Identity Resolution
The process of stitching together disparate records and identifiers to determine they all refer to the same person.
Full definition
Identity resolution is a matching process used by many data businesses to assess whether records and identifiers may refer to the same person or household. It can combine deterministic signals, such as an exact identifier, with probabilistic signals derived from overlapping attributes. Different providers use different methods and confidence thresholds, so an opt-out at one provider does not automatically change independent records held elsewhere.
