Description

[0002] Currently, the verification methods for preventing users from brute-force logging in mainly include the following: One is the verification method with high requirements for login security, which usually uses the method of SMS verification code or picture verification code, combined with server-side verification operations to complete the login verification. The other is the verification method with low requirements for security, which uses verification methods without server participation such as dragging to complete a picture, or directly submitting a form to the server side for verification.

[0032] Here, the exemplary embodiments will be described in detail, and the examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present application. On the contrary, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0033] The block diagrams shown in the drawings are only functional entities and do not necessarily correspond to physically independent entities. That is, these functional entities can be implemented in software form, or implemented in one or more hardware modules or integrated circuits, or implemented in different networks and / or processor devices and / or microcontroller devices.

[0034] The flowcharts shown in the drawings are only illustrative descriptions, and do not necessarily include all contents and operations / steps, nor do they necessarily need to be executed in the described order. For example, some operations / steps can be decomposed, while some operations / steps can be combined or partially combined. Therefore, the actual execution order may change according to the actual situation.

[0035] In this application, "a plurality of" refers to two or more. "And / or" describes the association relationship of associated objects, indicating that there can be three relationships. For example, A and / or B can represent: A exists alone, A and B exist simultaneously, and B exists alone. The character " / " generally represents an "or" relationship between the associated objects before and after.

[0036] Please refer to Figure 1 as shown Figure 1 is a schematic diagram of the normal login process of existing users. After the user accesses the login interface, a form including the input account and password is directly submitted to the server side for verification. Among them, because the verification process requires the participation of the server, the verification pressure on the server is too high. In order to prevent brute-force login by users or cracking of password libraries by password stealing software, to prevent brute-force login by users or cracking of password libraries by password stealing software. Currently, a verification method using SMS verification codes or picture verification codes is adopted to verify the verification request, and its verification process requires the participation of the server, resulting in a relatively large verification pressure on the server. Although the verification method of dragging to complete the picture does not require the participation of the server, due to its single dragging direction, it is easily cracked by password stealing software, and its security is relatively low.

[0037] Therefore, on the one hand, this application provides a verification method for the login interface, which adds a preposed drawing verification method on the basis of normal user login. Specifically, please refer to Figure 2 , Figure 2 is a schematic diagram of the flow of a verification method for a login interface shown in an exemplary embodiment of this application. This verification method at least includes S210 to S240, which are introduced in detail as follows:

[0038] S210: In response to the drawing verification request triggered by the user, display the drawing strategy passing through the drawing verification request on the login interface; wherein, the drawing strategy includes a specified drawing area.

[0039] The drawing verification request can be a verification request triggered by the user for the first time on the login interface, or a verification request triggered after the number of times of other verification methods reaches a preset number. Exemplarily, as Figure 1 shown, the user submits the form to the server for verification multiple times. If the number of server verifications reaches the first preset verification number, the server directly locks the terminal IP and prohibits the terminal from logging in within the locked time. To reduce the verification pressure on the server and reduce the number of server verifications, this application enables the verification method of this embodiment when the number of server verifications reaches the second preset verification number. And in the subsequent verification process, if it is detected that the subsequent number of server verifications reaches the third preset verification number, the server directly locks the terminal IP and prohibits the terminal from logging in within the locked time. Among them, the second preset verification number is less than the first preset verification number, and the sum of the second preset verification number and the third preset verification number is equal to the first preset verification number.

[0040] Specifically, existing users can submit the form to the server for verification a total of 5 times on the normal login interface. If the server still fails the verification for the 5th time, the terminal IP will be directly locked and the terminal will be prohibited from logging in within the locked time. In this embodiment, if it is detected that the server fails the verification for the 3rd time, the execution end of this embodiment responds to the drawing verification request triggered by the user and starts to execute the drawing verification method. It should be noted that in order not to increase the original number of server verifications, the subsequent server will perform at most 2 more verification operations and then lock the terminal IP. For example, after the first drawing verification is successful, the login interface jumps to the normal login interface, and the current form is submitted to the server for verification. If the server verification fails, drawing verification needs to be performed again. After the verification is successful, the form can be submitted to the server for verification again. If the server still fails the verification for the second time, the terminal IP will be directly locked and the terminal will be prohibited from logging in within the locked time. It should be noted that the number of drawing verifications in this embodiment is not limited.

[0041] The user understands the relevant requirements of the drawing process through the drawing strategy displayed on the login interface, especially the specified drawing area. For example, a blank drawing page is displayed on the login interface and divided into multiple drawing areas, such as divided into 4 drawing areas in the upper left, lower left, upper right, and lower right. The specified drawing area can be one or more of them. For example, the drawing strategy requires the user to perform drawing operations in the upper left and lower left drawing areas.

[0042] The drawing strategy also includes the shape of the graph, the drawing order, the number of drawings, etc. This embodiment does not specifically limit them. For example, the drawing strategy requires drawing a circle in the first drawing area and a triangle in the second area; or requires drawing two circles in the first drawing area, so that the trajectory data generated by the user involves multiple trajectory coordinates, increasing the verification data volume, reducing accidental errors, and thus improving the accuracy of the verification process.

[0043] For another example, it is required to draw a circle clockwise in the second drawing area. That is, when recording the trajectory data, the generation time of each trajectory coordinate point is recorded to combine the position coordinates of two adjacent trajectory coordinate points, so as to determine the drawing order during the user's drawing process, increasing the data to be detected in the trajectory data and increasing the cracking difficulty of the password stealing software, thereby improving the security of the verification process.

[0044] S220: Obtain the trajectory data generated by the user during the drawing process on the login interface in response to the drawing strategy; wherein, the trajectory data includes multiple trajectory coordinate points.

[0045] The user draws a graph on the login interface according to the drawing strategy, and multiple trajectory coordinate points are generated during the drawing process.

[0046] Exemplarily, the drawing strategy is to draw a circle in the upper left area of the drawing page. In response to this drawing strategy, the user uses the mouse to draw a circle in the upper left area. Wherein, the drawing page is similar to a two-dimensional coordinate system, and the user generates trajectory data including multiple two-dimensional coordinate points during the drawing process.

[0047] In a preferred embodiment, the trajectory data in this embodiment is continuous data, that is, the trajectory data generated by the user continuously without interruption. If the user breaks or pauses during the drawing process, it will cause the lack of continuity of the trajectory data, and the user needs to draw continuously again to collect continuous trajectory data. Because the continuous trajectory data is obtained by the user's continuous drawing, the continuity between the trajectory coordinate points in the trajectory data is stronger, and thus the shape of the trajectory graph formed by the trajectory coordinate points is more complete, greatly reducing the error of subsequent graph verification.

[0048] S230: Detect whether all trajectory coordinate points are within the specified drawing area.

[0049] Obtain the range value of the first coordinate axis corresponding to the specified drawing area and the range value of the corresponding second coordinate axis. If the first coordinate axis value of each trajectory coordinate point is within the range value of the first coordinate axis corresponding to the specified drawing area, and the second coordinate axis value of each trajectory coordinate point is within the range value of the second coordinate axis corresponding to the specified drawing area, it is determined that all trajectory coordinate points are within the specified drawing area, otherwise they are not.

[0050] S240: If so, perform a verification operation on the trajectory data according to the specified preset graph verification strategy, and determine whether to pass the drawing verification request according to the verification result.

[0051] Exemplarily, if it is detected that all the trajectory coordinate points are within the specified drawing area, then the next step of detailed verification is performed. For example, the shape of the figure generated by the user in the specified drawing area is determined according to the trajectory data, and it is detected whether the shape of the figure is the shape of the figure in the specified preset figure verification strategy. If so, the drawing verification request is passed; if not, the drawing verification request is not passed.

[0052] In this embodiment, it is required that all the trajectory coordinate points are within the specified drawing area, and then the trajectory data is verified according to the specified preset figure verification strategy, forming a progressive verification process. It should be noted that there is a corresponding relationship between the preset figure verification strategy and the drawing strategy. For example, if the drawing strategy is to draw a circle, the specified preset figure verification strategy is the preset circle verification strategy.

[0053] In some other embodiments, if it is detected that all the trajectory coordinate points are not within the specified drawing area, it is directly indicated that the drawing verification request is not passed. The drawing page of the login interface can be cleared, and the new drawing strategy is displayed on the login interface; or it is displayed on the login interface that the drawing verification request is not passed, so that the user can decide whether to trigger the drawing verification request again. If it is detected that the user triggers the drawing verification request again, the drawing page of the login interface is cleared, and the new drawing strategy is displayed on the login interface.

[0054] In the embodiment of the present application, by responding to the drawing verification request triggered by the user, the drawing strategy that passes the drawing verification request is displayed on the login interface; the human-computer interaction intensity in the verification process is enhanced, and the trajectory data generated by the user during the drawing process on the login interface is obtained for verification. Because the trajectory data is dynamic data generated during the interaction between the user and the login interface, the difficulty of forging data is increased, and the security of the verification process is improved to a certain extent. Secondly, it is required that all the trajectory coordinate points are within the specified drawing area, and then the trajectory data is verified according to the specified preset figure verification strategy, that is, a progressive verification process is formed, enhancing the security of the verification process. In addition, the verification method of the present application only performs verification operations on the login interface without server operation processing, thereby reducing the verification pressure on the server.

[0055] In an exemplary embodiment of the present application, it is illustrated how to verify the trajectory data according to the specified preset figure verification strategy, and how to determine whether to pass the drawing verification request according to the verification result. For details, please refer to Figure 3 , Figure 3 is based on Figure 2 shown in the flow chart of another verification method for the login interface shown in the exemplary embodiment. This verification method further includes S310 to S320 in S240 as shown in Figure 2 shown, and the details are introduced as follows:

[0056] S310: Determine the trajectory graph obtained by the user's drawing in the specified drawing area based on multiple trajectory coordinate points.

[0057] S320: Match the trajectory graph with the preset graph in the specified preset graph verification strategy, and use the obtained matching result as the verification result to determine whether the drawing verification request is passed.

[0058] An exemplary description of this embodiment is as follows: The preset graph in the specified preset graph verification strategy is a rectangle. Restore the trajectory graph obtained by the user's drawing in the specified drawing area based on multiple trajectory coordinate points, and match the shape of the trajectory graph with the shape of the preset graph. If the match is successful, it indicates that the shape of the trajectory graph is also a rectangle, and the drawing verification request is passed. If the match fails, it indicates that the shape of the trajectory graph is not a rectangle, and the drawing verification request is not passed.

[0059] This embodiment provides a method for verifying trajectory data according to a specified preset graph verification strategy. Accurately restore the trajectory graph obtained by the user's drawing in the specified drawing area based on multiple trajectory coordinate points, and match it with the preset graph in the specified preset graph verification strategy to accurately determine whether the drawing verification request is passed.

[0060] In an exemplary embodiment of the present application, the above S240 is described in detail. Among them, the preset graph verification strategy includes a triangle verification strategy. For details, please refer to Figure 4 , Figure 4 which is based on Figure 2 shown in the flow diagram of another verification method for the login interface in the exemplary embodiment. This verification method further includes S410 to S430 in S240 as shown in Figure 2 and is introduced in detail as follows:

[0061] S410: Determine four target coordinate point arrays based on multiple trajectory coordinate points, and divide the multiple trajectory coordinate points into the four target coordinate point arrays.

[0062] Exemplarily, traverse each trajectory coordinate point, determine an array of target coordinate points with the largest value on the first coordinate axis, and divide the trajectory coordinate points corresponding to the largest value on the first coordinate axis into this array of target coordinate points; determine an array of target coordinate points with the smallest value on the first coordinate axis, and divide the trajectory coordinate points corresponding to the smallest value on the first coordinate axis into this array of target coordinate points; determine an array of target coordinate points with the largest value on the second coordinate axis, and divide the trajectory coordinate points corresponding to the largest value on the second coordinate axis into this array of target coordinate points; determine an array of target coordinate points with the smallest value on the second coordinate axis, and divide the trajectory coordinate points corresponding to the smallest value on the second coordinate axis into this array of target coordinate points. Divide in the above manner, and the same trajectory coordinate point may be repeatedly divided into different arrays of target coordinate points.

[0063] S420: Determine a preset determination strategy for the vertices of the trajectory graph according to the number of trajectory coordinate points in each array of target coordinate points, so as to obtain the trajectory graph.

[0064] Please refer to Figure 5 , Figure 5 which is a schematic diagram showing three distribution cases of the vertices of a triangle shown in an exemplary embodiment of the present application. This embodiment provides three preset determination strategies for determining the vertices of the trajectory graph:

[0065] Exemplarily, there is only one trajectory coordinate point in each target coordinate array: respectively obtain the only one trajectory coordinate point from the four arrays of target coordinate points; respectively calculate the distances between two different trajectory coordinate points, so as to determine the two trajectory coordinate points with the shortest distance; take the average values X 1 and Y 1 of the X-axis and Y-axis of these two trajectory coordinate points, X 1 and Y 1 constitute a new point coordinate, which is used as a vertex of the trajectory graph; the remaining two trajectory coordinate points are used as the other two vertices of the trajectory graph. As shown in ① of Figure 5 , the trajectory coordinate point (X 最小 , Y 最大 ) is located in the array of target coordinate points with the smallest value on the X-axis and also in the array of target coordinate points with the largest value on the Y-axis, that is, the distance between the trajectory coordinate points in these two arrays of target coordinate points is 0, that is, (X 最小 , Y 最大 ) is a vertex of this trajectory graph, and the trajectory coordinates in the other two arrays of target coordinate points are the other two vertices.

[0066] Another exemplarily, among the four arrays of target coordinate points, there is an array of target coordinate points with multiple trajectory coordinate points. Traverse the array of target coordinate points with multiple trajectory coordinate points. If the values of the X-axis corresponding to all trajectory coordinate points are the same, then the vertices of the trajectory graph are located in the array of target coordinate points with the smallest value on the Y-axis, or asFigure 5 As shown in ②: the vertex is located in the target coordinate point array with the largest Y-axis value; if the Y-axis values corresponding to all the trajectory coordinate points are the same, the vertex of the trajectory graph is located in the target coordinate point array with the smallest X-axis value, or in the target coordinate point array with the largest X-axis value.

[0067] Furthermore, if there is only one trajectory coordinate point in the target coordinate point array to which the vertex belongs, it is directly used as a vertex of the trajectory graph.

[0068] If there are multiple trajectory coordinate points in the target coordinate point array to which the vertex belongs, and the X-axis values corresponding to all the trajectory coordinate points are the same, then the trajectory coordinate point with the largest Y-axis value and the trajectory coordinate point with the smallest Y-axis value in this target coordinate point array are used as two vertices of the trajectory graph.

[0069] If there are multiple trajectory coordinate points in the target coordinate point array to which the vertex belongs, and the Y-axis values corresponding to all the trajectory coordinate points are the same, then the trajectory coordinate point with the largest X-axis value and the trajectory coordinate point with the smallest X-axis value in this target coordinate point array are used as two vertices of the trajectory graph.

[0070] Another example is that among the four target coordinate point arrays, two target coordinate points each have only one trajectory coordinate point, and the remaining two target coordinate point arrays each have multiple trajectory coordinate points, as Figure 5 shown in ③,

[0071] Traverse the two target coordinate point arrays with multiple trajectory coordinate points respectively. If the X-axis values corresponding to all the trajectory coordinate points in the currently traversed target coordinate point array are the same, then the trajectory coordinate point with the largest Y-axis value and the trajectory coordinate point with the smallest Y-axis value in the current target coordinate point array are used as the first plotted point and the second plotted point.

[0072] If the Y-axis values corresponding to all the trajectory coordinate points in the currently traversed target coordinate point array are the same, then the trajectory coordinate point with the largest X-axis value and the trajectory coordinate point with the smallest X-axis value in the current target coordinate point array are used as the third plotted point and the fourth plotted point.

[0073] Among the above four plotted points, calculate the distance between each two plotted points, and determine a vertex of the trajectory graph according to the two plotted points with the shortest distance. For example, take the average value of the corresponding X-axis and the average value of the corresponding Y-axis of the two plotted points with the shortest distance as the X-axis value and the Y-axis value corresponding to this vertex. And use the other two target coordinate points each with only one trajectory coordinate point as the other two vertices of the trajectory graph.

[0074] S430: Verify whether the trajectory graph is a triangle, and determine whether to pass the drawing verification request based on the verification result.

[0075] For the three vertices determined according to the above steps, connect two vertices in sequence to determine whether the formed trajectory graph is a triangle. If so, the drawing verification requirement is passed; if not, the drawing verification requirement is not passed.

[0076] This embodiment provides a method for verifying trajectory data according to a triangle verification strategy. Three vertices of the trajectory graph are determined through trajectory coordinate points, and a complete trajectory graph is constructed based on the three vertices to determine whether it is a triangle. This embodiment conducts verification through the verification strategy of a simple graph, which is convenient for users to draw; and during the verification process, due to the simplicity of the graph, the difficulty of the verification process is reduced while ensuring verification security.

[0077] Further, in an exemplary embodiment of the present application, S430 is described in detail. For specific details, please refer to Figure 6 , Figure 6 is based on Figure 4 shown in the flow diagram of another verification method for the login interface in the exemplary embodiment. This verification method further includes S610 to S630 in S430 as shown in Figure 4 shown below:

[0078] S610: Select sample trajectory coordinate points from multiple trajectory coordinate points and record the total number of sample trajectory coordinate points.

[0079] The sample selection method can be random selection or sequential extraction of samples at a preset sampling interval. The number of samples obtained each time is different, so the total number of samples needs to be recorded.

[0080] S620: Determine three side lines of the trajectory graph according to the vertices of the trajectory graph, calculate the distance value from each sample trajectory coordinate point to the corresponding side line, and calculate the error value between each distance value and the preset distance value.

[0081] Exemplarily, a target straight line can be determined according to two target coordinate points (i.e., the vertices of the trajectory graph). For example, according to the coordinate values of the two target coordinate points, the straight line equation of the target straight line is determined, so as to determine the straight line equations of the three target straight lines.

[0082] Calculate the distance value from each sample trajectory coordinate point to the adjacent side line. For example, if the A sample trajectory coordinate point is adjacent to the first target straight line, calculate the distance from the A sample trajectory coordinate point to the first target straight line; if it is calculated that the B sample trajectory coordinate point is adjacent to the third target straight line, calculate the distance from the B sample trajectory coordinate point to the third target straight line.

[0083] Among them, the determination method of the sample trajectory coordinate points corresponding to the adjacent side lines is as follows Figure 7 shown Figure 7 is a schematic diagram of the determination method of the adjacent side line of the trajectory coordinate point shown in an exemplary embodiment of the present application. According to the two vertex coordinates of the target punctuation: A and B, the adjacent range adjacent to the target side line is determined, that is Figure 7 the dashed rectangle in, and the adjacent side line of the trajectory coordinate point in the dashed rectangle is the target side line

[0084] Both the preset distance value and the following preset error value are preset parameters. An exemplary calculation formula for the error value is as follows

[0085] K = |distance value - preset distance value|;

[0086] Among them, K represents the error value, and the specific unit is not limited in this embodiment

[0087] S630: Calculate the error percentage according to the number of sample trajectory coordinate points with an error value greater than the preset error value and the total number of sample trajectory coordinate points, and verify whether the trajectory graph is a triangle according to the error percentage

[0088] Exemplarily, the error percentage is calculated according to the following formula

[0089] Error percentage = N / M;

[0090] Among them, N represents the number of sample trajectory coordinate points with an error value greater than the preset error value, and M represents the total number of sample trajectory coordinate points

[0091] If the calculated error percentage is greater than the preset error percentage, it indicates that the trajectory graph is not a triangle; if the calculated error percentage is less than the preset error percentage, it indicates that the trajectory graph is a triangle; if the calculated error percentage is equal to the preset error percentage, it can indicate that the trajectory graph is not a triangle, or it can also indicate that the trajectory graph is a triangle, and this embodiment does not limit it

[0092] This embodiment further illustrates how to determine whether the shape of the trajectory graph is a triangle. By means of sampling calculation, it is not necessary to calculate and process all data, reducing the amount of data calculation, thereby improving the verification efficiency. By numerically processing the distance between points and lines, it is convenient to determine the error value between each distance value and the preset distance value

[0093] In an exemplary embodiment of the present application, S240 is described in detail above. Among them, the preset graph verification strategy includes a circular verification strategy. For details, please refer to Figure 8 , Figure 8 is based on Figure 2Schematic flowchart of another verification method for the login interface shown in the exemplary embodiment. This verification method further includes S810 to S830 in S240 as shown in Figure 2 and is described in detail as follows:

[0094] S810: Select sample trajectory coordinate points from multiple trajectory coordinate points and record the total number of sample trajectory coordinate points.

[0095] Similar to the above S610, it will not be elaborated here.

[0096] S820: Determine the target center and target radius corresponding to the trajectory graph according to the sample trajectory coordinate points, calculate the distance value from each sample trajectory coordinate point to the target center, and calculate the error value between each distance value and the target radius.

[0097] Exemplarily, arbitrarily select three trajectory coordinate points from the sample trajectory coordinate points to determine a circle, thereby determining its center and radius; and so on, determine multiple circles, thereby determining multiple centers and multiple radii; and take the calculated average center as the target center and the calculated average radius as the target radius.

[0098] An exemplary calculation formula for the error value is as follows:

[0099] K = |distance value - target radius|;

[0100] where K represents the error value, and the specific unit is not limited in this embodiment.

[0101] S830: Calculate the error percentage according to the number of sample trajectory coordinate points with error values greater than the preset error value and the total number of sample trajectory coordinate points, and verify whether the trajectory graph is a circle according to the error percentage.

[0102] Similar to the above S630, it will not be elaborated here.

[0103] Exemplarily, the preset error value is 10; the preset error percentage is 30%, the number of sample trajectory coordinate points with error values greater than 10 is calculated as 50, and the total number of sample trajectory coordinate points is 100, then the error percentage is 50%. Since 50% > 30%, it can be determined that the trajectory graph is not a circle.

[0104] This embodiment further illustrates how to determine whether the shape of the trajectory graph is a circle. By means of sampling calculation, it is not necessary to calculate and process all data, reducing the amount of data calculation and thus improving the verification efficiency. Based on the principle of determining a circle with three trajectory coordinate points, the target center and target radius are determined according to the centers and radii of multiple circles, and the distances from the sample trajectory coordinate points to the target center are determined to calculate the error values between each distance value and the target radius, and then the error percentage is calculated to accurately determine whether the trajectory graph is a circle.

[0105] In an exemplary embodiment of the present application, S240 is described in detail, where the preset graph verification strategy includes a circle verification strategy. For details, please refer to Figure 9 , Figure 9 is based on Figure 2 shown in the flowchart of another verification method for the login interface in the exemplary embodiment. This verification method further includes S910 to S940 in S240 as shown in Figure 2 shown below in detail:

[0106] S910: Determine the four vertices of the trajectory graph from multiple trajectory coordinate points, and determine the four side lines of the trajectory graph according to the four vertices.

[0107] Exemplarily, traverse multiple trajectory coordinate points to determine four vertices (X 最小 , Y 最小 )(X 最小 , Y 最大 )(X 最大 , Y 最小 )(X 最大 , Y 最大 ). Using these four vertices as dividing points, connect them to obtain four side lines, and divide multiple trajectory coordinate points into arrays of trajectory coordinate points adjacent to the side lines respectively.

[0108] S920: Select sample trajectory coordinate points from multiple trajectory coordinate points and record the total number of sample trajectory coordinate points.

[0109] Obtain M trajectory coordinate points from the array of trajectory coordinate points in S910 according to the preset sampling interval.

[0110] S930: Calculate the distance values from each sample trajectory coordinate point to the adjacent side line, and calculate the error values between each distance value and the preset distance value.

[0111] Exemplarily, according to the function expression for determining a side line from two points: (y - y 2 ) / (y 1 - y 2 ) = (x - x 2 ) / (x1 -x 2 ), select two vertices from the four vertices to determine the linear equations Ax + By + C = 0 of the four side lines; calculate the distance from each trajectory coordinate point in the sample trajectory coordinate points to the adjacent side line according to the following formula:

[0112]

[0113] where d represents the distance from the trajectory coordinate point to the adjacent side line; x represents the value of the first coordinate axis corresponding to the trajectory coordinate point; y represents the value of the second coordinate axis corresponding to the trajectory coordinate point; A, B, and C are constants.

[0114] Perform the following formula calculation on the calculated distance value and the preset distance value to obtain the error value:

[0115] K = |distance value - preset distance value|;

[0116] where K represents the error value, and the specific unit is not limited in this embodiment.

[0117] S940: Calculate the error percentage based on the number of sample trajectory coordinate points with error values greater than the preset error value and the total number of sample trajectory coordinate points, and verify whether the trajectory graph is a rectangle according to the error percentage.

[0118] Similar to S630 above, it will not be elaborated here.

[0119] Exemplarily, the preset error value is 8; the preset error percentage is 30%. The number of sample trajectory coordinate points with error values greater than 8 is calculated to be 20, and the total number of sample trajectory coordinate points is 100. Then the error percentage is 20%. Since 20% < 30%, it can be determined that the trajectory graph is a rectangle.

[0120] This embodiment further illustrates how to determine whether the shape of the trajectory graph is a rectangle. By means of sampling calculation, it is not necessary to perform calculation processing on all data, reducing the amount of data calculation, thereby improving the verification efficiency. Based on the principle of determining a straight line by two points, the linear equations of the four side lines of the trajectory graph are calculated, and the distance between the point and the line is numerically processed to facilitate determining the error value between each distance value and the preset distance value, and then calculating the error percentage to accurately determine whether the trajectory graph is a rectangle.

[0121] In an exemplary embodiment of the present application, S240 is described in detail. For details, please refer to Figure 10 , Figure 10 is based on Figures 2 to 4 , Figure 6 , Figures 8 to 9A schematic flowchart of another verification method for a login interface shown in any of the exemplary embodiments. This verification method further includes S1010 to S1020 in S240, which are introduced in detail as follows:

[0122] S1010: If the verification result indicates that the graphic verification fails, it is determined that the drawing verification request is not passed, and the result that the drawing verification request is not passed is displayed on the login interface so that the user can determine whether to trigger the drawing verification request again.

[0123] Exemplarily, if the drawing verification request is not passed, "Drawing verification failed. Do you want to re-perform the drawing verification operation?" is displayed on the login interface. After the user triggers the request to re-perform the drawing verification operation, a new drawing strategy is displayed on the login interface.

[0124] In some embodiments, if the drawing verification request is not passed, "Drawing verification failed" is displayed on the login interface, and a new drawing strategy is displayed on the login interface, that is, without the user triggering the drawing verification request again, the new drawing strategy is directly displayed on the login interface, thereby accelerating the subsequent drawing verification process.

[0125] S1020: If the verification result indicates that the graphic verification is successful, it is determined that the drawing verification request is passed, and the user login information carried by the drawing verification request is sent to the server so that the server can perform a verification operation on the user login information.

[0126] In this embodiment, the drawing verification operation is executed at the login interface end without the participation of the server. Only after the drawing verification request is passed, the user login information will be sent to the server for verification operation. If the server verification is passed, the user logs in successfully and the login interface jumps to the subsequent interface; if the server verification fails, the result of verification failure is returned to the login interface, and the user needs to pass the drawing verification again before the modified or unmodified user login information can be sent to the server.

[0127] This embodiment further illustrates the subsequent operations after the drawing verification request is passed or not. Only after the drawing verification request is passed, the server will receive the user login information sent from the login interface end for verification operation. Compared with the existing operation of the server directly verifying the user login information multiple times, this embodiment reduces the verification times of the server and alleviates the verification pressure of the server.

[0128] To better illustrate how the verification method of the present application alleviates the verification pressure of the server, in another exemplary embodiment of the present application, the application scenarios of the above multiple verification methods are exemplarily illustrated. For details, please refer to Figure 11 , Figure 11It is a schematic diagram of the application scenario of the verification method of this application. Among them, it includes a user terminal 100, a login interface 200, and a server 300. The three terminals can be connected by wireless communication. This application does not limit the connection method between them.

[0129] The user terminal 100 is used to collect information input by the user, including but not limited to user login information and trajectory data generated during the drawing process, etc. The user terminal 100 can send the collected user login information to the login interface 200, and the login interface 200 then sends the user login information to the server 300 so that the server 300 can verify the user login information. Among them, the user terminal 100 includes but not limited to mobile phones, computers, or other PC terminals. This application does not limit its specific device type.

[0130] The login interface 200 can execute any of the above verification methods. Exemplarily, in response to a drawing verification request triggered by the user, the login interface 200 displays the drawing strategy that passes the drawing verification request on the login interface 200; among them, the drawing strategy includes specifying a drawing area; obtaining the trajectory data generated by the user during the drawing process on the login interface 200 in response to the drawing strategy; among them, the trajectory data includes multiple trajectory coordinate points; detecting whether all trajectory coordinate points are within the specified drawing area; if so, perform a verification operation on the trajectory data according to the specified preset graphic verification strategy, and determine whether the drawing verification request is passed according to the verification result.

[0131] In a preferred embodiment, the login interface 200 sends the user login information input by the user through the user terminal 100 to the server 300 for verification. If the number of verification failures reaches the preset number of failure times, the login interface 200 will display the drawing strategy that passes the drawing verification request on the login interface 200 so that the user can draw according to this drawing strategy, and send the collected trajectory data to the login interface 200 through the user terminal 100. The login interface 200 verifies according to the received trajectory data. If the verification passes, the user login information will be sent to the server 300 for verification. If the server 300 fails to verify the user login information, the login interface 200 will display a new drawing strategy different from the previous one that passed the drawing verification request on the login interface 200 so that the user can draw according to the new drawing strategy. The user terminal 100 sends the newly collected trajectory data to the login interface 200 for re-verification, and so on. If the number of failures in the re-verification reaches the corresponding preset number of failure times, the IP of the user terminal 100 will be locked. In addition, if the number of verification failures of the server 300 reaches the corresponding preset number of verification failures, the IP of the user terminal 100 will also be locked to prevent brute-force login.

[0132] The server 300 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers. Among them, multiple servers can form a blockchain, and the server is a node on the blockchain. The server 300 can also be a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, CDN (Content Delivery Network), and big data and artificial intelligence platforms.

[0161] The verification device on the login interface of the present application displays the drawing strategy that passes the drawing verification request on the login interface by responding to the drawing verification request triggered by the user; enhances the intensity of human-computer interaction during the verification process, and verifies by obtaining the trajectory data generated during the user's drawing process on the login interface.

Secondly, it is required that all trajectory coordinate points are within the specified drawing area before verifying the trajectory data according to the specified preset graph verification strategy, that is, a progressive verification process is formed, enhancing the security of the verification process.
