Authentication is the process of allowing an authorized user to access a computer system. The commonly used system of authentication is the traditional Text passwordbased authentication mechanism. Though the traditional alphanumeric driven text password entry system is well known for its higher state of security, it even experiences some drawbacks. To replace the traditional schemes and overcome their shortcomings, alternative solutions like graphical password schemes have been introduced. The graphical password systems are less prone to dictionary attacks and are easy to use visually. However, these graphical password schemes suffer from a potential drawback of being more vulnerable to shoulder surfing attacks when compared to conventional text driven passwords. In this paper, we propose a text-graphic password entry system which protects the user�s password from being observed by attackers and prone to shoulder surfing and spyware attacks.
