Description

Technical Field

[0001] This application relates to the field of computers, and more specifically, to a graphical verification method, apparatus, non-volatile storage medium, and electronic device. Background Technology

[0002] With the development of the internet, a wave of internet technology has swept across all industries. Numerous user-service programs have emerged. When users use these programs, the client submits data to the program's server. If this process is manually operated, the speed will not be fast, and the server can easily handle it. However, if someone uses a machine to impersonate a human to perform brute-force attacks, allowing the machine to automatically execute various services, the volume of data sent per second becomes incalculable. This not only results in a large amount of spam registration information and massive collection and aggregation of user information, but in severe cases, it could even cripple or destroy the entire program.

[0003] Given the above, CAPTCHAs have become indispensable. However, as machines become increasingly intelligent, simple numeric CAPTCHAs may no longer be immune to being cracked. Programs may use OCR to recognize and read text from images, resulting in modern random numeric CAPTCHAs being often distorted and using various confusing colors. Such CAPTCHAs are readable by humans but difficult for machines to recognize.

[0004] However, simple numeric CAPTCHAs still carry the risk of being cracked, and not all programs are suitable for verifying random numeric CAPTCHAs.

[0005] There is currently no effective solution to the problem of poor security in existing digital CAPTCHAs.

[0026] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0027] It should be noted that the terms "first," "second," etc., in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented in orders other than those illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0028] According to an embodiment of this application, a graphical verification method embodiment is provided. It should be noted that the steps shown in the flowchart in the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions. Furthermore, although a logical order is shown in the flowchart, in some cases, the steps shown or described may be executed in a different order than that shown here.

[0029] Figure 1 This is a flowchart of a graphical verification method according to an embodiment of this application, such as... Figure 1 As shown, the method includes the following steps:

[0030] Step S102: Detect click events within the target closed graphic displayed on the human-computer interaction interface;

[0031] Step S104: Starting from the point where the click event lands on the human-computer interaction interface, generate the target graphic element within the target closed graphic;

[0032] Step S106: Based on the duration of the click event, diffuse the target graphic element within the area where the target closed graphic is located;

[0033] Step S108: If the target graphic element covers the target closed graphic, the graphic verification is confirmed to be successful.

[0034] In this embodiment, a click event is detected within a target closed graphic displayed on the human-computer interaction interface; a target graphic element is generated within the target closed graphic, starting from the point where the click event lands on the human-computer interaction interface; the target graphic element is diffused within the area where the target closed graphic is located according to the duration of the click event; if the target graphic element covers the target closed graphic, the graphic verification is determined to be successful, thus achieving the purpose of security code verification based on graphics. By causing the target graphic element to diffuse through the click event until it covers the target closed graphic, the verification method is not only convenient but also has a good countermeasure against brute-force attacks by machines, thereby achieving the technical effect of improving the security of the verification code and solving the technical problem of poor security of existing digital verification codes.

[0035] In step S102 above, the human-computer interaction interface can be a verification code interface for third-party links, browser logins, or frequent user accesses, used to receive user click events and perform graphical verification.

[0036] In step S102 above, the target closed graphic can be a verification code provided in a graphic format.

[0037] In step S102 above, the click event can be a touch operation performed on a touch terminal or a click operation performed by a mouse on a computer terminal.

[0038] In step S102 above, the states of the click event include: click-triggered state, click-continuous state, and click-terminal state. The click-triggered state indicates the start of the click event and is used to determine the landing point of the click event; the click-continuous state indicates that the click event remains in the triggered state for a period of time; and the click-continuous state indicates the end of the click event.

[0039] In step S104 above, the landing point used to generate the target graphic element can be any position within the area where the target closed graphic is located.

[0040] In step S106 above, the target graphic element can spread according to the duration of the click event. The spread speed is random, but as the duration of the click event increases, the proportion of the target graphic element in the target closed graphic continues to increase.

[0041] As an optional embodiment, detecting click events within a target closed shape displayed on the human-computer interaction interface includes: listening to click events on the human-computer interaction interface; determining whether the landing point of the click event is located within the target closed shape; and if the landing point of the click event is located within the target closed shape, determining that the click event is a click event within the target closed shape.

[0042] In the above embodiments of the present invention, the initial conditions for target closed graphic verification can only be met when the landing point of the click event is located within the target closed graphic. Then, the graphic verification process is executed based on the click event landing point within the target closed graphic, making the manual verification operation more convenient and able to cope with brute-force attacks by machines.

[0043] As an optional embodiment, determining whether the landing point of the click event is located within the target closed shape includes: obtaining the landing point position of the click event, wherein the landing point position is used to represent the position information of the landing point on the human-computer interaction interface; obtaining the graphic position of the target closed shape, wherein the graphic position is used to represent the position information of the outline of the target closed shape on the human-computer interaction interface; and determining whether the landing point position is within the range of the graphic position.

[0044] Optionally, location information can be represented by pixel coordinates on the human-computer interaction interface.

[0045] In the above embodiments of the present invention, when determining whether the landing point of a click event is located within the target closed shape, the landing point position on the human-computer interaction interface and the shape position of the outline of the target closed shape on the human-computer interaction interface can be obtained respectively. Then, based on the position information of the outline of the target closed shape, the closed area indicated by the shape position can be determined. If the position information of the landing point is within the closed area, it means that the landing point is within the range of the shape position; otherwise, the landing point is not within the range of the shape position. This realizes the determination of the relative position between the landing point of the click event and the target closed shape.

[0046] As an optional embodiment, spreading the target graphic element within the area where the target closed graphic is located based on the duration of the click event includes: detecting the duration of the click event; if the click event remains continuous, spreading the target graphic element within the area where the target closed graphic is located based on the duration of the click event; if the click event does not remain continuous, determining whether the target graphic element covers the target closed graphic; if the target graphic element does not cover the target closed graphic, clearing the target graphic element.

[0047] In the above embodiments of the present invention, when the click event remains in a continuous state, the target graphic element can spread within the target closed graphic. If the click event is interrupted during the spreading phase of the target graphic element, the target graphic element is cleared, and the verification starts again from the next click event. This makes the manual verification operation more convenient and can cope with brute-force attacks by machines.

[0048] It should be noted that if the target graphic element has already covered the target closed graphic when the click event is interrupted, it means that the target graphic element has already met the verification conditions of the target closed graphic. Even if the click event is interrupted, it will not affect the subsequent graphic verification.

[0049] Optionally, to determine whether a target graphic element covers a target closed graphic, it can be determined whether the target graphic element covers the outline of the target closed graphic.

[0050] As an optional embodiment, when the target graphic element covers the target closed graphic, determining that the graphic verification is successful includes: obtaining the target identifier of the target closed graphic; querying the target area of ​​the target closed graphic in a preset database based on the target identifier, wherein the preset database stores preset identifiers of multiple preset closed graphics and preset areas corresponding to each preset identifier; verifying whether the element area of ​​the target graphic element matches the target area; and determining that the graphic verification is successful if the element area matches the target area.

[0051] Alternatively, the area can be represented by the number of pixels.

[0052] In the above embodiments of the present invention, each preset closed shape is pre-configured with a corresponding preset identifier, and the correspondence between the preset area of ​​each preset closed shape and the preset identifier is stored in a preset database. When it is determined that the target graphic element covers the target closed shape, the target area of ​​the target closed shape can be queried in the preset database, and it can be determined whether the element area of ​​the target graphic element meets the target area. Then, if the element area meets the target area, the graphic verification is determined to be successful. By comparing the element area of ​​the target graphic element with the target area of ​​the target closed shape, it is possible to accurately determine whether the target graphic element covers the target closed shape.

[0053] As an optional embodiment, determining successful graphic verification when the target graphic element covers the target closed graphic includes: detecting whether the click event is disconnected within a preset time when the target graphic element covers the target closed graphic; and determining successful graphic verification when the click event is disconnected within the preset time.

[0054] In the above embodiments of the present invention, when the target graphic element covers the target closed graphic, it is also necessary to determine whether the click event can be disconnected within a preset time. If the click event fails to disconnect within the preset time, it indicates that the click event is likely a brute-force attack performed by a machine. Therefore, when the target graphic element covers the target closed graphic, detecting whether the click event disconnects within a preset time can make the operation of human verification more convenient and can cope with brute-force attacks by machines.

[0055] Optionally, if the target graphic element covers the target closed graphic, a prompt message can be generated to remind the user to interrupt the click event.

[0056] As an optional embodiment, before detecting click events within the target closed graphic displayed on the human-computer interaction interface, the method further includes: obtaining graphic information of the target closed graphic, wherein the graphic information includes at least: the target area and target identifier of the target closed graphic; displaying the target closed graphic on the human-computer interaction interface based on the target area, and adding a target identifier to the target closed graphic.

[0057] The above embodiments of the present invention can pre-set the graphic information of the target closed graphic, determine the target area and target identifier of the target closed graphic, and then display the target closed graphic according to the target area in the human-computer interaction interface, and add the target identifier to the target closed graphic, thereby realizing the generation of the target closed graphic.

[0058] Optionally, displaying the target closed shape on the human-computer interaction interface based on the target area includes: randomly generating an initial closed shape of arbitrary shape on the human-computer interaction interface; adjusting the size of the initial closed shape according to the target area so that the area of ​​the initial closed shape matches the target area, and then determining that the initial closed shape is the target closed shape.

[0059] The above embodiments of the present invention can randomly generate target closed graphics of any shape based on the target area. The target closed graphics displayed are not limited by shape, and can generate target closed graphics more flexibly. Without changing the difficulty of graphic verification, it can further limit the brute-force cracking behavior of machines.

[0060] This application also provides an optional embodiment, which provides a verification code method based on shadow diffusion overlay graphic verification, which can verify whether it is a human operation and has a good way to deal with malicious access that is not a human operation.

[0061] Figure 2a This is a schematic diagram of a graphical verification method according to an embodiment of this application. Figure 1 , Figure 2b This is a schematic diagram two of a graphical verification method according to an embodiment of this application. Figure 2c This is a schematic diagram of a graphical verification method according to an embodiment of this application. Figure 3 ,like Figure 2a , Figure 2b and Figure 2c As shown, by continuously clicking any point within the target closed shape, a shadow color is applied to the clicked point (i.e., a target graphic element is generated), and this shadow color spreads outwards. When the target closed shape is completely covered from blank space to the shadow color (i.e., the target graphic element), it means the CAPTCHA verification is successful. A pixel background is used here for demonstration, and the covered shape changes color to show full coverage.

[0062] As an optional embodiment, the CAPTCHA method based on shadow diffusion overlay graphic verification is implemented through the following steps:

[0063] S11. The backend will store the pixel size information of the generated canvas into the database (such as the preset database) and record the identifier ID.

[0064] S12. Generate a controllable number of random pixels based on the size of the canvas pixels, and send this number of pixels and its ID to the front end.

[0065] S13. The front-end page (such as the human-computer interaction interface) generates a closed shape (such as the target closed shape) on the canvas based on these points. The number of pixels in the closed shape and the number of pixels in the back-end response can be within 1-2 pixels.

[0066] S14. Obtain the pixel coordinates of the generated graphic lines and listen for user clicks (such as click events) to verify whether the pixel coordinates of the landing point on the canvas (i.e., the landing point position) are within the closed graphic (such as within the range of the target closed graphic's graphic position).

[0067] S15. The front end monitors in real time whether the generated shadow (such as the target graphic element) fully covers the graphic lines (such as the outline of the target closed graphic), and returns the number of pixels within the closed lines, the graphic coverage indicator, and the canvas indicator to the back end.

[0068] S16. The backend first checks whether the graphic lines are fully covered. If they are fully covered, it retrieves the relevant information of the canvas from the database based on the canvas identifier ID, verifies the returned pixels to determine whether the user has successfully verified, and sends the status response to the frontend.

[0069] S17. After obtaining the success status, the front end determines whether the user is still in the click event.

[0070] S18. If the user fails to release the click within the specified time after successful image verification, the verification will fail; otherwise, the verification will succeed.

[0071] As another optional embodiment, the CAPTCHA method based on shadow diffusion overlay graphics verification can also be implemented through the following steps:

[0072] S21. When a user logs in, a graphical verification code (such as a closed target graphic) pops up.

[0073] S22. Prompt the user to click inside the graphic (such as the target closed graphic) until the shadow (such as the target graphic element) spreads and covers the entire graphic (such as the target closed graphic).

[0074] S23. After a user randomly clicks on a graphic (such as a target closed graphic), the shadow at the clicked point (such as a target graphic element) begins to spread.

[0075] S24. When the spread reaches full coverage, a display icon will be shown on the page to remind the user that they can release the click.

[0076] S25. After a series of verifications, the front-end and back-end notify the user that the verification was successful.

[0077] S26. If the user releases the click and the spread is cleared, but the click is not released after full coverage for more than the specified time, the verification fails.

[0078] The verification method provided in this application offers high security. The user's click diffusion position, diffusion rate, and diffusion coverage area are all randomized, greatly increasing the difficulty for machines to crack it. While improving security, it reduces the complexity of user verification, providing a better user experience and demonstrating excellent novelty. The verification success is highly intuitive, not only convenient for users but also providing a good countermeasure against brute-force attacks by machines.

[0079] The technical solution provided in this application verifies user actions by expanding the coverage of the shadow of a graphic (i.e., the target graphic element). It can be displayed and added in scenarios such as redirecting to third-party links, browser login, and frequent user visits. It is not only easy to operate, but also has more room for maneuver in terms of style.
