Abstract
Device authentication is based on the ability of a human to synchronize the movements of his or her fingers. A pairing procedure for two wireless devices may thus involve a synchronization test that is based on the relative timing of actuations of input devices on each of the wireless devices. In some aspects a synchronization test involves determining whether actuations of user input devices on two different wireless devices occurred within a defined time interval. In some aspects a synchronization test involves comparing time intervals defined by multiple actuations of user input devices on two wireless devices.
