2013 IEEE Security and Privacy Workshops
The Probabilistic Provenance Graph

Previous provenance models have assumed that there is complete certainty in the provenance rela- tionships. But what if this assumption does not hold? In this work, we propose a probabilistic provenance graph (PPG) model to characterize scenarios where provenance relationships are uncertain. We describe two motivating examples. The first example demon- strates the uncertainty associated with the prove- nance of an email. The second example demonstrates and characterizes the uncertainty associated with the provenance of statements in documents.
