For a variety of reasons, (maybe not all of them good!) we are about to
move from microfilming raw data to scanning the data to optical disc. We
need to be able to certify that the image is a true copy and in the past,
we merely made the first image on the microfilm the "authentication" page.
This meant that if necessary an auditor or inspector could hold the
microfilm in his hand and look at the authentication page and the
photographic image on the same film. (Our auditors and inspectors are hard
to please!!!). How have people coped with authentication of images on
optical disc? And how do you know that after a certain period of time or as
a result of migration, the image can still be authenticated as a true
copy? Any information would be appreciated.
