Secure environments protect their resources against unauthorized access by enforcing access control mechanisms.
So when increasing security is an issue text based passwords are not enough to counter such problems. The need for
something more secure along with being user friendly is required. This is where Image Based Authentication (IBA) comes
into play. This helps to eliminate tempest attack, shoulder attack, Brute-force attack. Using the instant messaging service
available in internet, user will obtain the One Time Password (OTP) after image authentication. This OTP then can be used
by user to access their personal accounts. The image based authentication method relies on the user’s ability to recognize
pre-chosen categories from a grid of pictures. This paper integrates Image based authentication and HMAC based one time
password to achieve high level of security in authenticating the user over the internet.
