I'm not a forensics person but I am interested in how an image is created and how watermarks work. While futzing with GIMP one day I came across fourier analysis and found that the images on the giant aggregator sites like getty and/or alamy put (what I believe) are spectral watermarks in their images.

These spectral watermarks are not visible and are pretty durable to manipulation.

Fascinating stuff!
