💡 Lights vs. Lies
When deepfakes look just like reality, Cornell came up with a clever hack — hide watermarks in the light itself. Their NCI tech makes lamps and screens flicker invisibly with a unique code. Eyes can’t see it, cameras record it.
When checked, a computer decodes the light pattern and matches it to the original. If it’s a fake — the image “breaks” with black gaps. Add unique codes for each light source, and forging becomes nearly impossible.
Oh, and it works with any camera — from a Hollywood rig to your old phone. The future of fighting fakes might just shine right in our faces.
