User authentication is the process that is exercised millions of times around the globe by using different techniques and methods. The most prominent way of authentication is alphanumeric password forms that have been used for decades. Authorized access is becoming a challenging issue because of the introduction of modern technologies. One of the most recent technology in the security world is g-RAT which is secure but has it’s own flaws like being vulnerable to shoulder surfing attack,guessing attack and spyware attack. So in order to tackle these vulnerabilities we’re coming up with a solution called hybrid random graphic authentication. As we mentioned above the existing graphical methods are vulnerable to few attacking techniques so here we are introducing a new technique for data security and login authentication where a set of “nearly” identical images will be used with dynamic patterns and instead of traditional 3x3 grid we’re implementing custom shapes which which will contain more combinations than the former which makes it nearly impossible to perform attacks like shoulder surfing or guessing attack. Another most prominent vulnerabilities of graphical passwords is spyware attack where the attacker could simply use RAT attack to screen record/capture or even keylogger/key listener, here with our method we’re implementing a technology to stop third parties to record or listen keys which prevents the attacker from using spyware attack hence our proposed technique offers complete protection from most of the current vulnerabilities to the existing graphical passwords techniques and making it superior than the existing techniques.
