Abstract
Systems and methods are disclosed for identifying portable devices carried by the same person. An example system includes receiving media exposure data over a data network from at least one of a plurality of portable computing devices, motion strings to be received over the data network respectively from each of the plurality of portable computing devices, each of the strings including a successive binary representation of motion over a first period of time, the first period of time divided into a plurality of sub-periods of time, and comparing the motion strings to determine if at least two motion strings match within a predetermined threshold, and identify the devices that produced matching motion strings as being physically carried by a same person.
