Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, fig. 1 is a flowchart of a face recognition method provided in an embodiment of the present invention, and is applied to a mobile terminal. As shown in fig. 1, the method comprises the following steps:
In step 101, when an owner of a mobile terminal borrows the mobile terminal in an unlocked state for use by others, if the others want to obtain a face recognition unlocking authority, the mobile terminal can acquire face feature information of a user to be added through a front-facing camera, that is, the mobile terminal can acquire first face information through the front-facing camera; and second face information is acquired through the rear camera. The first face information is face feature information of a user who wants to obtain face recognition unlocking authority.
And 102, judging whether the second face information is matched with the characteristic information in the face database.
In step 102, the mobile terminal may determine whether the second face information matches the feature information in the face database. The feature information in the face database is face feature information of a master user, the master user is the first user who obtains face recognition unlocking authority, and the master user is the owner of the mobile terminal under normal conditions.
And 103, if the second face information is matched with the feature information in the face database, adding the first face information serving as the feature information into the face database.
In step 103, if the second face information matches with the feature information in the face database, that is, if the second face information matches with the facial feature information of the master user, that is, if the second face information matches with the facial feature information of the master of the mobile terminal, the first face information may be added to the face database as the feature information. That is, the first face information may be set as the feature information having the unlocking authority. That is, if the mobile terminal is in the screen locking state at this time, the user to be added, whose facial feature information is set as the feature information having the unlocking authority, can immediately perform face recognition and unlock the screen.
It should be noted that the user to be added, whose facial feature information is set as feature information having an unlocking right, may be referred to as a guest user. The visitor user is a user except the master user and has the face recognition unlocking authority, namely the visitor user is a user except the master of the mobile terminal and has the face recognition unlocking authority. There may be multiple guest users.
If the second face information is not matched with the feature information in the face database, that is, if the second face information is not matched with the face feature information of the master user, that is, if the second face information is not matched with the face feature information of the master of the mobile terminal, it can be determined that the first face information is the feature information without the unlocking authority, and at this moment, the mobile terminal can store the face feature information of the user to be added, that is, the mobile terminal can store the first face information.
It should be noted that although the mobile terminal stores the facial feature information of the user to be added, that is, although the mobile terminal stores the first face information, since the facial feature information of the user to be added is determined to be the feature information without the unlocking authority, that is, since the first face information is determined to be the feature information without the unlocking authority, if the mobile terminal is in the screen locking state at this time, the user to be added whose facial feature information is determined to be the feature information without the unlocking authority cannot immediately unlock the screen through the face recognition.
In an embodiment of the present invention, the Mobile terminal may be a Mobile phone, a Tablet personal Computer (Tablet personal Computer), a Laptop Computer (Laptop Computer), a Personal Digital Assistant (PDA), a Mobile Internet Device (MID), a Wearable Device (Wearable Device), or the like.
The face recognition method provided by the embodiment of the invention is applied to the mobile terminal, and when the collected second face information is matched with the feature information in the face database, the first face information is added to the face database as the feature information, so that the risk of privacy disclosure can be effectively reduced, the face recognition function is more complete, and the safety of the mobile terminal is improved.
Referring to fig. 2, fig. 2 is a flowchart of another face recognition method provided in the embodiment of the present invention, and is applied to a mobile terminal. The main difference between the present embodiment and the previous embodiment is that after the first face information is added as feature information to the face database, when the authority release operation is detected, the first face information may also be deleted from the face database. At this time, the first face information becomes the feature information having no unlocking authority. As shown in fig. 2, the method comprises the following steps:
In step 201, the mobile terminal has a front camera and a rear camera. When the owner of the mobile terminal borrows the mobile terminal in an unlocking state for other people to use, if the other people want to obtain the face recognition unlocking authority, the mobile terminal can acquire the face characteristic information of a user to be added through the front-facing camera, namely the mobile terminal can acquire first face information through the front-facing camera; meanwhile, second face information can be acquired through the rear camera. The first face information is face feature information of a user who wants to obtain face recognition unlocking authority.
In step 202, the mobile terminal may determine whether the second face information matches the feature information in the face database. The feature information in the face database is face feature information of a master user, the master user is the first user who obtains face recognition unlocking authority, and the master user is the owner of the mobile terminal under normal conditions.
And 203, if the second face information is matched with the feature information in the face database, adding the first face information serving as the feature information into the face database.
In step 203, if the second face information matches with the feature information in the face database, that is, if the second face information matches with the facial feature information of the master user, that is, if the second face information matches with the facial feature information of the master of the mobile terminal, the first face information may be added to the face database as the feature information. That is, the first face information may be set as the feature information having the unlocking authority. That is, if the mobile terminal is in the screen locking state at this time, the user to be added, whose facial feature information is set as the feature information having the unlocking authority, can immediately perform face recognition and unlock the screen.
It should be noted that the user to be added, whose facial feature information is set as feature information having an unlocking right, may be referred to as a guest user. The visitor user is a user except the master user and has the face recognition unlocking authority, namely the visitor user is a user except the master of the mobile terminal and has the face recognition unlocking authority. There may be multiple guest users.
And 204, deleting the first face information from the face database when the permission removing operation is detected.
In step 204, the guest user may be managed. For example, the master user may release the face recognition unlocking authority of a certain guest user according to own will.
It should be noted that, when the visitor user wants to be managed, the face feature information is collected by the front camera of the mobile terminal, and the mobile terminal determines whether the collected face feature information matches with the face feature information of the master user. When the mobile terminal judges that the acquired facial feature information is matched with the facial feature information of the master user, namely the master user is determined to be present, the visitor user is allowed to be managed. Therefore, the visitor user can be effectively prevented from privately managing other visitor users under the condition that the master user does not pay attention.
For example, when a master user wants to release the face recognition unlocking right of a certain visitor user, the master user may acquire face feature information of the master user by using a front-facing camera of the mobile terminal. And then the mobile terminal can compare the collected facial feature information with the facial feature information of the master user, which is stored in advance.
At the moment, the mobile terminal can judge that the collected facial feature information is matched with the facial feature information of the pre-stored main user, namely the main user can be determined to be present, and then the mobile terminal can detect the permission releasing operation.
When the mobile terminal detects the permission release operation, the first face information can be deleted from the face database. That is, when the mobile terminal detects the permission removing operation, the unlocking permission of the first face information can be removed, that is, when the mobile terminal detects the permission removing operation, the face recognition unlocking permission of a certain visitor user can be removed. Thus, the visitor user who is relieved of the face recognition unlocking authority cannot unlock the screen of the mobile terminal through the face recognition.
The face recognition method of the embodiment of the invention is applied to the mobile terminal. And only when the collected second face information is matched with the characteristic information in the face database, the first face information is added into the face database as the characteristic information. Further, after the first face information is added to the face database as the feature information, when the permission release operation is detected, the first face information may be deleted from the face database. At this time, the first face information becomes the feature information having no unlocking authority. The risk of privacy disclosure can be effectively reduced, and the face recognition function is more perfect.
Referring to fig. 3, fig. 3 is a flowchart of another face recognition method provided in the embodiment of the present invention, and is applied to a mobile terminal. The main difference between this embodiment and the previous embodiment is that after determining that the first facial information is the feature information without the unlocking authority, the master user may further determine whether to reset the first facial information to the feature information with the unlocking authority according to the will of the master user. As shown in fig. 3, the method comprises the following steps:
In step 301, when the owner of the mobile terminal borrows the mobile terminal in the unlocked state for use by another person, if the other person wants to obtain the face recognition unlocking authority, the mobile terminal may collect the facial feature information of the user to be added through the front-facing camera first, that is, the mobile terminal may collect the first facial information through the front-facing camera first. If the main user is not present, namely if the owner of the mobile terminal is not present, the mobile terminal cannot acquire the facial feature information of the main user. At this time, the mobile terminal may save the facial feature information of the user to be added, that is, the mobile terminal may save the first facial information.
Although the mobile terminal stores the facial feature information of the user to be added, that is, although the mobile terminal stores the first face information, the stored first face information is determined as feature information that does not have the unlocking authority. Therefore, if the mobile terminal is in a screen locking state at this time, the user to be added, whose facial feature information is determined to be feature information without unlocking authority, cannot immediately unlock the screen through face recognition.
When the mobile terminal returns to the hand of the master user again, if the mobile terminal is in the screen locking state, the master user can acquire face feature information of the master user by using the front camera of the mobile terminal, namely the mobile terminal can acquire second face information.
In step 302, the mobile terminal may determine whether the second face information matches the feature information in the face database. The feature information in the face database is face feature information of a master user, the master user is the first user who obtains face recognition unlocking authority, and the master user is the owner of the mobile terminal under normal conditions.
And 303, if the second face information is matched with the feature information in the face database, displaying the first face information.
In step 303, at this time, the mobile terminal may determine that the collected second face information matches with the feature information in the face database, so that the screen of the mobile terminal is unlocked, and it may be determined that the user currently operating the mobile terminal is the master user.
Next, the mobile terminal may display the first face information, for example, after the screen is unlocked, a prompt box may pop up, the first face information is displayed in the prompt box, and the first face information may be prompted by a character: "the user requests to obtain face recognition unlocking authority". An "effect button" and a "delete button" may also be displayed in the prompt box. Fig. 4 is a schematic diagram of a prompt box.
And 304, if the second face information is matched with the feature information in the face database and the authority adding operation is detected, adding the first face information serving as the feature information into the face database.
In step 304, if the master user agrees that the user to be added obtains the face recognition unlocking authority, the "validation button" in the prompt box may be clicked, and the mobile terminal may detect the authority addition operation.
And then the mobile terminal can add the first face information as feature information to the face database according to the detected authority adding operation. Namely, the mobile terminal can set the first face information as the feature information with the unlocking authority according to the detected authority adding operation. That is, the mobile terminal may determine the user to be added, whose facial feature information is determined to be feature information without unlocking authority, as a visitor user with face recognition unlocking authority according to the detected authority adding operation.
And 305, deleting the first face information when the information deleting operation is detected.
In step 305, if the master user does not agree that the user to be added obtains the face recognition unlocking authority, the "delete button" in the prompt box may be clicked, and the mobile terminal may detect the delete information operation. And the mobile terminal can delete the first face information according to the detected deletion information operation.
The face recognition method of the embodiment of the invention is applied to the mobile terminal. And only when the collected second face information is matched with the characteristic information in the face database, the first face information is added into the face database as the characteristic information. Further, after the first face information is determined to be the feature information without the unlocking authority, the master user can also determine whether to reset the first face information to be the feature information with the unlocking authority according to the own will. The risk of privacy disclosure can be effectively reduced, and the face recognition function is more perfect.
