Abstract
Security in the computer is largely supported by passwords for authentication process. Alphanumeric passwords still remain as the most common Authentication method. This conventional authentication method has been shown to besusceptible security threats such as phishing attack, brute force attack, dictionary attack, spyware attack etc. To overcome the vulnerabilities of traditional methods, a numerous graphical password authentication systems have been designed. These graphical passwords are usually seen as complex and time consuming. Furthermore, the existing graphical passwords are susceptible to spyware and shoulder surfing attacks. In this paper we propose this 2 step random coloured grid graphical password scheme to abolish the above mentioned well known security threats. Considering the drawbacks of the existing graphical password systems, we have proposed a robust graphical password scheme, which is highly adaptable for traditional desktop systems, smart phones and other web applications
