Issues, Threats and Future Trend for GSP
Lip Yee Por, Xin-Le Lim · 2008
Computer security depends largely on passwords to authenticate human users during the process of gaining access to secure systems. However, users have difficulty remembering passwords most of the time if they choose a secure password. This is because secure passwords usually consist of passwords that are long and random. Therefore, they tend to choose short and insecure passwords. The tendency of choosing insecure passwords has led to many security problems. Graphical passwords are an alternative to alpha-numeric passwords in which users only have to click on images in order to authenticate themselves rather than type alpha-numeric strings. The purposes of this paper are to do classification of graphical passwords system (GPS) and identification of future research area for researchers. In this paper, we attempt to identify a number of threats to the networked computer systems, do research on graphical password system (GPS) and analysis on some aspects of GPS; 1) how each GPS algorithm works, 2) the advantages and disadvantages of each GPS algorithm, 3) how each GPS algorithm is able to address solutions to the threats. We highlight a few aspects which needs to be improved for the future new approach of GPS in order to overcome the shortages of the previous GPS methods which have been studied.
