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 and determining one or more user context factors;
evaluating whether a currently selected authentication mode of the device is compatible with the determined one or more device context factors user context factors; and
allowing the user to authenticate using the currently selected authentication mode if it is determined that the currently selected authentication mode is compatible with the determined device context factors user context factors while otherwise changing the authentication mode to an authentication mode that is compatible with the determined device context factors user context factors.

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.

10. A mobile communications device having adaptive authentication comprising:
-
one or more sensors or interfaces for detecting one or more user context factors and one or more device context factors; one or more user input elements configured to accept user authentication; and a processor configured to support a plurality of authentication modes and to switch between authentication modes based on at least one of the user context factors and the device context factors by evaluating whether a current authentication mode is compatible with the user context factors and the device context factors and allowing the user to authenticate via the one or more user input elements using the current authentication mode if the current authentication mode is compatible with the user context factors and the device context factors, and otherwise switching the authentication mode of the device to an authentication mode that is compatible with the user context factors and the device context factors. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)

19. A method of configuring an authentication mode of a mobile communications device comprising:
-
comparing user context and device context requirements of a current authentication mode to current user context and device context conditions at the mobile communications device; and switching from the current authentication mode to an alternative authentication mode if one or both of the user context and device context requirements of the current authentication mode are not compatible with the current user context and device context of the mobile communications device but the user context and device context requirements of the alternative authentication mode are compatible with the current user context and device context at the mobile communications device. - View Dependent Claims (20)
