Description
Technical Field
The invention relates to the technical field of mobile terminal control, in particular to an unlocking method of a mobile terminal screen and a mobile terminal.
Background
Nowadays, a mobile phone becomes an increasingly important electronic consumer product for a user, and a plurality of extended functions are also applied to the mobile phone, especially the confidentiality of the mobile phone is increasingly important as the property (such as a payment treasure and a WeChat) and the privacy (such as an album, a WeChat and a QQ) of the user are related, so that an unlocking mode (such as rapid fingerprint unlocking) of the mobile phone is also increasingly a selling point of mobile phone manufacturers. The unlocking mode of the current market mobile phone is roughly divided into:
1. unlocking by using a mobile phone interface password, wherein the unlocking comprises mobile phone input number unlocking and nine-grid pattern drawing unlocking;
2. the fingerprint identification sensor is used for fingerprint unlocking, wherein the fingerprint identification sensor is placed in front of the mobile phone to realize front fingerprint unlocking, and the fingerprint sensor is placed behind the mobile phone to realize rear fingerprint unlocking.
The unlocking mode of unlocking by using the screen password or unlocking by drawing a pattern on the screen of the mobile phone is easy to see by others in the unlocking process, or the scratch is easy to form on the pattern scratched on the mobile phone due to the fact that the finger of the pattern has sweat, so that the pattern is cracked by others. In addition, when the user uses the mode to unlock, the operation process of the user unlocking is relatively complex, and especially when the user operates with one hand, the operation is inconvenient, and the user experience is poor.
In addition, although unlocking by using fingerprint identification is more and more a trend of mobile phone manufacturers, the method has the advantages of simple operation and high unlocking speed, the condition that the unlocking cannot be performed or the unlocking cannot be performed by a specific fingerprint can be performed due to the fact that the fingerprint identification is a hardware sensor and the failure condition of single body failure is certain, and the fingerprint unlocking cannot be performed usually when the finger is dirty or water stain during unlocking. Therefore, fingerprint identification unlocking presents uncertainty to the user's privacy. In addition, in the design and manufacturing process of the mobile phone, the hardware cost and the design difficulty are greatly increased due to the increase of the fingerprint identification module, and the reliability of the whole mobile phone is reduced.
Therefore, the existing mobile phone unlocking mode cannot reduce the design cost and enhance the confidentiality while ensuring the operation convenience of a user.

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the disclosure to those skilled in the art.
First embodiment
As shown in fig. 1, a flowchart of an unlocking method for a mobile terminal screen according to a first embodiment of the present invention is shown, and the method includes:
step 101: and acquiring an instruction for unlocking the screen of the mobile terminal in the screen locking state of the screen of the mobile terminal.
The embodiment of the invention is applied to mobile terminals such as mobile phones and tablet computers provided with two cameras, and an unlocking image library is pre-established in the mobile terminal. The unlocking image can be set by entering a setting page of the mobile terminal. After the mobile terminal enters the setting page of the mobile terminal, the first camera or the second camera of the mobile terminal is used for shooting the image of the target object, and the image is stored in the unlocking image library so as to be used when the screen is unlocked by the first camera and the second camera.
The user can take images of various articles or images of different parts of the body of the user (such as the face and the palm print) or images of specific gestures set by the user as the unlocking images. Therefore, the unlocking objects of the embodiment of the invention are flexible and various.
In addition, when the mobile terminal is in a screen locking state, a user can perform corresponding operation on the mobile terminal according to a camera quick starting mode supported by the mobile terminal, so that the mobile terminal generates an instruction for unlocking a screen of the mobile terminal, and then the first camera and the second camera are started according to the instruction.
Step 102: and starting the first camera and the second camera according to the instruction.
After the instruction for unlocking the screen of the mobile terminal is obtained in step 101, the first camera and the second camera can be started according to the instruction, and a photographing mode of the first camera and a photographing mode of the second camera are entered, so that a first preview window of the first camera and a second preview window of the second camera can be displayed on a display interface of the mobile terminal together, and the first preview window and the second preview window are not affected by each other.
Step 103: and acquiring a first image acquired by the first camera and a second image acquired by the second camera.
After the first camera and the second camera are started, a first image collected by the first camera and a second image collected by the second camera can be acquired. The embodiment of the invention utilizes the first image and the second image to unlock the screen, so that the unlocking process is difficult to crack, and the security effect on the mobile terminal is better.
Step 104: and executing screen unlocking operation according to the first image, the second image and an unlocking image stored in an unlocking image library in advance.
After the first image captured by the first camera and the second image captured by the second camera are acquired through step 103, the screen unlocking operation may be further performed according to an unlocking image stored in the unlocking image library in advance. And when the unlocking is successful, the mobile terminal enters a normal operation interface. If the unlocking is not successful within the preset time period, the mobile terminal enters a screen-off standby state to save electric quantity.
In addition, the mode of utilizing the double cameras to capture images for unlocking the screen can be further expanded to the starting aspect of an application program (APP) of the mobile terminal. That is, when using the APP of mobile terminal, for example, pay treasure, WeChat, QQ, album etc. because these APPs relate to mobile terminal user's secrecy and property safety, so can use the high two camera unblock modes of security level to unblock, prevent that other users from unblocking at will, have dual protection to user's privacy and property.
Therefore, according to the embodiment of the invention, the instruction for unlocking the screen of the mobile terminal can be obtained when the mobile terminal is in the screen locking state, so that the first camera and the second camera of the mobile terminal are started according to the instruction, the target images are respectively captured by the first camera and the second camera, and the screen unlocking operation is completed according to the unlocking images stored in the unlocking image library in advance. Therefore, according to the embodiment of the invention, no hardware equipment is added, screen unlocking can be realized only by using the double cameras of the mobile terminal, the operation is simple and convenient, the cracking difficulty is high, the unlocking images in the unlocking image library are only known by the user, the confidentiality is good, and the technical problems that the design cost cannot be reduced and the confidentiality cannot be enhanced while the operation convenience of the user cannot be ensured in the conventional unlocking mode are effectively solved.
Second embodiment
As shown in fig. 2, a flowchart of a screen unlocking method of a mobile terminal according to a second embodiment of the present invention is shown, and the method includes:
step 201: and acquiring an instruction for unlocking the screen of the mobile terminal in the screen locking state of the screen of the mobile terminal.
The embodiment of the invention is applied to mobile terminals such as mobile phones and tablet computers provided with two cameras, and an unlocking image library is pre-established in the mobile terminal. The unlocking image can be set by entering a setting page of the mobile terminal. After the mobile terminal enters the setting page of the mobile terminal, the first camera or the second camera of the mobile terminal is used for shooting the image of the target object, and the image is stored in the unlocking image library so as to be used when the screen is unlocked by the first camera and the second camera.
The user can take images of various articles or images of different parts of the body of the user (such as the face and the palm print) or images of specific gestures set by the user as the unlocking images. Therefore, the unlocking objects of the embodiment of the invention are flexible and various.
In addition, when the mobile terminal is in a screen locking state, a user can quickly start the first camera and the second camera according to a camera quick starting mode supported by the mobile terminal. Specifically, for example, when the mobile terminal is in a screen lock state, the camera of the mobile terminal may be quickly started by pressing a screen-up key of the mobile terminal or returning to the key for a preset number of times, or the camera of the mobile terminal may be quickly started by using a touch operation in a preset area of a screen-up interface of the mobile terminal. For example, the camera is directly started by quickly double-clicking the power-on screen-up key, wherein the time interval between two successive times of pressing the power-on screen-up key can be automatically adjusted by a user; or, double click returns the button fast, wherein, some mobile terminal's model returns the button and is the entity button, then the user double click just can start the camera very simply fast, but some models are electric capacity touch button, can start the camera fast through quick touch equally, but when mobile terminal placed in the pocket, need close electric capacity touch and return the function that the button started the camera fast to avoid causing the maloperation.
Step 202: and starting the first camera and the second camera according to the instruction.
After the instruction for unlocking the screen of the mobile terminal is obtained in step 201, the first camera and the second camera can be started according to the instruction, and a photographing mode of the first camera and a photographing mode of the second camera are entered, so that a first preview window of the first camera and a second preview window of the second camera can be displayed on a display interface of the mobile terminal together, and the first preview window and the second preview window are not affected by each other.
Step 203: and acquiring a first image acquired by the first camera and a second image acquired by the second camera.
After the first camera and the second camera are started, a first image collected by the first camera and a second image collected by the second camera can be acquired. The embodiment of the invention utilizes the first image and the second image to unlock the screen, so that the unlocking process is difficult to crack, and the security effect on the mobile terminal is better.
Step 204: and executing screen unlocking operation when the first image and the second image are acquired by the first camera and the second camera simultaneously and are matched with the unlocking image in the unlocking image library.
Preferably, step 204 comprises: respectively comparing the first image and the second image with the unlocking images in the unlocking image library; when a first target unlocking image matched with the first image and a second target unlocking image matched with the second image exist in the unlocking image library, judging whether the first image and the second image can form a preset image combination; if the first image and the second image can form the image combination, acquiring a first time stamp of the first image and a second time stamp of the second image; judging whether the first time stamp is consistent with the second time stamp; and if the first time stamp is consistent with the second time stamp, executing screen unlocking operation.
Namely, the images acquired by the first camera and the second camera of the mobile terminal at the same time must be two images in a preset image combination, so that the unlocking can be successfully performed. For example, A, B, C unlocking images are stored in the unlocking image library, a first target unlocking image matched with the first image and a second target image matched with the second image can form a preset a + B image combination, and the first image and the second image are acquired simultaneously, so that the unlocking can be successfully performed. And when the first target unlocking image and the second target unlocking image are combined by the A + C or C + B image, the unlocking cannot be successfully performed. In addition, if the first target unlocking image and the second target unlocking image are a preset A + B image combination, the first image and the second image are not acquired simultaneously, and the unlocking cannot be successfully performed. Therefore, the unlocking mode has high cracking difficulty and excellent confidentiality.
In addition, from the specific unlocking manner in step 204, the following three unlocking manners may also be extended:
the first method is as follows: when a first target unlocking image matched with the first image and a second unlocking image matched with the second image exist in the unlocking image library, judging whether the first image and the second image can form a preset image combination; and if the first image and the second image can form the image combination, executing screen unlocking operation.
Namely, as long as the first image collected by the first camera and the second image collected by the second camera of the mobile terminal can form a preset image combination, the unlocking can be successfully carried out, wherein the first image and the second image are not required to be collected simultaneously. For example, A, B, C unlocking images are stored in the unlocking image library, and a first target unlocking image matched with the first image and a second target unlocking image matched with the second image can form a preset a + B image combination, so that successful unlocking can be realized. And when the first target unlocking image and the second target unlocking image are combined by the A + C or C + B image, the unlocking cannot be successfully performed. It can be seen that the security performance of this unlocking method is higher, but lower than that of the specific unlocking method of step 204.
The second method comprises the following steps: and executing screen unlocking operation when a first target unlocking image matched with the first image and a second unlocking image matched with the second image exist in the unlocking image library.
That is, as long as the first target unlocking image matched with the first image can be found in the unlocking image library, and the second target unlocking image matched with the second image can be found, the unlocking can be successfully performed. For example, A, B, C unlocking images are stored in the unlocking image library, the first target unlocking image matching the first unlocking image and the second target unlocking image matching the second unlocking image can form any image combination of a + B, A + C, B + C, and the unlocking can be successfully performed. It can be seen that the unlocking method is simple to operate, but the security performance is lower than that of the specific unlocking method of the first method and the step 204.
The third method comprises the following steps: and executing screen unlocking operation when a first target unlocking image matched with the first image or a second target unlocking image matched with the second image exists in the unlocking image library.
Namely, a first image collected by a first camera of the mobile terminal and a second image collected by a second camera of the mobile terminal can be successfully unlocked as long as one of the first image and the second image can find a matched unlocking image in the unlocking image library. For example, A, B, C three unlocking images are stored in the unlocking image library, and as long as any one of the first target unlocking image matching the first image and the second target unlocking image matching the second image is a, B or C, the unlocking can be successfully performed. Therefore, the unlocking mode has very flexible operation, but the security performance is the lowest among the four unlocking modes.
From the unlocking mode of step 204 and the three extended unlocking modes, the user can freely select the unlocking mode according to the flexibility requirement and the confidentiality requirement of the user on the operation method so as to meet different use requirements of the user.
Specifically, for example, when the unlocking image library includes a face image and a gesture image and the user performs screen unlocking in the first mode, after a first image is acquired by a first camera and a second image is acquired by a second camera, feature recognition is performed on the first image to acquire face information, the face information is compared with the face image, if the face information is matched with the face image, the feature recognition is performed on the second image to acquire gesture information, the gesture information is compared with the gesture image, and when the gesture information is matched with the gesture image, screen unlocking operation is performed. The user acquires a face image by using the front camera, acquires a gesture image by using the rear camera, and can successfully unlock the lock when the acquired face image and the gesture image are matched with the face image and the gesture image which are stored in the unlocking image library in advance.
In addition, the step of comparing the first image and the second image with the unlocking image in the unlocking image library respectively includes: calculating a first similarity between the first image and the unlocking image in the unlocking image library; when the first similarity is larger than a first preset threshold value, determining an unlocking image corresponding to the first similarity as the first target unlocking image; calculating a second similarity of the second image and the unlocking image in the unlocking image library; and when the second similarity is larger than a second preset threshold value, determining the unlocking image corresponding to the second similarity as the second target unlocking image.
That is, the embodiment of the present invention adopts an image processing technique, and compares the first image and the second image acquired in step 203 with the pre-stored unlock image to obtain a first similarity after the first image comparison and a second similarity after the second image comparison. When the first similarity is larger than a first preset threshold value, finding a first target unlocking image matched with the first image; and when the second similarity is larger than a second preset threshold value, finding a second target unlocking image matched with the second image. The first preset threshold and the second preset threshold are both related to the balance starting speed of the mobile terminal and the accuracy of the identification card.
In addition, when a user records an initial picture, the angle of the camera capturing the target image may change along with the change of the use habit, so that the real-time updating of the unlocking image is very important for unlocking. Therefore, further, after the step 204, it is further determined whether the first similarity and the second similarity are within a preset range; when the first similarity is within the preset range, updating the first image corresponding to the first similarity to the unlocking image library; and when the second similarity is within the preset range, updating the second image corresponding to the second similarity to the unlocked image library.
Further, in order to make the accuracy of the updated unlock image better, and thus to more quickly unlock the screen by using the camera, after the step of determining whether the first similarity and the second similarity are within the preset range, the method further includes: when the number of times that the first similarity is within the preset range is greater than a third preset threshold, updating the first image corresponding to the first similarity within the preset range to the unlocking image library; and when the number of times that the second similarity is within the preset range is greater than a fourth preset threshold, updating the second image corresponding to the second similarity within the preset range to the unlocking image library.
For example, suppose that three unlocking images X1, X2, and X3 are stored in the unlocking image library, and the user uses X1 and X2 to unlock n times, and the similarity obtained by calculation when unlocking with X1 and X2 each time is Ni and Mi respectively (where i takes values of 1 to n, and n is a positive integer).
If k (k is smaller than N) similarities in the N similarities from N1 to Nn are within a preset range, and if k reaches a third preset threshold, adding a first image corresponding to the first similarity within the preset range to the unlocked image library; in addition, if h (h is smaller than n) similarity degrees in the n similarity degrees from M1 to Nn are within the preset range, if h reaches a fourth preset threshold, adding a second image corresponding to the second similarity degree within the preset range to the unlocking image library.
After the unlocking image library is updated in the above mode, when the screen is unlocked by subsequently utilizing the first camera and the second camera, the unlocking speed can be increased, and the use experience of a user is further improved.
In addition, the unlocking images in the unlocking image library can be synchronously stored to the network side, so that a user can download the unlocking images to the changed mobile terminal again from the network side after the mobile terminal is changed, and the trouble of shooting the unlocking images by using the camera again is avoided. For example, a mobile terminal user can apply for an account online, and automatically store and update an unlocking image of the account in an unlocking image library, so that the user can log in the account through networking after losing the mobile terminal, and download the unlocking image to the local computer, and along with the use of the mobile terminal, the user can automatically update and adjust the unlocking image in the unlocking image library, and the use experience of the user is further improved.
Therefore, the unlocking method of the mobile terminal screen provided by the embodiment of the invention only needs to enter the camera shooting mode by one key, the operation is simple, and the unlocking object is free. The unlocking object of the fingerprint unlocking in the prior art is single, the fingerprint unlocking can be performed only by specific finger lines, and if the weather is cold in winter, fingers are cracked, or the fingers are dirty or have water stain, the fingerprint unlocking is almost invalid.
In addition, the mobile terminal applied to the embodiment of the invention does not add any hardware, and the cost and the use reliability of the whole mobile terminal have certain advantages compared with a fingerprint unlocking mode. In addition, when a user carries an object by hand or holds a child, the mobile terminal can possibly slide down by using fingerprint identification of the mobile terminal under the condition of only one-hand operation, but the mobile terminal can be conveniently operated by one hand by capturing images by the aid of the camera to unlock, and the mobile terminal can be unlocked simply and quickly even if the hand is dirty and has water stains or carries the object.
In summary, the embodiment of the invention can unlock the mobile terminal by capturing the target image through the existing first camera and the second camera of the mobile terminal on the premise of not adding any hardware equipment, and the unlocking method is flexible and various, the operation is simple and rapid, and the unlocking can be completed by one hand. In addition, the unlocking image in the unlocking image library is only known by the user, the confidentiality is good, the unlocking image in the unlocking image library can be updated in real time, the subsequent unlocking speed can be further accelerated, and the use experience of the user is improved. Therefore, the technical problems that the existing unlocking mode cannot ensure the operation convenience of users, reduce the design cost and enhance the confidentiality are effectively solved.
