This is a camera review. The specific camera is irrelevant; what's of interest is the Coalition for Content Provenance and Authenticity (C2PA). "Headed by large industry giants such as Adobe, Nikon, BBC, Intel, Microsoft, and Sony, to name a few, the C2PA has devised a way to securely embed any information relevant to the altering of images within the EXIF data of said files. These changes are protected by hash codes and certified digital signatures." We've mentioned hash codes here before; they are what's used to authenticate content in IPFS and in blockchains. Here, they provide some assurance that the image hasn't been tampered with between production and viewing.
