title: secured web service php/json
body: <p>I'm currently creating an admin platform with a lot of website, these sites can publish and get data from the admin platform.</p>
  
  <p>There is a way to secure this and only accept publish/get from these sites ?</p>
  
  <p><strong>EDIT</strong></p>
  
  <p>Actualy I use some ajax scripts with JQuery in a test website. And it's not safe at all.</p>
