Best way to protect your content from copy & paste

Anyone knows trick to prevent copy & paste?

i 've got a few,,but not too effective

1) disable right click (not effective and not that useful, still able to do ctrl + c
2) Use css div to put a transparent image over area of content (hard to do)

Do you have anyother tricks?

 

Past the disable of the right click I wouldn't really worry about it. Nothing much more you can do.

 

I just to search for protecting source programs and belive there is no way to protect page 100%. Alwaus there is a way to steal.
Maybe you shoud try www.copyscape.com
Just byt button page protected by copyscape and you can check if someone copyed your page om their site just by entering url.
