Method and device for processing verification codes

Abstract

The invention discloses a method for processing verification codes. The method comprises the steps that two sets of verification codes are generated randomly, one set of the verification codes are used as real verification codes, and the other set of the verification codes are used as disturbance verification codes; a verification code picture is generated, wherein the verification code picture comprises the real verification codes and the disturbance verification codes, and the background, expect the verification codes, in the verification code picture is a transparent background; a verification code background picture is acquired, the real verification codes and the verification code background picture are subjected to same hollow-out processing, the verification code picture is placed on the verification code background picture to be merged, and a merged picture is obtained, wherein the hollow-out position of the real verification codes and the hollow-out position of the verification code background picture coincide; the merged picture is displayed on a webpage background, and the webpage background and the real verification codes are the same in color; a moving instruction to the merged picture is monitored, and the merged picture is moved to a visible area according to the moving instruction. The method for processing the verification codes can improve the difficulty for a robot program to identify the verification codes, and the safety of the verification codes is improved.

Description

technical field [0001] The present application relates to the technical field of computer and Internet data processing, and in particular to a verification code processing method and device. Background technique [0002] In the field of computer and Internet data processing technology, a captcha is a public fully automatic program that distinguishes whether a user is a robot program or a human. Captchas are usually composed of lines and irregular characters that users must read and then enter to successfully log in to a website. Because people can easily read the characters in the picture, but if it is a client attack program (ie robot program), it is difficult to identify the verification code by general means. [0003] The function of the verification code can prevent: malicious cracking of passwords, swiping tickets, flooding the forum, and effectively prevent a hacker from continuously attempting to log in to a specific registered user with a specific program brute forc...

AI Technical Summary

Problems solved by technology

[0005] When the verification code technology in the prior art is faced with the above-mentioned robot program, the verification code is easily deciphered by the robot, and the security is low, which leads to the malicious attacker using the robot to perform a large number of repeated operations on the Internet application, resulting in various Internet applications. Paralyzed, ranging from the loss of various virtual resources, so that the interests of service providers and normal users have been violated
