Photographs in digital form is much more difficult to preserve than in films and prints. While long-term digital preservation has long been studied, the methods are for organizations, and are far from realistic for personal use. This paper proposes a new scheme for life-time personal photo preservation. In the scheme called a chain of equipments, a long-term photo preservation policy is determined first, and then manufacturers supply tailored storage devices, called ring equipments, under the policy. Complicated tasks for migration is encapsulated in the ring equipments, and a chain of ring equipments preserves photo data for a long time. The specifications of ring equipments are constrained only by the policy, and then the manufacturers can avoid technology obsolescence. |
