a simple question: which PDF component shall I install?
-
Cannot prevent someone from taking a picture 🖼️ of the screen from their mobile camera 📸. And then using OCR to convert the image to text. Isn't it? Addendum: Other than the Coca Cola formula, is there anything which has been protected without getting leaked? As individuals, we perhaps don't have the financial strength to protect our so-called intellectual property.

If you don't like, that somebody can have a copy in what format ever (pdf, screen shots, whatelse), then don't publish it... :doh:

I have written some useful articles that may be valuable to some readers. I want to post them on my website for users to read and don't want them to download to local computers. what kind of PDF component to be installed on server side? just a PDF viewer server component? Thanks a million for any thought!

You do realize that as long as it's published you can't stop that, regardless of format? I understand if someone doesn't want to be plagiarized. It's happened to me and that sucks. But, asking someone not to save it... why, you wanna show them new adds or something? If you're worried about squeezing a dollar out of someone then put it behind a paywall. Keep in mind though, the scientific community doesn't take too kind to the average antics people play when it comes to extorsion, money, etc. Which is what this sounds like if plan on making sure nobody can save your content.

I generally use print screen for that.
You can also quickly disable JavaScript, after the page loads/renders, in DevTools to save the image. Or intercept the request. Or, there are a ton of ways...

On my site I have a lot of photos and the way I restricted users from copying is by capturing the right click and displaying a popup that informs the user if they want a copy to contact me. But there are always ways to get the material, maybe not in the form they want but they can get it.

Screwing with someone's browser experience is bad juju. It's no better than endless popups. It'll only prevent non-techy users anyway. If you're really that worried about it, you're better off watermarking the image.

I do watermark, but I'm not really worried about them. The techies will get them no matter what.

my website is member only. so when you read it, I will put your name on top of the article. so if you take pictures, your name will be visible.

In addition to the above replies, you should note that PDF is not a "read-only" format. Many tools are available to unpick PDFs into an editable form. You don't need a "viewer server" component. Just publish the PDF and browsers know what to do.
