Synchronization test for device authentication

摘要

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.

主权项

1. A method of authenticating, comprising:
providing a first indication relating to at least one time of actuation of a first user input device that is associated with a first device; receiving a second indication relating to at least one time of actuation of a second user input device that is associated with a second device; comparing the first indication with the second indication to determine whether the at least one time of actuation of the first user input device is similar to the at least one time of actuation of the second user input device; authenticating the second device based on the comparison; and rejecting, during a synchronization test and after the reception of the second indication, any indications purporting to be representative of at least one time of actuation of the second user input device, wherein the first indication is provided and the second indication is received in conjunction with the synchronization test.
