- sarahb459, on 10/12/2007, -1/+8This is awesome... I worked as a teacher's assistant in a Chemistry lab at the Richard Stockton College of NJ and we did experiments with a similar compound... we obviously didn't get it controlled enough to hold a fingerprint, but I can agree that pressure-sensitive optically active compounds are amazing and their uses are limitless!!! You want to learn how to make your own, Stockton's bookstore sells the lab manual... or take the class... "Experiential Chemistry" with Dr. Jon Griffiths... most interesting class ever!
- zweben, on 10/12/2007, -0/+4Very good idea. I bet it could increase the number of partial prints that can be used.
- jguerry, on 10/12/2007, -0/+3it's "lead" i believe....
- pkulak, on 10/12/2007, -0/+2There's still three parts to security: what you are, what you have, and what you know. Becoming a bit better at the first one doesn't help a lick if it's not paired with at least one of the other two.
- carpespasm, on 10/12/2007, -0/+2hmm, well since most fingerprint readers can be fooled by things like play-doh, i guess it means skin tone play-doh will become more popular ;)
- jnmlmz, on 10/12/2007, -0/+2Motorola has been doing for quite a while. They integrated a medical imaging companies technology into their latent processing workstation.
The truth is that the human eye can only distinguish 32 shades of gray. An FBI quality fingerprint is captured at 256 shades of gray. Add the color and depth, the eye is able to see the shades it could not previously see.
Here is a link to the company that is providing Motorola the technology and press release.

- pretendex, on 10/12/2007, -0/+2Makes me proud to go to UofT.
- neggbird, on 10/12/2007, -1/+2Black and white fingerprints now seem secure enough, at least for the main purpose it is used for, which is ID. This was be cool for locks and other such devices but adding more complexity would only add more potential for bugs to creep into the system. The most annoying this in the world is to have a lock not open when you insert a card or scan you finger.
- dastafarin, on 10/12/2007, -1/+2I can say this is cool, and wouldn't be surprised to see banks jump on this pretty quickly as well.
- mrASSMAN, on 10/12/2007, -1/+2..and yet, no picture of a color fingerprint??
- warpdragon, on 10/12/2007, -1/+2No, the most annoying thing would to have your fingerprint stolen. You can change a password, but a fingerprint is yours forever, and you only have ten, and not all of those will necessarily work. Fingerprints can be duplicated with Play-Doh and Jello, similar to the rubber one in the article, but cheaper. It certainly isn't as easy to steal color, but it is possible, I suppose.
- brandizzle, on 10/12/2007, -1/+2Well...this would mean that you won't have ink on your hands for the next three days after being fingerprinted.
- CrimsonBlur, on 10/12/2007, -0/+1OK, obviously Digg readers are having a hard time comprehending what this article is really talking about. Without even reading the article (which I did later) it was obvious they aren't talking about recording the color of your actual finger. Come on, are people really this stupid or are you all joking?
This compound changes color based on the pressure applied to it, thus it records more information about the fingerprint than traditional methods. The "full-color" statement means that the compound can change colors in many different combinations, instead of a limited color pallette of a few specific colors. The reason this is so awesome is because each person's skin has different elasticity (among other factors) so using this method you couldn't fool anyone by using a faked fingerprint on the end of your finger, and things like silly putty, etc. won't work either because they would leave a totally different color signature than skin would, even if the fingerprint pattern was identical. - Freekie, on 10/12/2007, -1/+1So what happens when you fingers are dirty, will it mess up the color of your fingerprint when you would have alot of dirt or stuff on your skin?
Also, What happens if you burn your finger, and your finger prints change? - jja1990, on 10/12/2007, -0/+0I can proudly say that André Arsenault (you'll know who I'm talking about if you read the article) is my cousin, as well as my little sister's godfather! no joke. its a really cool technology
- compnski, on 10/12/2007, -2/+1I don't think its color as in my skin is peach, but color derived from the pressure and elasiticty of the finger.
- Streyeder, on 10/12/2007, -3/+1Sure, this is all well and dandy...until they test this in a place where the sun shines, sorostitutes graze, and the fake-n-bake turns hands as orange as a tangerine.
- crash2005, on 10/12/2007, -3/+1gets a DIGG from me because its led team is Canadian
- izzybomb, on 10/12/2007, -4/+2Yet not everyone reads slashdot. I have digg bookmarked so I see the more important articles instead of all of slashdots/wired/whatever other news source articles I would otherwise have to wade through.
- alej744, on 10/12/2007, -9/+1wow this is stupid!
lame crap + no picture = no digg (i dont digg anything anyway) - kjd88, on 10/12/2007, -13/+2slashdot reported this earlier.
