An Optimized Privacy-Utility Trade-off Framework for Differentially Private Data Sharing in Blockchain-based Internet of Things. (arXiv:2212.00128v1 [cs.CR])
cs.CR updates on arXiv.org arxiv.org
Differential private (DP) query and response mechanisms have been widely
adopted in various applications based on Internet of Things (IoT) to leverage
variety of benefits through data analysis. The protection of sensitive
information is achieved through the addition of noise into the query response
which hides the individual records in a dataset. However, the noise addition
negatively impacts the accuracy which gives rise to privacy-utility trade-off.
Moreover, the DP budget or cost $\epsilon$ is often fixed and it accumulates
due …
