Try as they might, no one owns the web⌠yet.
Maybe itâs time to start pushing other, superior, open media storage and delivery formats and more importantly, support alternate standard creation bodies who have not been bought out, influenced, or infiltrated by Big Media.
Proof that CompuServe did not do in-house drug testing.
Yeah, I know they wanted it pronounced soft-g âJifâ, as in peanut butter, but the word is âgraphicsâ, not âgirafficsâ, therefore the acronym is hard-g âgifâ.
Not trying to reignite an ancient flame war here, just tossing in my $0.02 worth.
Not so easy. Depends on the method used; some are robust even against fairly severe manipulations including partial cropping.
Lots of books written about it.

Sadly, no time to do an in-depth lookupâŚ
From EFFâs article
That's because your software [such as Adobe Photoshop] is secretly looking for security features such as EURion dots in the documents that you scan, and is hard-coded to refuse to let you make a copy if it finds them, even if your copy would have been for a lawful purpose.
One of the reasons why strict open source licenses are such a good idea: The software recognizing the EURion constellation and other security characteristics are provided as a proprietary binary blob and not included in Gimp and other OSS.
Thought. We could use the OSS software to put the EURion (and/or other markers) to various images/documents to steer people away from software (and hardware, some printers/scanners may be annoying about those too) with built-in cops.
An interesting thing could be a test page, a sheet of paper with these images that we could use for point-of-sale testing of scanner/printer/copier hardware before we shell out the money.
Remember how back in the the Twenty Teens we used to use this format called jpeg? Whatever happened to that?
Itâs pointless: if you can decode them for display, you can also re-encode then in standard, non-DRMâd JPG. Because at some point, all that encrypted, DRMâd cruft has to end up as a grid of pixels. Thatâs the entire point of what it means to be an âimage formatâ.
I suppose they could also insist that these images could only be decoded and displayed by licensed software. But that would essentially guarantee that the format will never be used anywhere.
I like the way you think.
The constellation is rather simple, we should crowdsource experiments to establish the base line for as many printers/copiers as possible.
- Does it reproduce the 5 dots?
- Does it reproduce the 5 dots when correctly sized?
- Does it reproduce the 5 dots when they are within a rectangle sized like a banknote?

Not only that. At some point it has to be displayed.
The resolution of cameras is often higher than of LCDs. Ideally we can get the photo of the screen including the screen-door-effect lines between pixels. Once we have that, itâs not so difficult to reconstruct the original image pixel-perfect. There will be some loss of accuracy in brightness information, but if we shoot in RAW we get more than 8 bits per pixel and can play with that afterwards.
For a manual workflow it is a lot of effort. But once established it can be automated, including tricks like taking more photos of the screen to allow use of cheaper cameras with not-so-high overhead.
I spit on the Internet yesterday, just so you know.
#NSFW!
I am not sure how that helps. The cases where you choose the format are never the problem. Itâs about the cases where someone else makes that choice for you. Itâs not just the few companies like those offering streaming video who feel very strongly about DRM. There are many more out there who like the idea but go without for now because for them DRM is not worth the downsides yet. And there are others who may not even like DRM but are vulnerable to pressure to use it. Third parties may not be willing to license their content anymore without it. Users may demand that they do something against others stealing their uploaded contentâŚ
Smell my finger.
Iâm not here to help but to poke fun at the idea of using DRM on an image format. The idea that you can invent a digital lock that cannot be circumvented (usually easily) is foolish and short sighted. The problem isnât one of rights management but rather of the chosen business model.
Sure, it will be around for a while and for me thatâs good thing. It makes figuring out what businesses are run by fools and which ones have real legs much easier. Meanwhile, Iâll keep poking fun at the idea.
This is hypothetical, right? Itâs not that youâve done this with porn beforeâŚ
Nah, although when I was a teenager, I did hide most of my porn steganographically in the digitized home movies. An picture is worth a thousand words, but it takes about 20,000 frames of video to hide a picture in the least significant bits.
3 very simple steps gets you around this,
1-press prnt screen
2-paste then crop it in any paint or photo editing program
3-save it.
There are also screen capture programs for windows, linux, macOS X, BSD ect that will capture the specific area you want and then let you save it all in one shot.
I think that would forever wreck porn for most peopleâŚhere let me just open the video of my mom and aunt betty talking to grandma at the family bbq, and run it through steganosis, and voila spankey time.
Long time ago I saw some attempt to DRM images shown so this would not work. I think it was Microsoftâs Terraserver, the old and moldy predecessor of Google Earth. Was there only for a relatively short while, apparently it worked poorly. I think I got through in some way but donât remember exactly how, it involved the raw image tiles fetche before beng shown though. Was late 90âs or early 2000s.
I wouldnât be surprised if there were new attempts for this, with newer technology, scheduled for later once the DRM in images takes hold so the printscreen route gets closed too.
Letâs prepare the physical photo-of-the-display route as a contingency, and as a demo that such efforts are futile.
You can do it from the commandline with ease.
