I have http://example.com/index.html, which from within the HTML uses JavaScript to call a web services at http://example.com/json/?a=...&b=...

The web service returns to index.html a JSON array of information to then be displayed on index.html.

Since anyone can view the source code for index.html and see how I'm calling the JSON web services (http://example.com/json/), how do I prevent people from calling my JSON web service directly?

Since the web service is essentially an open read into my database, I don't want people to abuse the web service and start DoS my server, fetching more information than they should, etc..
