An image verification code generation method and system, the method comprising: randomly selecting, from a character set, a set of character strings comprising a plurality of characters, lengths of the character strings being randomly determined (S101); randomly selecting a font from a font set for each character in the character strings, and rendering to obtain rendered characters, the fonts in a font library being a set of size n × m comprising n fonts and m word sizes, and n and m being preset natural numbers (S102); distorting each of the rendered characters to obtain distorted characters (S103); generating an image comprising a plurality of the distorted characters (S104); and generating at least one interference line on the image to obtain an image verification code, a path of the interference line being randomly generated (S105). The method improves user experience of the verification code, increases the difficulty of recognizing the verification code by a computer, and effectively ...
