Abstract

The present invention provides a method for establishing a verification code generation model. The method for establishing a verification code generation model comprises: acquiring a verification codeof a preset type; acquiring a constraint information set and establishing a correspondence between each constraint information in the constraint information set and each verification code; constructing a generation against network containing a generation model and a discriminant model; and according to the acquired verification code and the constraint information corresponding to the verificationcode, training the generation against network, and using the generation model of the trained generation against network to obtain the verification code generation model. The present invention also provides a method for generating a verification code. The method for generating a verification code comprises: sampling constraint information from a preset constraint information set; and inputting a p-dimensional random variable and the sampled constraint information into a trained verification code generation model, and using an output result of the verification code generation model to obtain the verification code corresponding to the sampled constraint information. According to the technical scheme of the present invention, the steps for generating the verification code can be simplified, and the generation efficiency of the verification code can be improved.

Description

【Technical field】 [0001] The invention relates to the technical field of machine learning, in particular to a method and device for establishing a verification code generation model and generating verification codes. 【Background technique】 [0002] At present, the forms of verification codes mainly include the following types: numbers, letters, Chinese characters, images, and static or dynamic combinations of the above elements. Moreover, the strategies for generating verification codes in existing technologies are roughly similar. Taking image verification code generation as an example, the process can be summarized as follows: define a preset character set; generate a random number, and match the character corresponding to the random number from the preset character set; Repeat the above steps for the length of the generated captcha; create a blank image, draw the image background; draw the generated string into the image to get the captcha. That is to say, the traditiona...
