Enhancing the privacy of e-learning systems with alias and anonymity

Abstract

The privacy of e-learning systems has become a big concern. This paper proposes a new approach, which can effectively protect the privacy of e-learning users. We propose to use the alias and anonymity to implement the privacy preservation for e-learning systems. Through the approach, a unique alias represents the real e-learning user to communicate with each other or e-learning users use the anonymity to hide their information. This approach can be very simple and efficient to be implemented in the e-learning system by well designed meta-formats of digital identities of four types of e-learning users. The anonymity can be adopted by all e-learning users to keep their privacy.
