Authentication using physical interaction characteristics
First Claim
1. A method for user authentication on a mobile device, the method comprising:
- obtaining physical interaction characteristics information for a user of a device, the physical interaction characteristics information including finger angle, the physical interaction characteristics information being measured as the user utilizes the device;
generating a user physical interaction characteristics profile; and
recurrently comparing continually measured physical interaction characteristics information with the user physical interactions characteristics profile in order to consistently authenticate the user without the need for passcode information or additional authentication information, wherein a confidence score provides a graduated scale for determining how frequently passcode information or additional authentication information is requested, wherein if the confidence score is higher than a first threshold, then no further information is requested, and wherein if the confidence score is higher than a second threshold but lower than the first threshold, then only biometric information is requested, and wherein if the confidence score is below the second threshold, then passcode information is required.

Abstract
User physical interaction characteristics information or the way a user physically interacts with a device is analyzed to aid in authenticating a user of a device. User physical interaction characteristics information such as swipe speed, finger area, finger conductivity, finger angle, device angle, movement patterns, acceleration, etc., provide signatures that are distinctive for particular individuals and possibly unique if measured to a sufficiently high level of precision. In some examples, a device measures finger positions, finger pad sizes, moisture level, acceleration, displacement, and changes in finger pad size for a particular user and compares the measurements to physical interaction characteristics measured during subsequent usage of the device to verify that a user is an authorized user.
