How to set a confluence page viewable but can not be copied?

[xinan liu]

As the title says, how to set a page which can only be viewed online by users but can not be copied? Because we do not want some one to copy the page and leak the message.

Can confluence do this? Thanks very much!

Nothing can do this - it's always possible to scrape a web site for content.  Your browser has the information needed to render the content, so you've got a copy already.

Well, can Confluence do that set a pdf can be read online but can not be downloaded? Or how to set uers can not export the page to pdf? We just want to make the risk of leaking to a low level. Wahtever way can do a liitle more advantage will help me. Thanks!

No. You're not quite grasping how computers work. For your browser to display something, it *has to download it* so it can read and display it. If a user can see something, they already have a copy of it. The only way you can stop them having a copy is not to allow them to see it at all. You can make it mildly inconvenient by blocking easy copies, but you can't stop them copying it.

You can turn off pdf exports by disabling the modules that provide them, but that won't stop them using "print to pdf" locally, or "save page as" or "export to other format".

How to disable the modules that provide pdf export? Can you tell me the way to do it, thanks! Some website has the way to forbidden users to copy or export their web pages, just like <noscript> <iframe src="*.htm"></iframe> </noscript> <script language="Javascript"> document.oncontextmenu=new Function("event.returnValue=false"); document.onselectstart=new Function("event.returnValue=false"); </script> but I edit the page by using plugin Source Editor, I can not add this code into the page, when I add it and save, the code will disappear. Is that confluence page does not support javascript?

There are no websites that have forbidden copy or export - it cannot be done. If you want to disable exports, go into manage addons and find the addons which provide the various views, you should find there are modules that provide the links and functions. Disable the module and the option will disappear.

This is impossible.

If the information is show in a display, anyone take a phone and take a photo of it and share that.
