To improve the security weaknesses in user authentication system, many biometrics-based user authentication schemes using smart cards have been proposed by the researchers in 2011, proposed an effective biometric-based remote user authentication scheme using smart cards that can provide strong authentication and mutual authentication, while eliminating the security flaws of Li-Hwang's scheme. In this paper, the authors analyze the security of Das's scheme and they have shown that Das's scheme is still insecure against the user impersonation attack, the server masquerading attack, the off-line password guessing attack, the man-in-the-middle attack and the insider attack.
