A Content Integrity Service For Long-Term Digital Archives

We present a content integrity service for long-lived digital documents, especially for objects stored in long-term digital archives. The goal of the service is to demonstrate that information in the archive is authentic and has not been unintentionally or maliciously altered, even after its bit representation in the archive has undergone one or more transformations. We describe our design for an efficient, secure service that achieves this, and our implementation of the first prototype of such a service that we built for HP's Digital Media Platform. Our solution relies on one-way hashing and digital time-stamping procedures.

Our service applies not only to transformations to archival content such as format changes, but also to the introduction of new cryptographic primitives, such as new one-way hash functions. This feature is absolutely necessary in the design of an integrity-preserving system that is meant to endure for decades.

  • The IS&T (digital) Archiving Conference offers a unique opportunity for imaging scientists and those working in the cultural heritage community (curators, archivists, librarians, photographers etc) from around the world to come together to discuss the most pressing issues related to the digital preservation and stewardship of hardcopy, and other cultural heritage documents and objects. Authors come from museums, archives, libraries, government institutions, industry and academia. Cutting edge topics related to multispectral and 3D imaging, as well as best practices for workflow, sharing, standards, and asset/collection management and dissemination are explored in papers presented at this annual, international event.

    Please note: For purposes of its Digital Library content, IS&T defines Open Access as papers that will be downloadable in their entirety for free in pertuity. Copyright restrictions on papers vary; see individual paper for details.
