Event triggered pairing of wireless communication devices based on time measurements
First Claim
Patent Images
1. A method implemented by a wireless device of pairing with a connecting device, the method comprising:
- detecting a bump event, wherein the bump event can be based on either sound or motion;
sending an authentication request to the connecting device responsive to the bump event;
receiving first time information from the connecting device responsive to the authentication request;
authenticating the connecting device based on the first time information;
sending an authentication reply to the connecting device responsive to authenticating the connecting device, said authentication reply containing second time information about the bump event to authenticate the wireless device to the connecting device; and
allowing exchange of user data with the connecting device upon receiving an acknowledgement that the wireless device was successfully authenticated by the connecting device.

Abstract
An event-triggered pairing mechanism allows pairing wireless devices having short range interfaces (e.g., Bluetooth devices) by bumping the wireless devices together. A wireless device being paired with a connecting device detects a bump event; exchanges time information about the bump event with the connecting device; authenticates the connecting device based on the exchanged time information; and allows exchange of user data with the connecting device based on verification of the exchanged time information. Once the devices are paired, user content can be securely exchanged between the devices.

6. A wireless device capable of exchanging data with a connecting device, the wireless device comprising:
-
a short-range radio transceiver for communicating with other wireless devices; a processing circuit unit operatively connected to the transceiver and configured to; detect a bump event, wherein the bump event can be based on either sound or motion; send an authentication request to the connecting device responsive to the bump event; receive first time information from the connecting device responsive to the authentication request; authenticate the connecting device based on the first time information; send an authentication reply to the connecting device responsive to authenticating the connecting device, said authentication replay containing second time information about the bump event to authenticate the wireless device to the connecting device; and allow exchange of user data with the connecting device upon receiving an acknowledgement that the wireless device was successfully authenticated by the connecting device. - View Dependent Claims (7, 8, 9, 10)

11. A method implemented by a wireless device of pairing with a connecting device, the method comprising:
-
detecting a bump event, wherein the bump event can be based on either sound or motion; receiving an authentication request from a connecting device responsive to the bump event; sending, responsive to the authentication request, an authentication response containing first time information about the bump event to the connecting device to authenticate the wireless device to the connecting device; receiving, from the connecting device, an authentication reply responsive to the authentication response, the authentication reply containing second time information about the bump event; authenticating the connecting device based on the second time information; and allowing exchange of user data with the connecting device if the connecting device is successfully authenticated. - View Dependent Claims (12, 13, 14, 15)
