Hide URL of the Document when using Google Document Viewer with IFRAME

<iframe src="http://docs.google.com/viewer?url=filename&embedded=true" style="width:600px; height:600px;margin-left:20px;" frameborder="0"></iframe>

i m using above code to show our document online.

But when we inspect element it is showing url of file which we dont't want.

it is possible to hide this url or any other alternate to show our document to user without exposing our physical file path.
