Blockchain-based Model for Trustworthy Shared Internet of Things Device Management

In a sharing economy, the management of shared Internet of Things (IoT) devices is of primary concern. For trustworthy management, accountability regarding the shared devices must be guaranteed. Blockchain, which stores data history securely, could be one solution. This study proposes a blockchain-based model for the management of shared IoT devices. In this model, when a change event occurs in the device, the description is written on the blockchain. With the blockchain, a user or manager can verify the current status of the shared device.
