[R] FaceSigns: Semi-Fragile Neural Watermarks for Media Authentication and Countering Deepfakes

Hi Everyone!

We have released the preprint and google colab demo for our paper FaceSigns. FaceSigns embeds a secret bit-string as a semi-fragile watermark in the image pixels. The message is recoverable if benign image operations such as color/contrast adjustment, JPEG compression, Instagram filters are applied. However, the message cannot be decoded if the image is facially tampered (eg. DeepFake manipulation) . This selective fragility allows reliable detection of DeepFake manipulations applied on images signed using FaceSigns.
