Cryptographic Health Identity

Own your
health data.

HashCare gives you a cryptographic identity for your health records. Share what you want. Revoke what you don't. Get paid when your data trains AI.

Generate Your Health Hash

This hash represents your identity snapshot. It changes only when you update your data. Anchored to Cloudflare R2 with 7-year retention. Toggle a source above and click Generate Hash to see it change.

Four steps to data sovereignty

No middlemen. No hospital logins. Just cryptographic proof that your health identity belongs to you.

01
Connect your data sources
Link your EHR (Epic, Cerner, athenahealth), Apple Health, wearables (Garmin, Oura, Whoop), or enter manually. We read via FHIR R4.
02
Generate your immutable identity
HashCare produces a SHA-256 digest of your health record snapshot. Timestamp-anchored. Tamper-evident. Unique to you at that moment in time.
03
Create selective disclosure tokens
Your surgeon sees ortho data. Your trainer sees fitness data. Your insurer sees nothing unless you consent. Time-limited. Purpose-specific. Revocable instantly.
04
Earn from your data
Opt into condition-specific Health DAOs. Your anonymized data trains AI models. Revenue shares back to you. Not the hospital. Not the insurer. You.

Your data. Your pool. Your earnings.

Opt into condition-specific data cooperatives. The more your data contributes, the more you earn when it trains the next generation of diagnostic AI.

Your data could unlock trials.

HashCare matches your de-identified health profile against open clinical studies. You decide whether to share. Researchers pay in health credits redeemable across the SolvingHealth ecosystem.

Your hash profile — demo snapshot 3 matched trials

Based on your hash profile: 3 open trials match your knee data.

Share a de-identified segment of your musculoskeletal and vitals data with credentialed researchers. Your identity is never exposed — only the hash-verified data slice you approve.

The health identity layer your app has been waiting for.

HashCare SDK handles cryptographic key management, FHIR R4 data ingestion, consent token lifecycle, and DAO revenue distribution — so you can focus on building features, not compliance infrastructure.

Three lines to generate a health identity. One call to create a time-limited consent token. A standard webhook when a token is revoked.

hashcare-sdk.js
// Connect to HashCare SDK
const hashcare = new HashCare({
  apiKey: 'hc_...'
});

// Generate health identity
const identity = await hashcare
  .generateHash({
    sources: ['apple_health', 'epic_fhir'],
    includeModules: [
      'vitals',
      'diagnoses',
      'medications'
    ]
  });

// Create consent token
// (24hr, read-only, ortho data only)
const token = await hashcare
  .createConsentToken({
    purpose: 'pre-surgical-review',
    expires: '24h',
    scope: [
      'diagnoses.musculoskeletal',
      'vitals.weight_height'
    ]
  });

HashCare is the trust layer.

Every attestation, care record, and identity claim in the SolvingHealth ecosystem is anchored to a HashCare identity. Cryptographic provenance from the first data point to the last.
