A verification method and device based on a verification code

Abstract

The embodiment of the present application discloses a verification method and device based on a verification code. The method includes: receiving a verification request, and after receiving the verification request, obtaining a pre-generated first character string; wherein, the first character string contains at least one variable character, according to the pre-established variable Correspondence between characters and spare characters, replace part or all of the variable characters with spare characters to obtain a second character string, generate a verification code based on the second character string, and verify the user corresponding to the verification request . Utilizing the embodiments of the present application can increase the accuracy of user identification of verification codes and reduce the time-consuming verification process. At the same time, it increases the difficulty for computer programs to identify verification codes, and can effectively reduce the possibility of computer programs performing illegal operations.

Description

technical field [0001] The present application relates to the field of computer technology, and in particular to a verification code-based verification method and device. Background technique [0002] At present, the verification code (Completely Automated Public Turing test to tell Computers and Humens Apart, CAPTCHA, also known as the fully automatic Turing test to distinguish between computers and humans) has been widely used as a security verification method, wherein the verification code can be Distinguishing whether the operator is a user or an illegal program, the verification code can prevent illegal operations such as: malicious attempts to log in to user accounts, enumerate cracking of user passwords, or use script control to swipe bills and speak. [0003] In the prior art, in order to prevent automatic recognition of verification codes by illegal programs, the display methods adopted by verification codes are becoming more and more complicated and changeable, and...
