The expression, "a photo cannot lie", could not be more debunked. A steady erosion of the barriers to producing fake but plausible visual media has occurred since the first development of photography at the end of the 19th century. The power and capability of tools and techniques available to bad actors have rapidly accelerated in recent decades and continue to do so at an increasing pace. Hence the need for robust mechanisms to ensure content provenance and authenticity have never been greater. The media industry was arguably caught on the back foot, lacking widely accredited mechanisms seeing near universal deployment across the entire production chain. Initiatives such as the Coalition for Content Provenance and Authenticity (C2PA) are making headway in addressing this problem. While some content manipulation is entirely unavoidable for numerous technical and aesthetic reasons, this presentation explores how can we might best accommodate these necessary, and sometimes complex, modifications.
