Building Resilient Systems for the Department of Defense using Secure Data Provenance

Decision makers need timely and accurate data to make critical decisions. In many cases, that data is presented without evidence that it is trustworthy, leaving decision makers no choice but to blindly trust that the data is good. Modifications to the data can have a negative impact on the decision being made with few techniques to protect both the processing of the data and the data itself. Data provenance is a vital technology that provides decision makers with the evidence they need to make decisions based on good data, by tracking the history of ownership and processing of data as it moves through a system. In this talk, we describe the challenges of building resilient systems that leverage data provenance to protect data. We then detail our experiences with integrating data provenance into two different systems, and discuss the lessons-learned.
