Sure, why not make the art itself the lock? Embed a tiny cryptographic key in the pixel matrix, so any alteration changes the hash. Then the canvas can check its own integrity on each render, and if it detects a tweak it could trigger an adaptive response—like shifting colors or emitting a warning. Think of it as a living, breathing piece that refuses to be a static, hackable image. Just watch out for the extra compute; those self‑protecting pixels can get pretty demanding on a GPU.
