Authentication between user and server has become more and more important in the insecure network. Chen et al’s proposed a user-participating authentication scheme. The CAPTCHA techniques and visual secret sharing is used in their scheme. The scheme can complete mutual authentication and resist certain known attacks. But for password guessing attack and denial-of-service attack, it can not resist. Therefore, an improved scheme to eliminate these weaknesses is proposed in this paper.
