Forget it. It is not possible to block these functions in a browser. The "best" you can do is to present your data in an image or Flash movie - inconceivable, slow, impractical, horrible to implement and also circumventable using OCR software.

If all else fails, users will simply make screen shots or key in the data manually.

If you present data to your users, you will have to live with the possibility that they can copy it. End of story.

Use legal threats to prevent your contents, not technical means.

Answer 3

To be honest, if you don't want people to use any information on your site, then you can't put it up there. If you stop them from being able to copy and paste the information, they'll still be able to take a screenshot of it, type it out and save the data that way. I know it's not the answer you're looking for, but that's just something to think about.

If you publish information online, you should clearly indicate your copyright claim on the page (or indicate the type of license you issue the content under). Please find and read the copyright law of your territory to understand what this does and doesn't allow - for example, in the UK there are provisions for making personal copies of copyrighted material and for using parts of copyrighted work for critical review or parody.

You can't stop people from copying the content on your page. You can make it more difficult for them to do - but this will have a negative impact on your page. Techniques such as preventing the left-click of the mouse, intercepting keyboard events or converting your entire article into images just make your website less usable.

If you have textual information on your website, I can re-type it even if you've stopped every other method of me copying the image. If you have an image and you've managed to lock out everything else, I can still do a screen-grab (not to mention the fact that my browser caches all the images in a temporary folder on my machine).

Your content-paranoia affects many people who set up a website - but the idea behind the Internet is that it is used for sharing information.

Just add the following code to the HEAD tag of your web page:
