Novel Method for Graphical Passwords using CAPTCHA

scheme. In this paper we conduct a comprehensive survey of existing CaRP techniques namely ClickText, ClickAnimal and AnimalGrid. We discuss the strengths and limitations of each method and point out research direction in this are a. We also try to answer “Are CaRP as secured as graphical passwords and text based passwords?” and “Is CARP protective to relay attack?"
