Enhancing Computer-based Assessment Security using Biometric Facial Data

Abstract

The advancement in Information and Communication Technology has brought about a great revolution in the way most of our activities are being done in this era. Standard examinations and tests are now being conducted globally using the information technology tools. These examinations/tests are being referred to by several names, some of which are the Computer Based Tests (CBT), Computer Based Assessment (CBA), e-examinations, e-assessment and so on. The assessments carried out with these technologies have had its own several challenges in form of examination malpractices most especially impersonation. This paper presents a Computer Based Assessment system which uses biometric facial data capturing of students/candidates for assessment as a measure of preventing impersonation. The system was implemented on Visual Basic.Net platform, tested with a set of students in HND II Computer Science department of the Federal Polytechnic, Bida and the system was able to record zero percent impersonation among the selected students.

Implementing fingerprint authentication in computer-based tests

“…Alarape et al [6] study implemented a computerbased assessment security system using biometric facial data. The system was tested at Federal Polytechnic, Bida with some selected students.…”

“…The study proposed fingerprint authentication against facial recognition of Ref. [6] because identical twins may pass facial authentication.…”
