Detailed Description
In order to make the technical solutions better understood by those skilled in the art, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only partial embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that the terms "first," "second," and the like in the description and claims of this application and in the drawings described above are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the application described herein are capable of operation in sequences other than those illustrated or described herein. Furthermore, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, such that a process, method, system, article, or apparatus that comprises a list of steps or elements is not necessarily limited to those steps or elements expressly listed, but may include other steps or elements not expressly listed or inherent to such process, method, article, or apparatus.
For the convenience of better understanding of the embodiments related to the present application, technical terms or partial terms that may be referred to in the present application are now explained:
DES encryption is DES symmetric encryption, which is a relatively conventional encryption method, and the same key is used for encryption operation and decryption operation, and a sender of information and a receiver of information must share the same key (called symmetric key) when transmitting and processing information, which is a symmetric encryption algorithm. DES encryption divides plaintext into fixed byte blocks, encrypts the byte blocks, and finally strings together to form a ciphertext. DES uses a 56-bit key with an additional 8-bit parity bit, resulting in a maximum packet size of 64 bits. This is an iterative block cipher using a technique known as Feistel in which the encrypted text block is divided in half.
RSA encryption is an asymmetric encryption. Decryption can be done without directly passing the key. This ensures the security of the information and avoids the risk of being cracked due to the direct transfer of the key. Is the process of encryption and decryption by a pair of keys, which are respectively called a public key and a private key. In the RAS algorithm, the public key is public, while the private key needs to be kept secret. Both encryption and decryption algorithms are also disclosed. Although the private key is determined by the public key, the private key cannot be calculated from the public key, which is the security of RSA.
In accordance with an embodiment of the present application, there is provided a method embodiment for image verification, it should be noted that the steps illustrated in the flowchart of the drawings may be performed in a computer system such as a set of computer executable instructions and that, although a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different than that described herein.
Fig. 1 is a picture verification method according to an embodiment of the present application, as shown in fig. 1, the method includes the following steps:
step S102, a first coordinate point is randomly generated according to a coordinate area range corresponding to a picture to be verified;
step S104, sending the first coordinate point to the client, and displaying the first coordinate point on a verification interface of the client;
step S106, receiving a second coordinate point returned by the client, wherein the second coordinate point is generated after clicking the position indicated by the first coordinate point in the verification interface of the client;
and step S108, determining that the client passes the verification under the condition that the first coordinate point and the second coordinate point meet the preset conditions.
In the picture verification method, a first coordinate point is randomly generated according to a coordinate area range corresponding to a picture to be verified; sending the first coordinate point to a client, and displaying the first coordinate point on a verification interface of the client; receiving a second coordinate point returned by the client, wherein the second coordinate point is generated after clicking operation is carried out on a position indicated by the first coordinate point in a verification interface of the client; under the condition that the first coordinate point and the second coordinate point are determined to meet the preset conditions, the client is determined to pass verification, and the purpose of completing comparison verification by combining the picture name with the coordinate point and then performing encryption processing is achieved, so that the difficulty of program identification is increased, the pressure of program operation is reduced, and the verification safety is increased to a certain extent. Parameters such as text information, fonts and colors in various pictures are omitted, the technical effect of data space is saved, and the technical problems that background processing of picture verification modes in related technologies is complicated, the pressure of a database is high, the running speed of programs is low and the like are solved.
In some embodiments of the present application, when it is determined that the first coordinate point and the second coordinate point satisfy the preset condition, determining that the client passes the verification may be implemented in the following manner, specifically, performing a rounding operation on the second coordinate point to obtain a rounded second coordinate point; and determining that the client passes the verification under the condition that the rounded second coordinate point is consistent with the first coordinate point. For example, if the position clicked by the user at the client is not an integer, rounding is performed, 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 the first coordinate is (6,6), so that the rounded second coordinate is consistent with the first coordinate, and then the client can be determined to pass the verification.
In some embodiments of the present application, according to the rounding operation, the rounding operation may be implemented by specifically determining the number of digits of the horizontal axis coordinate and the vertical axis coordinate in the second coordinate point after the decimal point; and rounding the numerical value corresponding to the digit after the decimal point to obtain a second coordinate point after the rounding. For example, the rounding of the second coordinate point is to round the decimal part of the horizontal and vertical coordinates, and if the coordinate of the second coordinate point is (7.8,7.9), the rounding operation is performed at this time to obtain a rounded second coordinate point of (8,8).
In some embodiments of the present application, before the first coordinate point is randomly generated according to the coordinate area range corresponding to the picture to be verified, the method may be implemented as follows, specifically, a coordinate system is established with a predetermined position in the picture to be verified as an origin; determining the corresponding coordinate position of each vertex of the picture to be verified in a coordinate system; and generating a coordinate area range according to the coordinate position. For example, the position of the coordinate origin is determined, and the position of the coordinate origin may be at the center of the picture, at four vertices of the picture, or at any other position. The position of the origin of coordinates is different, and the area range of the coordinates is also different, so the position of the origin of coordinates is determined.
In some embodiments of the present application, before sending the first coordinate point to the client, the method may be implemented in the following manner, specifically, determining a first name of the picture to be verified, encrypting the first name and the first coordinate point by using a first type encryption and decryption algorithm, obtaining encrypted first data, and storing the first data in a database.
In some embodiments of the present application, the sending of the first coordinate point to the client may be implemented in a manner that, specifically, a first name of the picture to be verified is encrypted by using a second type encryption and decryption algorithm to obtain a name in a form of a ciphertext; and sending the name in the form of the ciphertext and the first coordinate point to the client.
In some embodiments of the application, the client verification is determined to be passed according to the condition that the first coordinate point and the second coordinate point meet the preset condition, which can be realized by specifically calling a second type encryption and decryption algorithm to decrypt a ciphertext to obtain a plaintext name; calling a first type encryption and decryption algorithm to encrypt the name in the plaintext form and the second coordinate point to obtain encrypted second data; and comparing the second data with the first data stored in the database, and determining that the client side passes the verification under the condition of the second data and the first data.
To facilitate better understanding of the technical solutions of the present application, a description will now be given with reference to a specific embodiment.

(2) The method comprises the steps of obtaining an image randomly to obtain information such as encrypted data and an image name, encrypting the image name by using RSA, then sending the encrypted image name to a client, planning coordinate axes in the image by calculation, displaying coordinate points (x, y) and allowing the client to click and view the coordinate points.
(3) The maximum value and the minimum value of the coordinate points in the picture are obtained, the code randomly generates one coordinate point which belongs to the coordinate axis range of the picture and then sends the coordinate point to the client, and the client finishes verification by clicking the corresponding coordinate point through a mouse.
(4) When the position clicked by the client is in the area range between the coordinate points, if the distance is smaller than 1/2, a smaller coordinate point is taken, if the distance is greater than or equal to 1/2, a larger coordinate point is taken, rounding operation is carried out, and the position clicked by the same standard is on the x axis, the x point is changed, and the y is not changed; the y point changes on the y axis, and x does not change.
(5) Extracting the coordinate point and the picture name of the client, firstly carrying out RSA decryption on the picture name, carrying out DES encryption on the picture name and the coordinate point, carrying out comparison on the encrypted data and the encrypted data information of the picture name and the coordinate point in the step 2, passing verification if the encrypted data and the encrypted data information of the picture name and the coordinate point are consistent, otherwise failing verification, and obtaining the picture again for planning until the picture passes verification.
It is easy to notice that this solution has the following effective effect:
(1) The verification is carried out through coordinate axis positioning, and the method is convenient for establishing a gallery and planning data aiming at the prior art. Through the accuracy of the coordinate points and the diversity of the pictures, the identification difficulty of the program is increased.
(2) The security of the verification code is guaranteed through the encryption and decryption modes, brute force cracking of a machine is prevented, and operation and use of the client side are simplified to a certain extent.
(3) The related technologies mostly extract information in the picture and combine the coordinate points to obtain the range to finish the verification technology.
