A Decentralized Protocol for Securely Storing and Sharing Health Records

Cloud computing allows for on demand storage and sharing of records with high degree of availability. However, storing a health record in a cloud provider requires trusting it for the record security. By mitigating it, current approaches focus on confidentiality and access control while not properly handling data integrity. This paper presents a protocol that employs attribute-based cryptography and decentralized networks for secure storage and sharing of health records. The solution addresses confidentiality, access control and integrity of records. A proof of concept of the protocol was implemented and load tests were executed in order to demonstrate its practical feasibility.
