ABSTRACT
The information has become one of the valuable things that have to be care off on this century and also in the future. Many organizations have to provide high level of security in order to secure the information of their customer especially in banking institution which involves many parties and are usually will be the target of bad people. The function of authentication system is very need to be considered of as it one of the defense to the cyber security threat. Authentication system using graphical one time password is proposed to solve the problem faced by the user. First, user has to create an account by sign up. In the registration interface, the user has to enter the username, email and phone number. This username and email will be used to authorize the user to access the system.

Initially the user will be prompted with the login interface. In this phase the user have to enter the Username as being registered before. Then the system will check the username in the data store. Then the user have to click on the Request AIC button to enable the server send graphical password to the registered email that related to the Username enter by the user on login phase. The user has to check the email to obtain the graphical password. Next, the user has to choose the image on login phase based on image receive on email with correct sequences and specific time. Then, the user has to click on login button to send the login request to the server. The server will compare the password entered by the user with the graphical password send to the user email. If the password is match, then the user will be directed to the homepage. As the increases of information technology the threats that want to steal the information are also increases. The problems that exist which are the purpose for this project being developed are the unauthorized user can crack the login password for authorized user easily, the login process is exposed to the man-in-the-middle attack, and the lack of security in alerting the user about the unauthorized access of the account. In order to propose the solution, the approach used is by using the combination of graphical password as an one time password.

This project is expected to help all users to have highly secure authentication system to secure their information. For the future work, this project is expected to be upgraded into more secure system and user friendly with the usability and the security is in balance that can be used for every people.
