But before you panic...

The researchers admit that the results they have achieved are not good enough to present a threat at this moment, but they also noted that improving the speech recognition algorithms could lead to better and even usable results in the future.
Is it me or are we getting dangerously close to "select blury image from sector A3 and enhance" from TV land?

Deckard in Blade Runner. I win.

I don't think we're close I think we're there.

I used to be with it, but then they changed what `it` was.
Now, what I`m with isn`t it, and what`s `it` seems weird and scary

1...Your phone is never off when it is on standby. it can be switched on remotely.

2..The only way to ensure your phone is off is remove internal battery.

3...It took a long time till the authorities told us that you could be pinpointed to the nearest cell tower, and so they can know your whereabouts. Modern smart phones with GPS apps, can let authorities know where you are to the nearest metre.

4...it took even longer till we knew that all phones within a cell mast region can be switched on remotely and all conversations via the phone microphone recorded. This was used a few years back in a FBI sting on some criminals in a restaurant and all the conversation was picked up by screening phone calls.

5....God knows what else is hidden away in the computer code within in modern smart phones to help big brother

If your phone is off, it's off. If you think it's off because the screen is off, then that's your own problem. :)

But if you turn your phone off, it's entirely off apart from a really tiny low power circuit that monitors the power button and battery life.

But yes, if you just let it go into standby, it's not off and everything you said above is mostly true for some phone models!

Actually its probably more like 3 metres, but that's still pretty accurate. And it's not always been so easy to pinpoint mobile phone users, it's a side effect of the technology required to share as many phones as possible with a single cell tower.

The technology is quite interesting!

Probably a few bugs, but your real problem isn't big brother with phones these days, its social media companies like Facebook. ;)

Glad you agree on most.

OFF and STANDBY.....depends on your firmware of the phone if it can be switched back on.

"Now come the caveats. For one thing, phones that are turned off may not actually be turned off. "If the NSA elects to modify your phone's firmware, removing the battery is the only way to ensure it's actually 'off,'" tweetedMarsh Ray, who works on Windows Azure active authentication at Microsoft."
