Beware of iPhones ! It could spy on you.

 A word of caution for iPhone users.It could spy on what you type.The iPhone 4 is so sensitive that it can decode what exactly is being typed on a computer keyboard and can double up as a spy phone.Hackers may be able to spy on your keystrokes if you keep your iPhone  too close to your computer, a group of researchers reported .

A bunch of geeks from Georgia Institute of Technology came up with it by experimenting using smartphone accelerometer - the internal device that detects when and how the phone is tilted.They have ascertained that it can be harnessed to sense keyboard vibrations and decipher complete sentences with up to 80 percent accuracy, and the iPhone is easily vulnerable to it.

According to Patrick Traynor ,the lead of research team ,"We first tried our experiments with an iPhone 3GS, and the results were difficult to read," .

"But then we tried an iPhone 4, which has an added gyroscope to clean up the accelerometer noise, and the results were much better. We believe that most smartphones made in the past two years are sophisticated enough to launch this attack." 

The  hacking technique makes use of a  mathematical software based on highly complex algorithms that can detect pairs of keystrokes, rather than individual letters.And it reveals that no technology can be false proof.
