Identify and Verify Users Based on How They Type

LinucksGirl writes to share an IBM DeveloperWorks article that shows how to support user verification through keystroke-dynamics processing by modifying the GNOME Display Manager (GDM). You can create and store a one-way encrypted hash of your keystroke patterns when entering your user name. The article shows how to add code to GDM to read current keystroke patterns and permit a user to log in when the characteristics are a match. An interesting idea to be sure but I know I certainly am not that consistent when I type, so I'm skeptical of how well this may work.

Obvious issue

[Gat0r30y]

How am I supposed to log in after a few too many? Wait, maybe thats not an issue after all, maybe its a feature.

Insensitive Clods!!!

[explosivejared]

I don't know HOW to type!!

CTRL-ALT-DEL

[c0d3r]

Dang, I still find it hard to press the C-T-R-L-A-L-T-D-E-L keys hard to press at the same time before entering my password on windows.

I'd be much happier if Blackberries had Breathalyzers before they allow people to email me at 2 AM. Good grief!

It'll never work

[amplt1337]

How on God's green earth am I going to write down my keystroke patterns on a sticky note on my monitor???

All Cell phones , Not just the BBs

[DRAGONWEEZEL]

Please, drunk dialing should be a civil infraction penalized in this manner

for each # called...

1st offense:
        A stern warning.
2nd offense:
        $250 restitution to the victim, 1 months probation
3rd offense:
        Death.

Re:Oww I broke a finger...

[ShieldW0lf]

Biometric authentication is a far, far stupider idea than this is. Yes, not being able to log in when you're drunk is bad, but having to exchange your finger and your eyeball for a new one because someone posted a high-resolution photo of them online is much, much worse.

Accidents?

[blueboy31]

This works great until you lose a finger, thumb, hand, etc in that freak accident. Talk about adding insult to injury -- your own computer won't even accept you with your newfound handicap!

Tin-Foil Story

[chord.wav]

...and when this hashing algorithm was implemented in Javascript, it meant the end for anonymous cowards...

That solves the drinking and commenting problem!

[instantgames]

Since presumably this would also be a kind of keyboard sobriety test.

Cat-like typing detected?

[Lilith's Heart-shape]

I'll settle for getting GDM to distinguish between a my typing and my cat's.
