Cant they just make a digiyal signature on a QR code?

[-] gato@feddit.de 16 points 11 months ago

It's very simple to just print the same QR on the cheese by just taking a picture of it. The barrier to counterfeit the cheese is considerably higher if the measure is harder to copy.

Not the same code. Just like serial numbers, a different QR code in every wheel that can be verified on a website, for example.

welcome to the future, where you have to make an account on our website and link your parmesan cheese wheel to it to be sure of its authenticity

[-] Nyfure@kbin.social 6 points 11 months ago

To be fair, this is for retailers, not consumers.
And ideally you can enter the serial-number on a website and know when it was produced and sold, this should be enough for you to know if its yours or not (or e.g. it was resold)

An account is not needed to verify a QR code. Just take a look at what Brazil has done with QR codes. It’s everywhere and, in many places, it does exactly this, to verify the authenticity of a document, for example. I have e-signed documents and what goes on the paper is actually a QR code. It’s not difficult to imagine this being used to fight counterfeit goods.

how do you stop me re-using the same QR code on multiple cheeses?

you can encode the contents of a document in the QR code that you're verifying to make sure it matches

you can't encode cheese into a QR code

[-] SkyezOpen@lemmy.world 2 points 11 months ago

Make the qr code an NFT. Then you can't copy paste it or else you'll have crypto bros having fits in your dms.

[-] andrew_bidlaw@sh.itjust.works 2 points 11 months ago

Make QR a link. Consumer access the website and sees aproximate information about previous scanners with some of items identified as warehouses and shops.

That's the route of cheese for you, and for them. Not ideal but can help you avoid doubles.

Until forgers' cheese sells first and you have false-negatives (:

I find it hilarious that cheese wheels get defended more than money bills rather than having authorized resellers or something alike. I feel it's more like DRM in a sense that making these chips is a business too, and someone found a customer in these scared cheesemakers.

You can encode the first order or link to a tracking website. Depending on the depths of the supply chain this means the wholesellers name needs to match with the factory, production and sale date. If there is 20 steps in between this would get difficult, but such a supply chain should not be trusted in the first place. So it would do the same as the tracker chip. And since there is no encryption mentioned, the signal of the tracking chip could be as easily copied as the QR code.

[-] Primarily0617@kbin.social 1 points 11 months ago

factory, production and sale date

nobody later in the supply chain will have any way of verifying what the production date or factory of their cheese should be

the sale date would only really apply if the same cheese is never sold twice, which seems unlikely and not very scalable

the signal of the tracking chip could be as easily copied as the QR code

it's significantly harder to copy an embedded proprietary ID chip than it is a QR code

No advocating in favor of animal testing, death, or mass euthanasia.

  1. No Non-Leftists, Health and/or Environmental "Vegans"

Veganism is a leftist social justice movement for animal liberation. It is not a diet for your health and it is not for the human environment. This also, obviously, means No slurs/bigotry, Why would you even want to?

  1. No support of PBC

We do not condone or advocate for plant based capitalism. We will never support animal agriculture companies, or any business that exists to extract profit from vegans while funding animal exploitation. We are frustrated these businesses have infiltrated every vegan space and being represented online by ads for TVP and first world convenience food. We're not here to make food aisles bigger, this is about animal liberation. We have all had this convo already which leads us to rule 5

This is a community for memes for vegans and by vegans. There are lots of other places where you can have your debates.

This is a community to jerk about veganism, not a place to promote your ego, new products, or embarrass yourself worshiping a YouTuber. If it is going to a good veganism related cause then message us and it will be approved at our discretion.

  1. No Meta Posting

Meta posting is usually very boring and not fit for a meme subreddit. I wish I could extend this to all the other vegan subreddits. If you really need to post meta about something with circlejerk in the name get a grip and delete your account
