Design of E-Invigilation Framework Using Multi-Modal Biometrics

Computer-Based Examination (CBE) is an emerging paradigm for the assessment and measurement of knowledge and capabilities. It relies on computer and its associated technologies to provide solution to some of the problems inherent to human-based approaches to conduct of examinations and invigilation. Such problems include connivance, impersonation, external sourcing and peeking. This paper presents the design of a fingerprint, iris and voice-based framework for promoting the security and reliability of CBE. The proposed framework comprises of modules for CBE, e-invigilation and control. The CBE module module comprises of a network backbone, a server and several workstations. The e-invigilation module is designed to use high definition and resolution iris scanners such as IrisShield-USB MK and CMITech BMT series to capture the iris image of the candidates for processing as well as voice recording and processing devices. The control module is designed to handle fingerprint-based authentication of examinees, process monitoring and relaying of situation reports.
