Description

Technical Field

[0001] The present invention relates to the technical field of verification codes, and in particular to a verification method, device and equipment for verification codes. Background Art

[0002] Current technology generates verification codes in many forms, such as random combinations of numbers and letters, images containing specific text or elements, randomly generated binary arithmetic operations, and sliding verification codes. Among the numerous verification code input schemes, the majority are numbers and letters. Given the randomness of the verification code, most schemes require relatively few user actions, such as entering numbers and letters or sliding a slider to a specific position, thus reducing machine processing costs. Furthermore, even verification codes that require searching for specific objects in an image or selecting images containing objects, while requiring more user actions, have significantly advanced object detection and recognition due to advances in machine learning. Consequently, existing verification code display formats inevitably present the following issues: First, verification codes are easily recognized by machines, leading to cracking and failing to effectively prevent malicious activities such as automated batch registrations. Second, each verification code type is formatted specifically. For example, numeric verification codes are fixed-length, while image verification codes often rely on a matching principle, resulting in a shorter user interaction process. Summary of the Invention

[0045] 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.

[0046] 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:

[0047] Step 11, generate a verification code image;

[0048] Step 12: Generate a verification pass color block based on the color information of the verification code image;

[0049] Step 13, generating an interference color block different from the verification-passed color block based on the verification-passed color block;

[0050] Step 14: Send the prompt rule information, the verification code image, the at least one color block, and the interference color block to the client;

[0051] Step 15, receiving at least one target color block selected by the user from the at least one color block and the interference color blocks;

[0052] Step 16: perform verification based on the at least one target color block, obtain a verification result, and send it to the client.

[0053] This embodiment generates a verification code image on a server, processes the verification code image to obtain a verification-passing color block, and then generates an interference color block different from the verification-passing color block. The prompt rule information, the verification code image, the verification-passing color block, and the interference color block are sent to a client. At least one target color block selected by the client from the verification-passing color block and the interference color block based on the verification code image is verified to obtain a verification result, which is then sent to the client. The verification-passing color block is a color block that corresponds to a color in the verification code image, and the color of the interference color block is preferably different from that of the verification-passing color block. By providing verification code images with multiple colors, the complexity and computational process of completing verification code verification for a client user are improved, effectively resolving the issues of verification codes being easily recognized by machines and the short user interaction process. This achieves diversity in the styles and displays of verification codes, increasing the difficulty of cracking the verification code and the number of interactions.

[0054] Figure 2The following is a schematic diagram showing a verification code image, a verification passed color block, and an interference color block in the verification method of the verification code provided by an embodiment of the present invention. Figure 2 As shown, in a specific embodiment 1, box a shows a verification code picture, box b shows a verification passed color block and an interference color block. It can be seen from box a that the verification code picture includes verification passed color block 1, verification passed color block 2 and verification passed color block 3, and box b includes verification passed color block 1, verification passed color block 2, verification passed color block 3, interference color block 4, interference color block 5, interference color block 6, interference color block 7, interference color block 8, interference color block 9, interference color block 10 and interference color block 11.

[0055] In an optional embodiment of the present invention, step 12 includes:

[0056] Step 121: performing color clustering processing on the verification code image to obtain a color clustering result;

[0057] Step 122, setting the color block attributes of the color block that has passed the verification according to the color clustering result;

[0058] Step 123: Generate a verified color block according to the color block attributes.

[0059] Optionally, the color block attribute includes the color of the color block and / or the proportion of the color in the verification code image; the color of the color block is the color in the verification code image or a color of a corresponding hue.

[0060] In this embodiment, a color clustering process is performed on the verification code image, and a color clustering process is performed according to the color of each pixel in the verification code image to obtain a color clustering result. According to the color clustering result, a color block attribute of the verification-passing color block is set, and a verification-passing color block is generated. The color block attribute includes the color of the color block and / or the proportion of the color in the verification code image. The color of the color block is the color in the verification code image or the color of the corresponding hue. The color corresponding hue refers to a hue within a preset offset range from the color hue in the verification code image. The color clustering process preferably uses a k-means clustering algorithm.

[0061] Preferably, it can be achieved by:

[0062] image=image.reshape((image.shape[0]*image.shape[1],3)) converts the verification code image;

[0063] Among them, shape[0] is the width of the verification code image, and shape[1] is the height of the verification code image;

[0064] The converted verification code image is clustered by the k-means clustering algorithm, and the number of cluster centers c∈[2,3,4,…] is the color of the verification color block in the verification code image or the color of the corresponding hue. The more cluster centers there are, the more verification color block colors there are in the verification color block diagram corresponding to the verification code image, and the more difficult it is for the client to process. Each verification color block in the verification color block diagram corresponds to a proportion value, and a matrix can be used to represent the proportion values ​​of all verification color blocks in a verification color block diagram. The sorting of the verification color blocks in the verification color block diagram in the matrix can preferably be sorted from large to small, but this application is not limited to this, and can also be sorted by the order of other rules. The order matrix of each verification color block is recorded as index=[first color block number, second color block number,…,nth color block number], where n is a positive integer.

[0065] According to the matrix generated by the proportion values ​​of all verified color blocks in the verified color block diagram and the color information of all verified color blocks, the attribute [color, proportion] of each verified color block in the verified color block diagram is obtained, and the matrix of the verified color block attributes corresponds to the sequential matrix index of each verified color block.

[0066] Figure 3 FIG. 1 shows a schematic diagram of color clustering processing provided by an embodiment of the present invention. Figure 3 As shown, in a specific embodiment, box a shows a verification code picture, wherein the verification code picture includes verification pass color block 1, verification pass color block 2 and verification pass color block 3, and the verification pass color block 1, verification pass color block 2 and verification pass color block 3 in the verification code picture are converted into a verification pass color block picture according to the proportion of all pixel points corresponding to the color of the verification pass color block in the verification code picture through color clustering processing; wherein the height of the verification pass color block picture is a preset fixed value, and the width of the verification pass color block is determined by the proportion of all pixel points corresponding to the color of the verification pass color block in the verification code picture, and in the three verification When the heights of the color blocks are the same, the proportion of all pixels corresponding to the color of the verified color block 1 in the verification code image is R1, the proportion of all pixels corresponding to the color of the verified color block 2 in the verification code image is R2, and the proportion of all pixels corresponding to the color of the verified color block 3 in the verification code image is R3. It can be seen from the verification code image a that R1>R2>R3. When the height of the three verified color blocks is a preset fixed value, the width of the verified color block 1 is W1, the width of the verified color block 2 is W2, and the width of the verified color block 3 is W3. The widths from large to small are W1>W2>W3.

[0067] Figure 4FIG. 1 shows a schematic diagram of color clustering processing provided by an embodiment of the present invention. Figure 4 As shown, in a specific embodiment, the verification code image includes a verification pass color block 13, a verification pass color block 14, and a verification pass color block 15. The verification pass color block 13, the verification pass color block 14, and the verification pass color block 15 in the verification code image are converted into a verification pass color block image according to the proportion of all pixels corresponding to the color of the verification pass color block in the verification code image through color clustering processing; wherein the height of the verification pass color block image is a preset fixed value, and the width of the verification pass color block is determined by the proportion of all pixels corresponding to the color of the verification pass color block in the verification code image. When the three verification-passed color blocks have the same height, the color of the verification-passed color block 13 is black, and the proportion of all pixels corresponding to the color of the verification-passed color block in the verification code image is R13 = 0.872. The color of the verification-passed color block 14 is yellow, and the proportion of all pixels corresponding to the color of the verification-passed color block in the verification code image is R14 = 0.067. The color of the verification-passed color block 15 is red, and the proportion of all pixels corresponding to the color of the verification-passed color block in the verification code image is R15 = 0.061.

[0068] It can be seen that R13>R14>R15. The matrix obtained by sorting the proportions of all the verified color blocks in the verified color block diagram from large to small is [0.872, 0.067, 0.061]. The order is recorded as index = [13, 14, 15]. The matrix of the verified color block attributes in the verified color block diagram is [[black, 0.872], [yellow, 0.067], [red, 0.061]]. The matrix of the verified color block attributes corresponds to the order matrix.

[0069] If the percentage of all the verified color blocks in the verified color block diagram is sorted according to other rules to obtain a matrix of [0.872, 0.061, 0.067], the order matrix is ​​recorded as index' = [13, 15, 14];

[0070] When the height of the three verified color blocks is a preset fixed value, the width of the verified color block 13 is W13, the width of the verified color block 14 is W14, and the width of the verified color block 15 is W15. The widths from large to small are W13>W14>W15. Therefore, the verified color block diagram is spliced ​​in the order of the size of the verified color blocks from large to small as verified color block 13, verified color block 14 and verified color block 15.

[0071] In an optional embodiment of the present invention, step 13 includes:

[0072] Step 131, using a random function to generate at least one interference color block according to the color of the verification-passed color block, wherein the color of the interference color block is different from the color of the verification-passed color block; or

[0073] Step 132 : generating at least one interference color block according to the color of the verified color block and a preset rule.

[0074] In this embodiment, the color block attributes of the interference color block need to be different from the color attributes of the verification pass color block corresponding to the verification code image. Preferably, at least one interference color block with color block attributes different from the color attributes of the verification pass color block corresponding to the verification code image can be generated by a random function, and at least one interference color block with color attributes different from the color block corresponding to the verification code image can be generated by a preset rule. It should be noted that by adjusting the prompt rule information, the difficulty of using the verification code can be adjusted. The closer the color tone of the generated interference color block is to the color tone of the verification pass color block corresponding to the verification code image, the greater the difficulty of using the verification code. The interference color block can preferably be numbered with "#" as the sequence in the sequential matrix index.

[0075] In an optional embodiment of the present invention, step 16 includes:

[0076] Step 161, obtaining a first order matrix corresponding to the at least one target color block;

[0077] Step 162: splicing the at least one verified color block according to a preset splicing rule to obtain a verified color block diagram and a second sequence matrix corresponding to the verified color block diagram;

[0078] Step 163, verifying the second order matrix corresponding to the verified color block image and the first order matrix corresponding to the at least one target color block. If the verification results are consistent, the verification is successful.

[0079] Step 164: Send the verification result to the client.

[0080] In this embodiment, the server sends the verification code image, the verification-passed color block and the interference color block to the client, and the client displays the received verification code image, the verification-passed color block and the interference color block. The user selects a target color block from the verification-passed color block and the interference color block according to the prompt rule information, and feeds back at least one selected target color block to the server. The server receives at least one target color block selected by the user according to the prompt rule information based on the verification code image, and obtains a first order matrix corresponding to the target color block fed back by the client according to the order corresponding to the color block attributes of the target color block. The server verifies the at least one target color block, that is, verifies the first order matrix. If it is the same as the second order matrix generated by the verification-passed color block in the verification code image, the splicing is successful and the verification is passed; if it is different from the second order matrix generated by the verification-passed color block in the verification code image, the splicing is unsuccessful and the verification cannot be passed, and the server sends the verification result to the client.

[0081] Figure 5 FIG1 shows a schematic diagram of the use of a verification code in a verification method of a verification code provided by an embodiment of the present invention. Figure 1 and Figure 5 As shown, in a specific embodiment, box a shows a verification code picture, box b shows a verification pass color block and an interference color block. It can be seen from box a that the verification code picture includes verification pass color block 1, verification pass color block 2 and verification pass color block 3, box b includes verification pass color block 1, verification pass color block 2, verification pass color block 3, interference color block 4, interference color block 5, interference color block 6, interference color block 7, interference color block 8, interference color block 9, interference color block 10 and interference color block 11, box c is a target color block selection box. When the client needs to use the verification code, the user needs to select the correct target color block and verify the target color block according to the usage rules. The client will explain the usage rules of the verification code to the user. Figure 5The usage rule of the verification code in is to select all the verification-passing color blocks corresponding to the verification code image from the verification-passing color blocks and the interference color blocks, and arrange them in descending order; the user can select the target color block in box b through the client and move the target color block to the target position in the target color block selection box. The client sends the selected target color block to the server for verification. If the order matrix of the received target color block is index1 = [#,#,#], which is different from the order matrix of the verification-passing color blocks in the verification code image, index = [0,1,2], the splicing is unsuccessful and the verification cannot be passed; if the order matrix of the received target color block is index2 = [0,#,2], which is different from the order matrix of the verification-passing color blocks in the verification code image, index = [0,1,2], the splicing is unsuccessful and the verification cannot be passed; if the order matrix of the received target color block is index3 = [0,1,2], which is the same as the order matrix of the verification-passing color blocks in the verification code image, index = [0,1,2], the splicing is successful and the verification is passed.

[0082] It should be noted that in this application, there is no restriction on the shapes of the verification-pass color blocks and interference color blocks sent by the server to the client. In addition to rectangular color blocks, they can also be triangular color blocks, circular color blocks, square color blocks, ring-shaped color blocks, and irregular shapes, etc. The usage rules of the verification code correspond to the verification method of the verification code, and the usage rules of the verification code and the verification method of the verification code can preferably be adaptively adjusted according to the verification code image, the shape of the verification-pass color block, and the shape of the interference color block.

[0083] Figure 6 FIG1 shows a color block diagram obtained by verifying a verification code using a circular color block in a verification method provided by an embodiment of the present invention. Figure 1 and Figure 6 As shown, Figure 1 In the verification code picture in box a, the verification passed color block and interference color block in box b can also be used to obtain the target color block selected by the user through concentric rings. This method uses the radius of the concentric rings to prompt the user. The user can select the target color block according to the size of the proportion of the corresponding verification passed color block in the verification code picture. After the correct selection, the rings can be interlocked, otherwise the concentric circles cannot be formed. In the verification code picture a, the proportion of verification passed color block 1 R1> the proportion of verification passed color block 2 R2> the proportion of verification passed color block 3 R3, so, Figure 6 The color block diagram in the concentric rings from the outside to the center is verification passed color block 1, verification passed color block 2 and verification passed color block 3, which means that the server verification has been passed.

[0084] Figure 7The figure shows the color block diagram obtained by verifying the color of the verification code image in the verification method provided by the embodiment of the present invention. Figure 7 As shown, in a specific embodiment, box d is a verification code image. The colors shown in the verification code image are gradient colors, and the user cannot intuitively determine the specific color block it corresponds to. Therefore, the verification pass color block and the interference color block are presented in a color wheel of cold and warm tones. The usage rule of this verification code is to select the target color block based on the prompted color wheel. The color wheel has obvious cold and warm color changes. According to the given verification code image, a cold color, a warm color, or a similar color block area selected in the color wheel is selected to complete the verification;

[0085] Figure 8 The figure shows a color block diagram obtained by verifying the color selection in the color wheel in the verification method of the verification code provided by the embodiment of the present invention. Figure 7 and Figure 8 As shown, preferably, the usage rule of the verification code is that when selecting the cold color and warm color information corresponding to the verification code picture, the word "warm" representing the warm color can be moved to the box f according to the prompt, and the verification is successful;

[0086] Preferably, the verification code usage rule is to select three color block areas in the color palette that are similar to the verification code image. If the user selects any three color areas from the color palette of color blocks 16, 17, 18, 19, and 20 that are closest in hue to the verification code image, verification is successful. It should be noted that, by adjusting the preset rules, it is preferred to add verification conditions such as sorting in order according to color proportion values, thereby increasing the difficulty of using the verification code.

[0087] Figure 9 FIG1 shows a schematic diagram of adjusting the number of cluster centers and thus adjusting the verification difficulty of the verification code in the verification method of the verification code provided by the embodiment of the present invention. Figure 1 and Figure 9 As shown, in a specific embodiment, the box g is a verification code picture, and the cluster center of the verification code picture g is compared Figure 1 The verification code image a in the box has more cluster centers, so when selecting the target color block in the color block diagram, the more colors of the verification color blocks and interference color blocks need to be selected, and the greater the difficulty. At the same time, it can be seen from the color block diagram corresponding to the verification code image g in the box h that the difference in adjacent color tones is small and the colors are relatively close, and its difficulty is greater than that of Figure 1 The larger the verification code image a is, the larger the color ratio of the color blocks in the adjacent areas is. Figure 1 The verification code image a is closer and more difficult.

[0088] Figure 10The following is a schematic diagram showing how to adjust the verification difficulty of a verification code image by adjusting the shape of a color block in a verification code verification method provided by an embodiment of the present invention. Figure 1 and Figure 10 As shown, the generated verification-pass color blocks and interference color blocks are not regular rectangles, but combinations of rectangles or irregular shapes, namely, target color block 1-1, target color block 2-1, and target color block 3-1. Color blocks with the same color block attributes [color, proportion] will have multiple styles for the client user to choose. The user selects the appropriate color, width, and shape for splicing according to the prompt rule information to obtain a rectangle or other regular pattern, a color block diagram composed of verification-pass color block 1, verification-pass color block 2, and verification-pass color block 3. According to the prompt rule information, a color block diagram composed of target color block 1-1, target color block 2-1, and target color block 3-1 can be obtained.

[0089] Figure 11 FIG. 1 shows a schematic diagram of a verification method for a verification code provided by an embodiment of the present invention, wherein verification is performed by selecting the color of a color block. Figure 11 As shown, a colorless shape can be provided in the verification code image. The shape has different sizes to correspond to the proportion of the color block to be selected. Through the color editor, the user follows the color required by the prompt rule information, and the server verifies it.

[0090] The solution of the present invention generates a verification code image; generates a verification-pass color block according to color information of the verification code image; compares the verification-pass color block to generate an interference color block different from the verification-pass color block; sends prompt rule information, the verification code image, the verification-pass color block and the interference color block to a client; receives at least one target color block selected from the verification-pass color block and the interference color block and sent by the client; verifies whether the target color block is the same as the verification-pass color block, obtains a verification result, and sends it to the client; realizes the diversity of verification code styles and displays, and increases the difficulty of cracking the verification code and the number of interactions.

[0091] Figure 12 FIG1 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 12 As shown, the method includes the following steps:

[0092] Step 12a, receiving prompt rule information, a verification code image, at least one color block, and an interference color block;

[0093] Step 12b, selecting at least one target color block based on the verification code image, the at least one color block, and the interference color block according to the prompt rule information, and sending the selected target color block to the server;
