Isn't falsely accusing a person of theft in public Slander?

[–] nyan@lemmy.cafe 10 points 3 hours ago

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.

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.

Fingerprints as username??

[–] deathbird@mander.xyz 5 points 11 hours ago (1 children)

Funny how even the things "AI" is okay at (pattern matching within a certain margin of error) still can't be used properly.

[–] Ensign_Crab@lemmy.world 4 points 9 hours ago

Those using it don't care if they get false positives, so it's working as far as they're concerned.

[–] WongKaKui@piefed.ca 10 points 14 hours ago

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"

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

[–] elephantium@lemmy.world 13 points 13 hours ago

The list of people so dangerous they can't be allowed to fly, but too innocent to arrest.

[–] vorpuni@tarte.nuage-libre.fr 15 points 18 hours ago (2 children)

But don't worry social credit systems where you're barred from public transport is so dystopian only the Chinese do it.

[–] 4am@lemmy.zip 6 points 16 hours ago

This only way this is true is because we barely have any public transportation in America anymore.

[–] UnderpantsWeevil@lemmy.world 1 points 17 hours ago

You can lose your DL in the US very easily

[–] Deestan@lemmy.world 54 points 20 hours ago (3 children)

I am not going to suggest, encourage, applaud and condone arson as a protest, because that is illegal.

[–] brbposting@sh.itjust.works 7 points 9 hours ago

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

[–] fluffykittycat@slrpnk.net 11 points 18 hours ago (1 children)

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

[–] Paragone@lemmy.world 0 points 8 hours ago

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.

That's a possible life sentence if you get caught. Assuming there's even a single person in the building.

[–] Zeddex@sh.itjust.works 17 points 17 hours ago (2 children)

I guess UK and US governments viewed Minority Report as something to strive for rather than a cautionary tale?

[–] No1@aussie.zone 18 points 16 hours ago

Well, they started with Orwell's 1984, but that was 42 years ago and you can do so much more with technology now!

[–] Buelldozer@lemmy.today -3 points 16 hours ago (1 children)

First the US isn't mentioned in this article. Second this is NOTHING like Minority Report. Your comment is dumber thana bucket of hair.

[–] Zeddex@sh.itjust.works 3 points 14 hours ago

I never said it was? It's called a comparison? Sorry I didn't know invasive police surveillance was a good thing.

High powered lasers will burn out camera sensors. They can do it from a significant distance too.

[–] IratePirate@feddit.org 1 points 10 hours ago

They called him the Mall Han Solo...

[–] toiletobserver@lemmy.world 32 points 20 hours ago

On the one hand, right to refuse business. On the other hand...

[–] Paragone@lemmy.world -2 points 8 hours ago

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