Developer says he built an open alternative to SynthID

A commenter describes creating an imperceptible, tamper-resistant watermarking tool intended to be open-sourced, positioned as a transparent, independently-decodable alternative to closed systems like SynthID.
“I created an imperceptible tamper-resistent watermarking tool intended to be open-sourced, where the watermark can be decoded independently and steganographic aspects are impossible as the algorithm is transparent so nothing can be hidden.”

The word choice example is cool. I wonder if it really works dependably. I'm sure many many exerpts in posts and books have those same 8 bits - you'd need a lot more bits - but the more you add the more strange your writing style might become.Like it choose between "winding" and "curving" but there are many uses of curving that probably can't be…

Out of frustration with SynthID being closed-source with weird dubious ways to verify if an image has the watermark, I created an imperceptible tamper-resistent watermarking tool intended to be open-sourced, where the watermark can be decoded independently and steganographic aspects are impossible as the algorithm is transparent so nothing can be…

> A watermark is a visible mark embedded in a physical or digital medium to verify authenticity or assert ownership.We also recently had this with LG spy-TVs. Cars here in the EU also spy on people, allegedly to show how alert they are. Perhaps they sneakily upload that information somewhere ... Facebook also has the spy-glasses now. People…
