I have thousands of PPT presentations that I want to upload to a cloud based system.. I want to download different combinations of the files to different users and issue them stored on protected USBs with the files that they require. The data has to be encrypted within the USB.. The users need to be able to edit the files and then present them to their audiences. The user then modifies the presentation on the USB but they can't copy the files to anywhere or e-mail them to anyone as I don’t want someone to steal the content.. The user can take the USB to whatever machine is available in doing the presentation and it will work as long as they use the USB . Any solutions to how to deal with the above?
