Secure And Privacy-Preserving Crowd Sensing Using Smart Contracts: Issue And Solution

Abstract

The advent of Block chain and smart contracts is empowering many technologies and systems to automate commerce and facilitate the exchange, tracking and the provision of goods, data and services in a reliable and auditable way. Crowd sensing systems is one type of systems that have been receiving a lot of attention in the past few years. In crowd sensing systems consumer devices such as mobile phones and Internet of Things devices are used to deploy wide-scale sensor networks. We identify some of the major security and privacy issues associated with the development of crowd sensing systems based on smart contracts and Block chain. We also explore possible solutions that can address major security concerns with these systems.
