title: Is it possible to protect our documents from getting copied using HTML 5 or general Web technologies?
body: <p>I want to develop a Web App for Mobile users, which will provide users with documents for users to view. I want to ensure that the documents once downloaded to temp folder needs to be deleted once user closes the window. Is there any option for this in HTML 5?</p>
  
  <p>Is there any provision to disable copy/paste options for when browser shows the specific pdf documents or MS office documents?</p>
  
  <p><strong>UPDATE1:</strong>
  Two things I need to know if possible:</p>
  
  <ol>
  <li>Ability to delete files through an API</li>
  <li>Disable copy, paste option through Browser for Documents. (might seem like a fantasy)</li>
  </ol>
