    I also wonder if they'd grossly underestimate the complexity of the whole thing, like we tended to do with ecosystems and biological organisms. Something like "no way this one random half-row of pixels on the left and the four pixels in the bottom right have a completely different meaning than the rest of the pixels!" Also, I figure, it would be very difficult to reconstruct the mask patterns if you don't already know the formulas in advance. Someone might be able to figure out the codes that use the simple masks, but I figure, there'd still be many "unreadable" QR codes left that use the more complex masks.

Regardless of what specification you're implementing, I always recommend "mentally executing" the algorithms for at least small test cases, as when you inevitably need to debug your implementation, you will be forced to do so anyway, and it increases your familiarity with what it should be doing. As the saying goes: "how can you tell the machine what to do, if you don't know how to do it yourself?" For those who want to go the extra step and try the error correction by hand too, this article will be useful: https://en.wikiversity.org/wiki/Reed%E2%80%93Solomon_codes_for_coders https://en.wikiversity.org/wiki/Reed%E2%80%93Solomon_codes_f... (Side note: the example image of a QR tattoo evoked slight feelings of trypophobic disgust.)

  This is how I was taught encryption algos - by hand on paper (simplified like fewer rounds in des) and they've stuck with me in a lot more detail for over a decade.

My pet peeve: WTF PEOPLE ARE NOT PUTTING A CLEAR TEXT URL NEXT TO THE QR CRAP?!?!? Especially when the QR code itself points to a URL shortener.

  I think the forced tracking is half the point.

    An example of this and candidate for worst use of a QR code is found on Wifi APs provided by AT&T. A sticker on the device shows a convenient QR code that will get you connected. If you're thinking it uses industry standard Wifi schema well you don't know AT&T very well. Instead it sends you to att.com. That's right, in order to connect to the wifi so you can get online you must first be online so you can get the password from a website. Fortunately they still print the SSID and password on the back. But it's clear that AT&T would rather you go through their telemetry portal instead. (And then there's how the signal on it was so weak that it couldn't penetrate interior walls more than 10 meters away. But that's another story.)
  - unpopular42 3y ago
    What forced tracking? If you're going to visit the URL, there is no extra tracking that can be provided by the QR or the shortener. Same if you aren't going to visit it
    - ArnoVW 3y ago
      The QR code means that you can include a tracking id into the URL
- tgv 3y ago
  There’s no reason for it to be the same URL. It could be used to give a false sense of trust. Perhaps that’s why?
rreichel03 3y ago
This is really neat! I’ve wanted to know the QR code contents a few times without actually scanning with my phone so I actually built a super simple app to do this. Nothing fancy, just dumping the raw contents of the code to a string. https://apps.apple.com/us/app/barcode-qr-scanner-rawcode/id1636758263 https://apps.apple.com/us/app/barcode-qr-scanner-rawcode/id1... Happy to add any features folks might be interested in!
- 0cf8612b2e1e 3y ago
  Super interested. As with most things Apple, the lack of control is infuriating, and I hate how the QR scanner auto visits the scanned link rather than just decoding the data.
- AnonC 3y ago
  I thought I’d take a quick look to see what your app offers. Here’s some feedback: * On launch, it asks for Camera permission. I declined and the app crashed. Next launch, it opens to the blank screen with a (scan) icon and an Edit option, both on the top right. Tap on the scan icon and the app crashes. Tap on Edit and it changes to Done (there are no previous scans, obviously). It should ideally provide instructions to enable Camera permissions in the Settings app and also say why it needs it and how it’ll be used. * The App Privacy section for your app declares that it collects usage data and diagnostic data. It would be good to know more details of what’s collected (preferably in the app description). Generally, people wouldn’t expect such a (simple use case) app to collect and transmit information (unless they explicitly ask for it to be done).
- sir 3y ago
  Just FYI, you can also do this with the inbuilt Shortcuts app - create a shortcut to scan a QR code then copy its contents to the clipboard for example.
- jkepler 3y ago
  Use a better QR scanner app. I use Privacy Friendly Apps' "Privacy Friendly QR Scanner", which always presents you with the scanned URL or text in the app before doing anything, and asks you to verify that you want to visit the site. It also includes the ability to generate your own QR codes. See https://secuso.aifb.kit.edu/english/105.php https://secuso.aifb.kit.edu/english/105.php for that and other apps developed by that research group.

> 99% of the QR codes you encounter don't have any missing bits I see a lot of cutesy QR codes out there that include a logo in the center. These are basically intentionally damaged and depend on error correction to recover the missing bits that are covered by the logo.

    This QArt technique can be extended with error diffusion dithering... Then the uncontrollable pixels can be hidden in areas of the image which would normally be grey, with the uncontrollable bits error contribution passed onwards to the controllable regions of the image.

    These are cool and definitely a much more interesting hack than just sticking a company logo in the middle of the code in Photoshop. But I've never seen one of these in the wild.

How do camera apps recognize where the QR code is in the image, and what part of the image it should decode? I guess it also often has to some processing on it, as it will be scewed/bent/etc. Looking at this guide, it's easy to understand the steps. But I don't get how one actually would apply them in code to a picture of a QR code. How?
- pjot 3y ago
  QR codes have certain zones that scanners look for. To determine orientation scanners look for “alignment markers”.
  - phoronixrly 3y ago
    Do you have an article that goes into the details of implementing a reader, and does not just tell you 'use pyzbar'?
    - stavros 3y ago
      That would probably be a machine vision problem, but I'm also curious to know how you turn the pixels of a photo into a series of bits.
- alex_suzuki 3y ago
  Typically by looking at „runs“ of black and white pixels (after image has been binarized/thesholded). For a QR code marker, you would look for a 1-1-3-1-1 pattern, which would indicate that this image row crosses a QR code finder pattern.
  - kaoD 3y ago
    But do they do this at different angles? If so, which? How do they deal with (possibly partially) obscured alignment markers? How do they determine the angle and size of squares? How does one sample each square (center point, average of square, min, max...)? Should I convert my image to grayscale first? If so... which of the RGB-to-grayscale methods should I use for best results? Should I pre-process the picture to enhance sharpness and reduce focus artifacts? Should I bruteforce each frame of the video stream in look for the alignment markers? Etc. etc. I think I have the general idea on how all that works, but... isn't there an official spec/algorithm on how one is supposed to do this? The devil is in the details.
xg15 3y ago
One thing that cleared up some confusion for me: The tattoo photo shows a version 2 QR code (as he writes) but the schematic images are for a version 1 code[1]. That's also why the bottom right alignment pattern is missing in the schematics. He didn't forget it, it's just not there in a v1 code.

- larusso 3y ago
  I also saw this. So one would then simply leave this part out on the way down? Is the alignment pattern always on the same location? I guess so.
  - xg15 3y ago
    I think the pattern has a fixed location that is defined by the version. And yeah, that was my understanding as well, you just skip the corresponding bits when doing the "zigzag reading". But I'd also like to see an example, in particular as that would be different from how the other "large" alignment patterns are handled.

Is there any reason why so many different masks are required and why the mask patterns are so elaborate? In particular the last few masks seem mostly designed to make life hard for (human) decoders :)
cornholio 3y ago
While I understand the teaching approach, this sound like the type of task which, even if it came up as a completely random one-off need, I would feel is much easier to solve in code. The inevitable bugs in my script are at least repeatable and I can iterate until I have a solution, whereas a single bit error in the manual process will waste the entire effort with no progress. And experience has shown that, more often than not, such hack scripts find ways to grow into mission critical services. Sure, it's an ancient Mayan qr code that is unique in the world and we just so happen to have found precise decoding instructions; but are you sure the one of the stone bits isn't just a piece of fossilized bird poo that was not present in the original? Are you sure all the stone pieces were found? are you sure no other ancient qr codes will be found in the future? Life is too short not to automate everthing.
- sshine 3y ago
  To me, decoding a QR code by hand is a cool feat, like solving a Rubik’s cube. It is very unlikely that you will ever need to do it. And like you said, it’s an excellent way to teach implementors of automated QR code readers/writers.
YuccaGloriosa 3y ago
The idea that the ability to decode could be lost makes me me wonder what info you would need as a kind of Rosett Rosetta stone for a future or alien civilization. I'm thinking what would you have on a wall of stone? Would it be possible to represent the whole decode process with all options, and do it purely pictorially?
- hyperman1 3y ago
  The seti project sent such a message. See https://en.m.wikipedia.org/wiki/Cosmic_Call https://en.m.wikipedia.org/wiki/Cosmic_Call which points to https://www.plover.com/misc/Dumas-Dutil/messages.pdf https://www.plover.com/misc/Dumas-Dutil/messages.pdf . Read annex B of that message. We spent a night decoding it with minimal hints, which was reasonably easy. Basically, page 1 defines numbers as dots, binary and their own symbol set. Then they define math operations. This allows them to describe some physical and chemical relations, from which the metric system is derived. This allows them to create descriptions of physical thing which, combined with some crude graphics, let them tell about our home planet. If that's possible, explaining qr codes should also be possible
