Abstract

The embodiment of the invention discloses a character verification method and device, computer equipment and a storage medium, and the method comprises the steps: obtaining a to-be-synthesized verification material which comprises a background image and a verification character; inputting the verification material into a preset style conversion model to generate a verification image having the same style as the preset style mode; and reading the verification image output by the style conversion model so as to use the verification image for character verification.The background image and the verification character are converted into the same style images, and then the grain change in the whole verification image is coherent and smooth; and the background image and the verification characterdo not have sharp pixel comparison, so that the difficulty of extracting the verification character through an image processing technology is improved, the confusion degree between the background image and the verification character is further improved, the recognition difficulty and the error rate are increased, and the safety of character verification is effectively guaranteed.

Description

technical field [0001] The embodiment of the present invention relates to the field of data security, in particular to a character verification method, device, computer equipment and storage medium. Background technique [0002] With the development of science and technology, the advent of the information age has brought us a lot of convenience, and at the same time, it has also brought many troubles to people's lives. For example, when online tickets are purchased through the Internet, there are often unscrupulous vendors who quickly swipe tickets by developing applications, and then resell them at high prices to obtain huge profits, but users who really need to buy cannot purchase through the Internet interface, and in real life, similar The robbing of Internet resources occurs in various fields, and it is difficult to eliminate the behavior of quickly swiping tickets and receiving commissions through applications. In order to limit the occurrence of the above-mentioned b...
