Lip Reading Cameras

Umm...creepy?

Lip Reading Surveillance Cameras To Stop Terror
Shouting, face scanning, eavesdropping, X-Ray firing and now lip reading CCTV, do you still feel free?
"Read my lips...." used to be a figurative saying. Now the British government is considering taking it literally by adding lip reading technology to some of the four million or so surveillance cameras in order identify terrorists and criminals by watching what everyone says.

Electronic Design is reporting that the Home Office is interested in a project being pursued by a senior lecturer in computer vision at the University of East Anglia in Norwich, England:

Computer-based lip-reading technology would help video surveillance systems spot people planning a crime or terror attack by literally watching suspects’ lips for clues. Once it finds someone speaking certain key words or sentences, the system would automatically send an alert message to a central console, mobile phone, or other communications device. Police or security agents could then be dispatched to the scene to question the individual.
Of course as with all these Big Brother surveillance moves it cannot be selectively applied and everyone will be subjected to it.

The automatic devices bring to mind the heart-chilling scene in "2001: A Space Odyssey" when HAL (the intelligent computer) tells Dave that, despite all the precautions taken, he knows Dave was planning to disconnect him because he can read lips.

Imagine a place where you cannot step out of your front door and have a conversation with someone without it being monitored. Imagine a place where if you say something considered by the authorities to be suspicious a team of agents is dispatched to your location to detain and question you. Does that sound like a free country?

We have previously reported on the various Big Brother gadgets that the government wants to or already has added to surveillance cameras in the UK. Here is a brief re-cap:

Talking / Shouting cameras - In an incredibly Orwellian move, loudspeakers are being fitted to surveillance cameras throughout major cities, allowing CCTV operators to bark commands at people who drop litter, act in an aggressive manner or loiter. Some of these cameras will even use the voices of children who will be recruited from schools to take part in the scheme and will be shown round CCTV operating rooms on school trips, learning how wonderful the big brother state is and how forcing people to behave in a certain way in public is the essence of a free society.

X-Ray firing cameras - Documents leaked from the Home Office have revealed that the government is looking into using X-ray technology cameras by concealing them in lamp posts to "trap terror suspects". The cameras allow operators to see through people's clothes and look for suspicious items.

Eavesdropping cameras - London police and councils are considering monitoring our conversations in the street using high-powered microphones attached to CCTV cameras that can pick up "aggressive tones" on the basis of 12 factors, including decibel level, pitch and the speed at which words are spoken.

Face scanning cameras - linked into a national database software will allow cameras to scan hundreds of faces a second in crowds of people.

Behaviour monitoring cameras - These devices are programmed to sound an alarm when they spot suspicious behaviour, such as waiting somewhere for a prolonged period of time or just walking in a suspicious way. These have already been deployed in airports and train stations.

Are we seriously supposed to believe that these devices are going to stop terrorism?

Watching everyone all of the time and treating the entire population as suspects is not going to weed out terrorists and criminals. Nor is it an effective way of defending our freedoms against those who we are told wish to attack us because we are free.

If the government were to implement every piece of technology they are seriously considering to add to existing surveillance cameras, we would literally be living in a society ten times worse than that of Orwell's Airstrip One.

We continually have to make sure that does not happen by exposing these things.

Yeah they can try it but they're not going to succeed. Most people won't stand for it. It starts with looking for criminals, then those who disagree with you, then the ones who ask questions until there is nobody left to speak out.

Why don't they try and read these lips. :)

There will be a slightly uproar and then everyone will stop caring. Remember ID cards are still coming.

Well... how can it read lips if you cover your mouth? :p Or aren't facing any cameras?

Damn it. You're right. This makes me sad :(

Right as basically suggested by Infinite Dunes, everyone should buy a V mask

Isn't V's mask a Guy Fawkes mask?

Yes.

I wonder - if I tried to blow up parliament, would I get a day named after me?

And I thought the PATRIOT ACT went over some boundaries. You guys need to riot like your football team lost or something...

Most people won't stand for it? I'm sure that's what was said about Mugabe when he FIRST started throwing his weight around. Look at the country now. This stuff needs to be tackled before it gets to big to handle.

Hahahaha.

There are three reasons this isn't anything to worry about (yet):

1) It's the British Government getting involved with computers! Failure is inevitable! :D

2) Even if they make it capable of reading indivdual words from lips (and I reckon that's some way away by itself), that's nothing without context. "Did you see the new Spiderman film?" "No, I heard it bombed." *Klaxons sound, Word Police are dispatched*... They'd never get any "useful" fnord-hunting actually done.

3) Gottle of geer, gottle of geer...

This might be an interesting area of research (and not just for spying on people), but I don't think we have to actively worry about it yet; it's just someone getting a bit worked up about interest in a research project.
Still, we've got ID cards to bitch about in the short term...

Good luck with that. Reading lips would require analyzing a video. To determine whether or not a conversation was about some sort of terrorist attack one would need to view a fair bit of the conversation, probably multiple sentences. Then one would need to decide whether or not this sounded suspicious in order to alert authorities.

In conclusion, the point I'm trying to make is that computer vision and reasoning is difficult i.e. slow, so given current technology it would probably be a better investment to train security personnel to read lips when monitoring cameras.

On the other hand, this would be a good problem for AI research, I am thinking specifically of neural networks. It is in fact two problems, the first being teaching a machine to do lip reading. The second being teaching a machine to understand the meaning of a sentence.
