Abstract

A device, method, and system for securely pairing mobile communication devices using device movement includes capturing a begin movement, capturing arbitrary pairing movement, and capturing an end movement. The mobile communication devices verify that they are within a secure range during the pairing process. The captured pairing movement may be normalized, depending on the relative orientation of the mobile communication devices. The captured pairing movement data of each mobile communication device is compared. If the captured pairing movement data matches, then the mobile communication devices are successfully paired.
