HIPAA-compliant healthcare data exchange
Providers need to move patient records between organizations — and prove, for every disclosure, exactly what was shared and when. DataMgmt Node makes that proof cryptographic.
The challenge
Sharing patient data across providers, labs and payers is unavoidable, but HIPAA requires an accounting of disclosures. Traditional systems put that trail in a database you and your auditors have to trust. If the log can be edited, it is not evidence.
How DataMgmt Node helps
- End-to-end encryption. Records are protected with Fernet (AES-128-CBC) before they ever leave your node.
- Immutable audit trail. Each disclosure is recorded on an EVM chain and can be verified later with
GET /verify_data. - Data sovereignty. Records live on your self-hosted node and the P2P network — no PHI on the chain, and no central cloud custodian.
- Access control. Shares are directed to a specific recipient address, and the plugin system can enforce your own authorization rules.

FAQ
How does DataMgmt Node support HIPAA compliance?
Every disclosure of a patient record is recorded on-chain as an immutable audit event, and the payload is end-to-end encrypted with Fernet. That gives you a verifiable, tamper-proof trail of who shared what and when — the accounting-of-disclosures evidence HIPAA expects — without trusting a third-party log.
Does patient data go on the blockchain?
No. The encrypted record is stored on the P2P network; only an encoded compliance event (a zero-address transaction) is written on-chain. The chain proves the share happened; it never holds PHI.
