Blind Signatures Based Secured E-Healthcare System

The E-Health cloud paradigm has evolved from the exchange and enhanced sharing of valuable information between various medical institutions, hospital systems and respective care providers. The aim of this system is to reduce the cost and making of efficient process. Preserving privacy of the health record and identity of a patient is one of the prominent concern of the cloud based paradigm. Major bottleneck for a wider reach to potential usages of the cloud is the fear of privacy loss. Patients may not trust the provider of the services and may hesitate to disclose their identities. One of the possible solution is to uphold their anonymity and securely clear their queries. Keeping the aforementioned points in to consideration, in this study, we propose an approach to preserve the identity. In addition to this, the proposed scheme holds the privacy of the patients using a flexible and adaptive approach in the paradigm through an authentication scheme that meets anonymity.
