Systems and methods for deduplicating viewership data

A system, comprising:

• a non-transitory recording medium including instructions for deduplicating viewership data;
• and
• a processor operably coupled to the recording medium for executing the instructions of:
• obtaining, from each of a plurality of different devices, a different set of viewership data, wherein each of the sets comprises a plurality of different subsets that respectively relate to a plurality of different entities, and wherein each of the subsets indicates a plurality of time-based views of content over a period of time;
• determining a set of values by performing a set of deterministic functions using the time-based views of each of the subsets;
• comparing the values, which relate to same entities and to same time intervals, of the determined sets of each distinct pair of the devices;
• identifying, from among a plurality of the device pairs, a plurality of candidate pairs;
• and
• outputting identifiers of the devices of a first pair.

A non-transitory computer-readable medium comprising instructions executable by at least one processor to perform a method, the method comprising:

• obtaining, from each of a plurality of different devices, a different set of viewership data, wherein each of the sets comprises a plurality of different subsets that respectively relate to a plurality of different entities, and wherein each of the subsets indicates a plurality of time-based views of content over a period of time;
• determining a set of values by performing a set of deterministic functions using the time-based views of each of the subsets;
• comparing the values, which relate to same entities and to same time intervals, of the determined sets of each distinct pair of the devices;
• identifying, from among a plurality of the device pairs, a plurality of candidate pairs;
• and
• outputting identifiers of the devices of a first pair.
