Let’s not overlook yet another insidious part of it:
Home Bargains eventually issued him an apology and a £100 voucher as a “gesture of goodwill without admission”, on the condition that the details of the incident remain confidential. Clayton declined: “I just thought: ‘Really, you’re trying to buy my silence?’”
Infernal_pizzaTrying to buy his silence is insulting enough, but they offer a pitiful amount and can’t even be bothered to offer actual currency?
MaeveAt least the deacon who sexually harassed me and tried to buy my silence that time wrote a three or four hundred dollar check, which I promptly cashed, and told the whole neighborhood.
Not only are they trying to buy his silence, they think they can do it so cheaply. Shows their own world view where they think people will fall over each other trying to sell their rights for a hundred.
and its only 100$ instore credit. hope they can sue to expose them, and then you wonder where they are getting the biases from, select all non-whites as thieves.
TrackinDaKrakenI suppose all we can do is refuse to shop in the stores that use this. But, we need to do it now. Because, soon, every store will use this, and we won’t have a choice.
I suppose if they keep getting false positives, they’ll make some change, but who knows?
just cut their internet from the outside before going in.. then pay cash. you know none of this is being ran locally
The company’s website claims that its system has a 99.98% accuracy rate
99.98% accuracy of the people it flags as shoplifters or 99.98% accuracy overall? And if the latter then what proportion of the population are even shoplifters? Could you achieve similar levels of “accuracy” by saying nobody is a shoplifter? Maybe throw in a few positives here and there to make it look like your product does something other than harass the public?
You’re right to question this.
In machine learning Accuracy means the correct % of overall classifications. There’s some other terms like:
- Precision which is the % of correctly identified positives divided by the number of positive classifications. A high precision score would mean that of everyone who flagged as a match you had relatively few who were not actual shoplifters.
- Recall (true positive rate) which is the % of correctly identified positives divided by all actual positives. A high recall score measures how many shoplifters you caught and would minimize false negatives, but at the cost of more false positives.
So in the case of classification of shoplifters ideally you would focus on Precision as false positives are undesired, but if a company doesn’t care about false positives as much as getting the shoplifters they’d focus on Recall. In either event, Accuracy is a poor metric to use or advertise in an imbalanced data set like shoplifting as most customers are not shoplifters so even if the model didn’t classify anyone as a shoplifter they’d still be 99+% accurate.
The first human that exercises the will of a damn clanker on me is going to get pummeled into the ground. You are a human, if you listen to a probability machine, you yourself are playing in the world of non-deterministic behavior.
Could this be a reason to start wearing face masks again like during covid times? If you have an illness it should be more reasonable to do so too.
FreeBooteR69Maybe but it is better to just inform the store you and your family and friends won’t be shopping at that store anymore, good luck with your business.
Then what though? I need food to eat.
Do you not have other stores to go to?
No not in the US. While most Americans (~70%) are within 10 miles (16km) of a grocery store as foreigners would recognize them, the other 30% have either a Dollar General or Family Dollar. Just those two choices. Sometimes both if they’re lucky. For ~10% of Americans they are 30 miles (48km) or more from a grocery store and usually 10 miles from a dollar store.
With rising gas prices and the lack of infrastructure across the majority (>80%) of landmass in the US, many rural Americans have to have 4x4 vehicles in order to just drive to their job and back, so an extra ~3 gallons of gas for groceries doesn’t make sense as anything but a monthly expense; and even then statistically the only thing they could get to is a Walmart which is the most common grocery store in the United States; or just as bad a Kroger Brand company or Albertson’s brand company. Those are the three grocery stores that statistically exist for >95% of the US population, and theoretically if you’re banned from one in a specific brand family you’re banned from all in that brand family.
Oh Dollar general, where they’ve disabled the self checkout but you could disable the security camera, empty the register, before the one part time employee staggers from wherever they are. Maybe there is a conspiracy to make me stand for 20 minutes in front of a camera instead of just enabling the self checkout.
Breaking news: it’s still COVID times, and you would be wise to wear a mask in enclosed public spaces
Lvxferre [he/him]Napkin maths time: 99.98% accuracy, 50k alerts ≃ Facewatch is responsible for the slander of at least a thousand people per month.
But whoever created such system doesn’t care, right? No, because systems like this are designed and used by psychopaths who don’t get that people aren’t just numbers. They only see a failure rate of 0.02%, assume “that’s fine lol”, and if necessary “you” aren’t doing shit, “it’s the bot lmao”.
Fuck all this shit. At those times I’m kind of glad to live in the third world, it means this sort of bullshit takes a wee bit to come here. And if it did I’d seriously avoid any shop with it.

I suspect the claimed “99.98% accuracy” is counting out of all faces scanned, which is a bullshit way to make the tech look good. Most faces are not marked as shoplifters in the database. A system that literally does nothing would probably still have greater than 99% accuracy.
What we really want to know is what percentage of reported matches are accurate, and I bet it isn’t anywhere near 99%.
I had to try to educate sales people what such numbers actually mean.
With fingerprint readers, there are false positives (your finger is accepted, although it should not), and false negatives (your finger gets rejected although it should accept). The chances for both look small, but if you have 700+ people in the system, the chance of a random person to be accepted as one of the 700 is about bigger than 50%. And there was a big chance for any valid user to be logged in as someone else.
Pretty much this. A 0.02% error margin when there are tens of thousands of visitors per year, means it’s almost guaranteed to have errors.
99.9% ^700 = 49.6% chance of no errors occurring.
99.98% ^3466 = 50% chance of no errors occurring.
99.98% ^23000 = 1% chance of no errors occurring.
Pretty much that. The customer wanted to use it for identification and authentification in one go, with lenience for dirty and injured fingers on top.
Fingerprints as username??
Yes, it was intended to be used for identification and authentification in one go. For something between 500 to 700 people, and the customer wanted it to work with dirty or injured fingers, too, so the readers would have to be extraordinarily lenient.
My guess is that the customer watched too many movies.
On the one hand, right to refuse business. On the other hand…
I am not going to suggest, encourage, applaud and condone arson as a protest, because that is illegal.
If it does happen the company has no one to blame but themselves, because when you abuse people like this there will be a backlash, it’s to be expected
Backlash only means something when the entity getting backlashed is somehow hurt by that backlash.
When the company’s immune to accountability, consequences, & responsibility, then .. backlash changes nothing.
The difference-in-leverage between citizens vs the companies doing this is now sooo huge, that there’s no significant chance of accountability or correction ever happening, in many countries.

These shoppers getting booted really steamed me. Individual stores, individual systems: that’s one (uncomfortable) thing. Sharing the data means disenfranchising. And when they go out of business someday the data of the whole country is sold to the highest bidder.

Wish we could fix it legislatively so they don’t say “terrorism everywhere, need camera everywhere”. (One imagines that Flock CEO would love us to constantly wear bodycams…)
btw on the internet gotta wonder if someone’s gonna read that & be like “oh let’s do it with 20 people inside”
That’s a possible life sentence if you get caught. Assuming there’s even a single person in the building.
High powered lasers will burn out camera sensors. They can do it from a significant distance too.
They called him the Mall Han Solo…
The article notes (along with names of shops—vote with your money, if you’re in the UK), that the ID system being used has the usual racial bias (has a hard time with anyone who isn’t white) and also a gender bias (has an easier time IDing men). And that the provider was careful not to mention this until after people started complaining.
Reminds me of the US No Fly List.
No idea how your name gets on there. Impossible to remove. Every attempt to fly is a humiliation
The list of people so dangerous they can’t be allowed to fly, but too innocent to arrest.
But don’t worry social credit systems where you’re barred from public transport is so dystopian only the Chinese do it.
This only way this is true is because we barely have any public transportation in America anymore.
You can lose your DL in the US very easily
so, right after 9/11 i had to fly every 8 weeks for medical treatment. and somehow SLC put me on their Suspicious Travelers List because they’re creeps in Utah. They put a mark on my ticket that indicated me for extra searches every time i flew (until i yelled at the TSA and told them I was flying for medical treatment and threatened to sue them for harassment. i wasn’t, i didn’t want a lawsuit, but it got the searches to stop). they’d toss my bags and pat me down at security and sometimes also at the gate. every fucking time i flew, because i was too deathly ill to stand up for myself.
never got that treatment in SFO.
Funny how even the things “AI” is okay at (pattern matching within a certain margin of error) still can’t be used properly.
Those using it don’t care if they get false positives, so it’s working as far as they’re concerned.
To them it’s more trouble to actually double check or review hits then to just give people a blanket ban if they might could possibly be shoplifters.
Isn’t falsely accusing a person of theft in public Slander?
No no no.
This is fine.
Because you have nothing to worry about if you’ve done nothing wrong and have nothing to hide.
Because mass surveillance apparati are never wrong, and no one ever uses them improperly.
Therefore, everyone who disagrees with me is a paranoid nutjob.
^^^ fucking braindead morons for at least the last 20 years ^^^
I guess UK and US governments viewed Minority Report as something to strive for rather than a cautionary tale?
Well, they started with Orwell’s 1984, but that was 42 years ago and you can do so much more with technology now!
First the US isn’t mentioned in this article. Second this is NOTHING like Minority Report. Your comment is dumber than a bucket of hair.
I never said it was? It’s called a comparison? Sorry I didn’t know invasive police surveillance was a good thing.
I just block people who hurl unprovoked insults.
Soon on TERF Island:
They’re gonna have AI cameras to detect if you “went to the right gender bathroom”, and if AI decrees that you’ve entered the wrong one, they’ll flag you as a “sex offender”, then activate the terminators posted at the store to “eliminate sex offenders”

This means that due-process has to be made a constitutional-right, for criminal AND civil cases..
