Microsoft Fingerprint Reader

The other day I heard a strange series of noises coming from Bryce’s office so I popped in to take a look.  Turns out he was messing around with his new Microsoft Fingerprint Reader, looked super cool.   Bryce had a second one that he “loaned” me so I could try it out too.  Since I always strive to be as “cool” as Bryce I jumped on the opportunity.

 

I hooked up the device and quickly had it reading my fingerprint,  set up as easy and while I really appreciate the ability to take an imprint of all 10 fingers,  I figured two would be enough especially since I don’t spend too much time playing with powertools these days. 

 

Mapping fingerprints to logins was a snap, I did this for several web sites that require credentials as well as my email requires credentials cause I use (RPC over HTTP).  All was good.  I was a little disappointed that I couldn’t use this device login or unlock my computer but I find it quite useful anyway.   Turns out however if you use fast user switching, which I do on machines at home, the reader can be used to switch users based on fingerprint.  I haven’t tried this yet because all my machines at work are domain joined.

 

Later that day Ken stopped by and noticed the device took a careful look at this and said “I bet I could crack this”.  I quickly put my hands under my desk and said, “yeah I’ll be watching my fingers carefully, and by the way no knives allowed at work!”  but Ken (being the creative genius he is) had other ideas (clearly he watches CSI)., something about lifting a print and latex, etc..   Ken loves a challenge so I wouldn’t be surprised to see him attempting to lift a print from my reader sometime in the near future.  I am however still secure because my machine is locked and can’t be unlocked with the reader and the settings that are necessary to map the are safely secure behind a gold old fashioned password.

My Crypto prof would be turning in his grave(if he was dead..which he isn't). Seems biometrics are a big security risk. ie. If someone can get their hands on your "fingerprint" which is really just a long bitstring, you can't do anything about it. You can't change your fingerprint like you can passwords. Just something to ponder about. They are all cool and stuff but would you trust your bank account being linked to one of those (assuming youv'e got more than 50 dollars in there) :-)

Who needs latex, you can defeat fingerprint readers using gummi bears, and the method for doing so is a solved problem.

I recently purchased the full-blown keyboard with onboard finger print reader and wireless mouse. Nice!

One drawback I had not considered, however, was that the keyboard was "USB Only". I'm betting it has to do with extra power or speed required to drive the finger print pad, but it won't work in my Belkin KVM switcher. :(

Time to buy a new switcher, I guess. :)

I purchased the MS USB fingerprint readers when it first came out. I returned it within three days. What I can't figure out, is why MS decided to leave the red LEDs on 24/7??! I had it laying next to my keyboard, to the left of my left hand. Those LEDs are in a position where they, at that position, point directly up at my eyes. So, the entire time I'm coding, I have red LEDs shining in my eyes. WTF?

Nuno: No, the software does not support protecting of folders :(

It also does not support Mozilla or Firefox, so I will probably be returning. There is just too much it WONT do to justify the price.

Come on, people!! A little objectivity here!! To be fair to Microsoft, they have never said this fingerprint reader was a security device or marketed it as such, and have even actively encouraged users not to treat in that way. It is merely a useful, labour-saving device. Use it as a security device at your own peril!!! The problem I have is that it doesn't work through my Belkin USB hub - it used to before my reinstallation - and the keyboard is not - and never was - recognised at boot, so I have no way to access the bios unless I install my old keyboard!! Any ideas as to a solution/s???
