You Can't Protect Your Page Content
Thursday November 12, 2009
Web pages are open source and there is nothing you can do to protect the content
Every so often I receive emails about my Image Protection JavaScript that places the image in the background of a table with a transparent image in front of it. All of these emails have pointed out that there are other ways to obtain the image and that it is not really protected. In fact there is no way to stop people obtaining the content of your web page since they have it already on their computer when they view your page. The same is true even if you use JavaScript to encrypt your page source since your visitors all have something that can decrypt it for them (called a web browser). In fact applying something as simple as a no right click script (which is the least effective way to try to protect anything) will just drive visitors away from your site. Any of these techniques may stop newbie web users from taking your code and images (and will do so at least as effectively as much longer codes and more expensive solutions found elsewhere on the web) but nothing will prevent someone who knows how the web works from obtaining whatever they want from your site.
