Abstract
The most popular user-authentication method is the password. Many authentication systems try to
enhance their security by enforcing a strong password policy, and by using the password as the first
factor, something you know, with the second factor being something you have. However, a strong
password policy and a multi-factor authentication system can make it harder for a user to remember
the password and login in. In this paper a bio-password-based scheme is proposed as a unique authentication
method, which uses biometrics and confidence interval sets to enhance the security of
the log-in process and make it easier as well. The method offers a user-friendly solution for creating
and registering strong passwords without the user having to memorize them. Here we also show the
results of our experiments which demonstrate the efficiency of this method and how it can be used to
protect against a variety of malicious attacks.
