DIGITAL PASSWORD SURVEY

Abstract

At present predictable secret word patterns are subjected to eves dropping, dictionary attacks and shoulder surfing, numerous shoulder surfing unchanged graphical password patterns proposed. At the same time, the utmost public techniques used for authentication are textual passwords. A number of graphical password schemes that are planned in past years. A most of user’s used word-based passwords than pure graphical passwords, so we have proposed wordbased graphical password schemes. Undesirably, none of existing schemes are create hybrid digital graphical password scheme. In this paper, we propose an improved mainly textual-based, numerical based shoulder surfing resistant and other attacks like social engineering resistant, eves dropping and dictionary attacks resistant graphical password by using colors. In the predictable scheme, the operator can robustly, simply and efficiently login system and observe the security, usability and resistance to various attack of the designed system.
