Specifically, the graphical user interface may include: and the function control can be used for triggering the information verification request to be sent to the server.
For example, a current graphical user interface may be used to perform a user login function, the graphical user interface being exposed with functionality controls. After the user inputs login information through the graphical user interface, the function control can be clicked, so that the 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 the embodiment of the present application, the verification information may include: virtual object expression images and/or verification prompt information. The verification prompt information is used for prompting the association relation between the expression image of the virtual object and the verification requirement.
The virtual object expression image refers to a virtually generated face image, in order to protect privacy of a user, the virtual object expression image is different from a real face image, and in order to ensure a vivid effect of the virtual object expression image, the generated virtual object expression image can ensure enough face authenticity and naturalness.
The verification prompt information indicates a problem of generating the expression image of the virtual object, and the verification prompt information indicates a user to perform verification operation on a verification code containing the expression image of the virtual object.
For example, referring to fig. 3, fig. 3 is an application scenario schematic diagram 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: user information pages, verification pages, and functionality controls. The user information page is used for inputting user information by a user; the function control is used for triggering the information verification request to be sent 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 expression picture with the largest difference", that is, the verification requirement is: and selecting one or more virtual object expression images 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 of non-selected virtual object expression images is large. In fig. 3, the virtual object expression image sequentially includes, from left to right: the first virtual object expression image P1, the second virtual object expression image P2, and the third virtual object expression image P3. Further, when the user sees the verification prompt information of the current verification page: after selecting the expression picture with the largest difference, the user can select one or more virtual object expression pictures from the multiple virtual object expression pictures to obtain an operation result.
103. An operation result is generated 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 that an operation result is obtained.
In some embodiments, to enhance the user experience, the number of virtual object emoticons in the verification page may be multiple, and the multiple virtual object emoticons may be: the plurality of virtual object expression images with the expression difference exist, 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, meeting the specified condition refers to meeting the condition of verifying the prompt information. The step of generating an operation result based on the operation on the authentication page may include the following operations:

and obtaining an operation result based on the target virtual object expression image.
The selection operation refers to that the user selects the virtual object expression image in the verification page, for example, the user can click on the virtual object expression image in the verification page to select the virtual object expression image.
For example, with continued reference to fig. 3, the verification page shown in fig. 3 includes 3 virtual object expression images, which are respectively: the first virtual object expression image P1, the second virtual object expression image P2, and the third virtual object expression image P3. When the user sees the verification prompt information of the current verification page: after "please pick out the expression picture with the largest difference", the 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 larger, and the expression difference between the second virtual object expression image P2 and the third virtual object expression image P3 is also larger, so that the user can select the second virtual object expression image P2 as an answer to the verification prompt information, and the current user operation result is obtained.
For another example, referring to fig. 3, the verification page shown in fig. 3 includes 3 virtual object expression images, which are respectively: the first virtual object expression image P1, the second virtual object expression image P2, and the 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 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 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 a user can select the first virtual object expression image P1 and the third virtual object expression image P3 as answers to verification prompt information, and a current user operation result is obtained.
In some embodiments, to improve the user experience, the number of virtual object expression images in the verification page may be one, at which time the verification prompt may instruct the user to select an expression keyword matching the virtual object expression image from a plurality of expression keywords. The step of generating an operation result based on the operation on the authentication page may include the following operations:
responding to the selection operation of the user on a 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 keyword is used for representing an expression of the expression image of the virtual object, for example, the expression keyword may include: happy, angry, difficult, angry, crying, sad, 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 on the expression keyword in the verification page to select the expression keyword.
For example, referring to fig. 4, fig. 4 is a schematic application scenario diagram of another information verification method according to an embodiment of the present application. In the graphical user interface shown in fig. 4, there are: user information pages, verification pages, and functionality controls. The user information page is used for inputting user information by a user; the function control is used for triggering the information verification request to be sent 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 expression keywords matched with the following face images: ", 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 according to the verification prompt information of the verification page, and the expression keyword is used as a target expression keyword, and an operation result can be obtained according to the target expression keyword.
In some embodiments, to improve the user experience, the virtual object expression package image may include a plurality of virtual object expression images, and the verification prompt information may be used to prompt the user to select a virtual object expression image matching a preset expression keyword from the plurality of virtual object expression images. The step of generating an operation result 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 plurality of virtual objects in the verification page, and determining a target virtual object expression image from the expression images of the plurality of virtual objects;
and obtaining an operation result based on the target virtual object expression image.
The selection operation refers to that the user selects the virtual object expression image in the verification page, for example, the user can click on the virtual object expression image in the verification page to select the virtual object expression image.
For example, the verification page may include 3 virtual object expression images, which are respectively: the first virtual object expression image, the second virtual object expression image and the third virtual object expression image. When the clicking operation of the user on the first virtual object expression image is detected, the user can be determined to select the first virtual object expression image as a target virtual object expression image, and the first virtual object expression image is used as an answer to the verification prompt information, so that the 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 verification is performed on the operation result through the server.
Wherein, the verification result may include: the verification is successful or fails, the verification success indicates that the operation result is the same as the correct answer of the verification prompt information, and the verification failure indicates that the operation result 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 verification is successful, the verification code verification is completed, and then a function execution request of the current graphical user interface can be sent to the server, for example, the current graphical user interface executes user login, and then a user login request and the like are sent to the server.
In some embodiments, to improve the information verification efficiency, the method may further include the steps of:
If the verification result indicates that 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 aiming at 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, the image switching request indicates to acquire the expression image of the virtual object again from the server, and the expression image of the virtual object in the current terminal verification page is replaced for display.
For example, referring to fig. 5, fig. 5 is a schematic application scenario diagram of another information verification method according to an embodiment of the present application. In the verification page shown in FIG. 5, if the verification result can verify failure, then the display of "verification failure-!

Thus, the security of information verification can be improved.
The embodiment of the application provides another information verification method, which can be executed by a server or a terminal, and the embodiment of the application is described by taking the information verification method as an example of the execution of the information verification method by the terminal.
Referring to fig. 6, fig. 6 is a flowchart illustrating another information verification method according to an embodiment of the present application. The specific flow of the information verification method can be as follows:

In an embodiment of the present application, the graphical user interface may include: 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: selecting a virtual object expression image with similar facial expressions, or selecting a virtual object expression image with the largest facial expression difference in the virtual object expression images, and the like.
The verification prompt information is generated at the terminal, so that the pressure of the server side can be reduced, 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.

Further, the operation result is verified, namely, the operation result is compared with the correct answer of the verification prompt information, and the verification result can be obtained.
For example, if the operation result is the same as the correct answer of the verification prompt message, the verification result can be determined to be successful verification; if the operation result is different from 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 application provides another information verification method, which can be executed by a server or a terminal, and the embodiment of the application is described by taking the information verification method as an example.
Referring to fig. 7, fig. 7 is a flowchart illustrating another information verification method according to an embodiment of the present application. The specific flow of the information verification method can be as follows:
301. And responding to an information verification request sent by the terminal, and screening out the expression image of the virtual object from the image set.
The information verification request indicates the server to send verification codes, namely verification information, to the terminal, wherein the verification information at least comprises: virtual object expression image.
The image set comprises a plurality of virtual object expression images, wherein the virtual object expression images refer to virtual object expression images generated by a server, and the virtual object expression images are similar to the real face images but have differences.
In some embodiments, to protect the privacy information of the real user image, before the step of "screening 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;
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.
Where the sample noise data refers to the input of the image generation network, the sample noise data may be noise vectors that conform to a normal distribution, for example. And inputting the sample noise data into an image generation network, processing the sample noise data by using the image generation network, and outputting to obtain the expression image of the virtual object.
In the embodiment of the application, in order to ensure that the virtual object expression image has a difference from the real face image and simultaneously ensure the face authenticity and naturalness of the virtual object expression image, the virtual object expression image can be generated by using the generation countermeasure network model.
Specifically, the generation of the countermeasure network model mainly includes two parts: a model and a discriminant model are generated. The generation model refers to that data such as characters, images, videos and the like can be generated from input data according to tasks and through model training. The generating model is used for generating a model of the specified distribution data, and the generating model is used for capturing the distribution of sample data and converting the distribution condition of the original input information into samples of the specified distribution through parameter conversion in maximum likelihood estimation.
The discrimination model determines whether the data such as the image generated by the generation model is the data in the real training data.
Further, the generation model and the discrimination model in the generated countermeasure network model can play games with each other, and the simple mode of the games is as follows: generating a plurality of pictures- > distinguishing models by the generating models, learning and distinguishing the generated pictures and the real pictures- > generating models, performing model parameter adjustment according to the distinguishing models, generating new pictures- > distinguishing models, and then learning and distinguishing the generated pictures and the real pictures, so that the generating models become a perfect model until the model parameters of the generating models and the distinguishing models are optimal.
For example, referring to fig. 8, fig. 8 is a schematic view of a generated image scene of a method for information verification according to an embodiment of the present application. In fig. 8, the random noise may be: normally distributed noise data (i.e., unified class of distributed data, because the training model is converted by the distribution, the model functions to convert a class of distribution into the data distribution needed by the task). Firstly, noise data can be input into a generating network; noise data creates virtual image data through the generation network, and because the purpose of this embodiment is to make the authentication network as indistinguishable as possible from the image, model training is performed in conjunction with the authentication network, by which training the virtual image created by the generation network is more realistic.
The generated image output by the generation network and the real image are input into the authentication network, and then the final authentication result is obtained through the calculation of the model parameters of the authentication network, and the output can be: a parameter value between 0 and 1, 0 can represent a generated image, 1 can represent a real image, and for the generated image generated by the generating network, the discrimination network is expected to output an output value close to 0 as much as possible, so that the authenticity of the generated image can be effectively judged.
By generating the countermeasure network model in this embodiment, a plurality of virtual object expression images may be generated, resulting in an image set including the plurality of virtual object expression images.
In some embodiments, to ensure facial expression diversity of the virtual object expression image, the step of "obtaining the virtual object expression image from the virtual object expression image" may include the following operations:
determining a target facial expression, and extracting expression characteristic data of the target facial expression;
and fusing the expression image of the virtual object with the expression characteristic data to obtain the expression image of the virtual object corresponding to the expression image of the virtual object.
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: the expression keywords corresponding to the facial expression B may be: sadness, the expression keyword corresponding to the facial expression C may be: crying, etc.
Further, for the target facial expression, the expression feature data of the target facial expression can be extracted, and then a new virtual object expression image is generated based on the expression feature data and the sample virtual object expression image generated in the previous step, namely a processed facial image, wherein the processed facial image carries the target facial expression.
For example, referring to fig. 9, fig. 9 is a schematic view of a generated image scene of another method for verifying information 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 generating network, the generated image A fused with the target expression feature through the generating network is output to obtain a generated image B, and then the generated image B and the real image are identified through an identification network, and the identification process can be seen from the description. The generated image A refers to a sample virtual object expression image generated by the antagonistic network model, and the generated image B refers to a processed virtual object expression image fusing the target expression, so that a virtual object expression image with multiple expressions can be obtained.
In some embodiments, in order to ensure that the generated verification code brings good experience to the user, in the step of 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 of "screening out the expression image of the virtual object from the 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 sub-set;
and determining a target image subset from more than one image subset, and taking the virtual object expression images contained in the target image subset as the screened virtual object expression images.
Specifically, definition information and expression abnormality information of the expression image of each processed sample virtual object are obtained; screening the processed sample virtual object expression images in the image set based on the definition information and the expression anomaly information to obtain a plurality of target sample virtual object expression images; dividing expression images of multiple target sample virtual objects to obtain multiple image subsets.
The definition information includes the definition of the expression image of the virtual object, and in order to enable the 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 refers to the fact that the expression image of the virtual object cannot be identified, that is, no corresponding expression keyword exists. The expression anomaly information may include an expression keyword for each processed sample virtual object expression image.
Further, according to the definition information and the expression anomaly information, the images with the definition of the images in the processed sample virtual object expression images not meeting the preset definition and the images with the abnormal expression are removed, the remaining images with the definition meeting the preset definition and the images with the normal expression can be used as target virtual object expression images. And then dividing the expression image of the target virtual object to obtain a plurality of image subsets, wherein 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 of dividing the expression images of the virtual objects of the plurality of target samples 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 appointed number to obtain a plurality of candidate image subsets;
extracting expression feature vectors of each virtual object expression image;
calculating vector distance values between expression feature vectors of every two virtual object expression images in each candidate image subset;
a subset of images is determined from the plurality of subsets of candidate images based on the vector distance values.
In the embodiment of the present application, in order to ensure that the difficulty level of the verification code is moderate, the number of the specified virtual object expression images contained in each candidate image subset is: 3, in order to avoid that too many images take more time for the user to recognize.
Specifically, all the target sample virtual object expression images are combined according to the specified data, for example, the target sample virtual object expression images may include: the first virtual object expression image, the second virtual object expression image, the third virtual object expression image, the fourth virtual object expression image, and the like, then the target sample virtual object expression images are combined based on the specified number, and a first candidate image subset can be obtained, including: the first virtual object expression image, the second virtual object expression image and the third virtual object expression image; a second subset of candidate images, comprising: the second virtual object expression image, the third virtual object expression image and the fourth virtual object expression image; a third subset of candidate images, comprising: the first virtual object expression image, the second virtual object expression image and the fourth virtual object expression image; a fourth subset of candidate images, comprising: the first virtual object expression image, the third virtual object expression image and the fourth virtual object expression image.
The expression feature vector of the expression image of the virtual object of the extracted target sample can be extracted through the trained network model. Firstly, preprocessing an expression image of a virtual object of a target sample, including image cutting and the like, to obtain a processed image meeting the input condition of a network model, then inputting the processed image into a convolutional neural network model, extracting features, normalizing the extracted feature data, and finally obtaining an expression feature vector.
In the embodiment of the application, the trained network model can be composed of 30 layers of convolutional neural networks, training is completed on 400000 training sets, the SGD optimization algorithm is adopted to update parameters, the learning rate is 0.0002, 20 epochs (a period of forward transmission and reverse transmission of all training samples) are trained in total, and finally, the triple Loss is adopted as a Loss function. The final 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 smaller variability, such as faces, and the like, feed data comprise an Anchor (Anchor) example, a Positive (Positive) example and a Negative (Negative) example, and similarity calculation of the samples is achieved by optimizing the distance between the Anchor example and the Positive example to be 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, calculating a distance value between expression feature vectors of every two target sample virtual object expression images.
For example, a first subset of candidate images includes: the expression feature vectors of the first virtual object expression image may be: a, the expression feature vector of the second virtual object expression image 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: the distance ab, the distance value between the expression feature vectors of the first virtual object expression image and the third virtual object expression image may be: 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: distance bc.
In the embodiment of the application, in order to ensure that the virtual object expression images with larger expression differences exist in the image sub-sets so as to facilitate quick resolution, when the image sub-sets are determined, the virtual object expression images with larger expression differences and other virtual object expression images can be ensured to exist in the image sub-sets.
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, the candidate image subset may be determined to be an image subset, and may be used as a verification code.
In some embodiments, to filter out verification information that is convenient for a user to operate, the step of determining a subset of images from the plurality of candidate subsets of images based on the vector distance value may include the following operations:
determining a first virtual object expression image with the largest difference in the 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 among other virtual object expression images except the first virtual object expression image in the target candidate image subset, and second vector distance values among the first virtual object expression image and the other virtual object expression images in the target candidate image subset respectively;
and if the second vector distance values are all larger than the first vector distance value preset value, determining the target candidate image subset as the image subset.
For example, the target candidate image subset includes: the expression feature vectors of the first virtual object expression image may be: a, the expression feature vector of the second virtual object expression image 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: the distance ab, the distance value between the expression feature vectors of the first virtual object expression image and the third virtual object expression image may be: 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: distance bc.
Further, the vector values are compared with each other, a maximum distance value is screened out, and the expression image of the first virtual object 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 the target candidate image subsets with the second vector distance values being larger than the preset numerical value of the first vector distance values are combined into the image subset.
In some embodiments, to improve verification effectiveness, the step of "screening out a virtual object expression image from an image set" may include: screening a plurality of virtual object expression images from the image set; the verification prompt information is used for indicating a user to screen the 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 largest difference in the target image subset based on the vector distance value of the expression feature vector corresponding to each two virtual object expression images in the target image subset, and taking the virtual object expression image with the largest difference as a verification answer.
For example, in the target image subset, there are: the vector distance value of the first virtual object expression image and the second virtual object expression image obtained by calculating the first virtual object expression image, the second virtual object expression image and the third virtual object expression image 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 value is larger than the second value, the second value is larger than the third value, and the first virtual object expression image can be determined to be a verification answer.
In some embodiments, to improve verification effectiveness, the step of "screening out a virtual object expression image from an image set" may include: screening a plurality of virtual object expression images from the image set; the verification prompt information is used for indicating a user to screen the virtual object expression images with consistent expressions from the plurality of virtual object expression images;
the method may further comprise the steps of:
and determining the virtual object expression images with vector distance values within a preset range as verification answers based on the vector distance values of the expression feature vectors corresponding to the virtual object expression images in the target image subset.
For example, in the target image subset, there are: the vector distance value of the first virtual object expression image and the second virtual object expression image obtained by calculating the first virtual object expression image, the second virtual object expression image and the third virtual object expression image 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 a third value. If the first value and the second value are within the preset range, the first virtual object expression image and the second virtual object expression image can be determined to be verification answers.
In some embodiments, to meet different user requirements, a group of verification codes may be set to include a plurality of virtual object expression images, and then the step of "screening the virtual object expression images from the image set" may include the following operations:
determining a target image subset from the 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, a set of verification codes may be set to include a virtual object expression image, and the step of "screening the virtual object expression image from the image set" may include the following operations:
a virtual object expression image is determined from a plurality of sample virtual object expression images.
In this embodiment, there is no need to divide the image subset, so that processing resources can be saved, and after receiving the information verification request sent by the terminal, one virtual object expression image can be arbitrarily selected from the generated multiple sample virtual object expression images, so as to generate the verification code.
302. And sending the virtual object expression image and the verification prompt information to the terminal, 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.
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 plural, the verification prompt may instruct the user to select a face image with the largest difference among the expression images of the virtual object, or the verification prompt may instruct the user to select a face image with a similar expression in the expression images of the virtual object.
For another example, if the number of expression images of the virtual object is one, the verification prompt may instruct the user to select an expression keyword or the like that matches the expression image of the virtual object.
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. And then, sending the verification code to the terminal.
In some embodiments, to reduce the difficulty of user operation, the method may further include the steps of:
when an image switching request sent by a terminal is received, vector distance values between expression feature vectors of the expression images of the virtual objects in each image subset are obtained;
determining an image subset corresponding to the expression feature vector of the virtual object expression image with the largest difference of vector distance values;
and generating verification prompt information based on the virtual object expression images in the image sub-set, and sending the virtual object expression images 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, namely, reselects the image subset which does not comprise the expression image of the virtual object displayed by the current terminal from a plurality of image subsets.
Specifically, the vector distance value between the expression feature vectors of every two virtual object expression images in each image subset is obtained, the maximum vector distance value in each image subset is determined, and then the maximum vector distance values in each image subset are compared to obtain the maximum vector distance value, namely the maximum difference of the vector distance values. Therefore, the 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 user can easily distinguish the virtual object expression image with the largest vector distance value and the largest expression difference because of the largest distance value of the expression feature vector of the virtual object expression image in the subset.
Further, verification prompt information is generated based on the virtual object expression images in the image subset, and the virtual object expression images 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 pick out the expression picture with the largest difference; the virtual object expression image includes: the first virtual object expression image, the second virtual object expression image and the third virtual object expression image. The user can 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 information can be the first virtual object expression image, so that the operation result is the same as the correct answer of the verification prompt information, that is, the verification is successful.
For another example, the verification hint information may be: please pick out the expression picture with the largest difference; the virtual object expression image includes: the first virtual object expression image, the second virtual object expression image and the third virtual object expression image. The user can 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 information can be the first virtual object expression image, so that it can be determined that the operation result is different from the correct answer of the verification prompt information, that is, the verification failure is indicated. And then, feeding back the verification result to the terminal so that the user can continue to execute 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 verification is carried out 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, acquiring user information carried in the game acquisition request; 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 sending the game task to the terminal in response to the game acquisition request. The complexity of the short message verification code mode is avoided, and the convenience of the verification code operation mode is improved.
In light of the foregoing, 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 flow chart of another information verification method provided in the embodiment of the present application, where the information verification method is applied to interaction between a terminal and a server, and an application scenario is exemplified by a user registration scenario, and 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 user registration function.
Referring to fig. 11, fig. 11 is a schematic application scenario diagram of another information verification method according to an embodiment of the present application. In the user registration interface shown in fig. 10, it includes: the user information is entered into the page and registered with the 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 the personal information input of the user on the user information input page, the user can click a registration button to trigger the terminal to send a verification code acquisition request to the server.
402. The server receives the 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 the face images which exist in reality, so that privacy leakage of users is avoided.
When the server receives the verification code acquisition request sent by the terminal, any one image subset can be selected from a plurality of image subsets generated in advance, and a target image subset is obtained.
For example, the subset of images may include: the first subset of images, the second subset of images, and the third subset of images may be selected as the target subset of images when the verification code acquisition request is received.
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" or the like.
403. The server sends the virtual face image in the subset of images to the terminal, along with verification questions.
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 for verification operation.
404. And after receiving the virtual face image and the verification problem, the terminal displays the virtual face image and the verification problem on a verification page.
Referring to fig. 12, fig. 12 is a schematic application scenario diagram of another information verification method according to an embodiment of the present application. In the user registration page shown in fig. 12, a verification page is included, which shows: the first virtual face image, the second virtual face image and the third virtual face image, and the verification problem of 'please select face images with similar expressions'.
405. And the terminal selects a target virtual face image from the multiple 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, the user may click on the first virtual face image, and may indicate that the user selects 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 verify.
406. And the server verifies the target virtual face image, and if the verification is passed, the server registers the user information.
Specifically, when generating the verification question based on the virtual face image, the server determines the correct answer of the verification question.
For example, the verification problem is: please select face images with similar expressions. The user selectable virtual face image includes: the first virtual face image, the second virtual face image and the third virtual face image, and the correct answer may be: a first virtual face image. If the user selects the first virtual face image as the target virtual face image, the user is indicated to select a correct answer, and verification of the verification code is completed.
After the verification is successful, the server can finish the user information registration according to the user information.
According to the method and the device, a verification code acquisition request is sent to a server through registration operation of a user on a user registration interface at a terminal, when the server receives the verification code acquisition request, a target image subset is determined from a plurality of image subsets according to the verification code acquisition 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. After the terminal receives the virtual face image and the 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, the target virtual face image is sent to a server, finally, the server verifies the target virtual face image, and if the verification is passed, the registration of user information is executed. Thus, the security of information verification during user registration can be improved.
