A rechargeable battery may be used to partially protect the privacy of information contained in a household's electrical load profile. We represent the system as a finite state model to make tractable the computation of the rate of information leakage. Specifically, we use a trellis algorithm to estimate the mutual information rate between the battery's input and output loads. We show that stochastic...
Biometric secret-key binding inherently requires signal processing and error correction schemes due to noisy measurement readings. Two previously proposed strategies, Quantization Index Modulation (QIM) andWyner-Ziv (WZ) coding, are studied in the context of biometric key binding. We characterize the tradeoff between key rateleakage and key rate-reconstruction distortion, showing that while WZ coding...
