Is anyone familiar with this new technique? There's not a lot of detailed information in the article, maybe because of the pending patent.

Re: New fingerprinting technology created
This seems to be the guts of it
The specific method used is a conformal-evaporated-film-by-rotation technique developed to create highly accurate copies of biological templates such as insect eyes or butterfly wings. Both are surfaces that have nanoscale variations.
"It is a very simple process," said Lakhtakia. "And fingerprints are not nanoscale objects, so the conformal coating is applied to something big by nanotechnology standards."
The researchers tested two materials for coating, magnesium flouride and chalcogenide glass -- a combination of germanium, antimony and selenium. The coating material is heated in a vacuum, while the artifact to be coated is rotated fairly quickly to allow deposition over the entire surface.
Look up this site there are a number of references to the research
