The Internet of Things (IoT) has dramatically developed in recent years. Massive data is generated and collected with the deployment of various IoT devices, which contains the considerable value in many fields, such as smart healthcare and transportation. However, due to constrained resources and distributed architecture, IoT systems are also suffering from severe security and trust problems. With public consensus, blockchain is a promising technique to deal with the above problems in IoT systems. This emerging paradigm, known as the blockchain-empowered Internet of Things, can provide multiple desirable characteristics to IoT systems, such as data integrity and traceability. Recently, the blockchain-empowered Internet of Things has attracted extensive attention from both academia and industrial communities.
Despite the great success, the inherent properties (such as transparency and immutability) of the blockchain-empowered Internet of Things also introduce new security and privacy concerns to users, especially considering various data regulations, such as GDPR. For example, transparency means that the data is accessible to all users, violating the right to restriction of processing of users. Also, the immutability of blockchain hinders the right to be forgotten, which may lead to the spread of improper data. Currently, there is a great need to make a balance between these challenging problems and the advantages of the blockchain-empowered Internet of Things.
