About five years ago, when encryption was the buzz, a number of digital
studios started doing this type of image hiding, and especially the use of
near-replications of well-known fine art images. The art and science of
communicating in a way which hides the existence of the communication is
used in a lot of modes. Videomakers uses encryption similar to
watermarking, but I guess it was called toastermarking scrumbling.
Re digital images, I'd like to see 2-way interactives that invite third
party encryption images and send then send them back - encrypt and decrypt
back.
