Context-based authentication mode selection
First Claim
1. A method of authenticating a user of a mobile communications device comprising:
- receiving an indication that the user desires to unlock the device;
determining one or more device context factors regarding a current context of the device, the device context factors including ambient light;
determining one or more user context factors, the user context factors including connectivity between the device and a vehicle area network associated with a vehicle of the user, wherein the determining of the user context factors comprises determining whether the user of the device is likely driving the vehicle;
detecting a currently selected authentication mode of the device;
evaluating whether the user is likely driving the vehicle, and whether the currently selected authentication mode requires a level of ambient light for one or more of facial recognition, typing by the user, or drawing by the user; and
allowing the user to authenticate using the currently selected authentication mode when it is determined that the user is not likely driving the vehicle, and changing the authentication mode to another authentication mode that includes voice authentication when the user is likely driving the vehicle and when the currently selected authentication mode requires one or more of facial recognition, typing by the user, or drawing by the user, while the required level of ambient light is not met,wherein the mobile communications device comprises one of a mobile phone, a smartphone, a tablet computer, a laptop computer, a personal computer, or an embedded automobile computing system.

Abstract
A system and method for configuring authentication of a mobile communications device entail detecting user context and device context factors and determining whether a current authentication mode is impractical or unfeasible in view of such factors. User context information of interest includes any indication that the user is driving or in a meeting for example. Context factors of interest include for example such factors as light, noise, or user activities such as driving. Based on this user context and device context, if the currently set authentication mode is impractical or unfeasible, then the device may select an available alternative authentication mode and reconfigure the device for that mode.

6. A mobile communications device having adaptive authentication comprising:
-
one or more sensors or interfaces configured to detect one or more user context factors and one or more device context factors, the user context factors comprising connectivity between the device and a vehicle area network associated with a vehicle of a user; one or more user input components through which user authentication can be accepted; and a processor configured to; support a plurality of authentication modes, detect a current authentication mode of the device, evaluate whether the user is likely driving the vehicle and whether the current authentication mode requires an ambient light level and one or more of facial recognition, typing by the user, or drawing by the user; allow the user to authenticate via the one or more user input elements using the current authentication mode when the current authentication mode is not likely driving the vehicle, and switch the authentication mode of the device to another authentication mode when the user is likely driving the vehicle and the current authentication mode requires one or more of facial recognition, typing by the user, or drawing by the user, and the required ambient light level is not met, wherein the another authentication mode includes voice authentication, wherein the mobile communications device comprises one of a mobile phone, a smartphone, a tablet computer, a laptop computer, a personal computer, or an embedded automobile computing system. - View Dependent Claims (7, 8, 9, 10)

11. A method of configuring an authentication mode of a mobile communications device comprising:
-
detecting a current authentication mode of the mobile communications device, comparing user context and device context requirements of the current authentication mode to current user context and device context conditions at the mobile communications device, the user context conditions including connectivity between the device and a vehicle area network associated with a vehicle of a user, wherein the user context conditions comprise a likelihood that the user of the device is driving the vehicle and the device context conditions comprise an ambient light level; and switching from the current authentication mode to an alternative authentication mode when the user is likely driving the vehicle and the current authentication mode requires one or more of facial recognition, typing by the user, or drawing by the user, and a required ambient light level is not met, wherein the alternative authentication mode includes voice authentication, wherein the mobile communications device comprises one of a mobile phone, a smartphone, a tablet computer, a laptop computer, a personal computer, or an embedded automobile computing system.
