Verification method and device based on picture verification code and computer readable storage medium

Abstract

The embodiment of the invention relates to the technical field of image processing, and discloses a verification method and device based on a picture verification code and a computer readable storagemedium. The verification method comprises the following steps: generating and displaying a verification code, wherein the verification code comprises a plurality of verification code pictures respectively representing one number or one letter string, and reasoning rules for reasoning a verification result according to the number or the letter string; wherein each verification code picture comprises a plurality of picture areas arranged according to a position arrangement rule, each picture area represents a number or a letter, and combining the numbers or the letters represented by the pictureareas according to the arrangement rule to obtain a number or a letter string represented by the verification code picture; receiving a verification result input by the user according to the verification code picture and the reasoning rule; and verifying the verification result input by the user. According to the verification method provided by the invention, the complexity and calculation difficulty of the verification code are improved, the verification code is prevented from being identified by a machine, and malicious behaviors such as automatic batch registration are effectively prevented.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of image processing, and in particular to a verification method, device and computer-readable storage medium based on a picture verification code. Background technique [0002] Captcha is a public fully automatic procedure to distinguish whether a user is a computer or a human. The verification code generated by the current technology has many manifestations, such as a random combination of numbers and letters, pictures containing specific text or specific elements, four arithmetic operations that randomly generate two elements, sliding verification codes, etc. The user recognizes the numbers or letters in the verification code and enters the recognized numbers or letters into the designated position to complete the verification. Because these numbers or letters are usually expressed in irregular characters, which cannot be recognized by machines, it can effectively prevent some hacker...

AI Technical Summary

Problems solved by technology

[0003] However, the inventors found that there are at least the following problems in related technologies: the current verification code elements are mostly numbers and letters, and the numbers and letters are usually easy to find the rules, so that the machines can crack the rules and recognize the verification codes, which cannot effectively prevent Malicious behaviors such as automatic batch registration cannot prevent promotion cheating, ticket swiping and activity arbitrage
