Data processing system and method of associating internet devices based upon device usage

Abstract:

A data processing system performs data processing of raw or preprocessed data. The data includes log files, bitstream data, and other network traffic containing either cookie or device identifiers. The data processing system associates devices with device activity history. The data processing system includes a pairing framework for determining device pairs based upon device activity history, a feature vector generation framework for producing feature vectors corresponding to determined device pairs based upon feature values associated within the raw or preprocessed data with devices of the determined device pairs, a scoring engine for determining scores to associate with determined device pairs based upon produced feature vectors, a graph structure including nodes for representing devices of determined device pairs (wherein edges between pairs of nodes indicate determined device pairs), and a clustering engine for identifying respective clusters of n or more nodes within the graph structure that represent respective groups of devices.
