Abstract

The invention discloses a verification code generation method and device, and relates to the technical field of computers. A specific embodiment of the method comprises: obtaining a target character set used for generating a verification code; for each character in the target character set, generating a sub-adversarial sample; and combining the sub-adversarial samples corresponding to the characters in the target character set to generate a verification code. According to the embodiment, the security problem existing in the prior art due to the adoption of universal adversarial samples is solved, so that the technical effects of not influencing the readability of the user and improving the security of the verification code can be achieved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for generating verification codes. Background technique [0002] The full name of the verification code is "Completely Automated Public Turing test to tell Computers and Humans Apart" (CAPTCHA), which is a fully automatic Turing test to tell computers and humans apart. The verification code is used to distinguish whether the user is a computer or a human, which can prevent malicious cracking of passwords, malicious registration, repeated refreshing of orders, etc. Captcha designs are generated by computers, but only humans must be able to solve them. The prior art generally uses the following methods to generate verification codes based on text, images, or other forms. [0003] In the course of realizing the present invention, the inventor finds that there are at least the following problems in the prior art: [0004] 1. The generated verification code ma...
