SPAINChain: Security, Privacy, and Ambient Intelligence in Negotiation Between IOT and Blockchain

Vulnerability in Internet-of-Things (IoT) necessitates the existence of a safeguard for both security and privacy without sacrificing “smartness” of the environment, or its Ambient Intelligence in scientific terms. Blockchains, underpinning crypto-currency, could be the remedy for this vulnerability. This paper quickly overviews security, privacy, Ambient Intelligence, and the use of Blockchain as a safeguard for IOT, before proposing and evaluating SPAINChain:Security, Privacy, and Ambient Intelligence in Negotiation between IOT and Blockchain. IOT-Blockchain mapping is proven to be feasible. The gamut of blockchain is based on a new concept called solidus. Solidus is basically the sum of blockchain favorability dimensions, adjusted by preference of blockchain type.
