	<htmltext>With all the sh.... they pump out from the EHT circuitry and SMPS, I would expect them to do a pretty good job of blowing away any microvolts that come from the keyboard.
<p>
So far as this being a practical way of eavesdropping - I don't buy it. There are lots more established methods of discovering what people are typing, plus this seems to completely overlook all the activity from the mouse. Governmant agencies? Nah, if money was an issue, they'd just kick the door down and take your PCs away. if they want to be stealthy they have far more resources to apply to the problem and far more reliable solutions.
<br>A nice lab experiment, but no practical use.</p></htmltext>

	<htmltext>Hey, is this about X.10? That's been around for a pretty long time. Ambient noise doesn't help too much anymore either since you can use it as a carrier wave and then filter out the frequencies you want at a distance. So sometimes the noisier a city gets, (or an electrical line) the further the reach of that particular technology. As far as I know, that one is not yet on the shelves at Radio Shack. DC or AC current make a difference?</htmltext>

	<htmltext>This really is no new discovery. More than 25 years ago, DOD-certified equipment used a form of active noise as a shield around systems used for classified documents. "Tempest-shielded" equipment was highly controlled, and companies responsible for misplacing a tempest shielded system were subject to some pretty severe penalties as well as the immediate revocation of their rights to build or maintain such equipment.

We forget so much in the technology sphere, and it takes very little research to discover ways of accessing systems we thought we had "fixed" long ago.</htmltext>

Each of your clandestine conversations has to be in a different noisy location so they can't set up a directional microphone or bug.
You also have to prevent them from getting a deaf person to lip read you.
(I don't have direct experience with criminal gangs but anyone can observe that they usually aren't brought down by wiretaps.
The big prosecutions of mafia bosses usually resulted from getting an underling to rat on his boss.
) The point is that anyone worried about being spied on can and will take measures to prevent it.Spying on someone is expensive.
Spying on someone's key clicks is particularly expensive and probably won't produce great results.
Someone tried an experiment of bugging an office by shining a laser on the window.
The results were disappointing.
The vast majority of the conversation was uninteresting.
The experimenters decided that no useful information would have been gathered.Tapping telephones and data links is relatively easy (compared with sniffing keystrokes).
Stealing someone's laptop is usually also easy.
Unless I'm taking measures against those kinds of spying, I'm not worried about having my keystrokes sniffed.
If I were at danger of being spied on, I would be much more worried about being betrayed by a 'friend', associate, or employee.</sentencetext>

	<htmltext>I've read both Slashdot articles. They look similar to me. The older one is far superior.

<br> <br>Basically, if you have a keyboard of poor quality that has poor shielding and no noise reduction components, it is possible to read signals. The question is, which keyboards and computers are poorly designed and poorly shielded?

<br> <br> <b>Read the complete story: </b>This PDF, not referenced by Slashdot, tells the whole story: <a href="http://cansecwest.com/csw09/csw09-barisani-bianco.pdf" title="cansecwest.com">CanSecWest/core09 March 16-20, 2009</a> [cansecwest.com] (PDF). Quote from page 41: <i>"This doesn't work against USB keyboards because of differential signaling"</i>.

<br> <br> <i>'March 12, 2009, 02:46 PM -  IDG News Service -

<br> <br>'Inverse Path researchers Andrea Barisani and Daniele Bianco say they get accurate results, picking out keyboard signals from keyboard ground cables.

<br> <br>'Their work only applies to older, PS/2 keyboards </i>[PS/2 connector, not PlayStation]<i>, but the data they get is "pretty good," they say. On these keyboards, "the data cable is so close to the ground cable, the emanations from the data cable leak onto the ground cable, which acts as an antenna," Barisani said.

<br> <br>'That ground wire passes through the PC and into the building's power wires, where the researchers can pick up the signals using a computer, an oscilloscope and about $500 worth of other equipment. They believe they could pick up signals from a distance of up to 50 meters by simply plugging a keystroke-sniffing device into the power grid somewhere close to the PC they want to snoop on.

<br> <br>'Because PS/2 keyboards emanate radiation at a standard, very specific frequency, the researchers can pick up a keyboard's signal even on a crowded power grid. They tried out their experiment at a local university's physics department, and even with particle detectors, oscilloscopes and other computers on the network were still able to get good data.'</i></div>

<tokenext>I 've read both Slashdot articles .
They look similar to me .
The older one is far superior .
Basically , if you have a keyboard of poor quality that has poor shielding and no noise reduction components , it is possible to read signals .
The question is , which keyboards and computers are poorly designed and poorly shielded ?
