Secure Access Control Realization Based on Self-Sovereign Identity for Cloud CDM

Public healthcare has transformed from treatment to preventive care and disease management. The Common Data Model (CDM) provides a standard data structure defined utilize hospitals’ data. Digital identity takes significant role as the body of information about an individual used by computer systems identify establish trust among organizations. CDM research network, composed users handling medical information, several digital identities associated with their activity. A high central authority cost can be reduced Distributed Ledger Technology (DLT). It enables control independently third party. To preserve privacy researchers in clinical studies, secure identification is main concern identifying researcher its agents. do so, they should pose legally verifiable credential cloud CDM. By presenting proof represented capability that user has, each access linked authentication verify. Assurance one’s confirmed asserting claims capability, providing entity This paper describes user-centric claim-based operation model based on use cases handle In this model, credentials are designed presented them SPs provide well-controlled CDM, we build prototype management system.
