Integrated image scrambling and descrambling
First Claim

1. A unit comprising:
- (a) a substrate;
(b) a scrambled image printed onto the substrate, wherein the image has been scrambled by suppressing from view at least part of the image, by introducing to the image meaningless background imagery, or by a combination of both; and
(c) a decoding mechanism printed onto the substrate, wherein the decoding mechanism at least partially fills in the part of the image suppressed from view, at least partially suppresses from view the meaningless background imagery, or does both, wherein the decoding mechanism is not initially apparent but which subsequently can be exposed to decode the scrambled image.

Abstract
A method for printing a scrambled image and decoding mechanism in registration one on top of the other. The decoding mechanism is not immediately apparent upon inspection. A person decodes the scrambled image by exposing the decoding mechanism.

14. A method of encoding information in a substrate comprising:
-
(a) printing a scrambled image onto a substrate, wherein the image has been scrambled by suppressing from view at least part of the image, by introducing to the image meaningless background imagery, or by a combination of both; and (b) printing onto the substrate a decoding mechanism that at least partially fills in the part of the image suppressed from view, that at least partially suppresses from view the meaningless background imagery, or that does both, wherein the decoding mechanism is not initially apparent but which subsequently can be exposed to decode the scrambled image.
