I

The brain

AI-native platform.

Federated learning, clinical models, sovereign data. The common foundation for the three other pillars.

Architecture

Three layers, from governance to action.

Couche 3

Action

AI agents, drones and robots execute at the point of care, for clinician and patient.

Couche 2

Collaborative intelligence

Federated learning, clinical knowledge sync, anti-bias safeguards.

Couche 1

Governance & trust

Zero-knowledge proofs (ZKP), on-ledger consent, automated GDPR / AI Act compliance.

Models learn without ever moving patient data.

Federated learning

Patient data no longer travels.

Rather than centralising records, MedicalCity sends the model to the data. Each institution trains locally; only the learnings — never the raw data — are synchronised.

01

The model is distributed to each facility.

02

Training happens locally, on data that never leaves.

03

Only aggregated, anonymised gradients return to enrich the global model.

Data sovereignty

Built for trust, by default.

Hosted in France

Health data hosted in France, on HDS-ready infrastructure.

End-to-end encryption

Encryption at rest and in transit; keys held under sovereignty.

GDPR by design

Minimisation, traceable consent and right to erasure built into the platform.

AI Act compliance

Risk classification, audit logs and documented medical evals.

Interoperable standards HL7 FHIROpenEHRSNOMED CT (placeholders, to be confirmed)

Technical roadmap
