Quick Answer

AI and data compliance requires linking every data flow to a written rule. Audit systems, formalize a policy, monitor continuously, and train teams: here is a proven method for structuring the governance of your AI projects.

The Problem: Operational AI Without Governance

Your teams are already using AI to summarize reports or classify emails. Nobody knows exactly what data is being transmitted or what legal basis it relies on. This situation is the Achilles heel of compliance.

In regulated organizations, every piece of data triggers an obligation: limited retention period, restricted access, traceability of processing. Poorly controlled AI creates invisible vulnerabilities. The risk is not the tool itself, but the document pasted into it yesterday afternoon.

DATALIA supported a CPTS (Center for Post-Acute Care) in centralizing its administrative and medical data. The challenge: ensure that the AI used by teams does not violate HDS and GDPR obligations. Here is how to structure an effective approach.

Key Regulatory Framework

Before formalizing governance, you need to understand the applicable regulations. These vary by sector, but three recurring pillars emerge: protection of personal data, traceability of processing operations, and algorithmic governance.

GDPR and Sensitive Data

The General Data Protection Regulation requires a legal basis for each processing operation. Consent is not automatic: it must be free, specific, and revocable. Health data, such as that handled in a CPTS, benefits from enhanced protection.

GDPR Article 9: Health data is prohibited unless a specific authorization applies. In a healthcare facility, AI cannot process this data without a precise legal basis.

AI Act: Requirements for High-Risk Systems

The European AI Act classifies AI systems into four risk levels. High-risk systems, such as those used for credit assessment or patient classification, must meet strict requirements: data quality, traceability, and explainability.

AI Act, Article 11: High-risk systems must be designed with mechanisms ensuring traceability and performance. Compliance requires an evaluation before market deployment.

HDS and Hosting

For healthcare organizations, hosting medical data requires the HDS label (Health Data Host). This involves annual audits and enhanced security controls. An outsourced AI service must rely on a certified host to remain compliant.

Step 1: Audit Your Information Systems

The first step in AI governance is a complete mapping of data flows. Which applications send information to an AI? Through which API? Under what legal basis?

Concretely, in a regulated environment:

• List all data entry points (forms, emails, shared files).
• Identify which personal data flows through them.
• Verify whether each external AI used transmits data to the service provider.
• Document the full chain: source → API → model → output → archiving.

We observed, during an audit at a European fintech, that thirty operational algorithms had no written record of their usage context. Governance starts here: making the invisible visible.

Operational Deliverable: AI Audit Checklist

Objective: Assess whether an AI system complies with the GDPR and the AI Act.
To gather: System architecture diagram, list of processed data, contracts with AI providers.
Method:

1. Identify the data category (personal, sensitive).
2. Enumerate the applicable legal basis (consent, legitimate interest, legal obligation).
3. Evaluate the AI risk level (AI Act: minimal, limited, high, prohibited).
4. Check for the presence of a processing register and an impact assessment.
5. Compare technical safeguards (encryption, logging) against the specification.

Output: A compliance score (0-3) and a roadmap of priority corrective actions.
This checklist works for internal AI or outsourced services. It fails if the architecture diagram is not available.

Step 2: Formalize an AI Policy

An internal AI policy defines what is allowed, how, and by whom. It contains two components: authorized use cases and usage rules. Without this, every deployment is an exception.

Authorized Use Cases

The policy lists approved use cases: for example, customer feedback analysis, real estate prequalification, or reservation regionalization. For each use case, it defines authorized data, approved models, and required human oversight.

In a real estate agency, automated prequalification can rely on declared income but not on health data. The policy defines this boundary.

Usage Rules

Usage rules require: mandatory use of an approved model, prohibition of pasting sensitive data into public AI, logging of every interaction in a register, and the ability for a user to override the model in case of proven error.

These rules are binding: an employee using unauthorized AI exposes the organization to compliance risks.

Step 3: Implement Continuous Monitoring

Compliance is not a state, but a process. It requires continuously monitoring AI outputs, inputs, and environment. A model can drastically change behavior if its training data is modified.

Monitoring relies on three pillars:

• Audit trail: every AI call is logged with its context.
• Data control: filters block the transmission of sensitive data.
• Human review: a process allows contesting or correcting automated decisions.

DATALIA.App, DATALIA’s sovereign AI, is designed to meet these requirements: hosted locally, integrated with internal applications, and subject to detailed logging. Discover how DATALIA supports digital transformation: DATALIA →

Step 4: Train Your Teams

Compliance most often fails due to misuse. Targeted training on the GDPR, the AI Act, and best usage practices helps reduce this risk. It must reach all potential users, not just IT departments.

For leaders of regulated organizations, training must demonstrate concretely: how a data breach can be sanctioned, why uncontrolled AI is a regulatory debt, and how a well-designed process protects the organization.

Real-World Use Cases

CPTS: Centralization of Medical and Administrative Data

DATALIA deployed a custom ERP for a Center for Post-Acute Care. The goal: centralize administrative and medical data while respecting HDS and GDPR standards. An internal AI, hosted locally, assists teams in summarizing patient records.

Instead of using an external model, the AI connects only to necessary data, and every interaction is logged. Result: data re-entry between the administrative and medical departments disappeared, and no sensitive data leaves the internal network.

European Fintech: Customer Feedback Analysis

A European fintech wanted to automate the analysis of its multilingual customer feedback. Rather than outsourcing to a third-party service, DATALIA deployed a self-hosted sentiment analysis model. The system follows the principle of data minimization: only the feedback text is analyzed, without retaining any exploitable history.

Before / After Comparison

Common Mistakes

1. Mistake: Allow the use of ChatGPT to summarize internal documents without oversight.
   Why: This violates the GDPR and confidentiality principles. Anyone sharing a confidential document with a public AI exposes the organization to significant risk.
2. Mistake: Outsource AI without using an HDS-certified host.
   Why: For a healthcare organization, this violates Article 36 of the European regulation on healthcare security, rendering any subsequent analysis invalid.
3. Mistake: Believe compliance is limited to a signed document.
   Why: Compliance is a living process. It requires continuous monitoring and regular updates to controls.

Best Practices

• Integrate AI governance from the design phase of a project, not afterward.
• Define a clear policy of authorized uses and approved models.
• Mandate logging of every interaction to track decisions.
• Regularly train teams on data and AI risks.
• Establish a human review process for contested decisions.

Compliance and Legal Framework

AI and data compliance is based on an evolving legal foundation. Here are the key regulations to know:

AI Act (European Regulation No 2024/1689)

Adopted in 2024, this regulation is gradually coming into effect. It bans AI systems with unacceptable risk (e.g., facial recognition for criminal risk scoring), regulates high-risk systems, and requires transparency for generative AI.

AI Act, Article 5: AI systems designed or used to restrict a third party’s access to a good or service based on that party’s identity are prohibited. This covers cases like algorithmic discrimination.

GDPR (General Data Protection Regulation)

The GDPR applies to any processing of personal data. It requires lawfulness, fairness, and transparency; purpose limitation; data minimization; and controller responsibility.

GDPR Article 5: All data must be collected for determined, explicit, and legitimate purposes. Undeclared AI usage violates this principle.

Combating Shadow AI

Shadow AI refers to unofficial use of AI tools within an organization. It is particularly dangerous in regulated environments, as it creates invisible data leaks from the compliance team’s perspective. The best defense: a strict usage policy combined with a high-performance internal host like DATALIA.App.

Limitations of the Approach

Governing AI and its data does not solve all challenges. Internal models remain limited by the quality of provided data. An incomplete knowledge base leads to hallucinations, even when properly controlled. In addition, ongoing team training is essential: a forgotten policy is quickly bypassed.

Finally, the performance of a sovereign model may differ from large public models. This gap is acceptable for organizations subject to strong obligations, but it must be measured and acknowledged.
