Privacy-Preserving Healthcare Records on Blockchain
Verify medical records without exposing patient data. Hash-based blockchain storage ensures privacy and authenticity simultaneously.
Healthcare Verification Challenges
Fake medical certificates and prescriptions are a growing concern
Transferring medical records between hospitals is slow and error-prone
Patient data privacy must be maintained while enabling verification
Insurance fraud through fabricated medical documents costs the industry crores
No standardized system exists for cross-hospital record verification in India
How Setara Solves This
Hash-Only On-Chain
Only the document hash is stored on the blockchain. Actual patient data stays with the hospital — zero exposure risk.
Consent-Based Sharing
Patients share their document hash or QR code to enable verification. No data moves without patient consent.
Cross-Hospital Verification
Any hospital on the Setara network can verify records issued by another. One system for all healthcare providers.
Insurance Fraud Prevention
Insurers verify medical documents against the blockchain before processing claims — no fake certificates.
How It Works
Hospital Registers
The hospital or healthcare provider registers on Setara and gets API credentials.
Record Issuance
When issuing a medical certificate or discharge summary, the hospital hashes it and registers the hash on-chain.
Patient Gets Proof
The patient receives their document plus a verification QR code/link they control.
Third-Party Verifies
Insurers, other hospitals, or employers verify the document hash — confirming it was issued by a registered hospital.
Benefits
Patient Privacy by Design
Zero patient data on the blockchain. Only cryptographic hashes — mathematically impossible to reverse.
Reduce Insurance Fraud
Insurers verify claims documents against blockchain records before payout.
Seamless Hospital Transfers
Patients moving between hospitals carry verifiable proof of their medical history.
Regulatory Compliance
Hash-only storage complies with data protection regulations while enabling verification.
