Creating a Secure Digital Archive
Digital media poses a challenge on many fronts, from long term data integrity to custodianship. We have completed the first steps in an ongiong proccess to ensure the data integrity of our digital archive over the next many generations. If you obtain a copy of a video purported to be from our corpus, our tools will support you in verifying that the video is indeed authentic.
On January 27, 2009, The New York Times published an article on our verification process in the science section (page D3). The graphic from that article is reproduced below (read the full article).
