A crucial aspect of certain applications such as the ones pertaining to Intelligence domain or Health-care, is to manage and protect sensitive information effectively and efficiently. In this paper, the authors propose a tagging mechanism to track the flow of sensitive or valuable information in a provenance graph and automate the process of document classification. When provenance is initially recorded, the documents of a provenance graph are assumed to be annotated with tags representing their sensitivity or priority.
