Introduction

Hospitals now ask not whether AI can improve care, but where the data that fuels AI ends up. Data leaving French borders can trigger complex legal scrutiny and limit trust among clinicians.

Galeon answered this question by designing its digital patient record (DPR) around French sovereignty. Since 2016 clinicians have co-created the system, and today it powers 19 hospitals, two of them university medical centres, handling more than 3 million records.

“Sovereignty is a condition, not a luxury,” says Dr Claire Dupont, Chief Medical Information Officer at a participating centre. This statement appears in the DSIH article of 19 October 2026 and frames the entire discussion.

The DSIH report highlights Galeon’s partnership with Scaleway, a sovereign-cloud provider, and its use of Blockchain Swarm Learning® to keep data on-premise while still benefiting from collective AI models.

How does data sovereignty impact AI deployment in French hospitals?

Data sovereignty forces AI to run where the data lives, preventing any transfer outside the European Economic Area.

Legal backdrop

The French Public Health Code and the GDPR require that personal health data remain within the EU unless specific safeguards exist. The HDS certification (2024 edition) confirms that a host respects these rules.

Operational impact

Hospitals using sovereign AI avoid the latency and compliance costs of cross-border pipelines. They can also reassure patients that their records never travel to foreign jurisdictions.

Strategic advantage

Staying within French jurisdiction simplifies audits, especially under the upcoming EU AI Act (see EU AI Act).

What are the legal requirements for health data hosting in France in 2026?

Hosting must be HDS-certified, follow ISO 27001:2022 controls, and guarantee that data never leaves French territory without explicit consent.

HDS certification details

The HDS (Health Data Hosting) referential defines security, traceability and continuity standards for any third-party provider handling health data. The 2024 version aligns with ISO 27001:2022, covering risk management, encryption and incident response.

GDPR obligations

Article 9(2) of the GDPR classifies health data as a special category, requiring explicit lawful basis and data-minimisation. Sovereign cloud solutions simplify compliance by keeping processing within the EU.

EU AI Act constraints

AI systems used for diagnosis or treatment are classified as high-risk. They must undergo conformity assessment, maintain logs and provide human-in-the-loop oversight.

How does Galeon's Blockchain Swarm Learning work without moving data?

Swarm Learning creates a shared AI model by aggregating locally trained model updates, never exposing raw patient records.

Technical mechanism

Each hospital trains a neural network on its own DPR. Model weights are encrypted, sent to a blockchain ledger, and merged into a global model that is redistributed.

Concrete hospital example

Hospital A in Lyon trains a sepsis prediction model on 200 000 records. Hospital B in Lille does the same on its own data set. The two sites exchange encrypted weight updates via Scaleway’s blockchain, producing a model that benefits from both data sets without any record ever leaving either site.

Verification steps

Before deployment, the merged model undergoes a validation run on a synthetic dataset to confirm that no patient-specific information leaked during aggregation.

Which hospitals are currently using Galeon's AI-enabled digital patient record?

Galeon serves 19 hospitals across France, including two university medical centres and several regional public hospitals.

Geographic spread

Deployments exist in Paris, Lyon, Marseille, Lille, Bordeaux, and Rennes, covering both urban and rural catchment areas.

User base

More than 10 000 clinicians actively use the system daily, entering data, reviewing AI suggestions and participating in model training.

Impact metrics

Average reduction in diagnostic turnaround: 12 % after AI integration.
Readmission rate drop: 8 % for conditions supported by predictive models.
Data breach incidents: Zero reports since 2022, attributed to sovereign hosting.

What is the role of Scaleway in guaranteeing European data residency?

Scaleway provides a French-certified sovereign cloud that meets HDS requirements and hosts Galeon's entire AI stack.

Infrastructure specifics

Data centres are located in Paris-Nord and Lille-Sud, each operating under French jurisdiction and subject to CNIL oversight.

Compliance guarantees

Scaleway’s service contract includes a clause that no health data will be transferred to non-EU jurisdictions without the hospital’s explicit consent.

Performance benefits

Proximity reduces latency for AI inference, ensuring that clinicians receive decision support in real time.

How does Galeon's approach affect the total cost of ownership for EHR systems?

By eliminating legacy integration costs and reducing breach risk, Galeon's sovereign model lowers the long-term TCO.

Legacy vs. sovereign costs

Legacy EHRs often require costly middleware to connect disparate modules. Sovereign cloud removes the need for such glue code.

Risk-adjusted savingsAccording to CNIL studies, a single data breach can cost a hospital €1.8 million on average. Galeon's zero-breach record translates into measurable savings.

Financial illustration

For a 500-bed hospital, Galeon's platform predicts a 15 % reduction in annual IT spend, equating to roughly €2 million saved per year.

What steps must a CIO take to ensure compliance with the EU AI Act?

CIOs need a structured compliance program that covers data governance, model transparency and post-market monitoring.

Data governance checklist

Validate that all hosting providers hold HDS certification.
Document data residency for each AI pipeline.
Implement role-based access controls aligned with GDPR.

Model transparency measures

Maintain an audit trail of model updates, weight exchanges and validation results. Provide clinicians with explainable AI outputs.

Post-market monitoring

Set up a monitoring dashboard that flags model drift, performance degradation and adverse events, as required by the AI Act.

How does the traditional AI model compare with Galeon's sovereign approach?

Criterion	Traditional Model	Galeon Sovereign Model
Data residency	Often cross-border	Strictly EU
Regulatory compliance	Partial GDPR adherence	HDS-certified, AI Act ready
Model training	Centralised, raw data pooled	Swarm Learning, no raw data exit
Security breach risk	Higher due to data aggregation	Zero reported breaches
Latency for inference	Variable, often high	Low, local processing
Cost of compliance	Unpredictable, audit-heavy	Predictable, built-in
Scalability of AI models	Limited by data transfer bottlenecks	Scales via decentralized learning
Patient trust	Eroded by data-exit concerns	Enhanced by sovereignty guarantees

What it changes for the CIO, the medical information department and clinicians

CIO / IT department

CIOs gain a clear compliance road-map, reduced need for complex data-transfer architectures, and predictable budgeting thanks to the sovereign cloud model.

Medical information department (DIM) or hospital direction

DIM directors can assure board members that health data never leaves French soil, simplifying audit trails and strengthening alignment with national health strategies.

Clinicians

Clinicians receive AI suggestions instantly, trust that patient records stay local, and can participate in model training without extra administrative burden.

Limits and points of caution

Model performance variance: Decentralised learning may produce models that lag behind centrally trained counterparts for rare diseases.
Infrastructure dependency: Reliance on a single sovereign cloud provider creates a vendor-lock-in risk that must be managed contractually.
Regulatory evolution: The EU AI Act is still being refined; future requirements could demand additional safeguards.
Data quality prerequisite: AI accuracy depends on structured, high-quality data; hospitals must invest in data governance.
Scalability limits for legacy sites: Facilities with very old IT stacks may face costly upgrades to join the Swarm network.
