Excerpt
Excerpt We introduce the area of remote physical device fingerprinting, or fingerprinting a physical
device, as opposed to an operating system or class of devices, remotely, and without the fingerprinted device’s known cooperation. We accomplish this goal by exploiting small, microscopic
deviations in device hardware: clock skews. Our techniques do not require any modification to
the fingerprinted devices. Our techniques report consistent measurements when the measurer is
thousands of miles, multiple hops, and tens of milliseconds away from the fingerprinted device,
and when the fingerprinted device is connected to the Internet from different locations and via
different access technologies.
There are now a number of powerful techniques for remote operating system fingerprinting, i.e.,
techniques for remotely determining the operating systems of devices on the Internet [2, 3, 5, 37].
We push this idea further and introduce the notion of remote physical device fingerprinting, or
remotely fingerprinting a physical device, as opposed to an operating system or class of devices,
without the fingerprinted device’s known cooperation |

This paper covers the idea of fingerprinting a physical device once it is already in use. This article combined with a device fingerprint prior to distribution could combine to make this claim.
