The inherent weakness of typical mobile device unlocking
approaches (PIN, password, graphic pattern) is that they
demand time and attention, leading a majority of end users
to disable them, effectively lowering device security.
We propose a method for unlocking mobile devices by
shaking them together, implicitly passing the unlocked state
from one device to another. One obvious use case includes a
locked mobile phone and a wrist watch, which remains unlocked as long as strapped to the user?s wrist. Shaking both
devices together generates a one-time unlocking event for
the phone without the user interacting with the screen. We
explicitly analyze the usability critical impact of shaking duration with respect to the level of security. Results indicate
that unlocking is possible with a true match rate of 0.795
and true non match rate of 0.867 for a shaking duration as
short as two seconds.
