Patient-sovereign consent infrastructure

Your Life. Your Data.Your Control.

LifeCare.ID^® is the consent layer for intelligent healthcare - cryptographic, revocable permission over your health data, wherever it lives. Built for patients, trusted by physicians, compliant by design.

Zero PHI, ever The key never leaves your device Revoke anything, any time

The guarantee

No health data ever passes through LifeCare.ID^®.

A full compromise of LifeCare.ID^® yields tokens, public keys, and consent metadata - never a single health value. Your data flows directly between where it lives and whatever destination you authorize. Our infrastructure touches only { DID, key, token, scope, consent receipt, revocation status }. This is architecture, not a privacy policy.

Who it's for

One foundation.

The individual is the principal. Individuals own their health data and authorize every use of it, every time. Everything else flows from that.

For individuals

You own your health data

A passkey on your device holds your key - nothing to install, no password to remember, no one able to act as you. LifeCare.ID^® knows where your health data is held and enforces your permissions wherever it lives: on the nodes of the LifeCare network, run by your providers, the node itself enforces them; elsewhere, your rights are asserted for you. No one sees your data without your explicit, revocable consent. You enroll through your participating provider; the data stays where it was created. You hold the keys.

For physicians

Honor the patient relationship at scale

Physicians built their practices around patient relationships long before the rest of healthcare caught up. LifeCare.ID^® is the consent infrastructure that enables you to deliver outcomes without surrendering your patients' data to a third-party cloud.

For researchers

Outcomes data you can trust and defend

LifeCare.ID^® makes patient consent the foundation, not the obstacle: every data point is traceable to a patient who explicitly authorized its inclusion.

For developers

Build on the consent layer

Add “Sign in with LifeCare.ID^®” and request consented, purpose-bound access to health data with a few standards-based calls - OAuth 2.0 + PKCE, UMA-pattern tokens, signed consent receipts, all against a published, versioned API contract.

The architecture

Built around data sovereignty.

Most healthcare systems aggregate patient data. LifeCare.ID^® makes this data accessible without moving it. Data stays with whoever holds it - a provider's node in the LifeCare network, a lab, a device maker - and LifeCare.ID^® keeps the map of where it is and the permissions that govern it. Who owns a node and who controls the data on it are separate questions: providers own and operate the network's nodes, the individual controls the data, and every node publishes a signed statement of what it runs. Queries run through federated infrastructure that never touches PHI; the patient authorizes every query through their own identifier.

Cryptographic consent

Each authorization is signed with a key held in the patient's device secure element via a WebAuthn/FIDO2 passkey, and bound to their W3C decentralized identifier (did:web). Recorded as a verifiable consent receipt.

Federated query

Outcomes queries run against distributed clinical sources and aggregate at query time. No protected health information ever moves to a central warehouse.

Zero PHI in the cloud

The network is a coordination layer, not a data store: no LifeCare.ID^® component ever holds a health value, whether a node is a machine in a practice or a virtual one. There is no warehouse to attack, no database to subpoena, no aggregated population to be re-identified. The models run where the data is: zero-egress health AI.

Revocable, auditable, end to end

Patients revoke any consent at any time - tokens die in under half a second. Every grant, access, and revocation is recorded in a hash-chained, tamper-evident ledger.

Don't trust. Verify.

Check what any node is running.

Consent decides who may touch your data. Attestation lets you check what a node says it runs. Every LifeCare.ID^® node publishes a signed record of its code and AI models. Anyone can check in their own browser that the record was not altered and that the key that signed it is the one LifeCare.ID^® lists for that node.

Verify a node How the transparency model works

For developers

Sign in with LifeCare.ID^®

Federate identity and request consented, purpose-bound health data without ever holding a key or touching a raw value. Apps integrate over OAuth 2.0 + PKCE; data sources serve directly under UMA-pattern tokens they validate by introspection. Everything is specified in a published, drift-tested API contract.

Get building in minutes: clone-and-run quickstarts, runnable cURL / JavaScript / Python examples, task-oriented recipes, and a drop-in "verify your node" badge. Concepts, the API reference, the roadmap, and the procurement pack are open to read.

Why now

The legal ground is moving.

Patient data sovereignty is not aspirational - it is where policymakers are converging. State health-privacy law is the leading edge of a national shift toward affirmative consent.

My Health My Data ActAffirmative consent required for any sharing of consumer health data.

Connecticut Data Privacy ActExplicit opt-in required for sensitive personal data, including health.

Colorado Privacy ActSensitive data, including health information, requires affirmative consent.

Federal legislation along the same lines is being drafted now. Any platform that fails to respect patient data ownership will be legally indefensible by 2030. The infrastructure to do it right exists today.
