Secure online examination by using graphical own image password scheme

摘要

Nowadays exams are conducted through online so to provide more security, this paper proposed self image password scheme for online examination system which replaces the still digital images. These still images are having major threats and easily hacked by hackers. For that, the online examination system requires new methods to improve the security level and eliminate the threats. This paper implemented new security system by using self image as a password called graphical password with personalized physical tokens in the form of digital pictures which captured from live video. Users selects the positions on the displayed picture, extremely distinguishing optical features are cropped and mined from images. The extracted image is used as a password. New graphical password scheme can be applicable to various real time applications. One such illustration is done in online examination system. This algorithm ensured high-level feasibility studies by examining consistency, integrality, and protection against attackers. The New graphical password scheme is resistance to any kind of attacks. These results indicate that new graphical password scheme demonstrated the results which promise for high level security features while conducting examination.
