I had a similar thought when I saw the paper last week that showed masks that don't cover the nose are less effective than those that do. On the one hand, why did we need a study to show this. On the other hand, now we have a study confirming it.
Like, if I actively wanted to evade facial recognition then I now know that a black mask is better than a blue mask.
One would suspect such complaints about the friction between centralism and federalism are widespread across the world.
In reality, LOL!
It heavily depends on the location type - parking lots were way way safer with CCTV presence, but there was no effect in public pedestrian spaces.
Those are frightening odds when you consider the impact such system could have on those "false positives", eg. possible detainment until your identity is confirmed.
The police may have had the resources to check each case in person during the trial but you can imagine what could happen once there is a push for more wide adoption of these systems as a way to save on police resources.
I would also love to see the proportion of people with dark skin tones who were flagged as false positives.
Then what happens to the pictures of non-confirmed positives and negatives? Are they purged from the system automatically or are they kept around for a while? What recourse have the false-positive to not be harassed in the future?
Let's face it, this genie is not meant to stay in the bottle and it's a policing dream to be able to automatically identify potential undesirables, wherever they are. Why not at the entrance of banks and other sensitive places? Like sports clubs and parks and swimming pools. At every corner of the streets maybe?
who says it sensible to check them at all? Basic probability. Let's say the false positive rate is 1%, and there's a criminal among every thousand. That means on chance alone you'll get ten false positives for each actual hit. (the low base rate makes the false positives much worse than they sound, same reason you shouldn't panic if you get a positive test for a rare disease).
That is a ton of work for nothing, a lot of people being stopped without reason, when the saner alternative may have been to not pester anyone at all. Discovering criminality comes at a cost to people who are falsely dragged into it, and creates opportunity cost for the police.
Letting crime happen investigated is not a good solution.
Numbers are difficult to compare since data collection mechanisms are subject to change, but here you go:
The need for CCTV is marketing and gut feeling from my perspective because the numbers say it didn't do much.
Per that article, in 2010 the vast majority of violent crime offenders were black - and I wouldn't be surprised if the victim profile would look similar.
Pure anecdata, but this was 90% of the news I saw. Gang stabbing in park. Gang stabbing at party. Gang shooting at club.
Meaningless without comparison to other countries.
> London is the knife crime capital of the world.
Doubt it. https://en.wikipedia.org/wiki/List_of_cities_by_murder_rate
The statistics were compiled from 2015 and in just the few years since then solved crimes have halved: https://www.bbc.co.uk/news/uk-49029545.
If you and I were to travel back in time to the high trust society before mass surveilance & enquired our police wouldn't deny they held the the monopoly on violence. My friends in the forces of today tell me they feel under siege most days.
Apologies, "London is the knife crime capital of the world." is part of the venacular here akin to "The man who broke the Bank of England".
I think we'd need a comparative trial to really know that.
There have already been a few 'iffy' situations in London where facial recognition trials have caused upsets.
Big Brother Watch has been highly vocal on the subject and worth keeping an eye out for on social media etc
..there, fixed it for you.
With _the_federal_government_ ensuring that 5G covers every inch of the territory enabling economies of scale for low cost SOCs and pricing tiers, the days of WiFi for any kind of mass deployment (doorbells, ATMs, street cams, etc) are ordinally numbered backwards from a small integer. With all fixed location cameras connected in that way, he who controls the 5G controls the world...
Presumably they’ve had this problem for a while.
The other commenters who have noted that there are lots more variables involved (height, gait, etc) are also right of course.
I think China is a world leader in this field of technology, and I fully expect them to have solved this, for better or (almost certainly) for worse. Imagine if you had an organization with virtually unlimited local currency willing to pay researchers/smarter-than-average/average programmers to solve the who-is-that-in-this-picture problem, but also you had no regulation to answer to with regards to personal privacy and/or data access ("it's for national security" gets you close to no oversight in western nations, but not quite China-level). Consider the problem mostly solved. Even if it wasn't, the fact that just about every citizen carries a cell tower/GPS beacon with them should be enough to help narrow down the search space dramatically, even if your algorithm/methods were dogshit (it isn't).
China has created a real life 1984, and tech helped them get here. I don't know whose (including me) conscience that's supposed to be on but just putting it out there.
In real life totalitarian country don't need ro worry about unsolved crime since there ia no one to report on it. Anyone talking about any kind of crime on social media just gonna be slienced or just censored to begin with for spreading rumors.
The problem with those is that it's really hard to get around them. Changing one of the factors isn't going to help. You'd have to identify the most significant ones to change those (if that's possible).
Police Surveillance - Check
Big Tech - Check
That's a damn attractive ad-article already, even without the quotes and fluff. Click-bait topic bingo.
Maybe once we don't look at a person and think "Facemask!", once it becomes normal, we'll retrain to identify folks by eyes, head shape, body language etc. And quit relying on nose and mouth so much.
EDIT: Sorry, it seems that it's more that medical conditions make it unreliable
> Certain eye-related medical conditions and diseases, such as cataracts and glaucoma, can render a person unable to use retina-scan technology, as the blood vessels can be obscured.
The real news is that the error rate for the top algorithms only dropped to 5%. I can't find these numbers in the original report on my phone:
there are even better more expensive balaclavas, but not gonna spam it here with link
Considering that license plates exist specifically for the purpose of recognition (originally by human observers), I don't think it's news in 2020 for anyone to be identifying them via machine vision. If you have a Raspberry Pi and a Pi Camera, you too can participate in this kind of surveillance.
"Antifa" seems to be a symptom of fascism and racism -- like an elevated white blood cell count in response to an infection. I'm not sure the organization even exists. It certainly wasn't a major part of the national dialogue prior to that fatal rally in Charlottesville.
Antifa did exist in the 1930s as the militant wing of the German Communist Party  and whilst working in London in 2012 I saw many organised protests of theirs for different causes than in the prognosis.
If the organisation existed today given the majority have been mobilised through steadfast polarisations, a multitude of grievances and not as cover for potential infiltrators, why would they admit it? It is much more convenient to remain nebulous.
The link adds credence that this is more an insurrection rather than "proud mothers" who it seems were organised to act as shieldbearers to protect the bombers of Americas federal buildings  and not their children to whom they hold a duty. You can see this mass organisation by self-identified antifa-associated accounts #PortlandMoms and scroll down.
The parent site itself, is that one of the splinters of the forum that reddit banned?
And I know about OpenALPR.
And I know facial and license recognition has been around since the 60s.
It's implicit we are talking about the data collection and large scale database and organisational control of that data.
I don't know why that link scares you, but you should learn Tor or AdBlock or Tails or VM's, I don't mind paranoia but lazy paranoia is, well, lazy.
If they are actually doing it, it's a big deal and will make the news. I found the original link, but not that trustworthy, but we will see in the next 24 hour news cycle - https://partisan.space/what-you-need-to-know-about-antifa-un...
