Abstract
Methods, apparatus, systems and articles of manufacture to perform identity matching across audience measurement systems are disclosed. An example apparatus includes processor circuitry to execute computer readable instructions to identify a first one of a plurality of search spaces in a data structure based on a query event, the data structure based on audience measurement events corresponding to a first audience measurement system, the query event corresponding to a second audience measurement system, determine the query event and a first audience measurement event in the search space are a candidate match when a distance between the query event and the first audience measurement event satisfies a threshold, generate a profile for a first user identifier based on the audience measurement events associated with the first audience measurement system based on the candidate match, the profile including the second user identifier but not the first user identifier, and provide the profile to the second audience measurement system without the first user identifier.
