A 'spy mobile' remotely read messages

Do you value your privacy? Do you worry about the kind of content you send and receive on your mobile? Then, when sending an SMS, you better keep your guard up. A group of researchers from the University of North Carolina has developed a software named iSpy able to recognize the text you type a person on his mobile from a maximum distance of 60 meters . All you need for this to work is a high-definition video and a bit of classical surveillance methods.

In a case of monitoring, if the subject in question is a little careless, perhaps not even need to leave the computer to follow. A GPS tag in a photograph or a brief intervention in a service like Foursquare is sufficient for the location of someone, but this time we do not speak only of their physical location, but from what you send via your mobile phone. It is need to steal or install some form of keylogger remotely. All that is required is to follow at a distance and have relatively reasonable or national high-definition camera that can record video . The rest will not be any problem for this new program called iSpy .

Everything came from two researchers, Jan-Michael Frahm and Fabian Monrose, wondering if the current optical technology could pose a threat to privacy in mobile phones. And the weaker devices based on IOS and Android is almost ironically, a typical user help: Increase the size of the short letters that are pressed on the touch screen . A camera with sufficient resolution video recording of a person sending a text. iSpy does recognize letters enlarged on the screen, and from there forms the text being entered. Some letters are a special challenge, as the case of the E and R due to its proximity, since the distance can seem like the same letter was extended twice, but iSpy has an accuracy of 90 percent.

Smaller letters
iSpy can also work with something like the reflection of the glass screen on the glasses, but in this case, the effective distance is reduced to twelve meters. Using a conventional camera phone other things even more complicated, since the iSpy may only make use of the video if it was recorded less than three meters. As expected, the first line of defense is to block the user's screen, while also being possible to disable the extension of each letter when pressed. Another option would appear housings made ​​of a material that distorts the image when viewed from afar. Even so, seems more remote than this, it has become technically possible. If you write an SMS in IOS or Android, you might want to have a little more careful.
