A Privacy-Preserving Concurrent Query-Answering Protocol for Selfish Knowledge-Based Systems
Pinata Winoto · 2018
This paper shows a distributed implementation of concurrent query-answering protocol among agents with objective to answer their individual query by means of logical inference from the integrated private knowledge bases (KBs) owned by each agent. Agents may misreport some contents of their KB as long as it will not affect the correctness of the answer they are looking, and such a misreport is not verifiable by others. Our proposed protocol is intended to prevent agents from misreporting and, more importantly, to protect their privacy, so that all answers obtained from the integrated KB are truthfully derived and no party knows the knowledge of individual others other than its own.
