[0020] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0021] It should be noted that the terms "first", "second", etc. in the specification and claims of the present application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequential order. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments of the present application described herein can be implemented in a sequence other than those illustrated or described herein. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.

[0022] In order to facilitate better understanding by those skilled in the art of the present application, the following technical terms or some nouns that may be involved in the present application are explained:

[0023] DES encryption refers to DES symmetric encryption, a relatively traditional encryption method. The same key is used for both encryption and decryption. The sender and receiver of information must share this key (called a symmetric key) when transmitting and processing information. It is a symmetric encryption algorithm. DES encryption divides plaintext into fixed byte blocks, encrypts these byte blocks, and then concatenates them to form ciphertext. DES uses a 56-bit key and an additional 8-bit parity bit, resulting in a maximum block size of 64 bits. It is an iterative block cipher that uses a technique called Feistel, in which encrypted text blocks are split in half.

[0024] RSA encryption is a type of asymmetric encryption. It allows decryption without directly transmitting the key. This ensures information security and avoids the risk of compromise associated with direct key transmission. Encryption and decryption are performed using a pair of keys: a public key and a private key. In the RSA algorithm, the public key is public, while the private key is kept secret. Both the encryption and decryption algorithms are public. Although the private key is determined by the public key, it cannot be calculated from the public key. This is the security of RSA.

[0025] According to an embodiment of the present application, an embodiment of a method for image verification is provided. It should be noted that the steps shown in the flowchart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and although a logical order is shown in the flowchart, in some cases, the steps shown or described can be executed in an order different from that shown here.

[0026] Figure 1 This is a picture verification method according to an embodiment of the present application, such as Figure 1 As shown, the method includes the following steps:

[0027] Step S102: randomly generate a first coordinate point according to the coordinate area range corresponding to the image to be verified;

[0028] Step S104: sending the first coordinate point to the client, and displaying the first coordinate point on the verification interface of the client;

[0029] Step S106, receiving a second coordinate point returned by the client, wherein the second coordinate point is a coordinate point generated by clicking the position indicated by the first coordinate point in the verification interface of the client;

[0030] Step S108 : When it is determined that the first coordinate point and the second coordinate point meet the preset conditions, it is determined that the client verification is passed.

[0031] In this image verification method, a first coordinate point is randomly generated according to the coordinate area range corresponding to the image to be verified; the first coordinate point is sent to the client and displayed on the verification interface of the client; a second coordinate point returned by the client is received, wherein the second coordinate point is a coordinate point generated after clicking the position indicated by the first coordinate point in the verification interface of the client; when it is determined that the first coordinate point and the second coordinate point meet the preset conditions, it is determined that the client verification has passed, achieving the purpose of completing the comparison verification by combining the image name with the coordinate point and then encrypting it, thereby increasing the difficulty of the recognition program, reducing the pressure when the program is running, and to a certain extent, increasing the security of the verification. The technical effect of omitting parameters such as text information, fonts, colors, etc. in various images saves data space, thereby solving technical problems in related technologies such as cumbersome background processing of image verification methods, high database pressure, and slow program running speed.

[0032] In some embodiments of the present application, upon determining that the first coordinate point and the second coordinate point satisfy a preset condition, determining that the client verification has passed can be achieved in the following manner: specifically, performing a rounding operation on the second coordinate point to obtain a rounded second coordinate point; and upon the rounded second coordinate point being consistent with the first coordinate point, determining that the client verification has passed. For example, if the position clicked by the user on the client is not an integer, it is rounded off. Assuming that the second coordinate clicked by the user is (6.3, 6.1), then rounding is performed to obtain a rounded second coordinate (6, 6), and at this time the first coordinate is also (6, 6), so the rounded second coordinate point is consistent with the first coordinate point, and then it can be determined that the client verification has passed.

[0033] In some embodiments of the present application, the rounding operation can be implemented as follows: specifically, determining the number of digits after the decimal point of the horizontal and vertical coordinates of the second coordinate point; rounding the values ​​corresponding to the digits after the decimal point to obtain the rounded second coordinate point. For example, rounding the second coordinate point is rounding the decimal part of the horizontal and vertical coordinates. Assuming that the coordinates of the second coordinate point are (7.8, 7.9), then the rounding operation is performed at this time, and the rounded second coordinate point is (8, 8).

[0034] In some embodiments of the present application, before randomly generating the first coordinate point according to the coordinate area range corresponding to the image to be verified, it can be achieved in the following manner: specifically, a coordinate system is established with a predetermined position in the image to be verified as the origin; the coordinate positions corresponding to each vertex of the image to be verified in the coordinate system are determined; and the coordinate area range is generated according to the coordinate positions. For example, the position of the coordinate origin must be determined first. The position of the coordinate origin can be at the center of the image, or at the four vertices of the image, or at any other position. The position of the coordinate origin is different, and the coordinate area range is also different, so the position of the coordinate origin must be determined.

[0035] In some embodiments of the present application, before sending the first coordinate point to the client, it can be achieved in the following way: specifically, determine the first name of the image to be verified, use the first type of encryption and decryption algorithm to encrypt the first name and the first coordinate point, obtain the encrypted first data, and store the first data in the database.

[0036] In some embodiments of the present application, sending the first coordinate point to the client can be achieved in the following manner: specifically, using the second type of encryption and decryption algorithm to encrypt the first name of the image to be verified to obtain a name in ciphertext form; and sending the ciphertext name and the first coordinate point to the client.

[0037] In some embodiments of the present application, determining that the client verification is successful when it is determined that the first coordinate point and the second coordinate point meet the preset conditions can be achieved in the following manner. Specifically, calling the second type of encryption and decryption algorithm to decrypt the ciphertext to obtain the name in plain text; calling the first type of encryption and decryption algorithm to encrypt the plain text name and the second coordinate point to obtain the encrypted second data; comparing the second data with the first data stored in the database, and determining that the client verification is successful when the second data is consistent with the first data.

[0038] In order to facilitate those skilled in the art to better understand the technical solution of the present application, a specific embodiment is now described.

[0039] Figure 2 Schematic diagram of a flow chart for implementing image verification of coordinate axis positioning points according to an embodiment of the present application. Figure 2As shown, the process mainly includes the following steps:

[0040] (1) Create a gallery, mark the image names with universal unique identifiers, and then save them in the database. All image names and corresponding coordinate points are encrypted with DES and stored in the database for comparison and verification.

[0041] (2) Randomly obtain a picture to obtain encrypted data, picture name and other information, encrypt the picture name using RSA and then send it to the client. Through calculation, plan the coordinate axis in the picture and display the coordinate point (x, y) for the client to click to view the coordinate point.

[0042] (3) Obtain the maximum and minimum values ​​of the coordinate points in the image. The code randomly generates a coordinate point within the image coordinate axis range and then sends it to the client. The client completes the verification by clicking the corresponding coordinate point with the mouse.

[0043] (4) When the position clicked by the client is within the area between the coordinate points, if the distance is less than 1 / 2, the smaller coordinate point is taken; if the distance is greater than or equal to 1 / 2, the larger coordinate point is taken, and rounding is performed. The same standard applies: if the position clicked is on the x-axis, the x point changes, but the y point remains unchanged; if the y point changes on the y-axis, the x point remains unchanged.

[0044] (5) The coordinate points and picture names of the client are extracted. The picture names are first decrypted by RSA, and the picture names and coordinate points are encrypted by DES. The encrypted data is compared with the encrypted data information of the picture names and coordinate points in step 2. If they are consistent, the verification is passed. Otherwise, the verification fails. If the verification fails, the picture is obtained again for planning until it passes the verification.

[0045] It is easy to notice that this solution has the following effective effects:

[0046] (1) Verification is performed through coordinate axis positioning. Compared with existing technologies, this patent is more convenient in terms of establishing a library and planning data. The accuracy of coordinate points and the diversity of images increase the recognition difficulty of the program.

[0047] (2) The security of the verification code is guaranteed by encryption and decryption, which prevents brute force cracking by machines and simplifies the operation of the client to a certain extent.

[0048] (3) Most related technologies extract information from images and then combine it with coordinate points to obtain a range to complete the verification technology. The present invention directly uses specific coordinate points to complete the verification, which simplifies the technology and reduces data pressure.
