Edward Snowden has disabled the GPS, camera, and microphone on his cell phone to reduce his exposure. As most readers probably know, both the microphone and the camera can be turned on even when the phone has been turned off. He uses headphones to make calls. This makes the recent phone design trend away from headphone jacks look particularly nefarious.
“Laser microphones” can capture conversations by shining a laser on a window pane and interpreting the vibrations. However, this isn’t really a cause for worry since there are easier ways to spy on meetings.
With a voice recording (think a hostage tape), analysts can determine the room size, number of people in the room, and even make a stab at the size and placement of objects, particularly if they get more than one recording from the same site.
The Echo was able to pick a voice out of a crowd engaged in conversation. That means it is capable of singling out individual voice. That means it has been identifying individual voices, tagging the as “Unidentified voice 1″, Unidentified voice 2” and so on. It has already associated the voices of its owners, and if they have set up profiles for other family members, for them as well, so it knows who goes with those voices.
Those voices may be unidentified now, but as more and more voice data is being collected or provided voluntarily, people will be able to be connected to their voice. And more and more recording is being done in public places.
So now think of that party I was at. At some time in the not too distant future, analysts will be able to make queries like, “Tell me who was within 15 feet of Person X at least eight times in the last six months.” That will produce a reliable list of their family, friends, lovers, and other close associates.
Amazon Echo is always listening. From the moment you wake up Echo to the end of your command, your voice is recorded and transcribed. And then it’s stored on Amazon’s servers….
It’s unclear how long the data is stored, but we do know that it is not anonymized. And, for now, there’s no way to prevent recordings from being saved.
