ACE (Auditing Control Environment) is a prototype system that incorporates a new methodology to address the integrity of long term archives using rigorous cryptographic techniques. ACE continuously audits the contents of the various objects according to the policy set by the archive, and provides mechanisms for an independent third-party auditor to certify the integrity of any object.

Our approach will allow an independent auditor to verify the integrity of every version of an archived digital object as well as link the current version to the original form of the object when it was ingested into the archive. Also, ACE is very cost effective and scalable while making no assumptions about the archive architecture.

ACE consists of two components, the first an Audit Manager(AM) that checks files locally to ensure they have not been compromised. The second part, the Integrity Management Service (IMS), issues tokens that the AM can use to verify that its local store of file digests has not been tampered with.

Anyone wishing to audit their files with ACE only needs to install an Audit Manager locally to manage their files. The ADAPT project runs a publically available IMS at ims.umiacs.umd.edu that any group may freely use.
