How can I prevent PDF file on USB flash drive to being copy and paste either via right click or drag and drop copy to other device that is hookup to it like a PC? The file will be PDF, document file, JPG or some other image file, and some movie file etc.?

The scenario is the file will be needed to be just viewable to show people but they cannot copy any part of it out from it other than admin level that create/authorize full control of it. Example is like a person on a field trip is bring some presentation stored on USB flash drive and show it on field premise to showcase company stuff like brochure, PowerPoint, concept drawing, sales figure etc. but we do not allowed them to have those file on the USB drive to being able to copied off to client's PC or even their own home without authorization. Not even a phrase or JPG image from a particular document etc. Pretty much just view only mode.

    expire documents on a fixed date
    expire documents after a number of days
    expire documents after a number of views
    expire documents after a number of prints

    These options can also be used together so that you can enter say a number of days/views/prints and a fixed date and whatever occurs first causes the document to expire.  You might for example want a user to be able to use your documents for a 15 day trial period but those documents will expire on a fixed date regardless if the trial period is used or not.
