Show HN: Owoa – Image watermarking resistant to camera capture

wodoshio Wednesday, February 18, 2026

My friends and I built Owoa to solve a specific problem in digital rights management: the "analog hole."

Traditional steganography and watermarking usually rely on LSB (Least Significant Bit) modifications or fragile metadata. These methods are instantly defeated the moment a user takes a physical photo of their monitor with a smartphone. The moiré patterns, sensor noise, and lens distortion destroy the digital signal.

Instead of hiding data in pixels, Owoa uses generative AI to create unique variants of an image by subtly modifying background elements (textures, foliage, unstructured patterns).

Because the "data" is now part of the actual visual composition of the image, it is much more robust. In our testing, the attribution survives:

Heavy JPEG compression and resizing.

Aggressive cropping.

Physical photos of 1080p/4K screens taken with mid-range smartphones.

We've just launched a Owoa Playground and are looking for technical feedback on the robustness of this approach compared to traditional robust watermarking.

We're giving 10 free credits to anyone who joins the waitlist to test the engine. I'd love to hear how you'd try to break this.
