The process for the validation-cross method based on identifying code that Fig. 2 schematically shows according to an embodiment of the invention Figure.
As shown in Fig. 2, this method is applied to server, it may include following operation S201~S205.
S201 is operated, in response to checking request, obtains identifying code parameter.
In this operation S201, checking request is grasped from client, such as client end response in login, registration, access etc. Whether it is real user to verify the operation side currently operated when making, therefore sends checking request to server.Server is rung Identifying code parameter should be obtained from local or third party device, the identifying code parameter is for generating verifying symbol in the checking request Element, so that subsequent client shows the verifying data code, and it is current by determining for the identification situation of the verifying data code It is machine or real user in the operation side that client is operated.
S202 is operated, identifying code parameter and three-dimensional model generator is based on, generates at least one three-dimensional verification code element.
Wherein, three-dimensional model generator is obtained based on generation confrontation network training, generates confrontation network in structure By the inspiration of the zero-sum two-person game in game theory, it is made of a generator and an arbiter.Generator captures true number According to the potential distribution of sample, and generate new data sample.Arbiter differentiates that input is the data sample of truthful data or generation This.It generates confrontation network to be learnt by way of allowing generator and arbiter to carry out game, target is to reach Nash Equilibrium. Three-dimensional model generator in this operation S202 is to obtain via above-mentioned learning process.Three-dimensional verification code element is different from existing There is the two dimensional image identifying code in technology, is the pictorial element with 3 d pose information, the difficulty of machine recognition can be increased.
S203 is operated, at least one above-mentioned three-dimensional verification code element is sent to client and is shown.
S204 is operated, attribute relevant to the interactive operation of at least one above-mentioned three-dimensional verification code element is directed to is obtained and believes Breath.
Wherein, attribute information relevant to the interactive operation of at least one above-mentioned three-dimensional verification code element is directed to is able to reflect Identification situation of the operation policy of interactive operation at least one above-mentioned three-dimensional verification code element out.
S205 is operated, the attribute information is based on, determines the interactive operation for being directed at least one above-mentioned three-dimensional verification code element Whether verifying is passed through.
Wherein, when attribute information relevant to interactive operation shows that the operation side of current authentication can identify above-mentioned at least one When a three-dimensional verification code element, determine that the interactive operation by verifying, confirms that the operation side is real user.Conversely, working as and friendship When the relevant attribute information that interoperates shows that the operation side of current authentication cannot identify at least one above-mentioned three-dimensional verification code element, It determines that the interactive operation is unverified, confirms that the operation side is machine.
It will be understood by those skilled in the art that method shown in Fig. 2 is when the operation for needing verifying to be operated in client When whether side is real user, identifying code parameter is obtained, and obtain three-dimensional model generator based on confrontation network training is generated.Again At least one three-dimensional verification code element is generated based on identifying code parameter and three-dimensional model generator so that client is shown.Visitor When showing at least one three-dimensional verification code element, guidance current operation policy is at least one three-dimensional verification code member at family end Element executes interactive operation.Determined further according to attribute information relevant to the interactive operation current operation side for this at least one The identification situation of three-dimensional verification code element, and then determine whether current operation side is real user, i.e., whether passes through verifying.The mistake Journey compared with the prior art in the scheme verified using two dimensional image identifying code, given birth to based on identifying code parameter and threedimensional model The three-dimensional verification code low but high for machine recognition difficulty for real user identification difficulty can accurately and effectively be generated by growing up to be a useful person Element improves the safety that verifying is interacted based on identifying code.
Illustratively, to obtain the above three-dimensional verification code element for being verified, training in advance is needed to obtain three Dimension module generator.In one embodiment of the present disclosure, according to the validation-cross side based on identifying code of the embodiment of the present disclosure Method further can also include: firstly, the generation confrontation net that creation is made of a shape generator and a shape discrimination device Network.Wherein shape generator is for generating voxel grid, and the voxel grid is for characterizing certain shape, and shape is sentenced Other device is for differentiating that the voxel grid is the image of true picture or generation.Then, the X-Y scheme of the first quantity is utilized Input of the decent shape coding as shape generator, using the voxel grid model of shape generator output as shape The input of shape arbiter, the differentiation result based on the output of shape discrimination device optimizes the parameter of shape generator, and is based on The true three-dimension model sample of second quantity optimizes the parameter of the shape discrimination device.Alternative optimization shape is raw like this The parameter grown up to be a useful person with shape discrimination device obtains optimised shape generator until the loss function for generating confrontation network reaches convergence With optimised shape arbiter.So far, training process terminates.Will the obtained optimised shape generator of training as above generating three Three-dimensional model generator needed for dimension verifying data code.
The Essential Action of above-mentioned three-dimensional model generator be based on collect come two dimensional image sample, three-dimensional mould can be made Type.Above-mentioned training process generates confrontation network for the shape of any one two dimensional image essentially by one shape of study Coding mapping is to a voxel grid model, i.e., study is directed to the 3D shape of certain object from a large amount of shape set Prior Template, these Prior Templates are only related to kind of object, independent with other factors (such as visual angle, the factors such as texture).It is above-mentioned The process for learning a shape generation confrontation network will train a shape generator and a shape discrimination device simultaneously, such as can To be carried out as follows.
A generation model is defined as shape generator Gshape, can be to shape generator GshapeInput an image Coding vector exports as voxel grid model.Also, a classifier is defined as shape discrimination device Dshape, for sentencing Other voxel grid model is genuine (the true 3D model sample in data set) or false (by shape generator GshapeThe voxel grid model of generation).It can be with random initializtion shape generator GshapeWith shape discrimination device DshapeGinseng Number.
Then, prepare the set { v of the 3D model sample v of one group of true 3D object1, v2..., vN}.Regather one group of 2D Image pattern, and be distributed according to 2D image pattern, uniformly generate shape coding zshapeSet { z1, z2..., zN, shape is raw Growing up to be a useful person can be according to each shape coding zshape(being represented by shape coding vector) generates one having a size of W × W × W solid Pixel grid model.
In order to promote the quality and diversity of result, this example illustratively uses the Wasserstein in WGAN-GP model Distance carrys out regulation loss function.Specifically, above-mentioned shape generates the training objective of confrontation network and loss function may include:
