The system comprises a memory device storing at least one document file that is based at least in part on a source document, which is an electronic version of a printed document. The system further comprises a distribution system programmed for: responding to requests from a client for delivery of a document file; retrieving a file copy from the memory device; assigning at least one right to the file copy, the right defining at least one action capable of being performed on at least a portion of the file copy; encrypting the file copy with a key based at least in part on the identity of the client and on the at least one right; and providing the encrypted file copy, with the associated key, to the client.

Abstract: A system, method, and computer readable medium having computer instructions provided thereon for enabling a computer to perform a method of simulating the effect of page turning including displaying a first image corresponding to a first side of a printed page on a display, where an aspect ratio of the display is automatically adjusted to an aspect ratio of the printed document, responding to user input to simulate turning the printed page to display a second image corresponding to a second side of the printed page and consecutively rendering individual representations of images of the page from a set of discrete representations one at a time to simulate the page being turned.
