Is there any good article/paper that describes how it actually works or is implemented not just in high-level and hand-waving terms?

    Yeah Hacker Factor's multi-post critiques are where I first saw it analyzed. For reference they run the popular fotoforensics.com image analysis site. They also have scathing critique (eg [1]) about the Adobe-led C2PA digital provenance signing, having themselves been part of various groups that seek solutions to the provenance problem.

  There tends to be more information under the search term "perceptual hashing"
