Multiple meter detection and processing using motion data
First Claim
1. A computer-implemented method for determining multiple portable computing devices being physically carried by one person, comprising:
- receiving media exposure data over a data network from at least one of a plurality of portable computing devices;
receiving motion strings over the data network respectively from each of the plurality of portable computing devices, the motion 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, the successive binary representation including a series of values representing motion of respective portable computing devices for each of the sub-periods of time;
comparing the motion strings in a processor to determine if at least two motion strings match within a predetermined threshold; and
identifying the devices that produced matching motion strings as being physically carried by a same person.

Abstract
Systems and methods are disclosed for identifying users of portable user devices according to one or more accelerometer profiles created for a respective user. During a media session, the portable computing device collects media exposure data, while at the same time, collects data from the accelerometer and compares it to the user profile. The comparison authenticates the user and determines the physical activity the user is engaged in. Additional data may be collected from the portable computing device to determine one or more operational conditions of the device itself, including the detection of multiple devices being physically carried by one user. Gross motion strings may also be generated by devices and compared to see if strings match, thus suggesting multiple devices are being carried by one user.
