Computing system and methods for associating computing devices

A computing system comprising:

• memory comprising executable instructions;
• and
• a processor operatively connected to the memory, the processor configured to execute the executable instructions in order to effectuate a method comprising:
• determining a first set of content items associated with a first computing device;
• determining a second set of content items associated with a second computing device;
• determining whether the first computing device and the second computing device constitute a candidate pair of computing devices;
• in response to determining that the first computing device and second computing device constitute a candidate pair of computing devices, calculating a similarity metric between the first computing device and the second computing device based at least on a common set of content items, wherein the common set of content items comprise one or more content items associated with both the first computing device and the second computing device;
• and
• in response to determining that the calculated similarity metric exceeds a predetermined threshold, associating the first computing device and the second computing device with one another.

A non-transitory computer-readable medium comprising executable instructions that when executed by a processor cause the processor to effectuate a method comprising:

• determining a first set of content items associated with a first computing device;
• determining a second set of content items associated with a second computing device;
• determining whether the first computing device and the second computing device constitute a candidate pair of computing devices;
• in response to determining that the first computing device and second computing device constitute a candidate pair of computing devices, calculating a similarity metric between the first computing device and the second computing device based at least on a common set of content items, wherein the common set of content items comprise one or more content items associated with both the first computing device and the second computing device;
• and
• in response to determining that the calculated similarity metric exceeds a predetermined threshold, associating the first computing device and the second computing device with one another.
