A Comprehensive Survey on Various Graphical Password Schemas against Shoulder Surfing Attack

Shreyal Deshmukh ^[2] | Priyanka More ^[2]

Abstract: A massive security primitives depend on hard challenges that can be computationally solved only by mathematical algorithms operations. There are many drawback in alpha numeric passwords that they can be guessed very easily or can be hacked. So recently many researchers have proposed different graphical techniques such as CaRP, CAPTCHA, PCCP etc. This section makes a deep survey over the many existing systems and thereby make a comprehensive evaluation of the existing techniques making us ready to propose a new technique system which eliminate the drawbacks of the previous systems. The paper describe and studies different application oriented graphical systems proposed earlier and tries to find the loopholes to avoid the attacks.
