Short answer
Identity resolution is the process of linking identifiers across devices, channels and systems, such as emails, cookies and mobile IDs, to a single person or household. The resulting identity graph supports personalization, frequency management and measurement. It uses deterministic and probabilistic matching and must comply with consent and privacy rules.
