Detailed Description
In order to make the technical solutions of the present application better understood, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. 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 application.
The inventor of the application finds that in the prior art, "face unlocking" is convenient to use, but certain potential safety hazards exist, for example, when a user intelligent terminal is robbed, a user is coerced, or other passive conditions exist, as long as the face of the user is aligned with a camera of the intelligent terminal, the screen of the intelligent terminal can be unlocked.
In order to solve the above problem, an embodiment of the present application provides a processing method based on face unlocking, and the method can make a user in a passive state unable to implement unlocking operation through face recognition, thereby reducing potential safety hazards.
Various non-limiting embodiments of the present application are described in detail below with reference to the accompanying drawings.
Exemplary method
Referring to fig. 1, the figure is a schematic flowchart of a processing method based on face unlocking according to an embodiment of the present application. The processing method based on face unlocking provided by the embodiment of the application can be executed by terminal equipment, wherein the terminal equipment includes but is not limited to smart devices such as smart phones and tablet computers.
The method provided by the embodiment of the application can comprise the following steps S101-S104.
S101: the terminal equipment acquires a face image of a user.
In the embodiment of the application, the terminal device can shoot the face image of the user by using the camera, so that the face image of the user is obtained. The user referred to herein refers to a legitimate user of the terminal device. Specifically, the terminal device may pre-store a face image of a valid user, so that the terminal device may determine that the user in the currently-photographed face image is the valid user of the terminal device according to the pre-stored face image.
S102: and the terminal equipment determines the expression of the user according to the facial image.
S103: and determining whether the user has unlocking intention according to the expression.
In the embodiment of the present application, it is considered that in practical applications, once a user is in a passive state, for example, a state of being coerced or the like. Illicit persons who coerce the user may force the user to unlock with a human face. In this case, a certain property loss may be caused to the user. The expression of the user when the unlocking is actively triggered and the expression of the user in a coerced state are considered to have a certain difference. In other words, the expression of the user may reflect whether the user has an unlocking intention. Therefore, in the embodiment of the application, the expression of the user can be recognized according to the facial image, and whether the user has the unlocking intention or not is further determined according to the determined expression.
In this embodiment of the application, in a specific implementation of S102, the terminal device may determine the expression of the user according to a pre-stored expression library, for example. Specifically, the expression library may include a plurality of facial images and expressions corresponding to the facial images. The terminal device may match the facial image acquired in S101 with an expression library, thereby determining the expression of the user.
After the expression of the user is determined, the terminal device may determine whether the user has the unlocking intention according to the corresponding relationship between the expression and the unlocking intention, for example. The correspondence between expressions and intentions can be understood in conjunction with table 1 below.
TABLE 1
| Expression of facial expressions | Intention to unlock |
| Smile (smile) | Having an intention of unlocking |
| Frown | Without intention of unlocking |
It should be noted that table 1 is shown only for convenience of understanding, and does not limit the embodiments of the present application. The expressions mentioned in the embodiment of the present application are not limited to "smile" and "frown" shown in table 1, and description thereof is not given here for other expressions.
S104: and the terminal equipment does not trigger unlocking operation when determining that the user does not have the unlocking intention.
In the embodiment of the application, when the terminal device determines that the user does not have the unlocking intention, the unlocking operation is not triggered. Therefore, when the user is in a passive state, unlocking operation cannot be realized through face recognition, and potential safety hazards are reduced.
In an implementation manner of the embodiment of the present application, it is considered that in practical application, although a user is in a passive state, the user cannot recognize the user through an expression of the user. For example, an illicit person forces the user to maintain a normal expression. When the user is in a passive state, for example, a duress state, the communication content between the user and illegal persons of the duress user can show that the user is in the passive state. In view of this, in some embodiments, the terminal device may also perform the steps shown in fig. 2. Fig. 2 is a flowchart illustrating a voice data processing method according to an embodiment of the present application. The method shown in fig. 2 can be implemented by the following steps S201 to S203.
S201: and under the condition that the user is determined to have the unlocking intention, the terminal equipment acquires voice data.
The user has the unlocking intention, which means that the user is determined to have the unlocking intention through the expression of the user. The terminal equipment can acquire the voice data through a voice acquisition device on the terminal equipment.
S202: and the terminal equipment determines whether the user is in a passive state or not according to the voice data.
In the embodiment of the application, after the terminal device acquires the voice data, semantic analysis can be performed on the voice data, so as to determine whether the user is in a passive state. Specifically, the terminal device may first convert the voice data into a text, then perform word segmentation processing on the text, and determine the semantics of the voice data according to a plurality of word segments obtained by word segmentation. After determining the semantics of the voice data, it may be determined whether the user is in a passive state. For example, the voice data is: and if not, the user is determined to be in a coerced state after voice analysis is carried out on the voice data.
S203: and the terminal equipment does not trigger unlocking operation when determining that the user is in the passive state.
The problem that potential safety hazards are brought when the terminal equipment is unlocked by face unlocking due to the fact that a user is forced is solved. In the embodiment of the application, when it is determined that the user is in the passive state through the voice data, the unlocking operation may not be triggered. Correspondingly, if the user is determined not to be in the passive state through the voice data, the unlocking operation is triggered.
In one implementation manner of the embodiment of the present application, it is considered that in practical applications, a user may be forced to use the mobile terminal. For this situation, when "determining that the user does not have the unlocking intention using S101 to S103" or "determining that the user is in the passive state using S201 to S202", the screen locking operation may be performed, so as to avoid a corresponding loss to the user due to an illegal person operating the terminal device.
In one implementation of the embodiment of the application, it is considered that some applications, such as mobile banking, which can perform property transactions, may be run on the terminal device. For convenience of description, these applications will be referred to as "target applications". In order to ensure the property security of the user, after determining that the user does not have the unlocking intention by using S101-S103, the account corresponding to the target application program can be frozen. Or when the user is determined to be in the passive state by using S201-S202, the account corresponding to the target application program is frozen. By adopting the method, illegal personnel can be prevented from operating the account, and property loss is brought to the user. It should be noted that, the account corresponding to the target application mentioned herein refers to an account operated by the user through the target application, for example, a certain bank card of the user.
