Poster Abstract: Preserving IoT Privacy in Sharing Economy Via Smart Contract

Abstract

The phenomenal growth of Internet-services has created a vibrant new domain for sharing economy. Millions of users around the world share personal services and possessions with others - often complete strangers. Such sharing schemes also increase the risk of violation of one's informational and physical privacy. Strangers often have to trust each other with their privacy (e.g. a surveillance camera in an Airbnb room). However, very little research has been devoted to investigate privacy in sharing economy. In this paper, we explore the privacy concerns associated with contractual renting or leasing of IoT devices-enabled home. We propose a methodology to eliminate privacy threats from IoT-enabled telematics devices in a smart home via blockchain-based smart contract. For the purpose of illustration, we focus on how we can circumvent the privacy threat from indoor surveillance IP cameras in a smart home-sharing economy.
