I am trying out fprint on a Lenovo E460 laptop with a fingerprint reader
that uses the vfs501 driver. Reading through the security notes wiki page,
it looks like some drivers may or may not write fingerprint data to the
hard drive:


I have successfully tested scanning one print, yet despite storage of this
print in fprint-demo, I do not see any files written to /var/lib/fprint.
However, looking at the source code for the driver makes me think it deals
with image data:


(That being said, I'm not super proficient in C, so maybe I'm misreading

Is there perhaps a better way to determine/confirm how this driver handles
the capture/verification of the fingerprint?
