Sounds interesting. I never thought of this way of cracking. People are really quite innovative these days.
I have never heard my keystrokes so closely as i'am doing today after reading this. Hope to develop the skill. Lets see how successful I would be.
So hear it babyIts odd, and i'm not saying i could do this with anyone else, but it is possible! I've lived with my boyfriend for 2 years now. sometimes when he is typing, something little, like a URL for instance, i know what site he is going to even if i'm laying in bed! haha... thats crazy.
I thinks its like the interval between the keys pressed that gives away what you're writing. I mean, if you just write ------ in less than a second, its obvious that you typed google 
yep very true! lol. its just funny because he is a musician so when he is like ----------.--- its like musicscene.org! lol i know that one! and i can just picture it and i turn around and there he is. i just kinda giggle to myself. but its pretty creepy that there are people out there that can memorize something like that in order to get passwords and stuff!!
well maybe not listen to the keypresses by ear, but use a program to record it and then analyze that somehow...possible even in realtime or sumthing...
oh well, nothing to beat fingerprint + eye + piss recognition combined 
oooooo, i read about that this morning! Sounds very interesting indeed. I guess it will be something to do with the sound patterns, and the distance from one key to the next. Also like...most people might hit enter or space a little harder than if they are typing words fast and only just touching the keys enough for them to work. Eg, google.com it will be able to tell how long it took you to press g and move to the 'o' but then you hit 'o' twice in quick succsesstion so it must be the same key. something along those lines im guessing.
Slammer
I doubt that they can listen to a long password is someone types fast. Ill believe it when I see it

Ofcourse they won't do it with ear.
we are talking about "Researchers at UC Berkeley" what do you expect ?
These are the people whose approximations have an accuracy of 96%.
An ordinary person would say 90% or 95%...how can they come up with the figure 96 ? 
By the way, here's the relevant paper - http://www.cs.berkeley.edu/~tygar/papers/Keyboard_Acoustic_Emanations_Revisited/preprint.pdfCan any one tell me where are my frih$
I cant see and m not earning while posting....
oops that was in funny pictures section....prob solved...
Sorry i am new on the forum....
probably not, that depends on the performance of your keyboard i mean it depends on the status of the keyboard that was used.. if its old and dusty, probably it will end up with a monotone sound. it also depends on the speed of the person using the keyboard..
Have already presented the similar scene in the films. Very normal !
guys i can assure u if they want ur passwords there r better and simpler ways to get it eihter than hear it lol
it much easyer nowadays just a program could get u all the combinations possible in it in 5 min so hearing r too time consuming and to difficult cos of different persons speeds, knoledge and keyboards make it nearly impossible to know what they r typing unless u know very well the person
and it would make no sens to get a password of ur m8 or familiar using this method when there r much simpler and easyer ways to do it
Yea, you can use a simple tool that will reveal any user/pass ever typed on the pc and on what and where at.
Makes you think very carefully on how to restrict physical access to your pc such as finger print security, key locks, ect
Wow, this is so not new. Thanks to berkeleley for recycling another idea.
Accuracy depends on having sound samples of the given keyboard, however.
Trying typing "qni ". Don't you hear differences between the letters?
i had ik prog voor cracks
Ok, long time ago I had read about this in a novel, it has become real!
I ill let you know about the novel as soon as I remember its name and author
This may be possible,but I think you shouldn't get paranoid and start singing while you're typing your password.

So hear it baby |
What?!? It´s true because we can listen some like google.com are very easy to remember by sound.
it is a good idea, but I can´t remember all the sound of 100 keys!!!I don't believe this. I'm a musican and a sound engineer and I can tell you the difference just between a 160 k mp3 and a real 16 bit wav and I'm telling you there is NO way someone can hear the difference between you pressing the letter a or the letter k on your keyboard.
I think this coudl be done if they used the same keyboard and all each time but think about it. They are no noise key boards. Touch screen key boards the old heaver ones and the spill proof ones and each one makes a diffrent sound. Als o a person typing faster and proper will amke more noise then a person typing with only and few finger or typing slowly. I am not saying its not possibale but I think that there results would be a little diffrent if these fact was cacualted into there testing. For example I type softer when my girlfriend is here alspped so I will not wake her typing. If i am mad I type fater and harder. All varables would drop the success rate and i think there 90% was under ideal conditions.
impossible and crap
i will be singing and typing next time. i always have music on when im on my computer so i dont have to worry Well, if people can do that, I'm not so paranoid at home, all my family members know my passwords. And in public places like school? I always cover up the keyboard with my jacket and press lightly. Why? Im paranoid about people finding my password. The Jacket muffles the sound anyway. ^^
I don't think we have the right to know others' secret
so even if I know how to crack the password
I won't do this
ppl have the right to keep their secret
That's incredible, i did not notice that any type has a different sound.
Instead of doing studies for every wierd wild and wack thing it makes since if universities all pulled together to study one of the worlds leading killing diseases we would have a lot more effort and probablility of finding a cure for some awful diseases.
I'm afraid this is nothing new, they did it on season one of Spooks (English tv show based on mi5). Only thing is that that aired in 2002. The idea is 3 years old.
Hey thats awesome......
Maybe i could crack my sisters password........LOL
I will try practising it. 
LOL Why???? Universities do not need to be researching yet another way to crack peoples passwords. Sometimes you just need to worry about yourself and not how many people's lives you are able to mess up because of you cracking their passwords and messing with accounts and money. Let people control their own live, and stop being a loser yourself.
I am done I have also read about people listening to ur key strokes etc
Never thought it would become truth
Oh well
Im a uber noober lol
Danltn
Now that is cool. I wonder how they do that. They musit listen really hard. But you know that google example there could be a million other words which you can type in the same way. So it must be the sounds of the keys being pressed. I tried to do it but all the keys i pressed sounded the same except a few.
That's really crazy. Does it depend on where the user's fingers are? because I would assume if you always hit your A key with your pinky or if you hit it with your index finger it might make a slightly different tone.
Wow, very intersing, one step separate they for computers recoging human speech.
That would be really hard, ok first off you can tell the spacebar and sometmes the enter key when presses, but to be able to decipher all of the keys from the e key and the y key would be really difficult, possible someone such as a blind person would be able to do it with heightnened senses of hearing, but for a normal person with common senses I think it would be extremely difficult and nearly impossible to do by the train of thought. And to memorize for one keyboard it might be easy but think of how many different keyboards are out on the market and how many you would have to memorize. Gosh it just seems more and more difficult as you think about it...
I dont think we can ever need to worry or think about this. This is possible for no one nor any virus. 
This is just something which a virus cannot do ---- like handling the hardware.....
Just ; its a news thats it........
this is really odd...weird in a fact. lol
how can anyone figure out what they typed by just listening to the sounds...
arnt all typing keys the same? i mean they sound the same dont they?
Very interesting although I must admit their are much easier ways of getting passwords then this
However, I doubt they incorporated many different kinds of variables that would have made their recognition device more accurate such as different keyboards, people who type with 2 fingers as opposed to 10, people who press keys at different angles etc. Try it yourself...press a button on your keyboard with different fingers and they sound different 
But hey, everything needs to start somewhere, still an impressive feat.
