[0040] Exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0041] Figure 1 FIG. 1 shows a flow chart of a verification method for a verification code applied to a server according to an embodiment of the present invention. Figure 1 As shown, the method includes the following steps:

[0042] Step 11, obtain the verification code image;

[0043] Step 12: segmenting the verification code image to obtain at least two original verification code blocks arranged in a first order;

[0044] Step 13, rearranging the at least two original verification code blocks arranged in the first order to obtain verification code blocks to be verified arranged in a second order;

[0045] Step 14: Send the verification code block to be verified and the prompt rule information to the client;

[0046] Step 15: receiving a target verification code block submitted by the client according to the verification code block to be verified and the prompt rule information;

[0047] Step 16: Verify the position and / or included image blocks of the target verification code block and the original verification code block, obtain a verification result, and send the verification result to the client.

[0048] In this embodiment, the acquired verification code image is segmented to obtain at least two original verification code blocks arranged in a first order, and the at least two original verification code blocks arranged in the first order are rearranged to obtain a verification code block to be verified arranged in a second order; the verification code block to be verified and prompt rule information are sent to the client, and the prompt rule information is used to guide the user of the client to adjust the position and / or rotate the angle of the verification code block to be verified to obtain a target verification code block. The user of the client adjusts the position and / or rotates the angle of the verification code block to be verified according to the prompt rule information to obtain the target verification code block. The server receives the target verification code block submitted by the client, verifies the position and / or the image block included in the target verification code block, and sends the verification result to the client. This effectively increases the difficulty of cracking the verification code to prevent the verification code from being cracked by a machine.

[0049] It should be noted that the first order of the at least two original verification code blocks is preferably the logical order of the at least two original verification codes obtained after the verification code image is segmented; and the at least two original verification code blocks arranged in the first order are rearranged to obtain verification code blocks to be verified arranged in a second order, where the second order preferably includes an order obtained by adjusting the positions and / or rotating the at least two original verification codes; if the verification code image is rectangular, the verification code block is preferably at least two rectangular images obtained by vertically segmenting the rectangular verification code image, and each rectangular image is a cylindrical verification code block formed by butting two opposite wide sides or long sides together, but the present application is not limited to this, and the verification code block may also be a three-dimensional shape such as a cuboid, a cube, or a triangular pyramid;

[0050] Figure 2 FIG. 1 shows a flow chart of obtaining a verification code block to be verified in a specific embodiment of the present invention. Figure 2 As shown in a specific embodiment, the server obtains a verification code image with vertices O, W, M, and H, wherein the origin of the coordinate axis is point O, the coordinates of point O are O(0, 0), the positive direction of the X axis is from left to right, the positive direction of the Y axis is from top to bottom, the line segments OW and HM are the lengths of the verification code image, and l OW =w,l HM =w, line segments OH and WM are the width of the verification code image, l OH =h,l WM =h;

[0051] Connect the long sides of the verification code image, that is, connect the line segment OW and the line segment HM to form a cylindrical verification code block. The total area of ​​the verification code block image block S1 = w * h is the surface area S2 of the cylindrical verification code block; with four lines x parallel to the positive direction of the Y axis 11x 12 、x 21 x 22 、x 31 x 32 and x 41 x 42 Segment the verification code image to form five segmented verification code blocks. Rearrange the segmented verification code blocks to obtain the verification code block to be verified, and send it to the client for verification.

[0052] Specifically:

[0053] Step 1: The segmented verification code blocks include X0, X1, X2, X3 and X4 in sequence;

[0054] Step 2: Adjust the position of the segmented verification code blocks. The adjusted verification code blocks include X3, X1, X2, X0, and X4 in sequence.

[0055] Step 3, perform angle rotation adjustment on the position-adjusted verification code block. The position-adjusted verification code block includes X3, X1, X2, X0 and X4 in sequence. The verification code block after angle rotation adjustment is marked with a dotted line. The verification code block after angle rotation adjustment includes X3', X1', X2', X0' and X4.

[0056] In an optional embodiment of the present invention, step 13 includes:

[0057] Step 131 : performing position adjustment and / or angle rotation adjustment on at least one of the at least two original verification code blocks arranged in the first order to obtain a verification code block to be verified arranged in the second order.

[0058] In this embodiment, the rearrangement of the at least two original verification code blocks arranged in the first order includes position adjustment and / or angle rotation adjustment of the at least two original verification code blocks arranged in the first order.

[0059] Optionally, step 131 includes:

[0060] Step 1311: Using a first random function, for the at least two original verification code blocks arranged in the first order, generate a swap list in which at least one original verification code block is position-adjusted.

[0061] Step 1312: Using a second random function, for the at least two original verification code blocks arranged in the first order, generate a rotation list in which at least one original verification code block is subjected to angle rotation adjustment.

[0062] Step 1313: Perform position adjustment and angle rotation adjustment on at least one of the at least two original verification code blocks according to the interchange list and the rotation list to generate a verification code block to be verified.

[0063] In this embodiment, according to the first random function, an exchange list is generated after the position of at least one original verification code block is adjusted. The number of random exchange positions generated in the exchange list is (qp), that is, at least q exchanges and at most p exchanges. Then, the original verification code blocks to be exchanged are randomly selected. The number of original verification code blocks is N, and the labels of the original verification code blocks are [0, N-1]. An original verification code block is randomly selected from the label range of the original verification code blocks [0, m-1] and [m+1, N-1] and is recorded as the original verification code block n. Then, an element "mn" in the exchange list is generated, where "mn" represents an exchange record of the original verification code block, m is the label of the original verification code block m, and n is the number of the original verification code block n. Label; It should be noted that the randomly generated element "mn" is an element that does not exist in the current interchange list, that is, the current interchange list preferably does not contain the same element information; according to the second random function, a rotation list is generated after at least one original verification code block is angle-rotated, and the elements in the rotation list are random numbers generated by the second random function between [-180°, 180°], a positive value of the random number indicates clockwise rotation, and a negative value indicates counterclockwise rotation. Of course, a positive value of the random number may also indicate counterclockwise rotation, and a negative value indicates clockwise rotation; the elements in the rotation list preferably correspond to the number of original verification code blocks, that is, each original verification code block corresponds to an element in the rotation list, and when the original verification code block does not undergo angle rotation adjustment, its angle rotation adjustment is 0°;

[0064] In an optional embodiment of the present invention, after step 12, the following steps are further included:

[0065] A cutting point list is generated based on the at least two original verification code blocks arranged in the first order; the elements in the cutting point list are the offsets corresponding to each original verification block, and the offsets are the offsets obtained by multiplying the average length of the original verification code blocks by the offset coefficient obtained by a third random function within a preset offset coefficient range.

[0066] In this embodiment, it should be noted that, based on at least two original verification code blocks arranged in the first order obtained after the segmentation process, a cutting point list is generated. The elements in the cutting point list are the offsets corresponding to each original verification code block. The average length of the original verification code blocks in the verification code image is l ave The offset is the offset coefficient obtained by the third random function within a preset offset coefficient range and the average length is lave The offset obtained by multiplication can be used to split the verification code image into several original verification code blocks, and the length of each original verification code block is within the offset corresponding to the preset offset coefficient range;

[0067] According to the swap list generated by the first random function, at least one original verification code block among the at least two original sub-verification code blocks is positionally adjusted, and then according to the rotation list generated by the second random function, at least one original verification code block among the at least two original verification code blocks after the position adjustment is rotationally adjusted to generate a verification code block to be verified; this effectively increases the difficulty for the client to crack the verification code.

[0068] Optionally, step 1314 includes:

[0069] Step 13141: traverse the at least two original verification code blocks according to the rotation list, adjust the position of at least one original verification code block among the at least two original sub-verification code blocks, and obtain at least two original verification code blocks after position adjustment; traverse the at least two original verification code blocks after position adjustment according to the rotation list, and obtain at least one original verification code block to be rotated and adjusted.

[0070] Step 13142, determining whether at least one original verification code block has been position adjusted;

[0071] Step 13143: If at least one original verification code block has not been position-adjusted, then angle-rotate the at least one original verification code block to obtain a verification code block to be verified.

[0072] Step 13144: If at least one original verification code block has been position-adjusted, perform angle rotation adjustment on the at least one original verification code block, and perform angle rotation adjustment in the opposite direction on the position-adjusted original verification code block corresponding to the at least one original verification code block to obtain a verification code block to be verified.

[0073] In this embodiment, according to the rotation list generated by the second random function, traverse the at least two original verification code blocks to obtain at least one original verification code block to be adjusted by angle rotation, and determine whether the at least one original verification code block to be adjusted by angle rotation has been adjusted in position, that is, whether the label of the at least one original verification code block to be adjusted by angle rotation is the label m in the element "m-n" of the above swap list; if the at least one original verification code block to be adjusted by angle rotation has been adjusted in position, then first adjust the angle rotation of the original verification code block with label m, and then adjust the angle rotation of the original verification code block with label n in the opposite direction; if the at least one original verification code block to be adjusted by angle rotation has not been adjusted in position, then only the original verification code block with label m needs to be adjusted by angle rotation; judge and adjust the angle rotation for each original verification code block to be adjusted by angle rotation to obtain the verification code block to be verified; on the basis of position adjustment, further perform angle rotation adjustment, which increases the cracking difficulty of the verification code and can prevent the verification code from being machine-learned and cracked;

[0074] It should be noted that the element "m-n" in the swap list is different from the element "n-m". The element "m-n" in the swap list means that the original verification code block with label m and the original verification code block with label n have been swapped in position, and it also means that when the original verification code block with label m is adjusted by angle rotation, the original verification code block with label n is adjusted by angle rotation in the opposite direction at the same time; if the element in the swap list is "n-m", it means that the original verification code block with label n and the original verification code block with label m have been swapped in position, and it also means that when the original verification code block with label n is adjusted by angle rotation, the original verification code block with label m is adjusted by angle rotation in the opposite direction at the same time.

[0075] In a specific embodiment, the server obtains a verification code picture composed of points O, W, M, and H. Among them, the length of the verification code picture is h, the width is w, and the resolution is 720p, that is, the size of the verification code picture is 1280*720, then h = 720, w = 1280. Let the number of divided verification code blocks be N, and generate a cutting point list XList; generate a rotation list for the N verification code blocks according to the first random function, and the value range of the elements in the rotation list is [-180°, 180°], and the rotation list is denoted as RotAngList; generate a swap list according to the second random function, and the swap list is denoted as TransList, and the format of the elements in the swap list is "m-n", where m and n are the subscripts of the verification code blocks. Since the upper limit of the number of verification code blocks is N, the value range of m is 0 <= m < N, and the value range of n is 0 <= n < N;

[0076] Specifically, generating the cutting point list XList includes:

[0077] 1.1 Calculate the average length of the verification code blocks after segmentation: BaseEleW = w / N, where BaseEleW is the average length of the verification code blocks, w is the width of the verification code image, and N is the number of verification code blocks after segmentation;

[0078] 1.2 According to the preset offset coefficient range, obtain the offset offset = BaseEleW * (-0.3 to 0.3), where offset is the offset of the verification code block, BaseEleW is the average length of the verification code block, and (-0.3 to 0.3) is the preset offset coefficient range;

[0079] 1.3 Based on the average length and offset of the verification code block, obtain the element value in the cutting point list XList, XList[i+1] = (i+1)*BaseEleW+offset[i], where XList[i+1] is the x-axis coordinate of the cutting point of the i-th verification code block in XList, BaseEleW is the average length of the verification code block, and offset[i] is the offset of the i-th verification code block;

[0080] Generating the rotation list RotAngList includes:

[0081] 2.1 Generate a random number corresponding to the verification code block in the range of [-180°, 180°] according to a second random function. A positive value of the random number represents a clockwise rotation, and a negative value represents a counterclockwise rotation. The elements in the rotation list RotAngList correspond one-to-one to the verification code block.

[0082] Generating the swap list TransList includes:

[0083] 3.1 The number of random swaps is (1-3), i.e. at least 1 swap and at most 3 swaps;

[0084] 3.2 Randomly select the verification code blocks to be exchanged, and obtain the exchange list TransList = ["0-3", "1-2"].

[0085] The swap list TransList, rotation list RotAngList, cutting point list XList and verification code picture are processed by the program. The verification code picture is img. Taking the Python language representation as an example, the i-th verification code block after segmentation is img[:,XList[i]:XList[i+1],:], and the first image list ImgList of the verification code block is generated. The values ​​at both ends of the first image list ImgList are:

[0086] ImgList[0]=img[:,0:XList[0],:];

[0087] ImgList[N-1]=img[:,XList[N-2]:w,:];

[0088] According to the swap list TransList, the position of the verification code block is adjusted to obtain the second image list of the adjusted verification code block; according to the rotation list RotAngList, the verification code block is rotated and adjusted in angle, and all the verification code blocks are traversed to rotate the verification code block. When the verification code block Ei is rotated, it is determined whether the verification code block Ei has been adjusted in position, that is, whether the label of the verification code block Ei exists in the position m of the element "mn" in the swap list TransList; if not, the verification code block Ei cylinder is rotated and adjusted in angle according to the value of RotAngList[i]; if so, the verification code block Ei cylinder is first rotated and adjusted in angle according to the value of RotAngList[i], and then the Ej cylinder is rotated in the opposite direction with the same value. It should be noted that Ei and Ej are an element "Ei-Ej" in the swap list TransList. When it is a verification code block When the label Ei and the label Ej of the verification code block are an element in the interchange list TransList, the angle rotation adjustment of the verification code block Ei corresponding to "Ei-Ej" will drive the angle rotation adjustment of the verification code block Ej with the same angle value in the opposite direction, but the angle rotation adjustment of the verification code block Ej will not drive the angle rotation adjustment of the verification code block Ei with the same angle value in the opposite direction; the angle rotation adjustment of the verification code block Ej corresponding to "Ej-Ei" will drive the angle rotation adjustment of the verification code block Ei with the same angle value in the opposite direction, but the angle rotation adjustment of the verification code block Ei will not drive the angle rotation adjustment of the verification code block Ej with the same angle value in the opposite direction;

[0089] Figure 3 Schematic diagram of the visibility area in a specific embodiment of the present invention is shown. Figure 3 As shown, according to the information after position adjustment and angle rotation adjustment, the verification code blocks to be verified are formed in the second order, and the visibility area is obtained on the Y axis in proportion, that is, Figure 3 The area within the dotted box is invisible to the client user.

[0090] Figure 4 FIG. 1 shows a schematic diagram of a picture block of a verification code block in a specific embodiment provided by the present invention. Figure 4As shown, since the segmented verification code picture is used to generate a verification code block, the non-adjacent edges of the picture blocks are connected. Taking the verification code picture block corresponding to the first verification code block as an example, the formula ImgList[0]=img[:,0:XList[0],:] represents the picture of the first verification code block, with a fixed width and RGB (color system) channel number. When the picture of the first verification code block is w0, that is, XList[0]=w0, then ImgList[0]=img[0:h+1,0:w0+1,:], and the range it represents is Figure 4 The range of the shaded part shown in the figure; when the range of the visibility area is (0.25h, 0.75h), the array dimension can be simplified to obtain ImgList[0]=img[0:h+1], the one-dimensional array length is h, that is, the image height, the client user's visibility area is img[0.25*h:0.75*h+1], and the visibility area assignment during rotation is expressed as: visImg[x]=img[(x+T)%h], T is the distance moved when sliding the cylinder up and down, and % is the remainder of h, thereby achieving the connection between the head and the tail.

[0091] In an optional embodiment of the present invention, step 16 includes:

[0092] Verify the position of the target verification code block and the position of the original verification code block in terms of position and / or inclusion of the image block;

[0093] If the verification results are consistent, the image block of the target verification code block is verified with the image block of the original verification code block. If they are consistent, the verification result is passed.

[0094] In this embodiment, the verification of the target verification code block of the client includes position verification and image block matching verification. The position verification of the target verification code block can be performed by verifying the number of the target verification code block with the number of the original verification code block. When the numbers are consistent, the position verification passes. When the numbers are inconsistent, the verification result can be directly fed back to the client as a failure. The position and image block of the target verification code block and the original verification code block are verified, and the verification method is simple and effective.

[0095] Match the image block of the target verification code block with the image block of the original verification code block. Preferably, the hash value of the image can be used to match the image block of the original verification code block with the image block of the target verification code block in sequence. If all match, the verification is successful, and the verification result is successful, and the verification result is sent to the client as successful; if the verification is not successful, the verification result is failed, and the verification result is sent to the client as failed; wherein, the hash value includes difference hash, mean hash, perceptual hash and wavelet hash, etc.

[0096] In a specific embodiment, the verification code image is divided into 5 blocks, which are numbered from X0 to X4. When the server generates the verification code block to be verified, the position and / or angular rotation of the original verification code block is adjusted, and the adjusted verification code block to be verified is renumbered from Y0 to Y4. The numbers are sent to the client along with the verification code block to be verified. After receiving the number of the target verification code block sent back by the client, Y0 to Y4 are replaced with X0 to X4 according to the corresponding rules when renumbering. When the number of the target verification code block is consistent with the number of the original verification code block, the position verification is passed; if not, the verification result can be directly fed back to the client as failure; as shown in Table 1:

[0097] Original verification code block X0 X1 X2 X3 X4 Verification code block to be verified X3 X1 X2 X0 X4 Renumbered verification code block to be verified Y0 Y1 Y2 Y3 Y4 Target verification code block Y3 Y1 Y2 Y0 Y4 The converted target verification code block X0 X1 X2 X3 X4

[0098] Table 1

[0099] As shown in Table 1, the original verification code blocks are numbered X0, X1, X2, X3, and X4 in sequence; the verification code blocks to be verified after position adjustment and / or angle rotation adjustment are numbered X3, X1, X2, X0, and X4 in sequence; before being sent to the client by the server, the verification code blocks to be verified are renumbered, and the renumbered blocks are Y0, Y1, Y2, Y3, and Y4 in sequence; the target verification code blocks submitted by the client are numbered Y3, Y1, Y2, Y0, and Y4 in sequence. According to the corresponding rules when renumbering the target verification code blocks submitted by the client, the target verification code blocks submitted by the client are numbered X0, X1, X2, X3, and X4, which are consistent with the numbers of the original verification code blocks. Therefore, the position verification result in Table 1 is passed;

[0100] Match the image block of the target verification code block with the image block of the original verification code block. First, grayscale the image block using the difference hash method to remove the color factor in the image block. After grayscale, there is only one channel, and the processing speed is faster. Adjust the image size to 9*8, ignore the aspect ratio of the image block of the original verification code block, which is more conducive to judging image similarity. Calculate the difference and generate a 64-bit hash value. The 64-bit hash value can be obtained by the formula p[x]>p[x+1]=1else0. Compare the hash values ​​and use the Hamming distance to determine whether the hash values ​​are the same. If they are the same, the verification result is passed and the verification result is sent to the client. If not, the verification result is failed and the verification result is sent to the client.

[0101] It should be noted that if color must be considered, it can also be processed separately according to RGB channels and then unified at the end; the difference is the difference between two adjacent numbers, and 9 values ​​can get 8 differences.

[0102] Figure 5FIG1 shows a flow chart of a verification method for a verification code applied to a client provided by another embodiment of the present invention. Figure 5 As shown, the method includes the following steps:

[0103] Step 51, receiving the verification code block to be verified and prompt rule information;

[0104] Step 52: adjusting the position and / or rotation angle of the verification code block to be verified according to the prompt rule information to obtain a target verification code block;

[0105] Step 53: Send the target verification code block to the server;

[0106] Step 54: Receive the verification result of the target verification code block from the server.

[0107] In this embodiment, the user of the client receives the verification code block to be verified and the prompt rule information generated by the server, and adjusts the position and / or angle of the verification code block to be verified according to the prompt rule information to obtain a target verification code block; sends the target verification code block to the server for verification to obtain a verification result; when the verification of the verification code is correctly completed according to the prompt rule information, the verification result is passed; when the verification of the verification code is not correctly completed according to the prompt rule information, the verification result is failed.

[0108] Figure 6 The following is a flow chart showing the process of adjusting the position and / or rotation angle of a verification code block to be verified by a user according to an embodiment of the present invention. Figure 6 As shown, in a specific embodiment, the client obtains the vertical distance obtained by the user through gesture movement, thereby obtaining the value of T. Since the user can see the visibility area, the image within the visibility area can be assigned and displayed through visImg[x]=img[(x+T)%h], thereby enabling the verification code block to be verified to slide up and down arbitrarily. The user of the client can see several verification code blocks to be verified arranged in sequence along the X-axis direction, showing the visibility area of ​​the verification code block to be verified generated by the server. Each verification code block to be verified can be slid up and down to achieve the purpose of rotating and adjusting the angle of the verification code block to be verified, and the purpose of previewing the surface area of ​​the verification code block to be verified can be achieved; at the same time, the verification code block to be verified can also be dragged and swapped;

[0109] Optionally, the user slides the verification code block to be verified up and down to realize the angle rotation adjustment of the verification code block to be verified, and the picture images in the visible area are matched with each other through the angle rotation adjustment of the verification code block to be verified, and the adjustment operation is completed and submitted for verification. When the user adjusts the position of the verification code block to be verified, the verification code block a to be verified and the verification code block b to be verified are exchanged after the linkage relationship is created, and the effect of the angle rotation adjustment of all verification code blocks to be verified is reset, that is, the user needs to re-rotate each cylinder, the user needs to readjust, and there is a linkage relationship at this time, which increases the difficulty and complexity of the operation.

[0110] It should be noted that this method is a method corresponding to the above-mentioned method applied to the server. All implementation methods in the above-mentioned verification code verification method embodiment applied to the server are applicable to the embodiment of this method and can achieve the same technical effect.
