Claim 12:
13. A system for associating computing devices with each other based on computer network activity, comprising:
a data processing system having one or more processors;
a matching engine executed by the data processing system to:
identify a first linking factor based on a connection between a first computing device and the computer network via a first network node identifier during a first time period, and based on a connection between a second computing device and the computer network via the first network node identifier during the first time period;
determine a number of computing devices other than the first computing device that connect with the computer network via the first network node identifier during the first time period;
generate a positive match probability based on the first linking factor and based on the number of computing devices;
monitor for a second linking factor based on input activity at the first computing device during a second time period, and based on input activity at the second computing device during the second time period;
monitor for a third linking factor based on activity at the first computing device via the first network node identifier during a third time period, and based on activity at the second computing device via a second network node identifier during the third time period;
determines a negative match probability based on the second linking factor and based on the third linking factor; and
a connector executed by the data processing system to link the first computing device with the second computing device based on the positive match probability and the negative match probability.
