Abstract

In this chapter, the author first work over the integration of differential privacy and blockchain in real-time smart metering scenario. Afterwards, we carried out performance evaluation of four variants of differential privacy in the proposed blockchain-based smart metering scenario. The performance evaluation section of this chapter demonstrates that each privacy -preserving mechanism adds differently depending upon the selected privacy parameters and the input data. However, in the case of high peak values the Geometric mechanism surpasses other noise addition variants, although, in case of low peak values in metre reading, the Laplace mechanism performs better at e = 0.01. As a part of future work, we are working over the integration of differential privacy and blockchain in other cyber-physical systems scenarios.
