Patient‑Owned Data & Trusted AI: The Blockchain Prescription for Healthcare

Sreejith Kaimal is a Healthcare Blockchain Specialist dedicated to solving healthcare’s most persistent challenges — fragmented patient records, opaque data sharing, and the regulatory tightrope of HIPAA compliance — through decentralized identity and HIPAA‑compliant AI. He architects blockchain‑based solutions that give patients full sovereignty over their health data while enabling secure, auditable, and privacy‑preserving AI analytics for providers, researchers, and insurers.

With deep expertise in healthcare IT standards (FHIR, HL7), decentralized identity frameworks (DID, Verifiable Credentials), and HIPAA Security Rule implementation, Sreejith designs systems where every access to medical data is cryptographically verifiable and consented on‑chain. His work moves beyond theoretical pilots to production‑ready architectures that integrate with existing EHR systems and comply with stringent U.S. healthcare regulations. He is passionate about the convergence of blockchain and AI, particularly in ensuring that AI models trained on patient data do so with immutable audit trails and without compromising privacy. At UN Blockchain Week he shows how blockchain can finally deliver on the promise of interoperable, patient‑centric healthcare.
