Just a next-generation software and a remote camera to recognize what you type on the touchscreen. Period of great creativity in the world of espionage. After the software that reads what you type on a physical keyboard, the researchers discovered a technique, quickly turned into software, to identify what is happening on a touchscreen display up to a distance of 60 meters.
The trick, as explained by Jan-Michael Frahm, a student of the University of North Carolina at Chapero Hill, is filming the display of the victim, as he writes on the virtual keyboard. At this stage, in fact, the letters are magnified, that is magnified on the screen with a graphic effect that encloses a kind comic balloon. It is not directly recognize the letter is sufficient to analyze the position of the balloon on the screen to discover it. To implement the diabolical plan just another smartphone, equipped with video recording function, although the poor resolution agrees not to exceed a distance of about three meters. With a powerful camera, or SLR camera instead, you get even 60 meters. The condition is to be preferred of course behind the victim, but it seems that the trick also works by analyzing the reflection of a window display, up to distances about 12 meters. And no, not slip into the victim’s home, think about how many windows there are fine in airports, train stations and conference rooms.
Researchers are not certain of fools, and they also noticed that adjacent letters in the keyboard, such as E and R, have overlapping balloon. So the spy program, which is called iSpy, a function approximation that incorporates c’azzecca in 90% of cases. Recognized letters, iSpy is then able to identify and then words, then sentences, and then all the facts you write your smartphone amiably. Including the Access Credentials (read “user names” and “password”) to your online account. Personally I do not think that now we will be invaded by individuals willing to spy on us, but the fact remains that some persons, with a much privacy at risk, would do well to wait for the next plane only reading a good book.
