Laser Sniffing Captures Typed Keystrokes From 50-100 Feet
Death Metal writes "Chief Security Engineer Andrea Barisani and hardware hacker Daniele Bianco used handmade laser microphone device and a photo diode to measure the vibrations, software for analyzing the spectrograms of frequencies from different keystrokes, as well as technology to apply the data to a dictionary to try to guess the words. They used a technique called dynamic time warping that's typically used for speech recognition applications, to measure the similarity of signals. Line-of-sight on the laptop is needed, but it works through a glass window, they said. Using an infrared laser would prevent a victim from knowing they were being spied on." (This is the same team that was able to pick up the electromagnetic signals emitted by PS/2 keyboards.)
I would have had first post, but I had to close my blinds to avoid anyone spying on my leet Slashdot posting skills.

dynamic time warp again!

I hear that a pair of binoculars works well for this purpose, too. I'm told that they even work through glass.
Nah. The trick is to memorize a 4096-bit RSA keypair and encrypt your typing.
Use a keyboard which changes the entire key layout every time you press any key.
And the keystroke that was planted in my brain
Still remains
Within the cone... of silence.
You can't take the sky from me...
I'd like to know what sharks are doing with keyboards in the first place.
You can't take the sky from me.

As long as they can't capture keystrokes typed with your hands, I feel pretty safe.
