A few years ago I extracted the CDS logic and got it working in Linux so I could experiment with it:

I had planned to see if I could come up with an image that would still be detected even with significant distortion, and then print it on a t-shirt... The idea being you couldn't open a photograph of me in PhotoShop! :)

I got sidetracked, but I should get back to that.

Awesome idea! For anyone interested in the concept of adverserial clothing..

Clothing intended to trigger and pollute license plate detection systems: https://adversarialfashion.com/

Question: without modifying my acrual license plates, can i paint my car in a way that would confuse license plate readers? False plates elsewhere on the car? Lines to confuse pattern recognition into rejecting the true plate?

I remember there was some successful SQL injection string printed on a "license plate" that took down a national system somewhere, so you can try with some additional license plate-like bars.

False plates will also confuse a human and will be against the rules, likely will get you fined just like driving with consealed ones or without plates at all.

I had the same thought. I made a T-shirt with the EURion constellation on it. It did work, kind of, but not as well as I liked - distance and angle mattered a lot.

My original goal was to wear it for official documentation, but that went less well. It was cut off in my drivers license photo, and I forget why, but I never ended up wearing it for passport photos.

US passports are clear that only your face should be in the photograph. I can't think of any passport, drivers license, or even employee ID that didn't crop the photo at most below the collarbone.

A face tattoo, on the other hand...

they're just freckles, honest!

Finally a good use for human genetic editing.

Reminds me of the old t-shirts people sold back when the encryption key for blu-ray was cracked.

I still think I have my Perl DeCSS t-shirt somewhere in my mother’s basement :D

I still remember a lot of 09 F9 11 02 after all this time.

This and FCKGW-... are permanently burned into my brain decades later.

It was DVD, but yes. :)

AACS, not CSS. DeCSS happened before I was really using the internet

The cover of Mad Magazine #198, when they were finally forced to mess up the aesthetics with a UPC barcode, is instructive:

You really should! That’s a freaking awesome cyberpunk-style idea.

Please release your research. I m really interested how the detection works.

You could sell this image as an nft.

That's the final form of the nft. Where you own a url pointing to a file that can't be opened. There have to be a lot of those in the wild already.

Only in Photoshop in that case so that's not really impossible to open with the myriad of other software.

And even Photoshop can be patched. Software isn't immutable.

Or just sell the t-shirts and get rich… NFT’s are worthless hype

That’s the joke, pretty sure

That IS the joke, beauty fine

The joke is the NFT.

A t shirt is just a real life nft. It's just as worthless.

If worse comes to worse, you can use a T-shirt to wipe your arse, at least. More benefit than any NFT

That's what toilet paper is for. Most people won't do that.

They'll just have the AI blur out the shirt and keep your face.

I just hold up my middle finger directly in front of my face.

How would they blur the shirt if they can't open the file?

Just because Photoshop has this burden of counterfeit deterence doesn't mean other photo manipulation software suffers the same problem. So, since this is a bullshit feature that prevents work from occuring use other software. Now that other software is being used, use something with an AI underpinning to do things like blur people's faces or their shirts or the whatever your AI has been trained to do.

And how is that relevant? The point is to block people from opening the image in Photoshop, nothing else.

Or, you know, stop using Photoshop for implementing stupid things into your day

What? The point is to make a t-shirt that triggers CDS in Photoshop. Without Photoshop the whole point is lost. This is not about protecting anyone, privacy or anything useful at all. It's a gimmick and a fun hack.

AI doesn’t use photoshop

What AI and how is it relevant to this discussion? The point is that you shouldn't be able to open the file in Photoshop, not that a random AI shouldn't be able to view it.
