At CTU FTS we are currently developing BioTest, an authentication system for testing students using state-of-the-art information technology and unambiguous Biometric authentication for each user. We use this system for identification during exams and testing. The BioTest software operates on the basis of a student's face recognition comparing the pattern with data on the student's ID card, while informing...
A technique of online face authentication has been proposed which may be used for the user identification. Pre processing of acquired image has been accomplished through consecutive steps viz. image reading and subsequent adjustment of illumination level and feature extraction from a certain portion of the clipped image to form a template. Provision for automatic uploading of the template through...
Multi-biometrics makes a big progress for the subject of biometrics. Multi-biometrics usually obtains a higher accuracy and reliability than single biometrics. Multi-biometrics depends on a fusion strategy to achieve this. The feature level and matching score level fusion seem to be two widely used and very effective fusion strategies. In this paper, we propose to combine a feature level and matching...
Graphical passwords provide a promising alternative to traditional alphanumeric passwords. They are attractive since people usually remember pictures better than words. In this extended abstract, we propose a simple graphical password authentication system. We describe its operation with some examples, and highlight important aspects of the system.
In this paper we present a solution to obtain useful and reliable user logs in a learning management system (LMS). Current LMS logs are combined with biometric-based logs that show the student behaviour. Our system models the student behaviour, allowing to know exactly how much time the student spends in front of the computer examining the contents of the LMS. Besides, user verification and face tracking...
Despite of the advances in the e-learning domain during the last decades, there is a lack of suitable mechanism to carry out assessment with the appropriate measures to avoid cheating. Current LMSs do not provide the needed features to check that the intended student is taking the online exam by himself, or even to know if he has spent the whole session time in front of the computer. This paper presents...
