Detailed ways

In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

Fig. 1 is a flowchart of the verification code verification method provided by the embodiment of the present invention. As shown in Fig. 1, the verification code verification method provided by the embodiment of the present invention is applied to the server end, and specifically includes the following steps:

Step 101: Generate verification code information and verification code verification information according to the received verification code generation request.

In the embodiment of the present invention, the verification code is an image verification code, and the image verification code requires the user to adjust the disrupted image blocks in the image to complete the verification.

In the embodiment of the present invention, the verification code information includes the image to be verified and verification rules.

The image to be verified includes multiple image blocks obtained by splitting the original image, and the positions of the multiple image blocks in the original image are disrupted by adjusting the offset angle of the center of gravity.

The verification rule is used to describe the manner of verifying the image to be verified.

The verification code check information is used to describe the correct position of the image block in the image to be verified.

The verification code information can have various styles. In this embodiment of the present invention, the verification code information is first verification code information. The first verification code information includes a first image to be verified and a first verification rule; the first image to be verified includes a plurality of image blocks, the plurality of image blocks are obtained by splitting the original image, and the plurality of image blocks are in The position in the original image is disrupted by binding adjacent image blocks to exchange positions; the first verification rule is used to describe the method of verifying the first image to be verified.

Correspondingly, the verification code verification information is first verification code verification information, and the first verification code verification information is used to describe the correct position of the image block in the first image to be verified.

Specifically, the way of binding adjacent image blocks to exchange positions means that there are one or more image blocks with the same size and shape at the adjacent position of an image block (called image block A), from the An image block B is selected from one or more adjacent image blocks, and the selected image block B is bound to the image block A to exchange positions, realizing an operation of exchanging positions of adjacent image blocks.

The first image to be verified and the verification information of the first verification code can be generated by binding adjacent image blocks to exchange positions. Specifically, it includes the following steps:

Segmenting an image block from an original image, numbering the image block, and using the association relationship information between the image block and the spatial position of the image block as the first verification code verification information;

Generate a sequence of random numbers;

According to one or more random numbers in the random number sequence, the image block corresponding to the image block number is exchanged with the adjacent image block to generate the first image to be verified.

FIG. 2 is an example diagram of adjusting image verification codes of disrupted image blocks in an image by exchanging positions of adjacent image blocks in an embodiment of the present invention. Taking Fig. 2 as an example, an original image is divided into multiple image blocks on the upper left of Fig. 2 , and these image blocks are respectively numbered, such as 1, 2, 3, . . . , 14. Before the positions of these image blocks are transformed, there is an association relationship with their spatial positions. After these image blocks are subsequently disrupted, this association relationship is destroyed. In order to check whether the user's verification operation is correct in the subsequent steps, the association relationship information between the image block and the spatial position of the image block is used as the first verification code verification information. For example, the numbers of the image blocks cut out from the mother image are 1, 2, 3, and 4 respectively, and the numbers of the spatial positions occupied by these image blocks before being shuffled are A, B, C, and D. Then the first verification code check information may be [A-1]/[B-2]/[C-3]/[D-4].

Before shuffling these image blocks, a sequence of random numbers is first generated. This random number sequence is also called a randomization seed in the embodiment of the present invention.

In the embodiment of the present invention, the randomization seed is generated according to the system time and the client that initiates the verification code request. Since the randomization seed depends on the system time and the client that initiates the verification code request, the verification code requested by the same client at different times will not be the same; similarly, the verification code requested by different clients at the same time Nor will it be the same.

Here is an example: Assume that the request time is "2019-01-25 17:25:46", and the obtained system time is: 1548407738000, and the number of digits of the time is truncated to 407738. Assuming that the hash code of the current object is 1163157884, it is also intercepted to 631578. Wherein, in the embodiment of the present invention, the interception position of the digits of the system time is fixed during the interception process, that is, remove the high four digits and take the middle 6 digits; the interception position of the digits of the hash code is correspondingly "random", which is desirable The highest 6 digits may also be the lowest 6 digits, or as assumed above, the middle 6 digits. After obtaining two random numbers according to the system time and the client that initiated the verification code request, perform a custom addition operation on the two random numbers. The calculation process is as follows:

The result of the calculation is 038206.

After obtaining a random number, the randomization seed of the image block can be obtained according to the random number.

In the embodiment of the present invention, the one-digit seed sequence can be obtained according to the random number 038206 as follows: 0, 3, 8, 2, 0, 6. A value is selected from these one-digit seed sequences for image blocks (assuming that the number of image blocks segmented from the parent image is less than or equal to 6) as a randomization seed. Depending on the application scenario, the specific implementation of generating a random seed from a random number will vary. There will be further descriptions in other embodiments of the present invention.

After the randomization seed is obtained, the image block corresponding to the image block number and the adjacent image block can be swapped according to the randomization seed to generate the first image to be verified.

For example, in the previous example, the single-digit seed sequence consisted of: 0, 3, 8, 2, 0, 6. According to these seeds, the adjacent image block exchange position operation is performed on the corresponding numbered image block, such as first performing the adjacent image block exchange position operation on the image block numbered 0 (if there are more than An adjacent image block, randomly select one of the adjacent image blocks to perform the swap position operation), and then perform the adjacent image block swap position operation on the image block numbered 3, ..., until the image block numbered 6 Carry out the operation of exchanging positions of adjacent image blocks. After multiple transformations, the numbering order of image blocks has changed. The finally generated image is the first image to be verified.

The upper right image in FIG. 2 is the first image to be verified generated by exchanging positions of the image blocks in the upper left image in FIG. 2 .

The first image to be verified specifically includes: information about the image block, information about the parent image of the image block, and information about the verification method. Wherein, the parent image of the image block refers to the image from which the image block originates. The information of the image block includes the shape and size of the image block, the number of the image block, and the position of the image block in the parent image after being scrambled. The image block information is private information of each image block, and different image blocks correspond to different information. The verification mode information reflects the verification mode followed by all image blocks, for example, all image blocks in the first image to be verified follow the verification mode of exchanging positions of adjacent image blocks.

The first verification code information also includes a first verification rule, which is used to describe the method of verifying the first image to be verified. For example, a possible first verification rule is "exchanging adjacent image blocks position and restore the original image".

In the embodiment of the present invention, the verification code information can also be other styles of verification code information, such as the verification obtained by disrupting the image blocks by combining position movement and angle rotation mentioned in the embodiments after the present invention Code information, or the verification code information obtained by disrupting the image blocks by angular rotation, or other verification code information obtained by disturbing the image blocks by adjusting the offset angle of the center of gravity.

Step 102. Send the verification code information to the client, so that the client displays the verification code information.

Step 103: Receive the verification result returned by the client, compare the verification result with the verification code verification information, and complete the verification.

In the embodiment of the present invention, the verification result is the result of the verification operation completed by the user on the client terminal. How to generate verification results will be further described in other embodiments of the present invention.

The verification code verification information has been described in detail before. The verification result returned by the client includes the correlation between the image blocks in the image and their spatial positions after the verification of the image to be verified. Compare the verification result with the verification code verification information. If the comparison results are consistent , the verification is passed, otherwise, the verification is not passed.

Still take the first verification code information mentioned in the embodiment of the present invention as an example. The lower figure in Figure 2 is the figure generated after the verification operation on the upper right figure in Figure 2. Comparing it with the upper left figure in Figure 2, it can be found that the two are the same, so the verification is passed.

The verification code verification method provided by the embodiment of the present invention increases the complexity of the verification code and increases the difficulty of cracking the verification code, thereby better avoiding being recognized by machines and improving network security.

Based on any of the above embodiments, Fig. 3 is a flow chart of the verification code verification method provided by the embodiment of the present invention. As shown in Fig. 3, the verification code verification method provided by the embodiment of the present invention is applied to the client, and specifically includes the following steps :

Step 301: Send a verification code generation request, so that the server generates verification code information and verification code verification information according to the verification code generation request.

The verification code information includes an image to be verified and a verification rule; the image to be verified includes a plurality of image blocks, the plurality of image blocks are obtained by splitting the original image, and the plurality of image blocks in the original image The position is disturbed by adjusting the offset angle of the center of gravity.

The verification code information can have multiple styles, and the styles reflect the verification method of the verification code. For numerical sorting, selecting specified characters from candidate characters is two different verification code styles. In this embodiment of the present invention, the verification code information is first verification code information.

The first verification code information includes a first image to be verified and a first verification rule; the first image to be verified includes a plurality of image blocks, the plurality of image blocks are obtained by splitting the original image, and the plurality of images The positions of the blocks in the original image are disrupted by adjusting the offset angle of the center of gravity; the first verification rule is used to describe the method of verifying the first image to be verified.

Correspondingly, the verification code verification information is the first verification code verification information, and the first verification code verification information is used to describe the correct position of the image block in the first image information to be verified.

In the embodiment of the present invention, the verification code information can also be other styles of verification code information, such as the verification obtained by disrupting the image blocks by combining position movement and angle rotation mentioned in the embodiments after the present invention Code information, or the verification code information obtained by disrupting the image blocks by angular rotation, or other verification code information obtained by disturbing the image blocks by adjusting the offset angle of the center of gravity.

In this embodiment of the present invention, the operation of sending a verification code generation request may be triggered in various ways. For example, after the user clicks the button "Get Verification Code" on the verification interface, a verification code generation request is sent to the server. For another example, the client sends a verification code generation request to the server after capturing that the user has input other verification information (such as user name and password) on the verification interface except the verification code. In the embodiment of the present invention, the latter method can be adopted, which helps to reduce the waiting time of the user.

Step 302: Present the image to be verified and the verification rule according to the received verification code information, so that the user can perform verification operation on the image to be verified according to the verification rule.

In this step, the first verification code information is still used as an example. It has been mentioned above that the first image information to be verified may specifically include image block information, image block master image information, and verification mode information. In the embodiment of the present invention, the first image to be verified and the first verification rule are displayed by drawing. When drawing, the parent image of the image block and the image block are drawn separately. Since the image block information includes the shape and size information of the image block, as well as information such as the number information of the shuffled image block, the generated image to be verified remains in a "chaotic" state. As a preferred implementation manner, the center of gravity is used to draw the position of the image block during drawing.

After the image block is drawn, it is also necessary to set the attributes of the image block according to the verification mode information in the first image information to be verified. For example, set the properties of the image block to rotate, translate.

The drawing of verification rules is common knowledge of those skilled in the art, so it will not be repeated here.

Step 303: Generate a verification result according to the user's verification operation, and send the verification result to the server, so that the server compares the verification result with the verification code verification information to complete the verification.

Users can perform verification operations according to the image to be verified and the verification rules. During the verification operation, operations such as clicking and dragging will be performed on the disrupted image blocks in the image to be verified. Driven by these operations, image blocks will change accordingly. Capturing the information contained in these changes can form the verification result.

For the first image to be verified, the user selects an image block by clicking, and the selected image block needs to be exchanged with its adjacent image block. However, in practical applications, an image block may have more than one adjacent image block, how to let the computer system automatically determine which adjacent image block should be swapped; in the verification process, the swap position operation in the previous step may not be Appropriate, how to judge in which scenarios need to resume the position swap just completed. All of these need to be realized by adopting the method provided by the embodiment of the present invention.

Specifically, this step includes:

The step of collecting information, which includes collecting the information of the image block selected by the user;

The step of exchanging positions, which includes exchanging the positions of the image block selected by the user and its adjacent image blocks;

Repeat the step of collecting information and the step of exchanging positions until the user stops the verification operation;

The image block and the information of the spatial position of the image block are used as the verification result.

Fig. 4 is a flow chart of realizing the operation of exchanging positions in the verification code verification method provided by the embodiment of the present invention. As shown in Fig. 4, the step of exchanging positions further includes:

S1. Determine the image block selected by the user, and detect whether the selected image block is bound. If it is bound, the image block is the image block bound in the last position exchange operation. Execute S2. If not Binding, performing S5; wherein, the binding describes the relationship between two adjacent image blocks whose positions are exchanged;

S2. Detect whether the selected image block is the image block that caused the position transformation in the last position exchange operation, if yes, perform position exchange (the actual operation effect is the undo operation to the previous step transformation), if not, then Release the binding relationship; wherein, the image block that causes the position change is the image block selected by the user;

S3. Search for adjacent image blocks for the selected image block in the first image to be verified according to a fixed order (such as clockwise); wherein, when searching for adjacent image blocks, preferentially select image blocks that have not undergone position transformation;

S4. Establish a binding relationship with the found adjacent image block, perform position exchange, and end the operation on the image block selected by the user;

S5. Searching for adjacent image blocks for the image block selected by the user in the image to be verified according to a fixed order (such as clockwise); wherein, when searching for adjacent image blocks, preferentially select the image block whose position has changed;

S6. Establish a binding relationship with the found adjacent image block, perform position exchange, and end the operation on the image block selected by the user.

Through the above steps, the position exchange of adjacent image blocks can be realized.

The verification code verification method provided by the embodiment of the present invention increases the complexity of verification, thereby better avoiding being recognized by machines and improving network security.

Based on any of the above embodiments, FIG. 5 is a flow chart of a verification code verification method provided by another embodiment of the present invention. As shown in FIG. 5, the verification code verification method provided by another embodiment of the present invention is applied to the server side. Specifically include the following steps:

Step 501: Generate verification code information and verification code verification information according to the received verification code generation request and the risk level of the user's operating environment.

The image to be verified includes a plurality of image blocks, the plurality of image blocks are obtained by splitting the original image, and the positions of the plurality of image blocks in the original image are disrupted by adjusting the offset angle of the center of gravity; The verification rule is used to describe the way of verifying the image to be verified; the verification code verification information is used to describe the correct position of the image block in the image to be verified.

In the embodiment of the present invention, the complexity of the verification code operation may be determined according to the risk level of the user's operating environment. A basic principle is that the higher the risk, the higher the difficulty factor of the verification code operation.

In the embodiment of the present invention, three verification codes with different complexities are provided. The first type of verification code has the highest complexity. It uses the method of exchanging the positions of adjacent image blocks to adjust the position of the disturbed image blocks in the image to be verified, so as to complete the verification. It has been described in detail in the previous embodiments of the present invention and will not be repeated here.

The complexity of the second type of verification code is medium. It adjusts the disrupted image blocks in the image through a combination of position movement and angle rotation, so as to complete the verification. For example, image blocks that have been shuffled are irregularly shaped image blocks that have been cut from an original image. These image blocks have not only moved in horizontal and/or vertical directions, but also have an are scrambled, so the user adjusts the angles of these image blocks by rotating them during verification, so that they are the same or similar to the angles before they were not scrambled, and also needs to adjust the positions of these image blocks so that they are not scrambled. The positions before the scrambling are the same or similar (the closeness means that the difference between the adjusted position of the image block and the position of the image block before being scrambled should be within a threshold range). In this type of verification code, in order to reduce the difficulty of user operations, the rotatable angle of the image block is generally set to a fixed value (for example: 45 degrees or 90 degrees clockwise or counterclockwise). FIG. 6 is an example diagram of adjusting the image verification code of a disrupted image block in an image by a combination of position movement and angle rotation in an embodiment of the present invention. In FIG. 6 , the picture on the upper left is the original image, and the image blocks numbered 1-8 are the segmented image blocks. During the process of scrambling these image blocks, the position changes and the angle rotates (because the image blocks are hexagonal, the rotation angle cannot be clearly displayed from the figure), and the upper right figure in Figure 6 is obtained. The user can only pass the verification if he restores the disturbed image block to the bottom picture in Figure 6. It should be noted that in FIG. 6 , for the purpose of clarity, the overlap of image blocks is not shown in FIG. 6 . In fact, when the image blocks are shuffled, the shuffled image blocks may overlap.

The third type of verification code has the lowest complexity, and it completes the verification by adjusting the disrupted image blocks in the image by means of angle rotation. FIG. 7 is an example diagram of an image verification code for adjusting a disrupted image block in an image by means of angular rotation in an embodiment of the present invention. The leftmost figure in Fig. 7 is the original image, and a plurality of concentric drop-shaped or drop-shaped rings (the innermost is drop-shaped, and the others are concentric drop-shaped rings) are cut out from this original image. The cut out multiple concentric drop-shaped or drop-shaped rings are rotated relative to the reference axis (such as the horizontal line and the vertical line in the figure), so as to obtain the image blocks that have been disturbed. The picture in the middle part of Fig. 7 is the image after being scrambled. Since the angles of these image blocks relative to the reference axis are disturbed, the user can adjust the angles of these image blocks by rotating them during verification, so that they are the same or similar to the angles before being disturbed (the similarity refers to the The difference between the adjusted angle and the angle of the image block before being scrambled should be within a threshold). In this verification code, the position of the image block cannot be moved, but it can be rotated at any angle around the center. The user can only pass the verification if he restores the disturbed image block to the rightmost picture in Figure 7.

For the second type of verification code and the third type of verification code, the operation of each image block is independent during the verification process, and the operation of one image block does not affect the other image block, so the complexity of these two types of verification codes The degrees are all O(n) (Note: The complexity here uses the concept of complexity in measuring computer algorithms). For the first type of verification code, the operation on one image block during the verification process will affect another image block (an adjacent image block), the current selection of the user depends on the selection of the previous step, and a rollback is required if there is an error , so the complexity of this verification code is almost O(n^m), where n is the number of image blocks, and m is the preset number of adjustments. Obviously, by increasing the complexity, it can better avoid being recognized by machines and achieve the original intention of the verification code.

Although the server can provide three types of verification codes, in practical applications, one of the verification codes will be selected and generated according to the risk of the client.

Specifically:

According to the received verification code generation request and the high-risk risk assessment result, generate first verification code information and first verification code verification information; wherein, the first verification code information includes the first image to be verified and The first verification rule; the first image to be verified includes a plurality of image blocks, the plurality of image blocks are obtained by splitting the original image, and the positions of the plurality of image blocks in the original image are bound to adjacent The way in which the image blocks are exchanged is disrupted; the first verification rule is used to describe the way to verify the first image to be verified; the first verification code check information is used to describe the first image information to be verified The correct position of the image block;

Or, generate second verification code information and second verification code verification information according to the received verification code generation request and the risk assessment result of the medium risk; wherein, the second verification code information includes the second verification code information to be verified Image and second verification rule; the second image to be verified includes a plurality of image blocks, the plurality of image blocks are obtained by splitting the original image, and the positions of the plurality of image blocks in the original image are moved by position The method combined with angle rotation is disrupted; the second verification rule is used to describe the method of verifying the second image to be verified; the second verification code check information is used to describe the second image information to be verified The correct position of the image block;

Or, generate third verification code information and third verification code verification information according to the received verification code generation request and the low-risk risk assessment result; wherein, the third verification code information includes the third verification code information to be verified Image and third verification rule; the third image to be verified includes a plurality of image blocks, the plurality of image blocks are obtained by splitting the original image, and the positions of the plurality of image blocks in the original image are rotated by an angle The method is disrupted; the third verification rule is used to describe the method of verifying the third image to be verified; the third verification code check information is used to describe the correctness of the image block in the third image information to be verified Location.

The generation process of the first verification code information and the first verification code verification information has been described in detail above, so it will not be repeated here. The following describes the generation process of the second verification code information and the second verification code verification information, and the generation process of the third verification code information and the third verification code verification information.

When generating the second verification code information and the second verification code verification information, it is also necessary to segment the image block from the original image, then generate a random number sequence, and adjust the relative coordinates and rotation angle of the center of gravity of the image block according to the random number in the random number sequence , to generate the second image to be verified. At the same time, the second verification code verification information can be obtained according to the original position information of the image block during division and the rotation angle during adjustment.

Specifically:

When generating a random number sequence, refer to the description in the generation process of the first verification code information and the first verification code verification information, you can generate a random number according to the system time and the client that initiated the verification code request, such as 038206, and then according to the random number The two-digit seed sequence is obtained as follows: 03, 38, 82, 20, 06. A value is selected from these two-digit seed sequences for image blocks (assuming that the number of image blocks segmented from the original image is less than or equal to 5) as a randomization seed. At the same time, the three-digit seed sequence can also be obtained according to the random number as follows: 038, 382, 820, 206.

When the image block is disturbed according to the randomization seed, the relative coordinates of the center of gravity and the rotation angle value of each image block can be obtained according to the value of the randomization seed based on 100%. For example, in the previous example, the two-digit seed sequence included: 03, 38, 82, 20, 06. Percentage values of 3%, 38%, 82%, 20% and 6% can be obtained from these seed sequences. These percentage values are called the relative coordinates of the center of gravity in the embodiment of the present invention, and they describe the offset ratio of the horizontal position (or vertical position), such as 3% means that the image block is moved to 3% from the left and right to the horizontal direction of the parent image s position. The second type of verification code not only needs to move the position, but also needs to rotate the angle. However, the possible rotation angle values in the second verification code are not random values, but several fixed values, such as integer multiples of 45 degrees. When disturbing the image block, taking the integer multiple of 45 degrees as an example, according to the aforementioned three-digit seed sequence and taking 360 degrees as the benchmark, 38 degrees, 22 degrees (the remainder of 382 divided by 360), 100 degrees ( The remainder of 820 divided by 360) and 206 degrees (assuming both directions of rotation are set to clockwise). Divide these angle values by 45 and multiply by 45 to obtain the rotation angles of 0 degrees, 0 degrees, 90 degrees, and 180 degrees. Select the relative coordinates of the center of gravity and the value of the rotation angle from the candidate value set of the relative coordinates of the center of gravity and the candidate value set of the rotation angle value, and the image block is disturbed according to the selected relative coordinates of the center of gravity and the value of the rotation angle, thereby obtaining the second to-be-verified image.

The second image to be verified specifically includes: information of the image block, information of a parent image of the image block, and information of a verification method. Wherein, the parent image of the image block refers to the image from which the image block originates. The information of the image block includes the shape and size of the image block, the relative coordinates of the center of gravity of the image block, and the value of the rotation angle.

The second verification rule is used to describe the method of verifying the second image to be verified, such as "rotate the angle of the image block and move the position of the image block to restore the original image".

The verification information of the second verification code is the original position information and rotation angle of the image block. The original position information of the image block can be obtained when the image block is divided from the parent image. Combined with the position offset returned by the client and the relative coordinates of the center of gravity when the image block is scrambled, it can be determined that the scrambled image block is at Whether the verified location information of the user is consistent with the original location information. In particular, the rotation angle in the verification information of the second verification code may also be replaced by the number of image block rotation clicks. Since in the second type of verification code, the candidate value of the rotation angle is fixed, the image block will be rotated by a fixed angle (such as 45 degrees) every time the user operates (such as a click operation) during verification, so the image block can be rotated Clicks instead of rotations. When the verification code verification information includes the number of image block rotation clicks, the number of image block clicks modulo 8 (assuming a rotation of 45 degrees, then 360/45=8) when the user performs the verification operation is taken as a remainder, and the obtained result Compared with the number of image block rotation clicks stored in the verification code verification information, if the two are consistent, the verification is successful.

When generating the third verification code information and the third verification code verification information, it is also necessary to segment the image block from the original image, then generate a random number sequence, adjust the rotation angle of the image block according to the random number in the random number sequence, and generate the third The image to be verified. At the same time, the second verification code verification information can be obtained according to the rotation angle of the image block.

Specifically:

When generating a random number sequence, refer to the description in the generation process of the first verification code information and the first verification code verification information, and generate random numbers according to the system time and the client that initiates the verification code request, such as 038206. Then, based on 360 degrees, the rotation angle of each image block after being scrambled can be obtained according to the value of the randomization seed. For example, in the previous example, the generated three-digit seed sequence includes: 038, 382, 820, 206. According to these three-digit seed sequences, the rotation angles of image blocks after being disrupted are 38 degrees, 22 degrees (remainder of dividing 382 by 360), 100 degrees (remainder of dividing 820 by 360) and 206 degrees (assuming rotation direction is set to clockwise). The image block is scrambled according to the selected rotation angle value, so as to obtain the third image to be verified.

The third image to be verified specifically includes: image block information, image block parent image information, and verification mode information. Wherein, the parent image of the image block refers to the image from which the image block originates. The information of the image block includes the shape and size of the image block, and the rotation angle value of the image block.

The third verification rule is used to describe the way of verifying the third image to be verified, such as "rotate the angle of the image block to restore the original image".

The verification information of the third verification code is the rotation angle, and the size and direction of the rotation angle are related to the size and direction of the rotation angle after the image block is scrambled. For example, the rotation angles of image blocks after they are scrambled are 38 degrees, 22 degrees, 100 degrees and 206 degrees (assuming that the rotation directions are all set to clockwise), then the verification code check information is 38 degrees, 22 degrees counterclockwise. degrees, 100 degrees and 206 degrees, or 322 degrees, 338 degrees, 260 degrees and 154 degrees clockwise.

It can be seen from the description of this step that the determination of the verification code type is related to many factors, even if it is the same terminal device and the same operator, the verification code type may change due to different specific operation behaviors. This increases the security of authentication.

Step 502: Send the verification code information to the client, so that the client displays the verification code information.

Step 503: Receive the verification result returned by the client, compare the verification result with the verification code verification information, and complete the verification.

In the previous steps, the specific verification code type is determined according to the risk level of the user's operating environment. In this step, the verification can be completed by comparing the verification result with the verification information of the corresponding type of verification code.

The verification code verification method provided by the embodiment of the present invention provides the ability to generate multiple verification codes, and can select a verification code corresponding to the complexity according to the risk level of the user operation scene, which improves the network security.

Based on any of the above-mentioned embodiments, in the embodiment of the present invention, the verification code verification method further includes:

The user behavior is obtained according to the analysis of the received user information, and the risk assessment is performed on the user behavior to obtain the risk level of the user's operating environment.

In this embodiment of the present invention, user information refers to information related to user login, such as user geographic location, last login time, terminal device information, cookies, request time, number of requests, etc. According to these user information, user behavior can be analyzed. For example, assuming that the usage scenario of the verification code is login, then based on the aforementioned user information, it can be analyzed such as remote login, login after Token expires (no login for a long time), frequent login (login and logout), etc. Log in again) and other behaviors. User information can be collected by the client and sent to the server.

In the embodiment of the present invention, analyzing user behavior according to user information may be implemented using methods known to those skilled in the art. For example, compare the user's geographic location at the time of this user's login attempt with the saved user's geographic location at the previous user's login attempt, and if the geographic location changes in a long distance (such as in a different administrative region, or the distance changes more than A threshold (such as 50km)), then it can be considered that a remote login has occurred. For another example, combined with the request time and the number of requests, frequent login (login, logout, and login) behaviors can be analyzed.

After the user behavior is obtained, the risk level of the user operation scenario can be evaluated according to the user behavior. For example, logging in after the token expires (not logging in for a long time) is a common user login behavior, and the risk of this type of user login scenario is low risk; remote login occurs relatively infrequently in daily life, and once such user behavior is detected, it can be considered The risk of the user login scenario is medium risk; the probability of changing terminal equipment or personal information (such as mobile phone number or payment password, etc.) in daily life is the lowest. Once such user behavior is detected, the risk of the user login scenario can be considered as high risk .

The verification code verification method provided by the embodiment of the present invention provides a basis for selecting a verification code of corresponding complexity through risk assessment of the user's operating environment, and improves network security.

Based on any of the above-mentioned embodiments, FIG. 8 is a flow chart of a verification code verification method provided by another embodiment of the present invention. As shown in FIG. 8 , the verification code verification method provided by another embodiment of the present invention is applied to the client. Specifically include the following steps:

Step 801: Send a verification code generation request, so that the server generates verification code information and verification code verification information according to the verification code generation request and the risk assessment result; wherein, the verification code information includes the image to be verified and Verification rules; the image to be verified includes a plurality of image blocks, the plurality of image blocks are obtained by splitting the original image, and the positions of the plurality of image blocks in the original image are adjusted by adjusting the offset angle of the center of gravity Scrambling; the verification rule is used to describe the way of verifying the image to be verified; the verification code check information is used to describe the correct position of the image block in the image to be verified.

Step 802: Display the image to be verified and the verification rule according to the received verification code information, so that the user can perform a verification operation on the image to be verified according to the verification rule;

In the embodiment of the present invention, the images to be verified and the verification rules are displayed by means of drawing. As mentioned above, the image to be verified includes: the information of the image block, the information of the parent image of the image block, and the information of the verification method. When drawing, draw the master image and the image block separately. Since the image block information includes the shape and size information of the image block, as well as information such as the position information of the image block, the angle information of the image block, and the number information of the image block, the generated image to be verified by drawing still remains " state of confusion". As a preferred implementation manner, the center of gravity is used to draw the position of the image block during drawing.

Taking the third image to be verified in the third verification code as an example, establish a coordinate system, and then draw the mother image with reference to the coordinate system; then, for any image block, the image block to be drawn can be determined according to the shape and size information of the image block Shape and size (such as length, width, etc.), the position and relative The angle of the coordinate system from which to draw this image patch.

In the embodiment of the present invention, for the image to be verified (such as the second image to be verified) that overlaps between image blocks or between the image block and the parent image, layer technology can be used when drawing, that is, the image block and the remaining parent image are on separate layers, and those layers support merging. The merged layer no longer supports operations (the layers that can be merged are image blocks with correct positions), and the merged layer is placed at the bottom.

To implement layer merging, it is necessary to rely on image block information, specifically, it needs to rely on expected position information therein. Taking the aforementioned second verification code as an example, the expected position information is the relative coordinates of the expected center of gravity. When the image block is moved to make the center of gravity "equal" to the expected center of gravity, it means that the position of the block is matched correctly. Layers can then be merged with surrounding layers.

After the image block is drawn, it is necessary to set the attributes of the image block according to the verification method information in the image information to be verified. For example, for the image blocks in the first verification code, the attributes of the image blocks are rotation and translation; for the image blocks in the second verification code, the attributes of the image blocks are rotation and translation. For the image block in the third verification code, the attribute of the image block is rotation.

Step 803: Generate a verification result according to the user's verification operation, and send the verification result to the server, so that the server compares the verification result with the verification code verification information to complete the verification.

Users can perform verification operations according to the image to be verified and the verification rules. When the verification operation is completed, operations such as clicking and dragging will be performed on the disturbed image blocks in the image to be verified. Driven by these operations, image blocks will change accordingly. Capturing the information contained in these changes can form the verification result.

In the previous embodiments, the verification process of the first verification code has been described, so it will not be repeated here.

When verifying the second verification code, the user can move the selected image block by dragging horizontally or vertically, and rotate the selected image block by clicking. The number of clicks for image rotation and the position offset of the image block are used as the verification result.

When verifying the third verification code, the user can select the image block to be operated (such as concentric droplet or concentric droplet ring) by clicking, and the selected image block can be rotated by dragging the angle. Once the user stops the drag operation, the client collects the angle rotated by the image block during the rotation operation, and uses the rotation angle information as the verification result.

The verification code verification method provided by the embodiment of the present invention evaluates risks by collecting user information, thereby providing verification codes corresponding to risks, and improving network security.

Based on any of the above embodiments, in another embodiment of the present invention, the verification code verification method provided in the embodiment of the present invention further includes:

Collect and send user information, so that the server can obtain user behavior based on the analysis of the user information, and then perform risk assessment on user behavior to obtain the risk level of the user's operating environment.

In this embodiment of the present invention, user information refers to information related to user login, such as user geographic location, last login time, terminal device information, cookies, request time, number of requests, etc. The user information can be obtained by the client according to the user's operation, or is the information of the client itself, so it can be collected by the client and sent to the server.

The verification code verification method provided by the embodiment of the present invention sends user information to the server, so that the server can perform risk assessment on the user's operating environment, provides a basis for selecting a verification code of corresponding complexity, and improves network security.

Based on any of the above-mentioned embodiments, in another embodiment of the present invention, generating the verification result according to the verification operation of the user further includes:

The verification operation of the user is corrected, and a verification result is generated according to the corrected verification operation.

Generally speaking, the precision of the user's verification operation is not high, and it is inevitable to deviate from the expected position during operations such as rotation angle and moving position. In the embodiment of the present invention, the user's verification operation is corrected on the client side. Through the correction operation, the image block that has a certain deviation from the expected position after the user's verification operation can be adjusted to the expected position.

Compared with the correction process on the server side, the verification code verification method provided by the embodiment of the present invention realizes the correction of the user verification operation on the client side, making the vision more natural, and can avoid wrong judgments during the correction process on the server side, thereby improving verification. Code passing rate.
