Anonymous Authentication Scheme in e-Health Cloud environment
The adoption of an e-Health Cloud has different advantages especially allowing sharing and exchanging information between medical institutions, availability of information, reducing costs, etc. However, preserving identity privacy is a significant challenge of security in all environments, and constitutes particularly a very serious concern in Cloud environments. Indeed, an important barrier to the adoption of Cloud is user fear of privacy loss in the Cloud, particularly in an e-Health Cloud where users are Patients. Users may not want to disclose their identities to the Cloud Service Provider, a way to protect them is making them anonymous. In this paper, we will propose an adaptive and flexible approach to protect the identity privacy of Patients in an e-Health Cloud through an anonymous authentication scheme.
