I am trying to identify a means of document control for our department that allows distribution to department personnel of sensitive documents that both protects the documents from redistribution or copying but also allows for airborne accessibility.

In other words, we want to be able to distribute a document such as the Policy and Operations Manual that will allow personnel to place a document on their iPad for reference but not be able to redistribute, copy, or print it.

Does anyone have some suggestions of programs or apps that allow this?

Thanks in advance.
