Abstract
This paper
analyzes the requirements and describes a system designed for retaining records
and ensuring their legibility, interpretability, availability, and provable
authenticity over long periods of time. In general, information preservation is
accomplished not by any one single technique, but by avoiding all of the many
possible events that might cause loss. The focus of the system is on preservation
in the 10 to 100 year time span—a long enough period such that many difficult
problems are known and can be addressed, but not unimaginable in terms of the
longevity of computer systems and technology.
The general
approach focuses on eliminating single points of failure - single elements
whose failure would cause information loss - combined with active detection and
repair in the event of failure. Techniques employed include secret sharing,
aggressive "preemptive" format conversion, metadata acquisition,
active monitoring, and using standard Internet storage services in a novel way.
Conclusion
One problem to
be solved before individuals and businesses will be comfortable with using
all-digital documents, photographs and other electronic media is to provide
assurances that the content is as safe, or safer, than their physical
counterparts. We believe our work makes significant steps towards addressing
major problems of long-term digital records by using a multi-faceted approach
to guard against the many problems which might otherwise arise.
