Privacy in IoT Blockchains: with Big Data comes Big Responsibility

Abstract

This paper reviews current progress for privacy support in IoT blockchains. It starts by reviewing motivations for IoT architectures to incorporate blockchain capabilities and address privacy concerns. Currently available technological tools for enhancing and measuring privacy need enhancement for consumer use. Privacy concerns have moved beyond public relations angst and are emerging as regulatory imperatives. Regulations, privacy principles and impact statements move beyond traditional legal classifications of privacy violations to provide some guidance in the context of operating IoT blockchains. Legal and technical innovations have enabled new data ownership and control options. Operating IoT blockchains need adequate privacy patterns across the scope of privacy threats and the life cycles of the IoT blockchain.
