Embodiment Construction

[0032] Such as figure 1 As shown, in one embodiment, a method for implementing an image verification code includes the following steps:

[0033] In step S110, the character string is obtained, and the character string is processed according to the character string to obtain the action sequence and position corresponding to the characters in the character string.

[0034] In this embodiment, the content in the image verification code is displayed in the form of a string, which includes but is not limited to numbers, letters, Chinese characters, and mathematical formulas, and can also be preset in the whitelist dictionary in special application scenarios. characters, and avoid some dirty words through the preset blacklist dictionary. The action sequence corresponding to the character in the string will indicate the action corresponding to the character in each frame, and each character has a corresponding action sequence. A sequence of actions corresponding to a character.

Abstract

The invention relates to a method and system for achieving an image verification code. The method comprises the steps of obtaining a character string, performing treatment according to the character string to obtain movement sequences and positions corresponding to characters in the character string; selecting image elements, and obtaining movement tracks corresponding to the image elements according to the positions corresponding to the characters; fusing the character string and the image elements according to the positions corresponding to the characters to obtain and display the image verification code, and performing frame-by-frame playing of the characters and the image elements in the image verification code according to the movement sequences corresponding to the characters and the movement tracks corresponding to the image elements. The system comprises a character processing module, an element processing module, a fusion module and a display module. Crack resistance can be improved through the method and system for achieving the image verification code.

Description

technical field [0001] The invention relates to network security technology, in particular to a method and system for realizing an image verification code. Background technique [0002] In order to reduce network security risks, major websites often distinguish whether the current user is a human user or a machine user by setting a verification code, so as to prevent machine users from deceiving their identity on the website, maliciously cracking passwords, swiping tickets, flooding forums, and swiping pages. . On the website, only by successfully answering the verification questions posed is considered a human user and continues to enjoy the service. [0003] The image verification code implementation scheme commonly used by major websites is to give an image containing a string in the website interface, requiring the user to input a string, and when the input string is consistent with the string in the image, the current user will are treated as human users. [0004] Im...
