Abstract
Techniques for resetting authentication for touch-enabled devices are presented. When a user authenticates to a mobile device a touch profile (TP) is recorded. Each subsequent time the user unlocks a locked mobile device via touch, a new TP is noted. The new TP is compared to the recorded TP and if the deviation is within an acceptable tolerance, the user is permitted access to the mobile device without re-authentication. When the new TP is not within the acceptable tolerance of the recorded TP, the user is forced to re-authenticate before access is granted to the mobile device.
Claims18
A method, comprising:
- capturing touch attributes as capacitance and inductance readings when a user is authenticating to a touchscreen of a mobile device with authentication credentials from touches of a finger of the user when the user provides the authentication credentials through the touchscreen;
- comparing the touch attributes to last saved touch attributes that were last saved in a previous authentication performed by the user to access the mobile device and updating the last saved touch attributes as the touch attributes;
- setting a duration for a time until the authentication credentials are to be re-entered by the user through the touchscreen based on the comparing;
- periodically updating the last saved touch attributes for the user as the user touches the touchscreen during operation of the mobile device;
- and
- variably adjusting the duration for the time based on the periodically updating by increasing the duration or decreasing the duration.
3 more elements
A method, comprising:
- establishing and periodically updating a time out period for providing authentication credentials for accessing a mobile device based on current touch interactions of a user touching a touchscreen of the mobile device and based on comparisons between the current touch interactions with a touch profile maintained for the user, wherein the touch interactions and the touch profile include capacitance and inductance measures for a finger of the user touching the touchscreen, wherein establishing and periodically updating further includes variably increasing or decreasing the time out period;
- periodically updating the touch profile based on the current touch interactions;
- wherein establishing further includes setting a shorter period of time for the time out period when a difference between a comparison of the current touch interactions and the touch profile grows larger;
- and
- wherein establishing further includes setting a longer period of time for the time out period when a difference between a comparison of the current touch interactions and the touch profile grows smaller.
2 more elements
A mobile device, comprising:
- a processor;
- and
- a touch profile manager configured to:
- i) execute on the processor, ii) set a time out for which a user has to enter authentication credentials to unlock the mobile device for access, iii) determine the time out period based on comparisons between current touch interactions of the user with a touchscreen of the mobile device and a touch profile maintained for the user, wherein the current touch interactions and the touch profile include capacitance and inductance measures for a finger of the user touching the touchscreen, iv) update the touch profile based on the current touch interactions, v) continuously update the touch profile based on subsequent touch interactions of the user during operation of the mobile device, and vi periodically update the time out period based on updates to the touch profile by increasing or decreasing the time out period, vii) setting a duration for a time until the authentication credentials are to be re-entered by the user through the touchscreen based on the comparing, and viii) variably adjusting the duration for the time based on the periodically updating by increasing the duration or decreasing the duration.
