Resource shared in grid is not limited to files alone but also includes computer resources such as memory, processors, etc. The security challenges resulting from this sharing is enormous including authentication, authorization, integrity, availability. These call for research attentions as evidenced from the reviewed literatures. Several researches have proposed cryptographic approaches as a promising solution to the various security challenges. However, issues surrounding the knowledge-based authentication approach motivate the researchers to be more innovative by proposing biometric- 1 COMSIT Directorate, University of Ilorin, Ilorin, Nigeria.
