Healthcare Professionals Credential Verification Model Using Blockchain-Based Self-sovereign Identity

Part of the Lecture Notes in Networks and Systems book series (LNNS,volume 618)


In terms of healthcare, fundamental trust and reliability depend on health professionals. But there are several records of doctors practicing with forged licenses worldwide which derogate the impression, reduce trust, and put patients’ lives at stake. Professionals need to verify their identity to ensure that they are licensed to do medical practices. Also, they have to share their personal information credulously to verify their certificates to the hospital they are intended to do medical practices, or to the medical college to pursue higher degrees which are not secure enough as there lies the biggest threat of misusing their personal information. To overcome these two major problems, a system is required that will authenticate a healthcare professional’s digital credentials with minimal identity reveal. In this research work, we propose a privacy-preserving Self-Sovereign Identity (SSI) model leveraging a decentralized Blockchain which verifies healthcare professionals’ credentials to impede them from practicing with fraudulent licenses, disclosing minimal information, and providing data secrecy which proves an attribute from a credential without disclosing the actual value and provides a secured end-to-end communication channel for data transmission.
