What I would be interested in is if there would be a way to encode data in an image that is robust to various kinds of jpeg/back/shrinking/enlarging transforms.

What I would be interested in is if there would be a way to encode data in an image that is robust to various kinds of jpeg/back/shrinking/enlarging transforms. This is really cool and useful but there's all kinds of normal processes that images go through that would destroy data hidden in an image this way. Perhaps something akin to parity or error correction data hidden somewhere else?
