Abstract: Cyber security is an important issue to implement. Different types of user authentication methods are used to achieve this goal. It helps to avoid misuse or illegal use of highly sensitive and confidential data. Text and graphical passwords are mainly used for authentication functioning. But due to various pitfalls, they are erroneous for data security. Text passwords are un assured for reasons and graphical are tight secured in comparison but are sensitive to shoulder surfing attacks. Hence by using graphical password system and CAPTCHA technology a new security primitive is proposed. We call it as CAPTCHA as gRaphical Password (CaRP). CaRP is a combination of both a CAPTCHA and a graphical password scheme. In this paper we conduct a encyclopedic analysis of existing CaRP techniques namely ClickText, ClickAnimal and AnimalGrid. We discuss the advantages and disadvantages of each method and point out research direction in this area. We also try to answer “Are CaRP as secured as graphical passwords and text based passwords?” and “Is CaRP protective to relay attack?
