Systems and methods for computing device association are described. One aspect includes receiving first and second network communication data for a first and second computing device over a communication network, respectively. For each computing device, a first and second data set are extracted from the first and second network communication data, respectively. The first data set includes first spatial data and first temporal data associated with the first computing device. The second data set includes second spatial data and second temporal data associated with the second computing device. The first and second data sets are correlated. A first geometric distance between the first temporal data and the second temporal data and a second geometric distance between the first spatial data and the second spatial data are computed. The method identifies that the first computing device and the second computing device belong to a common user.
