Sorry, hadn't looked at the scanner. Of course, there are coffee cups, doorknobs, etc that you can use.
OT - fingerprints have been faked by at least one law enforcement agency (LEA). They xeroxed someone's fingerprint card, opened the door on the coppier so they could take the copy out after the toner was put on the paper, but before it was fused, and took the "print" off the paper with whatever tape they normally use to pick up fingerprint powder. The defense attorney was able to show that the toner was different than the fingerprint powder the LEA used, so the guy was found innocent. |

One of my contracts is with a dielectric film company and one of my labs has many capabilities. Fingerprints is one of them. I actually tried to use three different forms of reproductions on this and none worked. I was curious how easy it would be since it was new to me. I have a lot of sensitive information on this computer and since it is a tablet PC and I am not there every day I needed to be sure.
I did try to scan prints from glass and aluminum, zinc, copper, silver (all the pure metals in this plant) none worked either.
from the Lonovo website:
Can fingerprint readers be fooled by hackers?
There are a number of known attacks against fingerprint readers. Some are rather intricate, such as building a fake finger out of something like ballistic gel or soft plastic. Currently, there are no known attacks against capacitive slide technology, which is what our Fingerprint Reader offerings are based on. The sensor manufacturers keep on top of these attacks and continually update their devices to resist them.

That comment caught my attention, and although my question has nothing to do with this thread, I can't but wonder if you have considered encryption... it might alleviate some of your concerns.

I do use encryption, but as there is an MIS department and as you know, if anyone knows how to break the stuff, it is the people who set it up on other systems (although, due to my position they cannot touch my computers and haven't) as well as curious and devious people, nothing is enough.
This company is very sensitive to their information. We did not have any competitors until someone walked out with the technology and sold it. Now we have at least 5 legitimate competitors. The founder of this company was the inventor of this technology and he never patented his process, machines, technology, just so no one would know how he did it. For 40 years no one did or could figure it out either.
