ABSTRACT:
A scrambled document or image generating method first divides a page of digitized electronic document into multiple segments arranged in a first order. The digitized electronic document is scrambled in a pseudo-random manner using a scrambling algorithm to produce a scrambled document in digitized electronic form, which can be used to print out a hard copy or visually examined on a display. In one embodiment, the scrambling algorithm receives as input one or more keys, which can be entered through a keyboard, or read from a storage medium. Descrambling of a scrambled digitized electronic document is accomplished by the original positions of the scrambled segments. The scrambled document in its digitized electronic form, or in its physically viewable form retain all information of the original image, and can therefore each be used as a source of the scrambled image.
