Re-identification

As explained in First-Party Data Activation

Re-identification is the process of linking supposedly de-identified data back to a specific individual.

Re-identification links supposedly de-identified data back to a specific individual. In privacy-centric marketing, the risk grows when customer or engagement records are combined with other data sources. section 2.3.1

Data may appear non-identifying while still revealing audience characteristics indirectly. Demographics, purchase history, email interactions, social-media activity, and operational records can contribute to a richer profile when connected. section 2.3.1

Combined marketing records

A marketing dataset without obvious personally identifiable information may still expose audience demographics or interests when matched with other customer or operational data. Consent and protection remain essential before using such records for personalization. section 2.3.1
