Abstract (en)
[origin: WO0205556A1] The invention includes an interactive Internet, television or media scrambler and decoding mechanism. A fixed or variable encrypted image is printed onto a clear or translucent film and is placed in front of a broadcasted descrambler to decode the hidden image. An oscillating, zooming image is projected on the monitor or television screen, which aligns in proper phase with the scrambled image, thereby disclosing the hidden image. The scrambled image and descrambler can also be reversed to maintain control of the hidden image at the website or television transmission site. Conventional inks may be used with sufficient scuff resistance to create the printed image, or a primer may be applied for added protection. The oscillating, zooming image provides a means for uniformity between equipment, processors, software and browsers.
