Competitive Privacy in the Smart Grid: An Information-theoretic Approach
Lalitha Sankar, Soummya Kar, Ravi Tandon +1
Advances in sensing and communication capabilities as well as power industry deregulation are driving the need for distributed state estimation in the smart grid at the level of th…
Smart Meter Privacy: A Utility-Privacy Framework
S. Raj Rajagopalan, Lalitha Sankar, Soheil Mohajer +1
End-user privacy in smart meter measurements is a well-known challenge in the smart grid. The solutions offered thus far have been tied to specific technologies such as batteries o…
Discriminatory Lossy Source Coding: Side Information Privacy
Ravi Tandon, Lalitha Sankar, H. Vincent Poor
A lossy source coding problem is studied in which a source encoder communicates with two decoders, one with and one without correlated side information with an additional constrain…
Multi-User Privacy: The Gray-Wyner System and Generalized Common Information
Ravi Tandon, Lalitha Sankar, H. Vincent Poor
The problem of preserving privacy when a multivariate source is required to be revealed partially to multiple users is modeled as a Gray-Wyner source coding problem with K correlat…
Utility-Privacy Tradeoff in Databases: An Information-theoretic Approach
Lalitha Sankar, S. Raj Rajagopalan, H. Vincent Poor
Ensuring the usefulness of electronic data sources while providing necessary privacy guarantees is an important unsolved problem. This problem drives the need for an analytical fra…
