Linux Biometrics Site Opens Doors

flickerfly writes "A new site to unite the individuals interested in Linux and Biometrics has opened its doors. LinuxBiometrics.com's purpose is to fill the biometrics void in the Open Source community. With the increased adoption of Linux in europe and the recent increase in biometrics interest by the EU, this appears to be a field ready to blossom into heavy adoption and will be in need of OSS support."

      How can any form of biometric software (os or otherwise) be 'good'?

Moreover I just happen to believe that we as humans, being so error prone, can never come up with a fool proof system, irrespective of what a whole bunch of govt agencies would like us to believe.

      Given all of that what scares me is not the fact that these technologies will be error-prone forever but that there will be no humans around to arbitrate any conflicts/problems in most situations (as is wont to happen when ppl start to take a system for granted). I really wouldnt want to be in a position becase a machine/system/software suddenly decides I am a terrorist because my thumb prints are obscured, because I play too many games using a fucked up pad, and taking 'pre-emptive' action.

      Just because the system will be FOSS and a few million eyes will be watching the arch/code does not mean it will be perfect. And at what point of time do we say - 'Oh crap! this is not going to work.'; when a person dies, two ppl die, two thousand non-first-world ppl die?? And assuming ppl do get tech savvy, and put up monitors (the human kind) we come back to the same old question of who monitors the monitors??

      A simple illustration of the problem is the use of ppl (too many, some would claim) in airports in Israel, India, Malaysia and a bunch of other countries which have problems with violent extremism (I hate the word terrorist - but thats a whole another story) and cant spend 10 mill USD per machine for 10 machines per airport.

I just don't understand why in every post about biometrics everyone starts bitching about how it's not perfect. Of course it isn't perfect!! there is NO perfect security system, and there'll never be.

      Biometrics is NOT about 'perfect' security, it's just a new tool which *can* tighten security where applied properly, and which makes authentication easier in many cases. That's all.

      I do work for a company that develops/supports biometric systems (especially fingerprints), but believe me, I don't get paid for saying this, and I won't get a bigger paycheck for lying about this.

      The thing is NO technology or security system is 100% perfect, and that's no reason not to research and develop applications in that field. Biometrics DO work (at least fingerprint stuff), and it's a really efficient way of authenticating identity. Making a fake finger which can actually fool a *serious* fingerprint scanner (ie: not those MS sells for a few bucks) is -way- harder to do than for example copying a credit card, or getting someone's password. Not to say that if someone's on guard by the scanner (for example a guard on a building's entrance or a cashier at the bank), it's almost impossible to get a fake finger through without being detected.

      In criminal applications, latent fingerprints are lifted from the crime scene using one or various techniques, many of which react to the biological components (sorry, I'm not quite sure how to say that in english) left by the (living) finger, which makes it especially difficult for a fake or dead finger to be used to plant evidence.
      Even in that case, the prints in an AFIS system are ALWAYS reviewer by an expert, which is the only person able to determine fingerprint match on a court (ie: legally). And having found a print on a crime scene, or having identified someone on a civil application by fingerprinting is in the end a way of accelerating work, because normally every identity has to be verified by various means for anything really serious.
      Fingerprints allow you to narrow your search to the most likely to be the person you're looking for, then make sure it actually is. The most common way of doing this in police work is finding, say, suspects matching the fingerprints you found on the scene, and then focusing the investigation on those people, to see if they're the man you're looking for. Odds are one of those will be the criminal, and in most cases it helps to find the person in question really quick. Only *then* the latent print might be used as evidence in the court. Otherwise, having your print on a crime scene just means that you where there at some point, not that you committed the crime.

      So biometrics ARE a pretty good way to identify people, but, again, that doesn't mean it's *perfect*. That simply doesn't exist. And I'd take fingerprint recognition to manage my bank account over a magnetic card and a numeric password any day.

      This is one of the problems with biometrics. I would rather someone steal my bank card and demand to know my PIN, rather than having them cut off my hand or cut out my eye.

      For every countermeasure there is a counter-countermeasure. If heat sensors are included, thieves will just use a lighter (or whatever) to warm a finger before using it. I've often thought that retinal scanners should check to see if blood is actually flowing in the veins/arteries in the retina, but this is not (currently) feasible I think. If this countermeasure existed, then no doubt someone would figure out a way to beat it (artificially flowing liquid through a detached eye sounds complicated, but you could probably fool the sensor by casting moving shadows on the back of a detached eye, thereby simulating the proper pulsating effect of veins...). I've also thought that eye-scanners that use the iris pattern instead of retinal pattern could emit a flash of light and monitor the rate at which the pupil contracts. This would be proof that the eye is alive (since it reacts) and could even perhaps guard against people being drugged or stressed. Again, however, I worry that someone would overcome it.

      The exact form of the criminal's counter-countermeasure of course depends on how the device works, but eventually they'll figure out how to beat it.

    New on Slashot: Dorothy Hedgington of Walmo, North Yorks just uploaded her snaps of Scarborough from 1974. Check it out here now.....
