AI Act vs GDPR: Differences, Complementarities and Dual Compliance
AI Act and GDPR: two complementary regulations

After the GDPR in 2018, the AI Act is emerging as the second major pillar of European digital regulation. But how do these two texts fit together? Are they complementary or contradictory? And above all, how do you manage dual compliance?

GDPR and AI Act: a recap of the fundamentals

The GDPR (2018) protects the personal data of European citizens. It governs the collection, processing and storage of data. The AI Act (2024) regulates AI systems themselves, regardless of the data they process.

These two texts pursue distinct but converging objectives: protecting the fundamental rights of European citizens in the face of digital technologies.

The role of the DPO in the face of the AI Act

The DPO (Data Protection Officer) is naturally on the front line for the AI Act. Their knowledge of data processing and governance makes them the ideal candidate to lead or co-lead AI compliance.

However, the AI Act adds technical dimensions (model evaluation, bias testing, algorithmic documentation) that may require complementary skills.
