I am using iframe to load a pdf file from a temporary location , which looks as shown below

```
<iframe id="myPDF" width="100%" height="100%" src="Config\Temp\tmp_report_0.pdf"></iframe>

```

this will load up a pdf file to browser window, inside the iframe.
My question is how can i hide this 'src' value from being visible to user when they right click and select 'view source' from browser.

The intention is here to enrcypt/hide the 'src' value from users.
Any suggestions?
