I made a beautifaul power point presentation. It's stored on a USB drive. But my problem is the following thing: I need to speak somewhere, and I have to give my USB-stick to them, so they can 'set everything ready' for the presantation. Afcourse, while they will set it ready, they will copy my presantation.... Is there a way that they can only read my presantation, not copy it to the drive
