Secure PDFs from printing, downloading

Postby FireFly9 » Fri Feb 09, 2018 4:46 pm

I am looking for an extension to make pdfs NOT downloadable or printable.
I tried the Secured PDF Embedder for Joomla - JoomlaKave
but it doesn't work as far as I can see.
I tried to do it directly using Acrobat DC but firefox allows the printing and downloading despite the security settings associated with the document.
Another one CopySafe PDF Extension for Joomla CMS - ArtistScope
seems to require a monthly server rental fee to host the files.... as far as I understand it.

Does anyone have a suggestion for an extension to secure pdf files and ebooks, etc.

Thanks

Forget it. It's simple impossible to protect something you can see on monitor from printing.

They have to be downloadable otherwise the viewer won't be able to read their contents.

Or have I completely misunderstood you?

We don't want people to be able to download or print. Just view the pdf to read it.

If you can see it you can download / print it.

Sorry, but it's not possible to do this. If people can view a PDF file on a screen then they're able to save and/or print it. This has nothing to do with Joomla. If you have a burning need to control this feature, please refer the matter to Adobe.

Well the developers of some extensions are saying it is possible. I just haven't found one that works yet.
Adobe has settings for protection, but they don't work with Firefox, which they say, is due to firefox not complying.

Man, just give up. They say you need SPECIAL BROWSER for it. :D
How can you imagine it?

another one

"Extension that allows you to embed your PDF file as a PNG image. For those who don&#039;t want users to download and view PDF file."

How can you protect pages from downloading and printing with this? They download it as PNG and will make own PDF :D

I don't know. I am not a developer, but I assumed this could be done. For instance an app that makes the pdf into image files then shows those files in some sort of image viewer (like lightbox). This way the pdf is readable, but not downloadable. People do this for their images to protect them from getting stolen. I figured there would be an extension like this for pdf pages.

@FireFly9: You have your answers; you've done your research. I don't know any more than what I know and what you've told us. It's really not a Joomla issue.

Export PDF to PNG have nothing to protecting your data. Lightbox also cant protect it from downloading or printing.
This solution only for peoples who just know less compared to you about how internet works.
So you can spend your money and time and "protect" data from 0-10% of your visitors.

You are correct... I just figured someone would have developed this, but apparently if they have it's not well known.

I may try doing it manually using photoshop to convert the pdf pages to images, and then use a type of light box.

Thanks anyway.... good to talk to someone about this, even if it confirms that I'm not stupid for not finding what it is I'm looking for.

To be fair I must add that I gave the Kave plug in for secure pdf a second chance and got it working. It actually works perfectly. :) If you get the snippet addressed properly with the pdf url... ie https if that applies, www or not, etc. then it really does do what it says it does. You can even change the size of the embedded screen.

"Kave plugin": I think this means a plugin from JoomlaKave (https://extensions.joomla.org/extension/pdf-embedder/). I guess the "security" is handled by restricting access to the content (the article that uses this plugin) via Joomla's built-in ACL.

No. It's just paste document in iframe with blocking from printing and downloading options.
But you can open page code, search for ".pdf" and get link to file stored and download it.
So it's "protections" from dummies for dummies :D.

Try a different route maybe? How about looking to see if you can use the "hotlink protection" that some webhosts make available to block direct access? Usually used for images but you might be able to add .pdf to the filetypes and go from there?

As @mandville quite concisely phrased it, "not that I want to get involved" but ... this isn't really any of our business. If someone has a PDF file and they want to plonk it on the internet but remove the ability for people to download the file or print it, then it kind of defeats the purpose of sharing PDF files on the internet.

If someone has some [PDF-based] content but they want to stop people "saving" it in some other format (e.g. in printed form) then that's their business, I suppose. :pop

It's not a Joomla! issue as I've written before.
