How can I ensure enriched data complies with privacy laws?

Ensuring enrichment compliance starts with thorough vendor due diligence. Before engaging an enrichment provider, investigate their data sources, collection practices, and consent frameworks. Ask specific questions: Where does the data come from? What consent did the original data subjects provide? Does that consent cover sharing with third parties for marketing purposes? What contracts or agreements govern the provider's data use? Request documentation of their compliance practices, including DPAs, privacy policies, and any relevant certifications or audits. A legitimate provider should be able to answer these questions transparently.

Structure your data processing agreements to address enrichment-specific concerns. Your DPA with the enrichment provider should include warranties about the lawfulness of their data collection, indemnification clauses if their data turns out to be non-compliant, restrictions on how they process your subscriber data during enrichment, and audit rights to verify their practices. Ensure the agreement covers GDPR requirements for cross-border transfers if the provider is located outside your jurisdiction.

Implement transparency and control for subscribers. Your privacy policy should disclose that you use third-party enrichment services and explain what types of data you obtain. Consider whether you need to update consent notices to cover enrichment activities explicitly. Provide subscribers mechanisms to view and correct enriched data. If uyou've inferred that someone is in a particular demographic category, they should be able to see and correct that inference. Some organizations offer opt-outs specifically for data enrichment, allowing subscribers to limit processing to only directly provided information. Compliant enrichment requires verifying the data's legitimacy, documenting the legal basis for use, and maintaining transparency with subscribers about what you know and how you learned it.
