiments, the unlocking operation can be completed only when the number of rotations is equal to the specified number of times, that is, when the When the number of rotations of the user is greater than the specified number of times, the unlocking cannot be completed, which can further improve the security.

It can be understood that, in some embodiments, the method for obtaining the specified angle and the specified number of times may be input by the user according to their own needs, or by completing the same rotation operation, the specified angle and specified number of times of the response are obtained by obtaining the user's rotation operation. information.

As an example, FIG. 5 shows a method for obtaining a specified angle and a specified number of times. The method may include the following steps:

Step S111: Display an encryption interface.

The encryption interface is used to prompt the user to perform lock screen encryption settings, and the encryption interface can be displayed when the user sets the foldable electronic device for the first time. As an example, FIG. 6 shows an encryption interface, the encryption interface may include a password setting option list, the list may include a password for setting rotation parameters (that is, password setting by rotating parameters), and may also include entering a digital password , input fingerprint password, input facial feature password, etc., which are selected by the user. When the user chooses to set the rotation parameter password, the encryption setting can be performed by rotating the first display area and the second display area. In some embodiments, the encryption interface may also be displayed after responding to the user's password setting request.

Step S112: Detect the rotation angle and the number of rotations of the first display area and the second display area.

After the user chooses to enter the encryption setting mode, the user's rotation operation is detected, and information such as rotation angles and rotation times of the first display area and the second display area are acquired. Wherein, the rotation angle of the first display area and the second display area can be obtained from the time the user enters the encryption setting mode, and the angle between the first display area and the second display area can be obtained as the first relative angle, and then obtained during each rotation process. angle of rotation. Specifically, the first relative angle between the first display area and the second display area at the initial position can be detected, and the second relative angle between the first display area and the second display area after the rotation is completed angle, and the difference between the first relative angle and the second relative angle is determined as the rotation angle.

The number of rotations can be acquired by acquiring the number of rotations in a set time period. It can also be obtained in the following manner, starting counting from the time the first display area and the second display area start to rotate, and detecting the first display area after each rotation of the first display area and the second display area is completed. The first display area and the second display area maintain the pause time of the current relative angle. When the pause time is greater than or equal to the preset time length, the counting of the number of rotations is terminated.

In some embodiments, when acquiring the rotation and the number of rotations between the first display area and the second display area, the current value of the rotation angle and the value of the number of rotations may be displayed on the display area in real time, so that the user can know the current You can adjust the setting process to better suit your own needs.

Step S113: Store the detected rotation angle as the specified angle, and store the detected rotation times as the specified number of times.

The above-mentioned ways of acquiring the rotation angle and the number of rotations can give the user a more intuitive feeling of the rotation operation, so that the user can choose a setting method that is more suitable for him. It is convenient for the unlocking operation to be performed in a more appropriate manner when the unlocking operation is performed subsequently.

In some embodiments, the user's biometric identification information, such as fingerprint information, facial feature information, iris information, retinal information, and vein feature information, etc., can also be collected, and the collection is bound to the number of rotations and the rotation angle set by the user. , then store. In this way, subsequent users can also perform identity verification through fingerprints and facial feature information, etc., and unlocking operations can only be performed after the identity verification is qualified.

With the unlocking method provided in this embodiment, since the user is used to unlock the first display area and the second display area by rotating operations, criminals will not be allowed to steal facial features, passwords, etc. by acquiring fingerprints on electronic devices or by other means way to crack, to achieve a more secure effect.

In some embodiments, the specified angle includes a first specified angle representing a preset rotation angle of the first display area and a second specified angle representing a preset rotation angle of the second display area. Meanwhile, in some embodiments, the specified number of times includes a first specified number of times when the first display area is rotated by a first specified angle and a second number of times when the second display area is rotated by a second specified angle.

Referring to Figure 7, the unlocking method may include the following steps:

Step S210: When the foldable electronic device is in a screen-locked state, respectively detect the rotation angle and the number of rotations of the first display area and the second display area.

Usually, when the user does not use the foldable electronic device, the foldable electronic device is folded up, that is, the angle between the first display area and the second display area is 0° at this time. However, when the user opens the foldable electronic device, it is usually done in a manner of not moving one display area and rotating the other rotating area. Especially for an inward-folding foldable electronic device, when one of the display areas is rotated, the other display area that has not been rotated faces the user.

Step S220: When it is detected that the rotation angle of the second display area remains 0 within a preset time period, the rotation angle of the first display area conforms to the first rotation angle and is consistent with the first rotation angle. When the number of rotations is a specified number of times, at least one of the first display area and the second display area is unlocked.

The preset duration can be a system preset or a user-defined setting, for example, it can be set to 3s, 5s, etc. The rotation angle of the second display area may refer to the rotation angle of the second display area relative to the reference plane, and the reference plane may be a horizontal plane, a vertical plane, or the like. When it is satisfied that the rotation angle of the second display area remains 0, and the number of rotations for which the rotation angle of the first display area conforms to the first rotation angle is detected to be a specified number of times, one of the first display area and the second display area or Two to unlock.

Wherein, when selecting the unlocked display area, the selection can be made according to the user's preference or the user's current holding posture, the first display area and the second display area can be unlocked at the same time, or only the first display area and the second display area can be unlocked. One of the two display areas.

In some embodiments, when it is detected that the rotation angle of the second display area remains 0 within a preset period of time, the rotation angle of the first display area conforms to a first specified angle and conforms to the first rotation angle When the number of rotations is a specified number of times, the second display area is unlocked. The advantage of this implementation is that when the user always keeps the rotation angle of the second display area at 0, it means that the second display area may always face the user or be more convenient for the user to view (for example, always keep the horizontal state), at this time Unlocking the second display area allows the user to use the second display area quickly, and since the first display area is not unlocked, power consumption of the first display area can be saved, thereby achieving the purpose of power saving. In addition, this unlocking method can also achieve a more secure effect. Users can place personal privacy content in the first display area. When using electronic devices outside, they can only unlock the second display area for use to avoid personal privacy leakage. .

The unlocking method provided in this embodiment can achieve better privacy protection effect, and is not easy to be cracked by criminals, and saves more power in some usage environments.

In some embodiments, referring to FIG. 8 , the unlocking method may include the following steps:

Step S310: When the foldable electronic device is in a screen-locked state, respectively detect the rotation angle and the number of rotations of the first display area and the second display area.

Step S320: When it is detected that the included angle between the first display area and the second display area conforms to the specified angle within the preset duration, and the number of rotations that conform to the specified angle is the specified number of times, the first The display area and the second display area are unlocked simultaneously.

In some embodiments, the rotation angle and the number of rotations between the first display area and the second display area may be directly detected, and then the rotation angle and number of rotations of the first display area and the rotation angle of the second display area and number of turns. The rotation angle of the first display area and the second display area refers to the difference between the angle between the initial positions of the first display area and the second display area and the angle between the real-time positions. For example, the first display area and the second display area are in a relatively expanded state at the initial position, that is, the angle between the first display area and the second display area is approximately 180°. Rotate until the included angle between them is approximately 90°, and the rotation angle between the first display area and the second display area is 90°-180°=-(90°). Among them, "-(negative)" means that the angle between the first display area and the second display area becomes smaller when the rotation angle is "+(positive)". The angle between the display area and the second display area becomes larger. At this time, the sum of the rotation angle of the first display area and the rotation angle of the second display area is -90°. It can be understood that the included angle between the first display area and the second display area in the initial state may be any angle.

For example, in some implementations, the first display area and the second display area are rotated synchronously (ie, rotated at the same time). The first display area and the second display area can be unlocked when the change amount of the relative angle is a specified angle and the number of rotations is a specified number of times.

This embodiment simplifies the measurement of the rotation angle of the first display area and the second display area, and only needs to obtain the relative angle between the first display area and the second display area and the number of rotations as the judgment criteria, which greatly simplifies Detection process, saving system resources. In addition, the relative rotation angle of the first display area and the second display area is more convenient to measure, and the hardware cost for detection is also saved.

In some embodiments, the foldable electronic device is further provided with a fingerprint recognition module for collecting or verifying the user's fingerprint feature information, and the fingerprint recognition module can be arranged in the first display area, the second display area or the foldable electronic device of other parts. Referring to Figure 9, the unlocking method may include the following steps:

Step S410: Detect the recognition result of the fingerprint recognition module, the rotation angle and the rotation times of the first display area and the second display area when the folding electronic device is in the locked screen state.

It can be understood that the detection of the identification result of the fingerprint identification module may be performed simultaneously with the detection of the rotation angle and the number of rotations of the first display area and the second display area, or may be performed in steps. When the two are carried out step by step, the recognition result of the fingerprint recognition module can be detected first, and the rotation angle and the number of rotations of the first display area and the second display area can also be detected first, which does not need to be limited here. By identifying the unlocked user's fingerprint features, the user's information can be further determined to prevent being cracked by criminals.

In some embodiments, step S410 may be performed in the following manner: when the folding electronic device is in a locked screen state, detecting the first display area and the second display area when the fingerprint recognition module is continuously pressed The angle of rotation and the number of rotations.

The fingerprint identification module is continuously pressed, which means that the fingerprint identification module can collect fingerprint information during the entire rotation process. The system can collect and store the fingerprint information of legal users in advance as legal fingerprint information. It can be understood that the legal fingerprint information may include fingerprint information of one or more legal users. It can be understood that "continuous pressing" does not specifically refer to exerting pressure on the fingerprint identification module. In some embodiments, fingerprint information can also be collected by contacting the fingerprint identification module, which is also feasible.

Since the fingerprint information of the user who performs the unlocking operation needs to be continuously collected during the detection process, the fingerprint identification module can be set in the first display area or the second display area, so that the user can perform the rotation operation more conveniently. touch fingerprint recognition module. Since the fingerprint information needs to be collected during the entire rotation process, the user who performs the unlocking operation needs to be very familiar with the unlocking rules, and at the same time can accurately find the position of the fingerprint recognition module. The probability of unlocking through experiments and other methods will be greatly reduced.

Step S420: Unlock the foldable electronic device when the rotation angle conforms to the specified angle, and the number of rotations that conform to the specified angle is the specified number of times, and the identification result of the fingerprint identification module is the specified user.

The unlocking operation is performed only when the fingerprint information recognized by the fingerprint recognition module is always the designated user. In this way, the security of unlocking the electronic device can be greatly improved.

In some embodiments, a plurality of fingerprint identification modules may be provided, and the plurality of fingerprint identification modules may be respectively disposed on different display areas. For example, a fingerprint identification module is set in each display area. At this time, when the user performs a rotation operation, multiple fingerprint identification modules can simultaneously collect multiple fingerprint feature information of the user, so as to further improve the security of unlocking.

For example, when the folding electronic device is in a locked screen state, detect the rotation angle and rotation times of the first display area and the second display area when each of the fingerprint recognition modules is continuously pressed at the same time. When the rotation angle conforms to the specified angle, and the number of rotations conforming to the specified angle is the specified number of times, and the identification result of each fingerprint identification module is the specified user, the foldable electronic device is unlocked. This embodiment can not only improve the security of unlocking, but also will not increase the difficulty of the user's operation, because the user needs to control a display area with the left and right hands respectively when the user rotates, and the user can place the thumbs of the left and right hands respectively. In the fingerprint collection area of the first display area and the second display area, press the fingerprint recognition module continuously. For criminals, even if they watch the user's unlocking process, it is difficult to complete the unlocking operation because they are not familiar with the unlocking rules.

In some embodiments, the foldable electronic device is provided with an image capture module, such as a 3D structured light module, which can be used to capture, analyze and identify the user's facial features. Referring to Figure 10, the unlocking method may include the following steps:

Step S510 : when the foldable electronic device is in the locked screen state, turn on the image capture module, and detect the rotation angle and the rotation times of the first display area and the second display area.

During the rotation operation, the image acquisition module collects and identifies the user's feature information, such as the user's facial feature information, and compares it with the pre-stored user's facial feature information. It can be understood that, in step S510, in the whole process of the rotation operation, the image acquisition module needs to be turned on, and the characteristic information of the user is continuously collected.

Step S520: When the rotation angle conforms to the specified angle, and the number of rotations conforming to the specified angle is the specified number of times, and the image capture module identifies the specified user, unlock the foldable electronic device.

In this embodiment, during the user's rotation operation, the user's characteristic information can be identified to determine whether it is a rotation operation performed by a designated user, which can further enhance the security of the unlocking operation. At the same time, the user only needs to collect the user's facial feature information in real time when the user performs the rotation operation, and the user's operation and unlocking time will not be additionally increased.

In some embodiments, referring to FIG. 11 , the unlocking method may include the following steps:

S610: When the foldable electronic device is in a locked screen state, respectively detect the rotation angle and the number of rotations of the first display area and the second display area.

S620: When the number of rotations of the rotation angle conforming to the first specified angle is the first specified number of times, and when the number of rotations of the second rotation angle conforming to the second specified angle is the second specified number of times, apply the foldable electronic Device unlocked.

The definitions of the first specified angle, the second specified angle, the first specified number of times, and the second specified number of times may refer to the foregoing content.

By separating the first display area and the second display area for detection, the first specified angle and the second specified angle can be set to be the same or different, and the first specified number of times and the second specified number of times can be set to be the same or different. Significantly increases the variety of unlocking conditions and the combination of unlocking conditions, and significantly improves the security of unlocking operations.

As an example, the first specified angle is set to 45°, the first specified number of times is set to 2, the second specified angle is set to 30°, and the second specified number of times is set to 3 times. At this time, when the user performs the unlocking operation, the first display area needs to be rotated twice and the rotation angle of each rotation should reach 45°. The second display area needs to be rotated 3 times, and the rotation angle of each rotation should reach 30° to complete the unlocking.

In the above-mentioned embodiments, even if the unlocking process is observed by criminals when the user performs the unlocking operation in a public place, it is difficult to copy or reproduce, which increases the difficulty of unlocking.

In some embodiments, the first specified number of times of the first specified angle and the second specified number of times of the second specified angle may also be performed in a predetermined order. That is, when the first display area completes the rotation of the first specified number of times and the second display area completes the rotation of the second specified number of times, the rotation is not performed simultaneously, but is performed staggered in a predetermined order.

As an example, the number of times of the first rotation of the first specified angle is set to be 3 times, and the number of times of the second rotation of the second specified angle is set to be 2 times. The predetermined sequence can be performed by alternately performing the rotation of the first display area and the rotation of the second display area. For example, the rotation of the first display area is performed first, then the rotation of the second display area is performed, and then the rotation of the first display area is performed. ,And so on. This implementation can further increase the combination of unlocking conditions and increase the difficulty of cracking by criminals.

In some embodiments, in step S620, the first specified angle may include two or more different angle values, and the two or more different angle values may be arranged in a first predetermined order and correspond to The specified angle for each rotation of the first display area. The second designated angle may include two or more different angle values, and the two or more different angle values may be arranged in a second predetermined order and correspond to the designation of each rotation of the second display area respectively angle. It can be understood that the first predetermined order and the second predetermined order may be the same order, or may be different orders. The above-mentioned embodiments can generate more permutations and combinations, further improving the security of unlocking.

As an example: the first specified number of times is set to 3 times, and the specified angles corresponding to each time are 45°, 60°, and 45° respectively, the second specified number of times is set to 2 times, and the specified angle corresponding to each time is 30° , 60°. At this time, when the user performs the unlocking operation, the first display area needs to be rotated three times. The rotation angle of the first rotation is 45°, the rotation angle of the second rotation is 60 degrees, and the rotation angle of the third rotation is 45°. . The second display area needs to be rotated twice, and the rotation angle of the first rotation is 30°, and the rotation angle of the second rotation is 60°. Only then can the unlocking be completed.

In some embodiments, the first predetermined order and the second predetermined order may be uniformly arranged according to predetermined rules, that is, form a continuous order. As an example: the first specified number of times is set to 3 times, and the specified angles corresponding to each time are 25°, 50°, and 35° respectively, the second specified number of times is set to 2 times, and the specified angle corresponding to each time is 30° , 45°. The rotation modes can be arranged as follows: the first rotation, the first display area rotates 25; the second rotation, the first display area rotates 50°; the third rotation, the second display area rotates 30°; the fourth rotation Rotation, the first display area rotates 35°; the fifth rotation, the second display area rotates 45°. As a result, the number of permutations and combinations can be further increased, and the unlocking security can be improved.
