of computer systems for the purpose of sharing resources in grid is increasing
on the daily bases. 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- based
cryptographic model to secure grid resources. This paper examines and analyses
existing efforts to tackle these challenges. It also examines Grid Architecture
where various components of a grid play major role in resource sharing and
securing of grid. Biometric-based model was proposed that provides security for
grid users using fingerprint for authentication and authorization in grid due
to its ease of collectability.
