Kinda scary if this actually happens.
Oh and here is the direct link to the PDF with the EFF addressing the issue: https://www.eff.org/files/2015/10/13/jpeg_presentation.pdf
how would that be enforced i mean anyone heard of the screenshot program???
If a picture were DRMed, it could only viewed with a proprietary program. That proprietary program would probably be running on a proprietary operating system. Because you can only impose DRM with proprietary software. This then gives the developer of that program the possibility to control various things like not allowing screenshots or other methods.
People using free software would be locked out until/unless someone found a way to view the image with free software. At that point, you're right: The people with the free program are essentially breaking the DRM because they have full control of the image at that point. That's when the evil people come along and issue a DMCA take down notice to the hosting facility and have that program taken down.
I am not sure there is a way to restrict a screenshot ... is there? Most screenshot programs simply take a screen scrape on whatever is on screen. As far as I know, screenshot tools are software agnostic and take whatever is on the monitor(s).

A screenshot function built in to the operating system is a software component
in the end of the day- and due to the proprietary nature of the operating
system the developers would be able to simply remove the screenshot feature or
tamper with its functioning so that one could not take pictures of the picture
in question. All things software within a system that are proprietary (the
proprietary viewing program, the proprietary screenshot feature/utility and the
proprietary display system (whatever that may be) could work in tandem to
prevent that sort of thing. The whole point of proprietary code is that the
users have no control over it.
The only way one could take a screenshot would be externally, using a camera.
I think you guys are giving the effectiveness of digital restrictions at stopping unauthorized copying too much credit. It would take a jail operating system to be truly effective at the task, and even with that, it's possible to bypass it entirely by using any transmission to a monitor that doesn't support digital restrictions, perhaps even an analog one like VGA.
Stopping unauthorized copying isn't what digital restrictions are good at. What they're good at is extracting extra money out of legitimate customers. For example, making them pay again to watch the same movie they bought on DVD, but on their phones. If CDs had been defective by design, for example, people today probably would only be able to legally listen to music on portable devices using streaming services they would have to pay to use.
exactly, couldn't agree more. Stallman has debunked that myth, by saying that if there is at least one copy non DRM'ed, which happens sooner or later because DRM is innefective, there is nothing that can be done to stop illegal sharing(technically of course).
If you'll note I never claimed anything about technical effectiveness and was only replying to tomlukeywood's question of "how would that be enforced."
And as to "how" most DRM will be implemented in proprietary operating systems that are like jails where control over what happens is with the the developer of said software and not the user and if they try to take a screenshot with the OS's built-in screenshot software they'll likely be told something along the lines of "Taking screenshots is disabled while this image is being displayed" or some such thing. (Someone I know uses Mac OS X and a similar message appears if you try to take a screenshot while Apple's DVD Player program is running. That doesn't mean you can't run VLC instead to play the DVD and then accomplish the same thing.) That there may be ways to bypass that wasn't the point of my reply. The point of my reply was, again, to explain how it would be implemented (i.e. how people are going to TRY to stop it, not how well or how poorly that will be) in response to tomlukeywood's question of "how would that be enforced." The way around their method of enforcing is easy: Use free software. Then the developer can't add such restrictions to avoid taking screenshots or if they do, others will remove them but again methods of getting around it wasn't my point.
really? taking a screenshot of a movie, what does that accomplish, it's just annoying as hell. It probably won't take too long until you can only install authorized media players in macs.

I'm not really sure I understand what you were getting at although there are reasons to take screenshots of videos. For instance if one is doing a review of a movie (among lots of other scenarios).
Sorry I didn't make it clear. I was stating that there is no reason to restrict users from taking screenshots of movies.
How do I remove DRM from a PDF with free software?
The "DRM" in PDFs is just a flag in the file telling the PDF reader to restrict certain features. Free software PDF readers usually allow you to bypass it.
Evince bypasses it. You can save it into another document.
Isn't that the default in trisquel 7 gnome flashback? When it opens in the default program I get this error.
nable to open document “file:///media/OS/Users/Tyler/Documents/how-to-win-friends.pdf”.
ile type HTML document (text/html) is not supported
Maybe it is format error but I think another program an ebook program said it was drm protected but I am not sure.
Is the file a pdf or a html file?file /path/to/file
One time I bought a book with Trashdobe DRM, so, I couldn't open or read it without Trashdobe proprietary Software. I removed the Trashdobe DRM from book with Python. Now I have my book that I payed and it is mine, not of Trashdobe.
Congratulations!

It would be possible to DRM JPG if the tech is in place to do so. Anybody who has ever taken a screenshot (at least back in the 1990s) with hardware decoding on the video can get an idea of how it would work. Basically what you get is a black blotch where the video is. The graphics card ends up decoding (or in this case decrypting) the video and sending it directly over the wire to the monitor. The modern HDMI cables and the likes all support it actually so you could probably do it such that even the output could only be displayed by a monitor which supports the digital restriction/encryption. At that point the only way to capture the image is to take a picture of the monitor with the output using a digital camera (or film camera for that matter).
With such a simple work-around, it's mind-boggling to think they'd go to so much effort to prevent screenshotting the picture...
