The World Health Organization (WHO) guidelines for monitoring the effectiveness of HIV treatment in resource-limited settings (RLS) are mostly based on clinical and immunological markers (e.g., CD4 cell counts). Recent research indicates that the guidelines are inadequate and can...

A Randomized Response Model For Privacy Preserving Smart Metering.

IEEE transactions on smart grid

Wang S, Cui L, Que J, Choi DH, Jiang X, Cheng S, Xie L.
PMID: 23243488
IEEE Trans Smart Grid. 2012 Sep;3(2):1317-1324. doi: 10.1109/tsg.2012.2192487.

The adoption of smart meters may bring new privacy concerns to the general public. Given the fact that metering data of individual homes/factories is accumulated every 15 minutes, it is possible to infer the pattern of electricity consumption of...
