1. An audience measurement system comprising:
at least one processor; and
a non-transitory computer-readable storage medium having stored therein instructions that, upon execution by the at least one processor, cause the audience measurement system to perform a set of operations comprising:
obtaining, from a first meter at a first audience measurement location, a first set of unknown signature segments;
obtaining, from one or more second meters at one or more respective second audience measurement locations, a second set of unknown signature segments;
selecting a candidate unknown signature segment from the first set of unknown signature segments, wherein the candidate unknown signature segment meets a threshold length;
comparing individual signatures of the candidate unknown signature segment with individual signatures of one or more unknown signature segments from the second set of unknown signature segments;
counting a number of times that the individual signatures of the candidate unknown signature segment matches the individual signatures of the unknown signature segments in the second set of unknown signatures segments;
determining that the candidate unknown signature segment is a matched signature segment when the number of times meets a counter threshold;
and
in response to a determination that the candidate unknown signature segment is a matched signature segment:
identifying, based on online activity associated with the first audience measurement location, media identifying information associated with the matched signature segment; and
storing the matched signature segment in association with the media identifying information in a signature reference database as a reference signature.
