Trust in eAssessment is an important factor for improving the quality of
online-education. A comprehensive model for trust based authentication for
eAssessment is being developed and tested within the score of the EU H2020
project TeSLA. The use of biometric verification technologies to authenticate
the identity and authorship claims of individual students in online-education
scenarios is a significant component of TeSLA. Technical Univerity of Sofia
(TUS) Bulgaria, a member of TeSLA consortium, participates in large-scale pilot
tests of the TeSLA system. The results of questionnaires to students and
teachers involved in the TUS pilot tests are analyzed and summarized in this
work. We also describe the TeSLA authentication and fraud-detection instruments
and their role for enhancing trust in eAssessment.
