A Novel Shoulder-Surfing Resistant Graphical Authentication Scheme

In today's fast-paced world of computers, where every information is transforming into digital form, the user authentication has become a major challenge. To ensure the information access to genuine user and keeping the unauthorized users/intruders at bay, some authentication mechanism is required. The most used method of user authentication is the login-password system. In this paper, a novel graphical user authentication scheme has been proposed. This scheme is a hybrid scheme which makes the use of images along with the text password. The proposed scheme does not require any sophisticated hardware and can be used as an extra level of security.
