Abstract

The research of CAPTCHA recognition can discover the security vulnerabilities of CAPTCHA in time. It has great significance in improving the CAPTCHA design method and promoting the design level of CAPTCHA. Text-based CAPTCHA recognition mostly uses the method of characters segmentation and recognition. It is not very ideal for the CAPTCHAs containing colored interference lines, characters adhesion, rotation, distortion and scaling interference. A kind of de-noising and segmentation algorithm which is suited to the CAPTCHA with colored interference lines is presented in this paper. Finally, it is verified through a large number of real data.
