title: Securing azure media services downloadable content
body: <p>I am using Azure Media Services for hosting video content which can the user can then download to his device. The solution I have found is to create a SAS url which is valid for a short duration. But even with this approach, a third user, say a person trying to steal the content, can download the content if he has the url and make a request within ths SAS url validity time. </p>
  
  <p>Is there any other way supported by Azure Media Services, using which, even after download, only that user can view the file for which it is meant ?</p>
