Is there an other way to protect my document agains downloading?

[try67 · Accepted solution]

No. In order for a PDF file to be viewable it has to be downloaded first.

You can protect a file from being opened by unauthorized people, but that will require using DRM technology, which is ​very​ expensive.

So, the only way to prefend agains plagiarism is to sign the document, put an watermark on it and mention it in your Terms and Conditions?

[try67]

Yes, although if someone is willing enough they could get around all of that.
