Imagine a screen that could tell the difference between the fingers you use to touch a screen.
You could do different stuff with each finger (drawing, left-click, right-click, selecting text).
If a friend touches you screen it would draw in a different color, or not work at all, thereby
rendering all passwords useless, as when you touch you fingerprint is instantly recognized.
A laptop would be just a screen, no moving parts, just the touch screen.
We would have a fresh new look computer, and awesome computer games, and a total new user interface. [link]

What if you cut your finger? And do the ends of my thumbs have a recognizable fingerprint? |
|
| |
We have 10 fingers, if one gets cut the database gets corrected, police can use parts of fingerprints so it should work . |

I like this idea. A couple of points: |
|
| |
1) Setting up the system. |
|
| |
The police match partial prints based on a good 'full' original scan. Obtaining that full scan involves a clean rotation of the finger against the scanner. Achieving that first or even second time requires a trained and experienced cop and/or an experienced detainee who wants to get home quicker. |
|
| |
So, you could set your system up using the same software but need to be aware that it can be quite fussy and takes several goes to get it right. |
|
| |
Open question. Can the matching algorithm and scanner technology work quickly enough to detect a print match without noticeable delay? |
|
| |
I don't belive so. Still, the idea is good. And, with a really good processor, it might work. Granted, it would have some lag, but that can be fixed in the next few years. |
