Brazil's LGPD and Artificial Intelligence: what changes in practice
How the General Data Protection Law applies to AI systems — legal bases, transparency and the challenges of automated decision-making.
Brazilian companies are adopting artificial intelligence at an accelerating pace, yet many still treat compliance with the General Data Protection Law (LGPD) as an afterthought — when it should be a design principle.
Legal bases for processing
Training and operating AI models almost always involves processing personal data. Choosing the right legal basis — consent, legitimate interest or contract performance — defines what is and isn’t allowed. Legitimate interest, in particular, requires a documented balancing test.
Transparency and automated decisions
Article 20 of the LGPD grants data subjects the right to review automated decisions affecting their interests. AI systems that score credit, screen résumés or set prices must offer explainability and an effective channel to contest outcomes.
Compliance is not an obstacle to innovation — it is the foundation that makes it sustainable.
Next steps
Organizations that build data governance into AI projects from the start reduce regulatory risk and earn market trust. The path runs through data mapping, impact assessments and sound contractual clauses with technology vendors.
