The same reference numerals in the drawings denote the same or similar parts, and thus repeated descriptions thereof will be omitted. Some of the block diagrams shown in the drawings are functional entities and do not necessarily correspond to physically or logically separate entities.

In this exemplary embodiment, firstly, an identity authentication method based on Chinese characters is provided, which is applied to a server. With reference to shown in Fig. 1, this identity authentication method based on Chinese character can comprise:

Step S101: Obtain the user request information uploaded by the client;

Step S102: when the user request information is a request for login information, send first instruction information to the client, and the client displays a user information confirmation window according to the first instruction information;

Step S103: receiving the user information uploaded by the client, and judging whether the user information is registered user information;

Step S104: When the user information is registered user information, determine password information associated with the user information according to the user information;

Step S105: Send the password information to the client, and the client generates a password unlock window according to the password information;

Step S106: Obtain and determine whether the user unlock information uploaded by the client satisfies a first preset condition, and when the user unlock information satisfies the first preset condition, determine that the user identity authentication is successful;

Wherein, the password unlocking window can display n=k×i Chinese character images, the i is the number of Chinese character images displayed in each round of the password unlocking window, and the i displayed in each round In the Chinese character image, at least one target Chinese character image and at least 2 interference Chinese character images corresponding to the target Chinese character image are included; the k is the number of rounds of the Chinese character image displayed in the password unlocking window, and the k is an integer of 1 or more.

Specifically, in step S101, the client identifies user operations, obtains the user's request information, and sends the user's request information to the server, and the server obtains the user request information uploaded by the client.

In step S102, when the user request information is requesting login information, send first instruction information to the client, and after receiving the first instruction information, the client displays user information confirmation according to the first instruction information window.

In step S103, the user inputs user information in the user confirmation window, such as user name, and the client receives the user information input by the user and then uploads it to the server. After the server receives the user information uploaded by the client, The user information can be compared with the user information stored in the user information database. When the user information does not appear in the user information database, it is judged that the user is an unregistered user. When the user information appears When it is in the user information database, it is determined that the user information is registered user information.

In step S104, when the server determines that the user information is a registered user, it determines password information associated with the user information according to the user information, and specifically the password information may be stored in a server password information database.

In step S105, the server sends the password information to the client, the client generates a password unlock window according to the password information and provides it to the user, and the user performs a password unlock operation on the password unlock window.

In step S106, the client identifies the user's unlocking operation, and sends the user's unlocking information to the server, and the server judges whether the user's unlocking information satisfies the first preset condition. Confirm that the user identity authentication is successful, and send the information that the user has successfully logged in to the client, and the client shows that the user has successfully logged in, and the first preset condition is met, that is, the user can select all target Chinese characters from k rounds image.

Wherein, the password unlocking window can display n=k×i Chinese character images, the i is the number of Chinese character images displayed in each round of the password unlocking window, and the k is the number of Chinese character images displayed in the password unlocking window The number of rounds of Chinese character images, the k is an integer greater than 1, and the i Chinese character images include at least one target Chinese character image and at least two interfering Chinese character images corresponding to the target Chinese character image ; For example, the password set by the user is Chinese characters "one, two, three", and each round of the password unlocking window can display 3*3=9 Chinese character images, which can be that these 9 Chinese character images contain " The target Chinese character image of the three Chinese characters "one, two, three" and two interference Chinese character images corresponding to the three target Chinese character images respectively; The target Chinese character image containing the Chinese character "one", and the remaining 8 are interference Chinese character images corresponding to the target Chinese character image of "one", and then only "two" is contained in the second round of 9 Chinese character images The target Chinese character image of this one Chinese character, the other 8 are the interference Chinese character images corresponding to the target Chinese character image of "two", and then only the Chinese character "three" is included in the third round of 9 Chinese character images The target Chinese character image of , and the remaining 8 are interference Chinese character images corresponding to the target Chinese character image of "three". Of course, the number of Chinese character images that can be displayed in each round of the password unlocking window can be 12, 8, etc., and is not limited to 9. In order to ensure that the same target Chinese character image can only appear once in each round of the password unlocking window, hash processing is required, and the result of hash processing is stored in the server.

Moreover, before sending the password information to the client, the server needs to initialize the Chinese character password entered by the user during registration. After the initialization operation, the user can select the target Chinese character image in the password unlock window to decode. The initialization process can be as follows:

(1) The server selects the Chinese characters set by the user from the Chinese character set, and generates a password to unlock the window to display the number of iterations of Chinese character images and the Chinese character images that need to be displayed in each round. The Chinese character images of each round are combined to generate a Chinese character image set ;

(2) Generate an initial vector, each pixel point on the character on the Chinese character image is represented by 1, and the point without pixels is represented by 0, wherein, the pixel point representing each Chinese character image is converted into a binary value matrix;

(3) Interferon R(x, y) is generated, and the target Chinese character image is processed through the interferon, so that the target Chinese character image is not easy to be recognized or enumerated by the machine. The effect of described interferon is by a certain point (action point) in a row or column of the target Chinese character image being translated and longitudinally shifted several positions, specifically:

Assume that the target Chinese character image matrix is a matrix of three rows and three columns, its rank is 3, the interferon R (1, 2), and the action point is (1, 1), as shown below:

1 0 0

0 1 0

0 0 1

After adding the effect of interferon, the point (1, 1) is 1, moving one bit to the right and two bits down, the following matrix is generated:

0 0 0

0 1 0

0 1 1

(4) For the situation where the point is covered during the movement, the covered pixel value is changed by one bit in the moving direction. Assuming that the Chinese character matrix is a matrix of three rows and three columns, its rank is 3, interferon R (1, 1), and the action point is (1, 1), as shown below:

1 0 0

0 1 0

0 0 1

After the action, the position of point (1,1) will coincide with the position of point (2,2), that is, 1+1=2. At this time, the pixel value of point (2, 2) will affect the color depth, and the color balance is conducive to the final user's identification and convenient verification. Under normal circumstances, it needs to be determined according to the pixel value of the target Chinese character image. For calculation, it can be moved one bit to the right, or one bit down, generally to a position with a smaller value.

(5) For a certain picture, the system can select a more appropriate amount of interferon according to actual needs, and act on different pixel positions respectively. The more interferon, the greater the difference between the resulting picture and the original picture. The interferon set of a picture is V ₁ ={R ₁ (1,1), R ₂ (1,2),...,R ₁ (m,m)}, where m is the rank of the matrix.

(6) For multiple Chinese characters, multiple images need to be involved, and multiple interferons are generated for each image, and the interferon set of multiple images is VS={V ₁ ,V ₂ ,...,V _n } , where n=k×i.

The above-mentioned identity authentication method based on Chinese characters adopts a graphic password based on Chinese characters. On the one hand, it reduces the inertia of user password setting behavior, user input inertia, and system platform to a certain extent in the traditional identity authentication method based on Chinese characters.
