Resumen de Secure provenance: protecting the genealogy of bits
Ragib Hasan, Radu Sion, Marianne Winslett
The ability to track the origin of information is essential in science, medicine commerce, and goverment. Applications such as digital rights protection, DNA testing, drug trials, corporate financial accounting, and national intelligence need to guarantee the integrity and authenticity of information as it flows between people and tasks. In this article, we describe what digital provenance means and how to provide strong integrity and confidentiality assurances for data provenance information. we present our provenance-aware system prototype that implements provenance tracking of data writes at the application layer, which makes it extremely easy to deploy. The proptotype is efficient: for typical real-life workloads, its runtime overhead does not to exceed 13% and is below3% for most workloads.
