What legitimate use case can you think of where the benefit of faithfully reproducing currency is not outweighed by the need to prevent the proliferation of counterfeit currency?

Making Monopoly money for the kids? You cannot make counterfeit currency with Photoshop. Paper money has security features that won't even convert to pixels in the first place, like holograms, transparencies and fibers embedded in the paper and such, never mind reproduce by conventional printing. This whole deterrence system is idiotic. People who accept an obviously fake printed copy of a banknote basically deserve…

Absolutely they don't. I get the point that one needs to look out for themselves, but if you say "people", you include the elderly and people with various impairments, and neither deserve to be treated like this.

A few years ago I extracted the CDS logic and got it working in Linux so I could experiment with it: https://twitter.com/taviso/status/902997594460135424 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 th…

Awesome idea! For anyone interested in the concept of adverserial clothing.. Medium size patch defeats/confuses person recognition: https://towardsdatascience.com/avoiding-detection-with-adver...

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?

https://en.wikipedia.org/wiki/Free_Speech_Flag Reminds me of the old t-shirts people sold back when the encryption key for blu-ray was cracked.

It was DVD, but yes. :)

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

I'm wonder when they implement anti-child abuse images detection. Or anti-nudity. Or hate speech in your psd files. Or course, for our safety.

It already started... not in Photoshop, but don't forget the plans Apple had for the iPhones...

I know, but iCloud is not tool for creativity. If we implement political correctness into creative tools, we just put another layer of censorship to self-expression. Publishing on social networks follows.

We just create ultimate dystopian society step by step. Of course because of our safety.

Do anyone actually belive that those "protection implementation" will reduce actual fraud? Criminals will use other tools anyway.

Money can be pretty. Before the euro (last century) a friend had a poster sized version of a 50(?) German Mark bill.

It's not particular beautiful, but I have a £50 in perfect condition. I intend to frame it and put it somewhere, as it has Alan Turing on the reverse. https://en.numista.com/catalogue/note281993.html

Given what's happened this week I think that note has more significance than just Turing.

Might be a good idea to obtain few mint ones and stash them away just in case they don't stick around all that long.

Redesign likely has already been done.

At least in the US, ‘old’ bills are still legal tender. A counterfeit bill pre-holograms and recent security stuff is still usable in public.

The interesting thing is that the US has one of the oldest currency systems. due to the US policy of not invalidating old currency, an old 1920's silver dollar is still legal tender, of course at a market value of several hundred dollars you would be mad to spend it as legal tender.

A counter example is the uk pound, when the uk moved to the decimal pound all the shilling pound notes became invalid. so the us dollar system is older than the current uk pound.

Some people (James Randi in particular) spray starch on real bills to increase the false negative rate. http://archive.randi.org/site/jr/070105quality.html#7 That link also contains an account of the problems someone faced when using that technique.

What are other causes that make the pen fail? How does starch randomly end up on money?

> The effectiveness of the pens may be affected by external methods. Simply having a banknote pass through laundry, depending on the soaps and bleaches used, can cause a bill to fail the test when it is otherwise accepted.

I read that pre-decimilisation it was common to find coins with different monarchs depicted on them, presumably because they last a bit longer than notes.

My understanding is that they are in no great rush to remove ER II notes/coins from circulation, but that all newly minted currency will bear Charles III.

There's also a great joke doing the rounds that most notes already have Charlie on them anyway.

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.

Have you ever heard of decreased vision and impaired sensation? Should people with these disabilities be prohibited from working as cashiers?
