It seems that "Big Brother" users of modern smartphones can not escape. It turns out, to hear the human voice, you can simply reading oscillations with built-in smartphone gyroscope.An unusual way of listening found Experts on computer security from Stanford University in cooperation with their Israeli colleagues.

Not always possible to separate one person's voice from another, and the sex of the speaker can only guess in 84 percent of cases.Anyway, some practical use of the new technology is already At the present time. For example, listening smartphone hackers have the ability to easily hear the called user numbers. So, attackers have the opportunity to learn passwords, credit card numbers and so on.
