Haven't noticed it mentioned on this thread - in the field of biometrics, one of the most reliable methods of identifying and individual is through their 'Gait' (the way they move).
CCTV + 'Gait analysis' = panopticon surveillance.
Think it through.

No actual results on accuracy there tho, are there? And as CCTV can be defeated with the addition of a 'hood', varying the way you walk would surey be enough to fool this...and there's no mention of the back end that needs to be attached to this either...
I don't welcome CCTV, but then I'm not obsessivey paranoid about it either...

You know what's funny? I'm really good at recognising people from the way they walk...maybe I could get a job as a human gait-dna recogniser...I could sit around with a god-like view of the world every day 
That ipsotek stuff looks interesting - could actually help make CCTV responsive; the algo flags up an alert to a human operator who then makes the call on whether to call the OB for example.

That's probably because it isn't.Backatcha Bandit said:
If it would was "one of the most reliable methods" why the plan be to link it with lots of other biometrics, including facial imaging, as your own quote makes clear?
Gait is one of a number of different things which are being touted about to reach the Holy Grail of an automated system which can identify people from CCTV footage. None of them are particularly good. None of them are widely used. I really don't see any of them, or any combination, being shaped up to a useful standard anytime soon, if ever (all rely on absolutely tiny, precise measurements and there are simply too many variables in a public space surveillance situation).
That is the aim of that technology - to allow the software to monitor all cameras simultaneously and flag up possible instances of interest to an operator who, unassisted, could only be monitoring a handful at any one time.kyser_soze said:
(The paranoid imply that if the system flags up suspicious behaviour then that's it, you get convicted and locked away ... but the grown-ups know that isn't the case - it simply flags up possibilities to a human operator for consideration in the same way that motion detection works as part of static security systems)

Perhaps it would be as much a mistake to suppose that the fruits of DARPA funded research projects are available in the public domain as it would be to think that you have anything other than a laymans view of how such technologies can and are being used, DB.

In balance, it's only processing speed and data storage that are the big issues - it'd probably take something like ASCII White, or the NEC Global Climate Simulator to actively scan and assess realtime input from even a relatively static crowd - say at a football match - let alone a moving crowd bunched together during the morning rush hour.
And ultimately you'd still need a body on the ground to confirm everything that your computers are telling you...

There's nothing particularly special about gait analysis, it's just one of a whole bunch of different methods. Machine vision is fucking tricky though, particularly when it comes to challenging humans, who are really good at predicting behaviour from all sorts of cues that they probably wouldn't even be able to explain. It'll just remain part of a flagging system for the foreseeable future.
Perhaps I wouldn't be posting in such a way if all I had was a layman's view.Backatcha Bandit said:Perhaps it would be as much a mistake to suppose that the fruits of DARPA funded research projects are available in the public domain as it would be to think that you have anything other than a laymans view of how such technologies can and are being used, DB.
If I post about something factual it is because I have some knowledge of it.
But, hey. If you want to ignore what I post, feel free.
It's called non-verbal communication - for the most part we don't learn it, we don't use it consciously, we don't actually realise that we're using it at all. So it gets a bit tricky coding it in some way that a computer can then look out for ...FridgeMagnet said:

4 years and I still cry sometimes
I accept that I haven't read all the posts and so might be repeating something said elsewhere, in September 2006 there was a report published called 'A Report on the Surveillance Society' which addressed the issues around the amount of monitoring beingundertaken in the UK. It also made reference to how the information could, and was, used. The report was produced 'For the Information Commissioner by the Surveillance Studies Network'. Having read the report I was shocked by the level of intrusion that there is in UK. The report is available as a PDF download.
Perhaps not CCTV, but there are these:detective-boy said:

Shocked? Yes, I knew we were under constant monitoring, but it was the way the monitoring was used to check and control peoples lives that shocked me. As well as the amount of surveillance that takes place in UK.
Yeah ... but you have no control and the zoom is pulled back out so you can't see any detail so they're not really the sort of thing that was being implied (there's lots of other fixed webcam things as well (including Crispy's one in Brixton!)TAE said:

"The Tin Foil Red Sox Cap blocks all harmful mind control rays surreptitiously broadcast by the YES Network, including the ultra-powerful "WTF Rays" that caused Grady Little to leave Pedro in to start the 8th inning of game 7. Order yours today! Operators are standing by."
This is from a Sunday Herald article. Commissioned by the the Information Comission this new report (subsequent to the Sept 2006 ‘A Report On the Surveillance society linked to in post 196) called ‘UK 2017: under surveillance’ is endorsed by the information commissioner, Richard Thomas. He says: "Today, I fear that we are, in fact, waking up to a surveillance society that is already all around us." The authors also say that their glimpse of the future is "fairly conservative. The future spelled out in the report is nowhere near as dystopian and authoritarian as it could be." The following are some excerpts from the report of how 2017 might look…
The Enrolment of Children
What children eat in schools is also monitored by parents, as boys and girls are required to swipe their school card every time they visit the canteen. The card contains information on school attendance, academic achievement, drug-test results, internet access and sporting activities. The card's records are used to assess whether the child has passed or failed their citizenship programme.
"Children," the report says, "are gradually becoming socialised into accepting body surveillance, location tracking and the remote monitoring of their dietary intake as normal."
ID Cards
The report uses two "protesters", Ben and Aaron, as an example of how police might treat dissenters. When they are taken into custody by private security guards in Westminster, Ben undergoes the usual DNA swab, which is analysed instantaneously, and hands over his ID card for scanning. ID cards are still theoretically voluntary, but not having one makes life almost impossible. Aaron is a refusenik and doesn't own a card. That means he can't apply for a government job or claim benefits or student loans. He can't travel by plane or even train. To make matters worse, Aaron is a young black man - meaning he is deemed a "high category suspect" and is routinely stopped and brought in to the nearest police station for questioning.
Once Ben is released, police monitoring systems piggy-back on his hand-held device to track him as he travels across the city. He's also been put on a communications watchlist which means all his internet and e-mail traffic is saved by his ISP and passed to police. As most phone calls are online now, police also get access to these communications as well.
