As increasing amounts of valuable information are produced and persist digitally, the ability to determine the origin of data becomes important. In science, medicine, commerce, and government, data provenance tracking is essential for rights protection, regulatory compliance, management of intelligence and medical data, and authentication of information as it flows through workplace tasks. While significant research has been conducted in this area, the associated security and privacy issues have not been explored, leaving provenance information vulnerable to illicit alteration as it passes through untrusted environments.

In this talk, we show how to provide strong integrity and confidentiality assurances for data provenance information in an untrusted distributed environment. We describe our provenance-aware system prototype that implements provenance tracking of data writes at the application layer, which makes it extremely easy to deploy. We present empirical results that show that, for typical real-life workloads, the run-time overhead of our approach to recording provenance with confidentiality and integrity guarantees ranges from 1% - 13%.

This talk is based on a paper to be presented in USENIX FAST 2009.


Ragib Hasan is a Ph.D. candidate at the Department of Computer Science, University of Illinois at Urbana-Champaign, working with Prof. Marianne Winslett. He is also co-advised by Prof. Radu Sion of Stony Brook University. His dissertation focuses on storage security in general, and secure provenance, tamper-evident data storage, and term-immutable databases in particular. His other research interests include trust management, remembrance-capable systems, and computer- supported collaborative knowledge-generation.

He graduated summa-cum-laude, with a B.S. in Computer Science and Engineering, from Bangladesh University of Engineering and Technology in 2003. He received his M.S. in Computer Science from the University of Illinois at Urbana-Champaign in 2005.

He is the recipient of the Chancellor Award and the Sharfuddin Gold Medal from Bangladesh University of Engineering and Technology.
