I have a problem regarding json web service security. I tried to developed a sample web application using json webservice,but the problem is the url was exposed on the client side.So from there,anybody can make a program and call the service for a thousand times. Please take note, that the web service will be using for a registration page, in which checks if the user was exist on the database.So there is no authentication happened on this process.

What are the approach to secure the calling of the exposed web service?
