We've just updated our company clocking system from a swipe card system to a fingerprint recogition system, and as ususal a few employees are not happy with it "me civil liberties innit". is there some kind of official view on this sort of stuff, as far as i can gather this type of system doesn't actualy store the print but a "map" of a number of features. if im asked the question it would be handy to be able to give a good answer.
Just tell them that the CIA/MI6/Mossad/KGB and Google have promised not to do anything with the prints.
Schweet.
I know nothing about it, but I'd have thought that the company that supplied the system should be able to tell you..?
You would have thought, but the sceptics would say "well they would say that". so i need to have something that cant really be argued against....

That seems to be pretty good! Should make you seem pretty savvy on the subject
As far as I know the scanners make a map of where the unique points of your print lie in relation to each other.
I'm not aware of whether there is an industry standard to how they are mapped ... so it could well be a proprietry mapping algorithm which isn't compatable with other systems ( such as the IDENT1 UK database used by the Police etc )
To me, i wouldn't be too bothered as long as the fingerprint taken for clocking in was just single digit. I would be against all digits and palm print taken.
Most biometrics readers don't actually send a fingerfrint, as pointed out above they convert the fingerprint's points of reference, usually a combination of patterns and minutea from the pad, to a digital signature and then to a control interface (that actually makes the access decision) of some kind, which then authorises that user or not So regardles of the algorithm being used, all the reader is really doing is sending a unique code to the controller to identify the user, then send a message to the device to control access. The only point in the chain on most systems anyway,where the finger print is ever actually used is at the reader itself.
And yes It's usually a proprietory algorithm. The company I used to work for used a 16 bit hexidecimal code. but that could be produced by a biometric reader, a token proximity reader, swipe card, pretty much anything the customer wanted that could be jigged to produce a valid code.
That didn't help really did it ?
