Referring to fig. 2, fig. 2 is a schematic flowchart illustrating another information verification method according to an embodiment of the present disclosure. The specific flow of the information verification method can be as follows:
101. and sending an information verification request to the server.
In the embodiment of the application, the information verification request can be sent to the server through the graphical user interface. The graphical user interface refers to an interface for executing related functions through user information, and the related functions may include multiple functions, such as user login, user registration, user information change, activity confirmation, login exception, user account password recovery, and the like. Accordingly, the graphical user interface refers to a user interface, such as a user login interface, a user registration interface, etc., that performs the above-described functions. The user login interface can complete the user login function through user information; the user registration interface can complete the user registration function through the user information. The graphical user interface may also implement more functions related to user information, which are not described herein in detail.
Wherein the verification information comprises a verification code that can be used to distinguish whether the operator is a computer or a public fully automated program of a person. The information authentication request instructs the server to transmit the authentication information to the terminal.
Specifically, the graphical user interface may include: and the function control can be used for triggering the sending of the information verification request to the server.
For example, current graphical user interfaces may be used to perform user login functions, with the graphical user interface exposed with functionality controls. After the user inputs the login information through the graphical user interface, the function control can be clicked, and therefore an information verification request is triggered to be sent to the server.
102. And when receiving the virtual object expression image and the verification prompt information returned by the server according to the information verification request, displaying a verification page on the graphical user interface according to the virtual object expression image and the verification prompt information.
In an embodiment of the present application, the verification information may include: the expression image of the virtual object and/or the verification prompt message. And the verification prompt information is used for prompting the association relationship between the expression image of the virtual object and the verification requirement.
The virtual object expression image refers to a virtually generated face image, the virtual object expression image is different from a real face image in order to protect privacy of a user, and meanwhile, the generated virtual object expression image can guarantee sufficient face reality and naturalness in order to guarantee the vivid effect of the virtual object expression image.
The verification prompt information refers to a problem generated through the expression image of the virtual object, and indicates a user to perform verification operation on a verification code containing the expression image of the virtual object.
For example, please refer to fig. 3, and fig. 3 is a schematic view illustrating an application scenario of a method for information verification according to an embodiment of the present application. In the graphical user interface shown in fig. 3, there are included: a user information page, a verification page, and a functionality control. The user information page is used for inputting user information by a user; the function control is used for triggering and sending an information verification request to the server; the verification page shows: and verifying the prompt information and the expression image of the virtual object. The verification prompt information may be "please select the most distinctive expression picture", that is, the verification requirement is: one or more virtual object expression images are selected from the virtual object expression images of the current verification page. The expression difference between the selected one or more virtual object expression images and the rest unselected virtual object expression images is larger. In fig. 3, the virtual object expression image includes, in order from left to right: a first virtual object expression image P1, a second virtual object expression image P2, and a third virtual object expression image P3. Further, when the user sees the verification prompt information of the current verification page: after "please select the expression picture with the largest difference", the user may select one or more virtual object expression images from the plurality of virtual object expression images to obtain an operation result.
103. And generating an operation result based on the operation on the verification page.
After the terminal displays the verification page, the user can operate the verification page. Specifically, the user can operate the content in the verification page according to the verification prompt information, so as to obtain an operation result.
In some embodiments, to improve the user experience, the number of virtual object expression images in the verification page may be multiple, and the multiple virtual object expression images may be: and at this time, the verification prompt information can instruct the user to screen the virtual object expression images meeting the specified conditions from the plurality of virtual object expression images. Wherein, the satisfaction of the specified condition refers to the satisfaction of the condition of the verification prompt information. The step "generate operation result based on operation on verification page" may include the following operations:
responding to the selection operation of a user on a plurality of virtual object expression images in the verification page, and determining a target virtual object expression image from the plurality of virtual object expression images;
and obtaining an operation result based on the expression image of the target virtual object.
The selection operation refers to the user selecting the virtual object expression image in the verification page, for example, the user may click the virtual object expression image in the verification page to select the virtual object expression image.
For example, with continuing reference to fig. 3, the verification page shown in fig. 3 includes 3 images of the expressions of the virtual object, which are respectively: a first virtual object expression image P1, a second virtual object expression image P2, and a third virtual object expression image P3. When the user sees the verification prompt information of the current verification page: after "please select the most different expression picture", a selection operation may be performed on the second virtual object expression image P2. In the first virtual object expression image P1, the second virtual object expression image P2, and the third virtual object expression image P3, the expression difference between the second virtual object expression image P2 and the first virtual object expression image P1 is large, and the expression difference between the second virtual object expression image P2 and the third virtual object expression image P3 is also large, so that the user can pick out the second virtual object expression image P2 as an answer to the verification prompt information, and obtain the current user operation result.
For another example, referring to fig. 3 again, the verification page shown in fig. 3 includes 3 virtual object expression images, which are respectively: a first virtual object expression image P1, a second virtual object expression image P2, and a third virtual object expression image P3. When the user sees the verification prompt information of the current verification page: after "please pick out similar expression pictures", the selection operation may be performed on the first virtual object expression image P1 and the third virtual object expression image P3. In the first, second, and third virtual object expression images P1, P2, and P3, the expression difference between the virtual object expression image P2 and the first virtual object expression image P1 is large, the expression difference between the virtual object expression image P2 and the third virtual object expression image P3 is also large, and the expression difference between the first virtual object expression image P1 and the third virtual object expression image P3 is small, so that the user can select the first virtual object expression image P1 and the third virtual object expression image P3 as answers to the verification prompt information, and obtain the current user operation result.
In some embodiments, in order to improve the user experience, the number of the virtual object expression images in the verification page may be one, and at this time, the verification prompt information may instruct the user to select an expression keyword matching the virtual object expression image from the plurality of expression keywords. The step "generate operation result based on operation on verification page" may include the following operations:
responding to the selection operation of a user on the plurality of expression keywords in the verification page, and determining a target expression keyword from the plurality of expression keywords;
and obtaining an operation result based on the target expression keywords.
The expression keywords are used to represent expressions of the expression images of the virtual object, and for example, the expression keywords may include: joy, anger, frustration, anger, cry, sadness, etc.
In this embodiment, the selection operation refers to that the user selects an expression keyword in the verification page, for example, the user may click the expression keyword in the verification page to select the expression keyword.
For example, referring to fig. 4, fig. 4 is a schematic view of an application scenario of another information verification method according to an embodiment of the present application. In the graphical user interface shown in fig. 4, there are included: a user information page, a verification page, and a functionality control. The user information page is used for inputting user information by a user; the function control is used for triggering and sending an information verification request to the server; the verification page shows: and verifying the prompt information and the expression image of the virtual object. The verification prompt information can be expression keywords matching with the following face images, and the expression keywords are selected from the verification prompt information: ", the virtual object expression image includes: the first virtual object expression image. The user can select one expression keyword from the plurality of expression keywords as a target expression keyword according to the verification prompt information of the verification page, and an operation result can be obtained according to the target expression keyword.
In some embodiments, in order to improve the user experience, the virtual object emoticon image may include a plurality of virtual object emoticon images, and the verification prompt information may be used to prompt the user to select a virtual object emoticon image matching the preset emoticon keyword from the plurality of virtual object emoticon images. The step "generating operation results based on the operation on the verification page" may include the following operations:
responding to the selection operation of a user on the expressions of the virtual objects in the verification page, and determining a target virtual object expression image from the plurality of virtual object expression images;
and obtaining an operation result based on the expression image of the target virtual object.
The selection operation refers to the user selecting the virtual object expression image in the verification page, for example, the user may click the virtual object expression image in the verification page to select the virtual object expression image.
For example, the verification page may include 3 images of the virtual object expression, which are: a first virtual object expression image, a second virtual object expression image, and a third virtual object expression image. When the clicking operation of the user on the first virtual object expression image is detected, the fact that the user selects the first virtual object expression image as the target virtual object expression image can be determined, the first virtual object expression image is used as a response to the verification prompt information, and a current user operation result is obtained.
104. And sending the operation result to the server so that the server verifies the operation result to obtain a verification result.
Further, an operation result of the user operating based on the verification page is sent to the server, and the operation result is verified through the server.
Wherein, the verification result may include: and if the verification is successful or the verification is failed, indicating that the operation result of the successful verification is the same as the correct answer of the verification prompt information, and indicating that the operation result of the failed verification is different from the correct answer of the verification prompt information.
105. And receiving a verification result sent by the server, and if the verification result indicates that the verification is successful, sending a function execution request of the graphical user interface to the server.
And after receiving the verification result sent by the server, judging whether the verification result is successful.
If the verification result is that the verification is successful, which indicates that the verification of the verification code is completed, a function execution request of the current graphical user interface may be sent to the server, for example, if the current graphical user interface executes user login, a user login request is sent to the server, and the like.
In some embodiments, to improve information verification efficiency, the method may further include the steps of:
if the verification result indicates that the verification fails, displaying an image switching control on a verification page;
responding to the triggering operation aiming at the image switching control, and sending an image switching request to a server;
and when receiving the virtual object expression image returned by the server for the image switching request, updating the verification page based on the virtual object expression image.
The image switching control is used for triggering the terminal to send an image switching request to the server, wherein the image switching request indicates to acquire the expression image of the virtual object from the server again and replace the expression image of the virtual object in the current terminal verification page for displaying.
For example, referring to fig. 5, fig. 5 is a schematic view of an application scenario of another information verification method according to an embodiment of the present application.

201. and sending an information verification request to the server through the graphical user interface.
In an embodiment of the present application, the graphical user interface may include: and the user can trigger the terminal to send an information verification request to the server through the operation of the function control, and the information verification request instructs the server to send the expression image of the virtual object to the terminal.
202. And when receiving the virtual object expression image returned by the server according to the information verification request, displaying a verification page on the graphical user interface according to the virtual object expression image.
Further, when the terminal receives the virtual object expression image returned by the server for the information verification request, verification prompt information can be generated according to the virtual object expression image.
For example, when the server returns a plurality of virtual object expression images according to the verification information request, the terminal may generate verification prompt information according to facial expressions of the plurality of virtual object expression images, for example, the verification prompt information may be: and selecting a virtual object expression image with similar facial expression, or selecting a virtual object expression image with the largest facial expression difference in the virtual object expression image, and the like.
The verification prompt information is generated at the terminal, so that the pressure of the server side can be relieved, and on the other hand, the data transmission quantity between the server and the terminal can be reduced, and the data transmission speed is improved, so that the verification of the verification information can be completed quickly.

For example, if the operation result is the same as the correct answer of the verification prompt message, the verification result may be determined to be successful; if the operation result is not the same as the correct answer of the verification prompt message, the verification result can be determined to be verification failure.
204. And if the verification result indicates that the verification is successful, sending a function execution request of the graphical user interface to the server.

The embodiment of the present application provides another information verification method, which can be executed by a server or a terminal, and the information verification method is executed by the server as an example in the embodiment of the present application.
Referring to fig. 7, fig. 7 is a flowchart illustrating another information verification method according to an embodiment of the present disclosure. The specific flow of the information verification method can be as follows:
301. and screening out the expression image of the virtual object from the image set in response to the information verification request sent by the terminal.
Wherein, the information verification request instructs the server to send the verification code, namely the verification information, to the terminal, and the verification information at least includes: the virtual object expression image.
The image set comprises a plurality of virtual object expression images, the virtual object expression images refer to virtual object expression images generated by the server, and the virtual object expression images are similar to real face images but have differences.
In some embodiments, in order to protect the privacy information of the real user image, before the step "filtering out the expression image of the virtual object from the image set", the following steps may be further included:
collecting sample noise data;
generating a virtual object expression image based on the sample noise data;
and obtaining a virtual object expression image according to the virtual object expression image, and obtaining an image set based on the virtual object expression image.
The sample noise data refers to an input of the image generation network, and for example, the sample noise data may be a noise vector conforming to a normal distribution. The sample noise data is input into an image generation network, the image generation network is utilized to process the sample noise data, and the virtual object expression image is output.
In the embodiment of the application, in order to ensure that the expression image of the virtual object is different from the real face image and ensure the face reality and naturalness of the expression image of the virtual object, the generation confrontation network model can be used for generating the expression image of the virtual object.
Specifically, the generation of the countermeasure network model mainly comprises two parts: generating a model and a discriminant model. The generation of the model means that data such as characters, images and videos can be generated from input data through model training according to tasks. The generated model is used for generating a model of the specified distribution data, and the generated model has the functions of capturing the distribution of the sample data and converting the distribution condition of the original input information into the sample of the specified distribution through parameter conversion in the maximum likelihood estimation.
The discrimination model determines data such as an image generated by the generation model, and determines whether the data is data in real training data.
Further, the generation model and the discrimination model in the generation countermeasure network model can play a game with each other, and the simple mode of the game is as follows: the generated model generates a plurality of pictures- > distinguishing the pictures generated by the model learning and distinguishing and the real pictures- > the generated model adjusts the model parameters according to the distinguishing model to generate a new picture- > distinguishing the model and then learns and distinguishes the generated pictures and the real pictures, and therefore the generated model can become a perfect model until the model parameters of the generated model and the distinguishing model are optimal.
For example, please refer to fig. 8, fig. 8 is a schematic diagram of an image scene generated by a method for information verification according to an embodiment of the present disclosure. In fig. 8, the random noise may be: normally distributed noise data (i.e., uniform class-one distribution data, since the training model is transformed according to the distribution, the model functions to transform the class-one distribution into the data distribution required by the task). Noise data may first be input into the generation network; the noise data can generate virtual image data through the generating network, and because the aim of the embodiment is to make the images which cannot be distinguished by the identifying network as far as possible, the embodiment can combine the identifying network to carry out model training, so that the virtual image effect generated by the generating network is more vivid through the training.
The generated image output by the generated network and the real image are input into the identification network, and then the final identification result output is obtained through the model parameter calculation of the identification network, and the output can be: the parameter value between 0 and 1, 0 can represent the generated image, 1 can represent the real image, and for the generated image generated by the generating network, it is desirable to identify that the network can output an output value close to 0 as much as possible so as to effectively judge whether the generated image is true or false.
By generating the confrontation network model in this embodiment, a plurality of virtual object expression images can be generated, and an image set including the plurality of virtual object expression images is obtained.
In some embodiments, in order to ensure the facial expression diversity of the expression image of the virtual object, the step "obtaining the expression image of the virtual object according to the expression image of the virtual object" may include the following operations:
determining a target facial expression, and extracting expression characteristic data of the target facial expression;
and fusing the virtual object expression image and the expression characteristic data to obtain a virtual object expression image corresponding to the virtual object expression image.
The target facial expression refers to a facial image with the target facial expression, a plurality of target facial expressions can be obtained from a facial database, and different target facial expressions correspond to different expression keywords.
For example, the target facial expression may include: facial expression A, facial expression B, facial expression C and the like. The expression keywords corresponding to the facial expression a may be: for the sake of mind, the expression keywords corresponding to the facial expression B may be: sadness, the expression keyword corresponding to the facial expression C may be: cry, etc.
Further, for the target facial expression, expression feature data of the target facial expression may be extracted, and then a new virtual object expression image, that is, a processed facial image, is generated based on the expression feature data and the sample virtual object expression image generated in the previous step, where the processed facial image carries the target facial expression.
For example, please refer to fig. 9, fig. 9 is a schematic diagram of an image scene generated by another information verification method according to an embodiment of the present application. The target expression image refers to an image with a target expression, and the target expression image is processed through an expression feature extraction network, so that the target expression feature of the target expression image can be extracted. Further, the target expression feature and the generated image a are used as input of a generation network, the target expression feature is fused by the generation network to generate the image a, a generated image B is obtained by output, and then the generated image B and the real image are identified by an identification network, wherein the identification process can refer to the above description. The generation image A refers to a sample virtual object expression image generated by generating a confrontation network model, and the generation image B refers to a processed virtual object expression image with a fusion target expression, so that virtual object expression images with various expressions can be obtained.
In some embodiments, in order to ensure that the generated verification code brings a good experience to the user, in the step "obtaining the image set based on the expression image of the virtual object", the method may further include the following steps:
and screening the virtual object images according to the definition of the virtual object expression images and/or the abnormal information of the virtual object expression images to obtain a screened image set.
Specifically, in order to improve the user experience, the step "filtering out a virtual object expression image from an image set" may include the following operations:
grouping the expression images of the virtual objects in the image set to obtain more than one image subset;
and determining a target image subset from more than one image subsets, and taking the virtual object expression images contained in the target image subset as the screened virtual object expression images.
Specifically, acquiring definition information and expression abnormal information of the expression image of each processed sample virtual object; screening the processed sample virtual object expression images in the image set based on the definition information and the expression abnormal information to obtain a plurality of target sample virtual object expression images; and dividing the expression images of the target sample virtual objects to obtain a plurality of image subsets.
The definition information includes the definition of the expression image of the virtual object, and in order to enable a user to clearly identify the expression image of the virtual object, the expression image of the virtual object with lower definition needs to be removed.
The expression abnormality means that the expression image of the virtual object cannot be identified, that is, no corresponding expression keyword exists. The expression anomaly information may include expression keywords of each processed sample virtual object expression image.
Further, according to the definition information and the expression abnormal information, the image definition in the expression image of the processed sample virtual object does not meet the preset definition and the image with the abnormal expression is removed, the remaining image definition meets the preset definition, and the image with the normal expression can be used as the expression image of the target virtual object. Then, the expression image of the target virtual object is divided, so that a plurality of image subsets can be obtained, and each image subset can be used as a group of verification codes for verifying the user.
In some embodiments, to improve the user experience, the step "dividing the target sample virtual object expression images to obtain a plurality of target image subsets" may include the following operations:
grouping the expression images of the virtual objects in the image set according to the specified number to obtain a plurality of candidate image subsets;
extracting expression characteristic vectors of expression images of each virtual object;
calculating a vector distance value between expression characteristic vectors of every two virtual object expression images in each candidate image subset;
an image subset is determined from a plurality of candidate image subsets based on the vector distance values.
In this embodiment of the present application, in order to ensure that the difficulty level of the verification code is moderate, the specified number may be designed as: 3, to avoid that too many images take more time for the user to recognize.
Specifically, all target sample virtual object expression images are combined according to the designated data, for example, the target sample virtual object expression images may include: combining the target sample virtual object expression images based on the specified number to obtain a first candidate image subset, including: a first virtual object expression image, a second virtual object expression image, and a third virtual object expression image; a second subset of candidate images comprising: a second virtual object expression image, a third virtual object expression image, and a fourth virtual object expression image; a third subset of candidate images comprising: a first virtual object expression image, a second virtual object expression image, and a fourth virtual object expression image; a fourth subset of candidate images comprising: a first virtual object expression image, a third virtual object expression image, and a fourth virtual object expression image.
The expression feature vectors of the expression images of the target sample virtual object are extracted, and the image features can be extracted through the trained network model. Firstly, preprocessing a target sample virtual object expression image, including image cutting and the like, to obtain a processed image meeting the network model input condition, then inputting the processed image into a convolutional neural network model, performing feature extraction, performing normalization processing on extracted feature data, and finally obtaining an expression feature vector.
In the embodiment of the application, the trained network model may be formed by 30 layers of convolutional neural networks, training is completed on a training set with the number of 400000, an SGD optimization algorithm is used to update parameters, the learning rate is 0.0002, a total of 20 epochs (a period of forward transfer and a period of reverse transfer of all training samples) are trained, and finally a Triplet Loss is used as a Loss function. Finally, the trained network model can output a low-dimensional expression characterization vector for each input image.
The triple Loss is a Loss function in deep learning and is used for training samples with small differences, such as human faces and the like, Feed data comprises an Anchor (Anchor) example, a Positive (Positive) example and a Negative (Negative) example, and similarity calculation of the samples is achieved by optimizing that the distance between the Anchor example and the Positive example is smaller than the distance between the Anchor example and the Negative example.
Further, for the target sample virtual object expression images in each candidate subset, a distance value between expression feature vectors of every two target sample virtual object expression images is calculated.
For example, a first subset of candidate images includes: the expression feature vector of the first virtual object expression image can be: a, the expression feature vector of the expression image of the second virtual object may be: b, the expression feature vector of the expression image of the third virtual object may be: c. further, the distance value between the expression feature vectors of the first virtual object expression image and the second virtual object expression image obtained by calculation may be: and the distance value between the expression feature vectors of the first virtual object expression image and the third virtual object expression image can be: and the distance ac, the distance value between the expression feature vectors of the second virtual object expression image and the third virtual object expression image may be: a distance bc.
In the embodiment of the application, in order to ensure that the virtual object expression image with larger expression difference exists in the image subset so as to be distinguished quickly, when the image subset is determined, the virtual object expression image with larger expression difference than other virtual object expression images can be ensured to exist in the image subset.
For example, a preset distance value may be set, the distance between the expression images of the virtual objects in the candidate image subset is compared with the preset distance value, and if there are expression feature vectors of two expression images of the virtual objects greater than the preset distance value, it may be determined that the candidate image subset is combined into an image subset, which may be used as the verification code.
In some embodiments, in order to filter out verification information that facilitates user operation, the step "determining a subset of images from a plurality of candidate subsets of images based on vector distance values" may include the following operations:
determining a first virtual object expression image with the largest difference in a target candidate image subset based on vector distance values of expression feature vectors corresponding to every two virtual object expression images in the target candidate image subset in the plurality of candidate image subsets;
acquiring first vector distance values between other virtual object expression images except the first virtual object expression image in the target candidate image subset and second vector distance values between the first virtual object expression image and other virtual object expression images in the target candidate image subset respectively;
and if the second vector distance values are all larger than the preset value of the first vector distance value, determining that the target candidate image subset is combined into the image subset.
For example, the target candidate image subset includes: the expression feature vector of the first virtual object expression image can be: a, the expression feature vector of the expression image of the second virtual object may be: b, the expression feature vector of the expression image of the third virtual object may be: c. further, the distance value between the expression feature vectors of the first virtual object expression image and the second virtual object expression image obtained by calculation may be: and the distance value between the expression feature vectors of the first virtual object expression image and the third virtual object expression image can be: and the distance ac, the distance value between the expression feature vectors of the second virtual object expression image and the third virtual object expression image may be: a distance bc.
Further, the anisotropic values are compared with each other, a maximum distance value is screened out, and the first virtual object expression image can be determined according to the maximum distance value. Then, a first vector distance value between other virtual object expression images except the first virtual object expression image in the target candidate image subset and a second vector distance value between the first virtual object expression image and each other virtual object expression image are calculated.
And taking the target candidate image subset with the second vector distance values larger than the preset numerical value of the first vector distance value as an image subset.
In some embodiments, to improve validation effectiveness, the step of "screening out a virtual object expression image from the image set" may include: screening a plurality of virtual object expression images from the image set; the verification prompt information is used for instructing a user to screen a virtual object expression image with the largest expression difference from the plurality of virtual object expression images;
the method may further comprise the operations of:
and determining the virtual object expression image with the maximum difference in the target image subset based on the vector distance value of the expression characteristic vector corresponding to every two virtual object expression images in the target image subset, and taking the virtual object expression image with the maximum difference as a verification answer.
For example, the subset of target images includes: the vector distance value of the first virtual object expression image and the second virtual object expression image obtained by calculation may be: a first value; the vector distance value between the first virtual object expression image and the third virtual object expression image may be: a second value; the vector distance value between the third virtual object expression image and the second virtual object expression image may be: and if the first numerical value is larger than the second numerical value and the second numerical value is larger than the third numerical value, determining the first virtual object expression image as a verification answer.
In some embodiments, to improve validation effectiveness, the step of "screening out a virtual object expression image from the image set" may include: screening a plurality of virtual object expression images from the image set; the verification prompt information is used for instructing a user to screen virtual object expression images with consistent expressions from the multiple virtual object expression images;
the method may further comprise the steps of:
and determining the virtual object expression image with the vector distance value within a preset range as a verification answer based on the vector distance value of the expression characteristic vector corresponding to every two virtual object expression images in the target image subset.
For example, the subset of target images includes: the vector distance value of the first virtual object expression image and the second virtual object expression image obtained by calculation may be: a first value; the vector distance value between the first virtual object expression image and the third virtual object expression image may be: a second value; the vector distance value between the third virtual object expression image and the second virtual object expression image may be: a third value. If the first numerical value and the second numerical value are within the preset range, the first virtual object expression image and the second virtual object expression image can be determined as verification answers.
In some embodiments, in order to meet different user requirements, it may be set that a plurality of expression images of the virtual object are included in a group of verification codes, and then the step "sift out the expression images of the virtual object from the image set" may include the following operations:
determining a target image subset from a plurality of image subsets;
and taking the target sample virtual object expression image in the target image subset as a virtual object expression image.
For example, after receiving an information verification request sent by a terminal, a group of image subsets can be arbitrarily selected from the image sets, and a target sample virtual object expression image in the target image subset is used as a virtual object expression image to generate a verification code.
Alternatively, in some embodiments, it may be set that the set of verification codes includes a virtual object expression image, and the step "sift out the virtual object expression image from the image set" may include the following operations:
a virtual object expression image is determined from the plurality of sample virtual object expression images.
In this embodiment, the image subset does not need to be divided, processing resources can be saved, and after an information verification request sent by the terminal is received, one virtual object expression image can be arbitrarily selected from the generated plurality of sample virtual object expression images to generate the verification code.
302. And sending the expression image of the virtual object and the verification prompt information to the terminal so that the terminal displays a verification page on the graphical user interface according to the expression image of the virtual object and the verification prompt information.
And the verification prompt information is used for prompting the association relation between the expression image of the virtual object and the verification requirement.
Further, after determining the virtual object expression image, verification prompt information may be generated according to the virtual object expression image.
For example, if the number of the expression images of the virtual object is multiple, the verification prompt information may instruct the user to select the facial image with the largest difference from the expression images of the virtual object, or the verification prompt information may instruct the user to select the facial image with similar expression from the expression images of the virtual object.
For another example, if the number of virtual object expression images is one, the verification prompt information may instruct the user to select an expression keyword or the like that matches the virtual object expression image.
Further, the virtual object expression image and the verification prompt information are sent to the terminal in response to the information verification request, so that the terminal displays a verification page on the graphical user interface according to the virtual object expression image and the verification prompt information.
After the face image is determined and the verification prompt information is generated according to the face image, the current verification code including the face image and the verification prompt information can be determined. The authentication code is then sent to the terminal.
In some embodiments, to reduce the difficulty of the user operation, the method may further include the steps of:
when an image switching request sent by a terminal is received, acquiring a vector distance value between every two expression characteristic vectors of the expression images of the virtual object in each image subset;
determining an image subset corresponding to expression feature vectors of the virtual object expression images with the largest difference of vector distance values;
and generating verification prompt information based on the virtual object expression image in the image subset, and sending the virtual object expression image and the verification prompt information to the terminal.
The image switching request instructs the server to resend the expression image of the virtual object to the terminal, that is, reselects the image subset which does not include the expression image of the virtual object displayed by the current terminal from the plurality of image subsets.
Specifically, a vector distance value between expression feature vectors of every two virtual object expression images in each image subset is obtained, a maximum vector distance value in each image subset is determined, then the maximum vector distance values in each image subset are compared, and a maximum vector distance value is obtained, namely, the vector distance value difference is maximum. Therefore, an image subset corresponding to the expression feature vector of the virtual object expression image with the largest vector distance value difference can be obtained, and the expression feature vector of the virtual object expression image in the subset has the largest distance value and the largest expression difference, so that the user can easily distinguish the images.
Further, verification prompt information is generated based on the virtual object expression image in the image subset, and the virtual object expression image and the verification prompt information are sent to the terminal.
In some embodiments, to ensure that the user continues to perform the relevant task, the method may further comprise the steps of:
when an operation result sent by a terminal is received, verifying the operation result to obtain a verification result, wherein the operation result is an operation result of a user operating a verification page;
and sending the verification result to the terminal.
For example, the verification hint information may be: please select the most distinctive facial expression picture; the virtual object expression image includes: a first virtual object expression image, a second virtual object expression image, and a third virtual object expression image. The user may select the first virtual object expression image as the target virtual object expression image, that is, the operation result is the first virtual object expression image, and the correct answer of the verification prompt message may be the first virtual object expression image, and then it may be determined that the operation result is the same as the correct answer of the verification prompt message, that is, the verification is successful.
For another example, the verification hint information may be: please select the most distinctive facial expression picture; the virtual object expression image includes: a first virtual object expression image, a second virtual object expression image, and a third virtual object expression image. The user may select the second virtual object expression image as the target virtual object expression image, that is, the operation result is the first virtual object expression image, and the correct answer of the verification prompt message may be the first virtual object expression image, and then it may be determined that the operation result is different from the correct answer of the verification prompt message, that is, the verification fails. And then, feeding back the verification result to the terminal so that the user can continuously perform subsequent operations.
303. And receiving an operation result sent by the terminal.
The operation result can be generated according to the operation of the user on the verification page, and then the verification is performed on the operation result, so that the operation result can be obtained.
The embodiment of the application discloses an information verification method, which comprises the following steps: when a game acquisition request sent by a terminal is received, user information carried in the game acquisition request is acquired; determining a target game matched with the user information from a preset game set, wherein the preset game set comprises a plurality of preset games; determining a game task based on the target game; and responding to the game acquisition request to send the game task to the terminal. The complexity of a short message verification code mode is avoided, and the convenience of a verification code operation mode is improved.
Based on the above description, the method of information verification of the present application will be further described below by way of example. Referring to fig. 10, fig. 10 is a schematic flowchart of another information verification method provided in the embodiment of the present application, taking the information verification method as applied to interaction between a terminal and a server, and taking an application scenario as a user registration scenario as an example, a specific flow may be as follows:
401. and the terminal sends a verification code acquisition request to the server through the registration operation of the user on the user registration interface.
The user registration interface is used for implementing the function of executing user registration.
Referring to fig. 11, fig. 11 is a schematic view of an application scenario of another information verification method according to an embodiment of the present application. In the user registration interface shown in fig. 10, the following are included: user information input page, register control. The user information input page is used for inputting personal information by a user, and the registration control is used for sending a verification code acquisition request to the server. After the user finishes inputting the personal information of the user on the user information input page, the user can click a registration button to trigger the terminal to send an authentication code acquisition request to the server.
402. The server receives a verification code acquisition request, determines a target image subset from the plurality of image subsets according to the verification code acquisition request, and generates a verification problem based on the virtual face image in the image subset.
Each image subset comprises at least one virtual face image, the virtual face images can be generated in advance, and the virtual face images do not comprise face images which exist really, so that privacy disclosure of users is avoided.
When the server receives a verification code acquisition request sent by the terminal, any one image subset can be selected from a plurality of pre-generated image subsets to obtain a target image subset.
For example, the subset of images may include: the first image subset, the second image subset and the third image subset may be selected to be a target image subset when receiving a request for acquiring a verification code.
Further, virtual face images in the target image subset are obtained, verification problems (equivalent to verification prompt information) are generated according to the virtual face images, and the verification problems can be generated according to the number of the virtual face images in the target image subset. For example, if there are multiple virtual face images in the target image subset, the verification problem may be "please select face images with similar expressions", and so on.
403. And the server sends the virtual face images in the image subset to the terminal and verifies the problem.
After the server determines the virtual face image and generates the verification problem according to the virtual face image, the virtual face image and the verification problem can be sent to the terminal to perform verification operation.
404. And after the terminal receives the virtual face image and the verification problem, displaying the virtual face image and the verification problem on a verification page.

In the user registration page shown in fig. 12, a verification page is included, which shows: the face image verification method comprises the steps of obtaining a first virtual face image, a second virtual face image, a third virtual face image and a verification problem, wherein the verification problem is 'please select face images with similar expressions'.
405. And the terminal selects a target virtual face image from the plurality of virtual faces according to the selection operation of the user on the verification page and sends the target virtual face image to the server.
The user may perform a selection operation on the virtual face image displayed on the verification page, for example, if the user can click the first virtual face image, the user may select the first virtual face image as the target virtual face image. The terminal may then send the user selection to the server to cause the server to authenticate.
406. And the server verifies the target virtual face image, and if the verification is passed, the server registers the user information.
Specifically, when the server generates the verification question based on the virtual face image, the server determines the correct answer of the verification question at the same time.
For example, the verification problem is: please select face images with similar expressions. The user-selectable virtual face images include: the correct answers of the first virtual face image, the second virtual face image and the third virtual face image can be as follows: a first virtual face image. And if the user selects the first virtual face image as the target virtual face image, the user selects a correct answer to complete verification of the verification code.
And when the verification is successful, the server can complete the user information registration according to the user information.
According to the method and the device, a verification code obtaining request is sent to a server through the registration operation of a user on a user registration interface at a terminal, when the server receives the verification code obtaining request, a target image subset is determined from a plurality of image subsets according to the verification code obtaining request, verification problems are generated based on virtual face images in the image subsets, and then the server sends the virtual face images in the image subsets and the verification problems to the terminal. The method comprises the steps that after a terminal receives a virtual face image and a verification problem, the virtual face image and the verification problem are displayed on a verification page, the terminal selects a target virtual face image from a plurality of virtual faces according to the selection operation of a user on the verification page and sends the target virtual face image to a server, finally, the server verifies the target virtual face image, and if the verification is passed, user information is registered. Therefore, the safety of information verification during user registration can be improved.
