Computer security depends largely on passwords to authenticate the human user for access to secure systems. Remembering the password they have chosen is a frequent problem for all users. As a result, they tend to choose short and insecure passwords as compared to secure passwords which usually consist of a long mixture of random alphanumeric and non-alphanumeric characters. Thus, the tendency of choosing insecure passwords has brought up many security problems. Graphical password is an alternative to replace alphanumeric password in which users only have to click on the images in order to authenticate themselves rather than typing alphanumeric strings. The main objectives of this paper are to present a classification of graphical passwords system (GPS) and identify its future research area. In this paper, we attempt to identify a number of threats to the networked computer systems, focus on the research of 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. Besides, the paper also concentrates on the design and the implication of a proposed prototype, namely Multi-Grid Background Pass-Go (MGBPG) which is targeted to be its strength and the winning edge over other graphical password systems. The preliminary result and analysis of the proposed prototype is then presented by comparing it on its role in addressing the drawbacks of current existing GPS and several security attacks. Finally, we highlight a few aspects, which need to be improved in the future to overcome the deficiencies of previous GPS methods that have been invented.
