Preventing copy

I have several pages that show a frame in which a doc of google is included. How can I prevent it from being copied?
Thanks

Hi, Pedro.

Even if you get answers, there are ways to bypass copy restrictions (e.g., I remember in the '90s that Lotus Notes had a feature whereby you could prevent someone from copying/forwarding an e-mail; it was easily bypassed by pressing [PrtScn] on the keyboard and pasting the clipboard content into some application (e.g., Paint, MS Word, etc.).

you can put a transparent box over it, that way the user can not select the text under the box and copy it

Wonderful thanks

You can still select the text if you click above or below it. Is there another solution for this?
