摘要：Nowadays, all academic institutions exhibit and distribute their material over Internet.
Moreover, e-learning and e-evaluation products is one of the most rapidly expanding areas
of education and training, with nearly 30% of U.S. college and university students now taking
at least one online course. However, Internet increases the vulnerability of digital educational
content exploitation since it is a potential hostile environment for secure data management. The
challenge is that providing current online educational tools that are accessible by a large number
of users, these educational environments handle data of varying sensitivity thus it is increasingly
important to reason about and enforce information privacy guarantees in the presence of
concurrency. The present paper provides a privacy preserving approach in a concurrent online
educational evaluation system. It introduces a privacy preserving approach for utilizing online
concurrent evaluation of acquired student competencies that handles the increasingly complex issues
of designing, developing and e-competence evaluation systems suitable for educational and
e-learning environments. The proposed architecture for an online competence evaluation system
offers access control and protect users' private data while, it provides concurrent procedures for
evaluating competencies.
