Click-based graphical passwords, which involve clicking a set of user-selected points, have been proposed as a usable alternative to text passwords. We conducted two user studies: an initial lab study to revisit these usability claims, explore for the first time the impact on usability of a wide-range of images, and gather information about the points selected by users; and a large-scale field study to examine how click-based graphical passwords work in practice. No such prior field studies have been reported in the literature. We found significant differences in the usability results of the two studies, providing empirical evidence that relying solely on lab studies for security interfaces can be problematic. We also present a first look at whether interference from having multiple graphical passwords affects usability and whether more memorable passwords are necessarily weaker in terms of security.

“…The "PassPoint" system by Wiedenbeck, et al [11] extended Blonder"s idea by eliminating the predefined boundaries and allowing arbitrary images to be used. As a result, a user can click on any place on an image (as opposed to some predefined areas) to create a password.…”

Graphical Password as an OTP

The most common computer authentication method is to use alphanumerical usernames and passwords. This method has been shown to have significant drawbacks. For example, users tend to pick passwords that can be easily guessed. On the other hand, if a password is hard to guess, then it is often hard to remember. To address this problem, some researchers have developed authentication methods that use pictures as passwords known as graphical password. This paper provides additional layer of security to normal textual password by using graphical password for authenticating the user. As graphical passwords are vulnerable to shoulder surfing attack hence one-time generated password is sent to users mobile. Using the instant messaging service available in internet, user will obtain the One Time Password (OTP).The OTP will be the information of the items present in the image to be clicked by the user. The users will authenticate themselves by clicking on various items in the image based on the information sent to them. Additionally, it provides accessibility to visually impaired people.
