US 11,601,782 B2 · Multiple device intersection using geo-temporal mobile application data

Abstract

A computer-implemented method for identifying device intersections using application data derived from multiple mobile devices. The method extracts the unique devices identified in a user defined area of interest (AOI) and generates individual geospatial layers for each device. The layers are derived from the metadata containing coordinates and associated timestamps for all available points of the device. Combining the individual layers will produce a convergence surface of polygonal intersections, indicating where devices have shared additional locations outside the initial AOI. Applying the timestamp to the resulting layer with a user defined time interval will generate a probability matrix of association.

Dependent claims

A method of evaluating associations between electronic devices, comprising the steps of:

defining a geospatial area of interest (AOI) and a time of interest (TOI);
identifying devices contained within the AOI and TOI;
selecting at least a subset of the identified devices;
defining a radius and a time interval proximity;
generating at least one individual geospatial layer for each selected device;
creating a convergence surface for the selected devices;
retrieving a set of timestamps for each selected device in the convergence surface;
identifying a timespan for each of the selected devices in the convergence surface based on a first device timestamp and a last device timestamp;
identifying one or more overlapping timespans for the selected devices;
and
generating an association matrix including the one or more overlapping timespans.
