Problems solved by technology

Existing verification codes are usually picture verification codes containing text, and the text is displayed in a non-standard form in the picture, which is not easy to be recognized by the machine, so that the malicious operation performed by the machine cannot pass the verification
[0003] However, with the advancement of machine recognition technology, ordinary picture verification codes can be automatically recognized by machines through pattern matching, and the success rate of automatic recognition is high, easy to crack, and there are security risks

Abstract

The invention provides a verification code generating method and device. The verification code generating method includes the steps that at least two image sub-images are acquired by splitting a verification code image to be generated; at least one of the image sub-images is displayed to a user, and the image sub-images are different from the verification code image to be generated when being independently displayed; when preset operation is detected, the display sub-images are combined into one verification code image, and then the verification code image to be generated is acquired. By the adoption of the method, the success rate in which a verification code is automatically recognized by a machine can be reduced.

Description

technical field [0001] The present invention relates to the technical field of verification, in particular to a verification code generation method and device. Background technique [0002] Currently, many websites require users to enter verification codes to prevent cheaters from maliciously using resources through machine operations. Existing verification codes are usually picture verification codes containing text. The text is displayed in a non-standard form in the picture, which is not easy to be recognized by the machine, so that malicious operations performed by the machine cannot pass the verification. [0003] However, with the advancement of machine recognition technology, ordinary picture verification codes can be automatically recognized by machines through pattern matching, and the success rate of automatic recognition is high, which is easy to crack and poses security risks. Contents of the invention [0004] The present invention aims to solve one of the te...
