The aforementioned complicated process has the advantage of not
requiring a mold to be made from the victims fingers.  The fingerprint
image lifted from a glass or plastic object is sufficient.

Also, it's fairly simple (but expensive) to build a 3D finger print
scanner:
<https://3d.idintl.com/explore-3d-fingerprinting/>
and print the results with a 3D printer.
<https://3dprint.com/271540/d-defcon-fooling-biometric-sensors-using-3d-printed-fake-fingerprints/>
The behind the display fingerprint scanners use multiple cameras and
3D scanning.  I haven't had any luck with those:

Not a problem.  There seems to be an endless supply of evil geniuses
and overly curious teenagers who can break into anything.

If I wanted your medical records, I would simply go to the appropriate
department at the hospital and ask for a copy of your medical records.
That last time I did that for obtaining some test results, all they
asked for was my date of birth (because they were in a hurry).
