I do like the idea of storing it steganographically, which also serves as a watermark.
But it requires a ton of redundancy and error correction, perhaps enough to survive a few rounds of not-too-lossy reencoding. I dunno how much bandwidth is available before it damages the image.
- kuberwastaken 1y agoGreat point, I like that idea too: I’ll definitely look into adding redundancy and testing how much re-encoding it can realistically handle without noticeable image damage. Thanks for taking the time to check it out :)
- techjamie 1y agoI wonder how practical it'd be to stratanagraphically hide a QR code in an image and it be retained through rounds of JPEG compression. It could be represented with a single bit per pixel and would inherently have some resistance to corruption. The real limitation would be bandwidth.
