Description

Technical Field

[0001] This invention relates to the field of computer application technology, specifically to a method and apparatus for processing image verification codes based on sliding trajectory recognition. Additionally, it relates to an electronic device and a processor-readable storage medium. Background Technology

[0002] With the rapid development of internet technology, information and network security are receiving increasing attention from users and service providers. Simultaneously, many criminals have exploited computers to brute-force user accounts to steal sensitive information and property. To prevent such activities, internet service providers use image CAPTCHAs. When a user logs in, they must first verify the validity of the image CAPTCHA before manually entering the code, thus determining whether the login is genuine. Existing solutions mainly include: one is to generate a simple image containing verification information and add distracting information, allowing the user to visually identify and input the valid content; another is to generate a sliding CAPTCHA, where the user drags a specific icon in the image to a designated position using the mouse to verify their login behavior.

[0003] Currently, CAPTCHAs are implemented in various ways on the internet, primarily by adding different types of distracting information or increasing user computer behavior (such as dragging an icon to a designated location with a mouse) to increase the difficulty of recognition. However, with technological advancements, these methods can all be automatically recognized by computers through data processing and image processing techniques, making it impossible for internet application providers to determine whether the behavior is genuine.

[0059] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0060] The following is a detailed description of embodiments of the image CAPTCHA processing method based on sliding trajectory recognition described in this invention. For example... Figure 1 As shown, this is one of the flowcharts of the image verification code processing method based on sliding trajectory recognition provided in this embodiment of the invention. The specific implementation process includes the following steps:

[0061] Step 101: Receive the verification code request information sent by the user.

[0062] Step 102: Generate the corresponding original image verification code based on the verification code request information.

[0063] In this embodiment of the invention, after receiving the verification code request information sent by the user, the server can call a preset image algorithm to generate the corresponding original image verification code.

[0064] Step 103: Generate identification information and a solid color background image corresponding to the original image verification code, and return the identification information and the solid color background image to the user terminal.

[0065] In this embodiment of the invention, before generating the identification information corresponding to the original image verification code, the original image verification code needs to be cached in advance. After caching the original image verification code, the identification information corresponding to the original image verification code is generated. The identification information is a unique serial number corresponding to the original image verification code.

[0066] like Figure 4 As shown, the solid color background image can refer to a pure black background image, and no specific limitation is made here.

[0067] Step 104: Obtain the user's first sliding trajectory data on the solid color background image and the corresponding identification information, and obtain the corresponding original image verification code based on the identification information.

[0068] The first sliding trajectory data can refer to either the mouse sliding trajectory data on the solid color background image for the first time, or the touch sliding trajectory data on the solid color background image for the first time, without being specifically limited here.

[0069] In this step, after the server obtains the user's first sliding trajectory data on the solid color background image and the corresponding identification information, it can retrieve the corresponding original image verification code from the cache based on the identification information.

[0070] Step 105: Analyze the first sliding trajectory data using the sliding trajectory recognition model to determine the first sliding trajectory path; perform perspective processing on the verification code pixel content in the area covered by the first sliding trajectory path in the original image verification code, and return the perspective-processed first image verification code to the user terminal.

[0071] In the specific implementation process, if the first image verification code after perspective processing still cannot display all the verification code information, then the second sliding trajectory data of the user on the first image verification code and the corresponding identification information are obtained; the second sliding trajectory data is parsed using the sliding trajectory recognition model to determine the second sliding trajectory path; perspective processing is performed on the verification code pixel content in the area covered by the second sliding trajectory path in the original image verification code; and the perspective-processed second image verification code is returned to the user. In addition, the third sliding trajectory data of the user on the second image verification code and the corresponding identification information can also be obtained, and the sliding trajectory can be parsed using the sliding trajectory recognition model and further processed; these will not be described in detail here.

[0072] like Figure 2As shown, in this embodiment of the invention, the verification process of the image verification code is triggered by the front-end user terminal and generated internally by the back-end system server using a preset image algorithm. The complete original image verification code is cached internally by the system server, and a pure black background image is returned to the user terminal by default. The user slides on the pure black background image using a mouse, touch panel, or touch screen, and the sliding trajectory data is recorded by the user terminal and submitted to the back-end system server. After the server parses the sliding trajectory path using a preset sliding trajectory recognition model (such as a mouse trajectory recognition algorithm model), it returns the verification code pixel content of the area covered by the sliding trajectory path corresponding to the original image verification code to the front-end user terminal for display. In specific implementation, the user terminal can repeatedly slide the mouse, touch panel, or touch screen to interact with the back-end system server multiple times, making the hidden image verification code content more visible, and finally the original image verification code is completely displayed to the user. By using image generation algorithms and human-computer interaction, the difficulty and complexity of user recognition of the verification code are increased, avoiding brute-force computer cracking, thereby protecting the user's personal information and the service security of the Internet provider.

[0073] The following explanation uses a mouse movement trajectory recognition algorithm as an example. The specific algorithm steps include: First, establishing a coordinate system and determining the initial input coordinates based on the mouse cursor; moving the mouse to generate a series of mouse position data; based on proportional sampling, determining whether the sampling result exceeds the maximum value of the image; if not, enlarging the trajectory line and calculating all pixels within a radius of r, centered on the trajectory point; extracting the RGB values ​​of all the above pixels from the original image (original image verification code) to generate the trajectory map, i.e., the movement trajectory path. For details, please refer to... Figure 3 As shown, I will not go into details here.

[0074] In a complete embodiment, the specific steps are as follows: (1) The user initiates a verification code request through the front-end user terminal. The back-end system server calls a preset image algorithm to generate an original image verification code, deserializes the original image verification code and stores it in a cache (such as Redis), and generates a unique serial number of the original image verification code as the basis for reading the original image verification code next time. After the original image verification code is stored, the back-end system server returns the unique serial number of the original image verification code and a pure black background image (such as Redis) to the user terminal. Figure 4(2) After receiving the pure black background image, the front-end user terminal prompts the user to place the mouse on the pure black background image and click the left button to slide. At this time, the user terminal will identify the sliding trajectory of the user's mouse and record the corresponding sliding trajectory data. When the user releases the left mouse button, the user terminal sends a request to the back-end system server again. This request needs to carry the unique serial number of the original image verification code and the sliding trajectory data recorded by the user's sliding behavior. It should be noted that the present invention is not limited to the use of mouse sliding. It can also be implemented by sliding on a touch panel screen or touch screen using a touch device or finger. No specific limitation is made here. (3) After receiving the request sent by the front-end user terminal again, the back-end system server first obtains the corresponding original image verification code from the cache through the unique serial number of the original image verification code carried in the request. Then, it parses the user's sliding trajectory data through the preset sliding trajectory recognition model (i.e., sliding trajectory recognition algorithm, such as mouse sliding trajectory recognition algorithm). Combined with the original image verification code, it performs perspective processing on the verification code content covered by the sliding trajectory path and returns it to the front-end user terminal. The returned content can be as follows. Figure 5 As shown, it can also be as follows Figure 6 or Figure 7 As shown. (4) After receiving the returned content, the front-end user terminal displays the image verification code result to the user. If the partially revealed verification code is insufficient for the user to perceive the specific verification code content (e.g. Figure 5 or Figure 6 As shown in the example, the user can repeat step (2) multiple times. The front-end user sends the sliding trajectory data to the back-end system server each time, and the server processes it and returns it to the front-end user. This process is repeated multiple times until the user can clearly see the specific location of the verification code content, for example... Figure 7 The final original image verification code shown is: X5Tb. (5) After the user has clearly perceived the specific content of the image verification code, they can manually fill in the correct verification code content into the verification code box and submit the verification request. If the input content is consistent with the original image verification code content, a success message will be displayed. Otherwise, a new original image verification code will be generated and the steps (1) to (5) above will be repeated. The details will not be repeated here.

[0075] The image verification code processing method based on sliding trajectory recognition described in this invention increases the difficulty for computers to brute-force crack the image verification code by enhancing the interaction between the user and the system. It accurately identifies the user's sliding trajectory based on the user's operation behavior and sends the corresponding part of the image verification code content multiple times according to the identified sliding trajectory, without requiring the complete image verification code. This increases the difficulty for users to pass the system verification, thereby improving the system's security protection level.
