title: How to hide real URL with Google Cloud Storage?
body: <p>Scenario: I place some files on Google web storage.</p>
  
  <p>And I want only paid users can download this file. So my question is, how to hide this file from paid user to prevent them from sharing this URL with other unpaid users.</p>
  
  <p>So, is there a way to hide the real file location? Single-use or time-restricted URLs or any other?</p>
  
  <p>May be hiding URL is possible with other CDN providers - MIcrosoft Azure Storage or Amazon S3?</p>
