Abstract

Claims (45)

1. A method comprising steps of:

while a mobile communications device is locked and connected to a network, detecting, by a proximity detection module in the mobile communications device, that a key device is also connected to the network, the key device performing a user authentication process;

while the mobile communications device is locked and connected to the network, receiving, by a behavior modification module in the mobile communications device, information from a communication from the key device to the mobile communications device, the information indicating that the user authentication process has been successfully completed, the completed process resulting in an authenticated key device user;

in response to detecting, by the proximity detection module, that the mobile communications device and the key device are connected to the network and in response to the receiving the information, by the behavior modification module, that the user authentication process has been successfully completed, authenticating, by the behavior modification module in the mobile communications device, the authenticated key device user to the mobile communications device; and

based on the authenticating of the authenticated key device user to the mobile communications device, initiating the unlocking, by the behavior modification module, of the mobile communications device.

2. The method of claim 1 comprising:

detecting, by the proximity detection module, that the key device and the mobile communications device are no longer both connected to the network; and

in response to the detecting that the key device and the mobile communications device are no longer both connected to the network, initiating the locking, by the behavior modification module, of the mobile communications device.

3. The method of claim 1 comprising:

upon expiration of a time period of inactivity after which the mobile communications device will be locked, determining by the proximity detection module whether the key device and the mobile communications device are both connected to the network;

if the key device and the mobile communications device remain connected to the network, not initiating the locking of the mobile communications device by the behavior modification module; and

if the key device or the mobile communications device no longer remains connected to the network, initiating the locking of the mobile communications device by the behavior modification module.

4. The method of claim 1 comprising:

after the step of initiating the unlocking of the mobile communications device, periodically determining, by the proximity detection module, whether the key device and the mobile communications device are both connected to the network;

if a periodic determination indicates that the key device or the mobile communications device is not connected to the network, initiating the locking of the mobile communications device by the behavior modification module; and

if the periodic determination indicates that the key device and the mobile communications device are connected to the network, not initiating the locking of the mobile communications device by the behavior modification module.

5. The method of claim 1 wherein the key device comprises glasses.

6. The method of claim 1 wherein the step of initiating the unlocking of the mobile communications device comprises unlocking the mobile communications device into a first mode having a first level of functionality, and the method comprises:

while the mobile communications device is in the first mode, receiving an unlock code;

if the unlock code is correct, unlocking the mobile communications device from the first mode to a second mode having a second level of functionality greater than the first level of functionality; and

if the unlock code is incorrect, maintaining the first mode on the mobile communications device.

7. The method of claim 1 wherein the mobile communications device comprises an operating system.

8. The method of claim 1 wherein the step of detecting that the key device is connected to the network comprises:

receiving a message broadcast from the key device, wherein the message comprises a Media Access Control (MAC) address that matches a MAC address stored at the mobile communications device.

9. The method of claim 1 wherein the step of detecting that the key device is connected to the network comprises:

broadcasting a message from the mobile communications device over the network for the key device; and

receiving a reply from the key device responsive to the broadcasted message.

10. The method of claim 1 , the network including a Bluetooth network or a near-field communication network.

11. The method of claim 1 , the network including a wired connection.

12. A method comprising:

detecting, by a proximity detection module in a mobile communications device, that a key device and the mobile communications device are both connected to a network, the detecting being triggered by the mobile communications device being activated, the key device performing a user authentication process;

while the mobile communications device is locked and connected to the network, receiving, by a behavior modification module in the mobile communications device, information from a communication from the key device to the mobile communications device, the information indicating, that the user authentication process has been successfully completed, the completed process resulting in an authenticated key device user;

in response to the detecting, by the proximity detection module, that the mobile communications device and the key device are both connected to the network and in response to the receiving the information, by the behavior modification module, that the user authentication process has been successfully completed, authenticating, by the behavior modification module in the mobile communications device, the authenticated key device user to the mobile communications device;

based on the authenticating of the authenticated key device user to the mobile communications device, initiating the unlocking, by the behavior modification module, of the mobile communications device.

13. The method of claim 12 , the mobile communications device being activated including being powered on, being woken from a sleep state, or being woken from a power-saving state.

14. The method of claim 12 , the network including a Bluetooth network or a near-field communication network.

15. The method of claim 12 , the network including a wired connection.

16. A method comprising:

while a mobile communications device is locked and connected to a network, detecting, by a proximity detection module in the mobile communications device, that a key device is also connected to the network, the detecting being performed with a display of the mobile communications device presenting an appearance indicative of being turned off, the key device performing a user authentication process;

while the mobile communications device is locked and connected to the network, receiving, by a behavior modification module in the mobile communications device information from a communication from the key device to the mobile communications device, the information indicating that the user authentication process has been successfully completed, the completed process resulting in an authenticated key device user;

in response to detecting, by the proximity detection module, that the mobile communications device and the key device are both connected to the network and in response to the receiving the information, by the behavior modification module, that the user authentication process has been successfully completed, authenticating, by the behavior modification module in the mobile communications device, the authenticated key device user to the mobile communications device;

based on the authenticating of the authenticated key device user to the mobile communications device, initiating the unlocking, by the behavior modification module, of the mobile communications device.

17. The method of claim 16 , the appearance indicative of being turned off caused by the display being turned off.

18. The method of claim 16 , the network including a Bluetooth network or a near-field communication network.

19. The method of claim 16 , the network including a wired connection.
