In smart grids, a smart meter communicates fine-grained information about a user's energy demand to the utility provider. A user's energy demand can be used to infer its private activities. Therefore, smart meters post a risk of violating privacy. This risk may be mitigated by using a rechargeable battery to obfuscate the user's demand. We investigate battery charging (and discharging) strategies...
In smart-metered systems, fine-grained time-series power usage data (load profile) is communicated from a user to the utility provider. The correlation of the load profile with a user's private activities leaves open the possibility of inference attacks. Using a rechargeable battery, the user can partially obscure its load profile and provide some protection to the private information using various...
