An option to do that without touching the RAW file could be: - calculate a cryptographic hash on the original RAW file when you download it - save the hash in a sidecar file, on an XMP tag which you know is carried over by all the programs you use This also has the nice property of warning you if your RAW file is corrupted in the future.
