Abstract
A method for seamlessly authenticating users of a first and second device is described. The method includes: determining a set of first signatures for a first device; generating a set of second signatures for a second device; comparing the set of first signatures with the set of second signatures; and based on the comparing, granting a user authentication status if a difference between the set of first signatures and the set of second signatures is less than a predetermined tolerance threshold, and rejecting the user authentication status if a difference between the set of first signatures and the set of second signatures is more than the predetermined tolerance threshold.
