What is Lawful Basis and Transparency Review for AI Processing?
A lawful basis and transparency review for AI processing is an assessment of whether personal data used in an AI system has a valid GDPR lawful basis and whether the people affected have been given the required notice. It is significant because AI projects can create privacy and enforcement risk if training, fine-tuning, or inference data is processed without a lawful basis or adequate transparency.
In Depth
In practice, this review checks the purpose of each AI processing activity, identifies the controller's lawful basis under GDPR Article 6, and verifies that privacy notices describe the AI use in clear, accessible terms. It also examines whether special category data or other sensitive data triggers additional conditions, and whether downstream uses such as model training, testing, logging, or human review are covered by the stated purposes and disclosures.
For compliance teams, the review is important because regulators can treat AI development and deployment as multiple distinct processing operations, each needing its own lawful basis and transparency analysis. It is most directly relevant under the GDPR and UK GDPR, and it connects to broader obligations around purpose limitation, data minimisation, and fairness; it is also commonly linked to AI governance programs aligned with ISO/IEC 42001 and AI model development under GDPR.
