generating, by the client terminal, a background picture and a foreground picture according to the verification code parameters; and

disposing, the client terminal, the background picture and the foreground picture at different visual focus positions according to a preset depth of field to generate the three-dimensional image; and

displaying, by the client terminal, the three-dimensional image as the verification code.

11. The method of claim 10 , wherein the acquiring the verification code parameters required for generating the verification code comprises:

acquiring, by the client terminal, the verification code parameters from the client terminal locally or a server.

12. The method of claim 10 , wherein the background picture and the foreground picture are at different focus positions.

13. The method of claim 10 , wherein the generating the background picture and the user-recognizable foreground picture according to the verification code parameters comprises:

randomly selecting, by the client terminal, one or more verification code parameters from the acquired verification code parameters required for generating the verification code to serve as verification code parameters for generating the background picture and the foreground picture; and

generating, by the client terminal, the background picture and the foreground picture according to the randomly selected verification code parameters;

a distortion parameter of the text or the image;

a position of the text or the image; and

a color of the text or image.

14. The method of claim 10 , further comprising:

displaying, by the client terminal, the specified visual focus position for prompting a user to recognize the recognizable content from the three-dimensional image.

15. The method of claim 10 , wherein the verification code parameters comprise one or more of the following parameters:

a text;

an image;

a distortion parameter of the text or the image;

a position of the text or the image; and

a color of the text or image.

16. The method of claim 14 , wherein the displaying the prompt to identify the specified visual focus position for the user to recognize the recognizable content from the three-dimensional image comprises:

inserting indication information for indicating the specified visual focus position into the three-dimensional image; and

displaying the indication information.

17. The method of claim 14 , further comprising:

receiving, by the client terminal, another verification code input by a user according to the three-dimensional image;

determining that the received another verification code is consistent with the recognizable content in the three-dimensional image; and

determining that the user passes a verification.

18. An apparatus comprising:

one or more processors; and

one or more memories storing thereon computer-readable instructions that, when executed by the one or more processors, cause the one or more processors to perform acts comprising:

acquiring verification code parameters required for generating a verification code;

using the verification code parameters as an input to a three-dimensional model to generate a three-dimensional image, wherein a recognizable content corresponding to a specified visual focus position of a user is embedded in the three-dimensional image, the using the verification code parameters as the input to the three-dimensional model to generate the three-dimensional image including:

generating a background picture and a foreground picture according to the verification code parameters; and
