[0048] Exemplary embodiments of the present application will be described hereinafter with reference to the accompanying drawings. Although exemplary embodiments of the present application are shown in the drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that the present application will be thoroughly and completely understood, and so that the scope of the present application will be completely conveyed to those skilled in the art.

[0049] Figure 1 A flowchart illustrating an embodiment of the present invention provides a user verification method applied to a client-side front-end, which is implemented in a computing device. The computing device includes a processor, a memory, a communication interface, and a communication bus. The processor, the memory, and the communication interface communicate with each other via the communication bus. The memory stores at least one executable instruction, which causes the processor to perform an operation corresponding to the user verification method. Figure 1 As shown, the method includes the following steps:

[0050] Step 110: Detect access to the verification page and send a request to load the verification image;

[0051] Step 120: Receive the verification graphic, and display the verification graphic and the simulated verification area on the verification page;

[0052] Step 130: Detect the simulated graphic input by the user in the simulated verification area, submit the feature point data of the simulated graphic, so that the overlap between the simulated graphic and the verification graphic can be calculated based on the feature point data of the simulated graphic and the feature point data of the verification graphic, and obtain the verification result based on the overlap.

[0053] In this embodiment, when a user opens the verification page on the client, the front end detects the user's access operation to the verification page. When the user's access operation is detected as loading a verification graphic, the front end sends a request to load the verification graphic. The generation of the verification graphic is done on the client's back end. After the client's back end generates the verification graphic, it sends the verification graphic to the front end. After receiving the verification graphic, the front end displays the verification graphic and a simulated verification area on the verification page. The purpose of displaying the simulated verification area is to facilitate the user to draw a simulated graphic in the simulated verification area. When the front end detects that the user has entered a simulated graphic in the simulated verification area, it submits the feature point data of the simulated graphic to the back end, so that the back end can calculate the overlap between the simulated graphic and the verification graphic based on the feature point data of the simulated graphic and the verification graphic, and thus obtain the verification result based on the overlap.

[0054] In one alternative approach, the verification pattern is a random periodic pattern with the number of sampling periods as the first random value, the number of sampling points in any period as the second random value, the sampling interval as the third random value, and / or the generating function as a random function.

[0055] The feature point data of the verification graphic includes the coordinates of the highest and lowest points of the verification graphic in each sampling period, and the feature point data of the simulation graphic includes the coordinates of the highest and lowest points of the simulation graphic in each sampling period.

[0056] In the optional mode, since the user manually draws the simulation figure for verification, considering the uncertainty of manual drawing and the fault tolerance of verification, the embodiment of the application only calculates the coordinate data of the highest point and the lowest point. In actual implementation, other feature points can also be added for verification.

[0057] In an optional mode, the verification figure and the simulation verification area displayed on the verification page are specifically:

[0058] The coordinate axis area is displayed on the verification page, the verification figure is displayed on a part of the coordinate axis area, and the simulation verification area is arranged on another part of the coordinate axis area.

[0059] Figure 2 A schematic diagram of a verification page of an embodiment of the application is shown in FIG. 1. Figure 2 As shown in FIG. 1, the display figure is located in the left region of the coordinate axis area, and the simulation verification area is arranged in the right region of the coordinate axis area. The user can input the simulation figure in the simulation verification area on the right side of the coordinate axis area for verification.

[0060] In the above embodiment, the front end performs verification according to the simulation figure and the verification figure, which has the advantages of novel verification style and simple operation; the verification figure is a random periodic figure with the sampling period number as the first random value, the sampling point number of any period as the second random value, the sampling interval as the third random value, and / or the generation function as the random function, so that the style of the verification figure is various, it is difficult to be cracked in advance by a machine, and the security of verification can be improved.

[0061] Figure 3 A flowchart of a method for user verification of a back end applied to a client is shown in FIG. 2. The method is applied to a computing device. The computing device includes a processor, a memory, a communication interface, and a communication bus, and the processor, the memory, and the communication interface complete communication with each other through the communication bus; the memory is used to store at least one executable instruction, and the executable instruction causes the processor to perform the operation corresponding to the method for user verification. As shown in FIG. 2, the method includes the following steps: Figure 3

[0062] Step 210: receiving a request for loading a verification figure;

[0063] Step 220: generating and returning the verification figure according to the request;

[0064] Step 230: obtaining feature point data of a simulation figure input by a user in a simulation verification area;

[0065] ​Step 240: calculating the overlap degree of the simulation graph and the verification graph according to the feature point data of the simulation graph and the feature point data of the verification graph, and obtaining the verification result according to the overlap degree.

[0066] In this embodiment, when a user opens a verification page on a client, if the front end detects that the user's access operation is an operation of loading a verification graph, the front end sends a request for loading the verification graph. After the back end receives the verification request sent by the front end, the back end generates a verification graph according to the verification request and returns the verification graph to the client front end. After the user draws a simulation graph according to the verification graph on the front end, the back end obtains the feature point data of the simulation graph input by the user, calculates the overlap degree of the simulation graph and the verification graph according to the feature point data of the simulation graph and the feature point data of the verification graph, and obtains the verification result according to the overlap degree.

[0067] In an optional manner, the generating and returning the verification graph according to the request further includes:

[0068] obtaining a random sampling period number, a sampling interval, a sampling point number of any period, and / or a generating function according to the request;

[0069] generating a random periodic graph as the verification graph according to the random sampling period number, the sampling interval, the sampling point number of any period, and / or the generating function;

[0070] After the generating and returning the verification graph according to the request, the method further includes:

[0071] obtaining the highest point coordinate data and the lowest point coordinate data of the verification graph in each sampling period as the feature point data of the verification graph.

[0072] In an optional manner, the calculating the overlap degree of the simulation graph and the verification graph according to the feature point data of the simulation graph and the feature point data of the verification graph, and obtaining the verification result according to the overlap degree further includes:

[0073] calculating the overlap degree of the simulation graph and the verification graph according to the highest point coordinate data and the lowest point coordinate data of the verification graph in each sampling period, the highest point coordinate data and the lowest point coordinate data of the simulation graph in each sampling period, the sampling period number, and the wavelength;

[0074] obtaining the verification result according to the comparison between the overlap degree and a preset overlap degree threshold.

[0075] In the optional mode, the comparison of the overlap degree and the preset overlap degree threshold value obtains a verification result, specifically: if the calculated overlap degree is within the preset overlap degree threshold value range, the verification passes, and if the calculated overlap degree is not within the preset overlap degree threshold value range, the verification fails, and the front end will again issue a request to load the verification pattern for verification again.

[0076] In the above embodiment, the verification is performed according to the overlap degree of the simulation pattern and the verification pattern, which has the advantage of accurate verification; in addition, the overlap degree determination can switch the granularity to improve the verification difficulty and reduce the risk of machine cracking.

[0077] In order to facilitate the understanding of the above-mentioned embodiments of the present application, the following will be described in detail through an embodiment related to a specific application scenario.

[0078] In the process of user browsing the client, when verification is needed, the front end issues a request to load the verification pattern, and after the back end receives the verification request issued by the front end, the verification pattern is generated according to the verification request and returned to the client front end, and the generation process of the verification pattern is as follows:

[0079] The number of sampling periods is set to T_NUM, the number of sampling points in any period is equal and is P_NUM, the range of the sampling sub-interval corresponding to each sampling period can be obtained according to the random sampling interval A and the number of sampling periods T_NUM, and thus the interval set N between adjacent two sampling points in each sampling period can be obtained according to the range of the sampling sub-interval and the number of sampling points in any period.

[0080] The random generation function is set to a sine function, and thus the basic waveform can be generated through Y=sin(2πFN), wherein F is the sampling frequency, and T_NUM times of accumulation of the Y direction coordinate value are performed on the generated basic waveform within the number of sampling periods T_NUM, to obtain a waveform with a period number of T_NUM, which is the verification pattern to be generated.

[0081] After the front end receives the verification pattern, the verification pattern and the simulation verification area are displayed on the verification page, the user draws the simulation pattern in the simulation verification area by taking the verification pattern as a reference after reading the verification pattern on the verification page, and after the front end detects that the user inputs the simulation pattern in the simulation verification area, the feature point data of the simulation pattern is submitted to the back end, and the back end also obtains the feature point data of the verification pattern. Specifically, the feature point data is the highest point coordinate data and the lowest point coordinate data in each sampling period, and the feature point data set of the verification pattern is represented by LOCATION_VALUE, and thus:

[0082]

[0083] Use U_LOCATION_VALUE to represent the feature point data set of the simulation graph, then:

[0084]

[0085] Finally, the backend calculates the overlap of the simulation graph and the verification graph according to the feature point data of the simulation graph and the feature point data of the verification graph, and uses OVERLAP_VAL to represent the overlap of the simulation graph and the verification graph, then the calculation formula of the overlap is:

[0086]

[0087] In the formula, u_x i is the corresponding x coordinate in the feature point data set of the simulation graph, u_y i is the corresponding y coordinate in the feature point data set of the simulation graph, x i is the corresponding x coordinate in the feature point data set of the verification graph, and y i is the corresponding y coordinate in the feature point data set of the verification graph.

[0088] Finally, according to the overlap of the verification graph and the simulation graph, it can be determined whether the overlap is within the preset overlap threshold range to obtain the verification result.

[0089] The user verification method of the embodiment of the application verifies by the overlap of the verification graph and the simulation graph, has the advantages of novel verification style and simple operation; in addition, different verification graphs can be generated according to different functions, so the style of the verification graph is various and difficult to be cracked by a machine; the embodiment of the application can switch the granularity according to the overlap of the verification graph and the simulation graph, improve the verification difficulty, and reduce the risk of machine cracking.

[0090] Figure 4 A structure schematic diagram of a user verification device applied to a front end of a client is shown. Figure 4 As shown in the figure, the device comprises a sending module 310, a display module 320 and a submission module 330, wherein:

[0091] The sending module 310 is used for detecting the access operation of a verification page, and sending a request for loading a verification graph;

[0092] The display module 320 is used for receiving the verification graph, and displaying the verification graph and a simulation verification area on the verification page;

[0093] The submitting module 330 is configured to detect a simulation graph input by a user in the simulation verification area, and submit feature point data of the simulation graph, so as to calculate an overlap degree of the simulation graph and the verification graph according to the feature point data of the simulation graph and the feature point data of the verification graph, and obtain a verification result according to the overlap degree.

[0094] In this embodiment, when a user opens a verification page on a client, a front end detects an access operation of the user on the verification page, and sends a request for loading a verification graph when detecting that the access operation of the user is the operation of loading the verification graph. The verification graph is generated on a back end of the client, and the back end of the client sends the verification graph to the front end after generating the verification graph. The front end displays the verification graph and a simulation verification area on the verification page after receiving the verification graph. The purpose of displaying the simulation verification area is to facilitate the user to draw a simulation graph in the simulation verification area. After the front end detects that the user inputs the simulation graph in the simulation verification area, the front end submits feature point data of the simulation graph to the back end, so that the back end calculates an overlap degree of the simulation graph and the verification graph according to the feature point data of the simulation graph and the feature point data of the verification graph, and obtains a verification result according to the overlap degree.

[0095] In an optional manner, the verification graph received by the displaying module 320 is a random periodic graph with a sampling period number as a first random value, a sampling point number of any period as a second random value, a sampling interval as a third random value, and / or a random function as a generating function.

[0096] The feature point data of the verification graph includes highest point coordinate data and lowest point coordinate data of the verification graph in each sampling period, and the feature point data of the simulation graph submitted by the submitting module 330 includes highest point coordinate data and lowest point coordinate data of the simulation graph in each sampling period.

[0097] In this optional manner, since the user manually draws the simulation graph for verification, considering the uncertainty of manual drawing and the fault tolerance of verification, the embodiment only calculates the coordinate data of the highest point and the lowest point. In actual implementation, other feature points can also be added for verification.

[0098] In an optional manner, the displaying of the verification graph and the simulation verification area on the verification page by the displaying module 320 is specifically as follows.

[0099] The displaying module 320 displays a coordinate axis region on the verification page, the verification graph is displayed on a part of the coordinate axis region by the displaying module 320, and the simulation verification area is set on another part of the coordinate axis region by the displaying module 320.

[0100] In the above embodiment, the front end verifies according to the simulation pattern and the verification pattern, has the advantages of novel verification pattern and simple operation; the verification pattern is a random periodic pattern with a sampling period number as a first random value, a sampling point number of any period as a second random value, a sampling interval as a third random value and / or a generating function as a random function, so the pattern of the verification pattern is various, difficult to be cracked in advance by a machine, and the security of verification can be improved.

[0101] Figure 5 A structure schematic diagram of a device for user verification of a back end applied to a client is shown, as Figure 5 As shown, the device comprises a first receiving module 410, a generating module 420, a second receiving module 430 and a verification module 440, wherein:

[0102] The first receiving module 410 is used for receiving a request for loading a verification pattern.

[0103] The generating module 420 is used for generating and returning a verification pattern according to the request.

[0104] The second receiving module 430 is used for obtaining feature point data of a simulation pattern input by a user in a simulation verification area.

[0105] The verification module 440 is used for calculating an overlap degree of the simulation pattern and the verification pattern according to the feature point data of the simulation pattern and the feature point data of the verification pattern, and obtaining a verification result according to the overlap degree.

[0106] In this embodiment, when a user opens a verification page on a client, the front end detects that the access operation of the user is a loading operation of a verification pattern, the front end sends a request for loading the verification pattern, the back end receives the verification request sent by the front end, generates a verification pattern according to the verification request and returns the verification pattern to the front end of the client, the user draws a simulation pattern according to the verification pattern on the front end, the back end obtains feature point data of the simulation pattern input by the user, calculates an overlap degree of the simulation pattern and the verification pattern according to the feature point data of the simulation pattern and the feature point data of the verification pattern, and obtains a verification result according to the overlap degree.

[0107] In an optional manner, the generating module 420 generating and returning a verification pattern according to the request further comprises:

[0108] The generating module 420 obtains a random sampling period number, a sampling interval, a sampling point number of any period and / or a generating function according to the request.

[0109] The generating module 420 generates a random periodic pattern as the verification pattern according to the random sampling point number of any period, the sampling interval, the sampling period number and / or the generating function.

[0110] After the generation module 420 generates and returns the verification graphic according to the request, the device further includes a third receiving module, which is used to receive the highest point coordinate data and the lowest point coordinate data of the verification graphic in each sampling period, as feature point data of the verification graphic.

[0111] In an optional manner, the verification module 440 calculates the overlap between the simulated graphic and the verification graphic based on the feature point data of the simulated graphic and the feature point data of the verification graphic, and obtains the verification result based on the overlap, further including:

[0112] The verification module 440 calculates the overlap between the simulated graphic and the verification graphic based on the highest and lowest point coordinates of the verification graphic in each sampling period, the highest and lowest point coordinates of the simulated graphic in each sampling period, the number of sampling periods, and the wavelength.

[0113] The verification module 440 obtains the verification result by comparing the overlap with the preset overlap threshold.

[0114] In this optional method, the verification module 440 obtains the verification result by comparing the overlap with the preset overlap threshold. Specifically, if the calculated overlap is within the preset overlap threshold range, the verification module 440 determines that the simulated graphic passes the verification. If the calculated overlap is not within the preset overlap threshold range, the verification module 440 determines that the simulated graphic fails the verification. After the verification fails, the front end will send a request to load the verification graphic again so that the verification can be performed again.

[0115] In the above embodiments, verification is performed based on the overlap between the simulated graphic and the verification graphic, which has the advantage of accurate verification. In addition, the granularity of the overlap determination can be switched, which increases the verification difficulty and reduces the risk of machine cracking.
