embed Tag - disable controls for pdf view

i'd like to have chrome's pdf viewer implemented to my application which runs in kiosk mode. Therefore i'm using this simple embed tag.

<embed src="my/path/to/this.pdf" width="100%" height="800px" >

→ To prevent the user from downloading / printing the shown document i'd like to disable the controls here.

It seems, that there's no appropriate html attribute to achieve that - maybe a chrome internal setting for the controls to configure/disable/hide?

Thanks for your help
