Maya: Dad, when you were young, did you use a password to login to password your computer? Dad: Yes, I can remember those days… מאיה: כשהיתה צעיר הישתמשתה בסיסמה ? להכנס למחשב שלך . . . אבא: כן, אני זוכר את הזמנים ההם 2007 - Dr. Yair Levy & Michelle Ramim – Chais 2007, Israel – February 20, 2007. 2
Statement of the problem • • E-learning has become a powerful medium for academic institutions Major growth in e-learning in the past decade – 56% of all US colleges offered e-learning courses in 2000– 2001 academic year*. – Over three million students enrolled in elearning courses in the US in 2000 -1*. • Opponents of e-learning argue that the inability to authenticate e-exam takers is one of the major challenges of e-learning * Source: United States Department of Education, National Center of Educational Statistics (NCES) (2005) 2007 - Dr. Yair Levy & Michelle Ramim – Chais 2007, Israel – February 20, 2007. 3
Theoretical Background • • • Unethical conduct in e-learning Unethical conduct during exams Security in e-Learning Biometric Solutions Fingerprint Biometric Solutions 2007 - Dr. Yair Levy & Michelle Ramim – Chais 2007, Israel – February 20, 2007. 4
Unethical Conduct in E-earning • • Unethical conduct - “a major concern” (Kennedy et al. , 2000) Additional mechanisms are necessary to authenticate users’ access in various elearning course activities not just in the initial login (Newton, 2003) Students’ unethical conduct has intensified as a result of the use of technology and the Internet (Pillsbury, 2004) Need to focus not only on plagiarism (Naude & Hörne, 2006) 2007 - Dr. Yair Levy & Michelle Ramim – Chais 2007, Israel – February 20, 2007. 5
Unethical Conduct During Exams • Cheating on exams has been reported at an alarming range of 74% (Center for Academic Integrity, 2005) • Students’ unethical conduct related to exam taking perceived by faculty to be one of the most serious unethical behaviors (Pincus & Schmelkin, 2003) 2007 - Dr. Yair Levy & Michelle Ramim – Chais 2007, Israel – February 20, 2007. 6
Security in E-Learning • • • Yu and Tsao (2003) discussed security challenges of e-learning environments Huang et al. (2004) discussed aspects of security in e-learning systems and suggested ways to secure e-learning systems. Ramim and Levy (2006) – a case study (JCIT) of a small academic institution faced a cyber attach to their e-learning environment by an insider intruder. 2007 - Dr. Yair Levy & Michelle Ramim – Chais 2007, Israel – February 20, 2007. 7
Biometric Solutions • Biometric is defined as “the application of computational methods to biological features, especially with regard to the study of unique biological characteristics of humans” (Tabitha, et al. , 2006, p. 3) • Unique characteristics: – – • Physiological biometric: retinal and iris, fingerprints, facial images, hand prints, DNA, etc. Behavioral biometric: voice, key board typing, attitude Major popularity growth of biometric solutions, especially after 9/11 2007 - Dr. Yair Levy & Michelle Ramim – Chais 2007, Israel – February 20, 2007. 8
Biometric Solutions (Cont. ) • • • Usability aspect of biometrics authentication systems is “a tradeoff between usability, memorability and security” (Coventry et al. , 2003, p. 153). Traditional password & PINs authentication methods are regularly increasing their length – difficult to remember! Fingerprints systems are currently used in the Disney® parks, financial industry, U. S. immigration services, etc. 2007 - Dr. Yair Levy & Michelle Ramim – Chais 2007, Israel – February 20, 2007. 9
Fingerprint Biometric Solutions • Price of biometric devices is falling in the past decade (Pons, 2006) • Increase reliability – false rejection rate that is only 0. 01%, or 1 out of 100, 000 cases Jay.

The Proposed Theoretical Framework 2007 - Dr. Yair Levy & Michelle Ramim – Chais 2007, Israel – February 20, 2007. 13
Propositions Proposition 1: Students taking e-exams using the fingerprints biometric solution will have lower grades on the e-exam than their counterparts. Proposition 2: Students taking e-exams using the fingerprints biometric solution will take longer time to complete their e-exam than their counterparts. 2007 - Dr. Yair Levy & Michelle Ramim – Chais 2007, Israel – February 20, 2007. 14
Some Observed Limitations • • • In a remote setting, students may ask to have a subject matter expert seat next to them while they take the exam The costs associated with implementing such study in an experimental basis, let alone in a large scale e-learning program Individual perceptions on the use of biometric systems may prevent consent to take part of the study, hence, limit data collection 2007 - Dr. Yair Levy & Michelle Ramim – Chais 2007, Israel – February 20, 2007. 15
