Executive Summary

Over the years, e-learning and e-examination has become standard in many institutions of higher learning. It has been observed that examination questions and results can be easily intercepted by invalid users, thus the security of resources shared among valid users is not guaranteed.

RBES attempted to solve the security issue by the combination of two authentication techniques: text-based authentication and graphical password authentication.
