M. Tech. (Department of Information Technology, Faculty of Applied and Computer Sciences), Vaal University of Technology. / Computer based assessments have become one of the largest growing sectors in both nonacademic and academic establishments. Successful computer based assessments require security against impersonation and fraud and many researchers have proposed the use of Biometric technologies to overcome this issue. Biometric technologies are defined as a computerised method of authenticating an individual (character) based on behavioural and physiological characteristic features. Basic biometric based computer based assessment systems are prone to security threats in the form of fraud and impersonations. In a bid to combat these security problems, keystroke dynamic technique and facial biometric recognition was introduced into the computer based assessment biometric system so as to enhance the authentication ability of the computer based assessment system. The keystroke dynamic technique was measured using latency and pressure while the facial biometrics was measured using principal component analysis (PCA). Experimental performance was carried out quantitatively using MATLAB for simulation and Excel application package for data analysis. System performance was measured using the following evaluation schemes: False Acceptance Rate (FAR), False Rejection Rate (FRR), Equal Error Rate (EER) and Accuracy (AC), for a comparison between the biometric computer based assessment system with and without the keystroke and face recognition alongside other biometric computer based assessment techniques proposed in the literature. Successful implementation of the proposed technique would improve computer based assessment’s reliability, efficiency and effectiveness and if deployed into the society would improve authentication and security whilst reducing fraud and impersonation in our society.

Résumé Le cadre théorique de la contingence structurelle associe généralement « contexte, structure et performance » (Burns et Stalker, 1961; Woodward, 1965; Lawrence et Lorsch, 1967 ; Mintzberg, 1979).Le besoin de tester cette théorie dans l’environnement d’un pays sous développé (PSD) nous a conduit, dans cette recherche, à l’utilisation d’un cadre réduit basé uniquement sur des liens entre la technologie (remplacée par TI) et la structure (Galbraith, 1972 ; Lacrampe, 1974 ; Leifer, 1988). Notre cadre théorique s’appuie sur les approches managériales, économiques et organisationnelles des TI et de l’EDI (Leavitt, 1968 ; Scott Morton, 1991). Il utilise la théorie contingente de la gestion comptable (Otley, 1980; Chapman, 1997) et des systèmes d’information comptable AIS (Sutton, 1995; Maudlin et Ruchala, 1999; Baldwin et alii, 2000; Dunk, 2001) comme domaine d’opérationnalisation (système d’information fonctionnel). Ce travail commence par la constitution d’une boîte à outils contenant toutes les notions de base à utiliser (théories organisationnelles, TI - technologies de l'information, réseaux informatiques et EDI – échange des données informatisées), conformément aux principes fondateurs du MIS basés sur trois disciplines : Computer, Management et Organization Sciences (Culman et Swanson, 1986). La grille de lecture de la littérature est inspirée par la taxonomie de Urbaczenski, Jessup and Wheeler (2002) qui propose quatre catégories de recherche : économique, organisationnelle, technique et autre. Cette revue de la littérature permettra de proposer un modèle de recherche d’impact des TI et de l’EDI basé sur le cadre de référence structuro - fonctionnaliste et élaboré selon les principes de la théorie des systèmes. Le modèle de recherche utilise une structure causale conçue suivant l’impératif technologique (Markus et Robey, 1988). Il vise à expliquer l'impact organisationnel des TI à travers la stratégie (Porter et Millar, 1985; Wiseman, 1985 ; Palvia, Palvia et Zigli, 1990) sur la conception des MIS / AIS et des structures organisationnelles dans les entreprises d’un pays sous développé (PSD). Ce modèle d’impact organisationnel teste les hypothèses proposées, à partir des données d’une observation longitudinale (1970 à 2002) de quatorze (14) entreprises de la République Démocratique du Congo. Les entreprises échantillonnées de façon non probabiliste en deux catégories sont observées à travers l'introduction de l'EDI dans le système d’information comptable. Les tests de structure des données et de fonctionnement du modèle établissent l’impact des TI sur les structures organisationnelles et parfois sur les systèmes d’information, mais avec des nuances d’atténuation et de contribution suivant la nature de l’environnement ou l’usage de la stratégie. La conclusion de cette étude propose un processus d’apprentissage aux managers congolais pour éviter les dysfonctionnements organisationnels lors de l’adoption d’une nouvelle TI. Elle pose aussi le problème de validité des structures causales utilisées dans les recherches pour analyser l’impact organisationnel des TI. Abstract EDI adoption’s analysis in Congolese firms : an organizational structure impact of IT This research aims to identify the impact of IT (information technology) on organizational structure transformation in the firms of an under developed country. The framework of the contingency theory generally associates "context, structure and performance" (Burns and Stalker, 1961; Woodward, 1965; Lawrence and Lorsch, 1967; Mintzberg, 1979). The model of impact of TI and EDI suggested by this research uses a reduced framework only based on links between technology (replaced by IT) and structure (Galbraith, 1972; Lacrampe, 1974; Leifer, 1988). Based on the original paradigm of MIS, our theoretical framework uses managerial, economic and organizational approaches of IT and EDI (Leavitt, 1968; Scott Morton, 1991). It uses the contingent theory of accounting management (Otley, 1980; Chapman, 1997) and of accounting information systems (AIS - Sutton, 1995; Maudlin and Ruchala, 1999; Baldwin and alii, 2000; Dunk, 2001) as empirical field (functional information system). This workshop begins with the constitution of a toolbox containing all basic concepts to use (organization theories, IT - information technologies, computer networks and EDI – electronic data interchange), in accordance with the original MIS paradigm founded on three disciplines: Computer, Management and Organization Sciences (Culman and Swanson, 1986, p. 298). Then, we draw a theoretical framework of analysis which begins with a literature review inspired by Urbaczenski, Jessup and Wheeler’s taxonomy (2002). This literature review will allow to proposing a research model of IT and EDI designed according to the functionalist framework and system theory principles. The model of research uses a causal structure conceived according to the technological imperative (Markus and Robey, 1988). It aims at explaining the organizational impact of IT through the strategy (Porter and Millar, 1985; Wiseman, 1985; Palvia, Palvia and Zigli, 1990) on the design of MIS / AIS and the organizational structures in the companies of an under developed country (UDC). This study tests the hypotheses of the organizational impact‘s model suggested, basing from the data of a longitudinal observation (1970 to 2002) of fourteen (14) Congolese firms. The companies sampled by convenience in two layers are observed through the introduction of EDI into the accounting information system. The tests of data structure and of operating model performed on the introduction of accounting EDI, confirm the impact of IT on the organizational structures and sometimes on the information systems - IS. That with nuances of attenuation and contribution according to the nature of the environment or the use of the strategy. The conclusion of this study proposes a process of training to the congolese managers to avoid the organizational dysfunctions during the adoption of new IT. It poses also the problem of validity of the causal structures used in research to analyze the organizational impact of IT.
