ABSTRACT
Nowadays, we have known that computer security mostly depends on password to verify and authenticate users. There are many authentication schemes proposed and most of them are still have weaknesses. Some of them are based on the physical and behavioral properties of the user such as voice recognition, and some others are based on knowledge of the user such as textual and graphical passwords. However, these schemes are still not secure enough and allow attackers to steal the data easily. Moreover, users often use simple password that attackers can guess easily. Therefore, it needs something for secure and user-friendly authentication schemes to overcome this problem. In this paper, I present 3-level password authentication scheme to overcome the problem. The three different levels used in the 3-level password authentication scheme are text password, pattern-based password and one-time password (OTP). These authentication schemes are classified as knowledge based authentication. The main objective of the three level security system is to provide advanced security to the web applications, to prevent unauthorized access and to make the applications more user friendly. Hopefully, the system can give a better secure environment to the user from unauthorized access.
INTRODUCTION
Authentication is any protocol or process that permits one entity to establish the identity of another entity. Nowadays, we can say password is mostly widely used to verify and authenticate users. For instance, online banking system is important to have high security level to secure users’ accounts and protect their asset as well as their personal datas from malicious hands. One of the method to secure system is by using password. Password is a secret word or phrase created by the user in ensuring unauthorized user cannot access the restricted resource. At the same time, it is well known that there is a tension between the security and usability of passwords. Oftentimes, secure passwords tend to be difficult to memorize (i.e., less usable), whereas passwords that are memorable tend to be predictable. Generally, in order for authentication system to be practical, three level authentication is designed to provide additional security.
There are many schemes that had been proposed but still have their weaknesses. For your information, the three level authentication is the combination of three existing scheme which is text-based password, pattern lock password/graphical and one time password to form a better protection. In this, the traditional method used is text-based password. These type of password are strings of letters and digits. In this technique, the password is usually short and easy to predict that lead to malicious activities easily. Hence, to increase the level of security in a system, three level authentication is proposed.

OBJECTIVES
- To design an implementation of password authentication that give highest security in authenticating users.
- To implement the applications/system that more user friendly.
- To test and evaluate the authentication scheme in preventing unauthorized access.

RESULTS
The most successful event is the one that achieves your goals and exceeds your expectations. " |
CONCLUSIONUsing multifactors authentication would increase the security level of a system to prevent from unauthorized users access the datas.
