Abstract

The present disclosure discloses a CAPTCHA image generation method and apparatus, and a server, relating to the field of computer technologies. According to the present disclosure, first noise points are generated on a CAPTCHA code in some regions of an initial image and second noise points are generated on a background of the image in another region, so that a machine cannot filter out the noise points in a CAPTCHA image by means of some simple algorithms, increasing difficulty in recognizing the CAPTCHA code by the machine, reducing a risk that the CAPTCHA code is cracked by the machine, and having a strong crack-proof capability.
