TY - CONF T1 - Monitoring distributed collections using the Audit Control Environment (ACE) T2 - Proceedings of the 2010 Roadmap for Digital Preservation Interoperability Framework Workshop Y1 - 2010 A1 - Smorul,Michael A1 - Song,Sangchul A1 - JaJa, Joseph F. KW - digital KW - preservation AB - The Audit Control Environment (ACE) is a system which provides a scalable, auditable platform that actively monitors collections to ensure their integrity over the lifetime of an archive. It accomplishes this by using a small integrity token issued for each monitored item. This token is part of a larger externally auditable cryptographic system. We will describe how this system has been implemented for a set of applications designed to run in an archive or library environment. ACE has been used for almost two years by the Chronopolis Preservation Environment to monitor the integrity of collections replicated between the three independent archive partners. During this time, ACE has been expanded to better support the requirements of this distributed archive. We will describe how ACE has been used and expanded to support the Chronopolis preservation requirements. We conclude by discussing several future requirements for integrity monitoring that have been identified by users of ACE. These include securely monitoring remote data, monitoring offline data, and scaling monitoring activities in a way that does not impact the normal operational activity of an archive.

A primary requirement is the preservation of the authenticity and integrity of the digital records while simultaneously minimizing the cost of long-term storage, as the data is migrated onto successive generations of technology. The emergence of low-cost storage hardware has made it possible to implement innovative software systems that minimize risk of data loss and preserve authenticity and integrity. This paper describes software mechanisms in use in current persistent archives and presents an example based upon the NARA research prototype persistent archive.
