Data Provenance architecture to support Information Assurance in a Multi-Level Secure Environment

摘要

We describe a framework for capturing Data Provenance information to support Information Assurance attributes like Availability, Authentication, Confidentiality, Integrity and Non-Repudiation. Our approach is applicable to Multi-Level Secure systems where it is not always possible to directly provide data source and data transformation information. We achieve this by combining the subjective and objective trust in data as a “Figure of Merit” value that can cross security boundaries.
