Blockchain Integration in Smart Home
Introduction


        Smart Home
•Smart home allows home appliances (such as television, air conditioner and refrigerator) to be
connected to the internet and providing innovative and smart service to humans.
•
•We can remotely control our home devices over the internet and information about our home can be
directly reach to our smartphone.

          Parental Controls
•Blockchain mechanism can be used to control children at home.
•Parent can encourage good behaviors and discourage bad behaviors of children via tokens
transferred via blockchain network.

 Blockchain Use in Home Automation

•Blockchain mechanism can be used to control children by their parent.
•Parent can encourage good behaviors and discourage bad behaviors of children via tokens
transferred via blockchain network.
•
•Blockchain is capable of controlling the secure access and efficient data sharing in smart home
systems.

Contribution
•
•We propose a Blockchain-based Access Control solution, named as BAC, which controls the access to
smart home devices and ensures secure communications between the IoT devices and the householders

•
•In order to increase Blockchain efficiency for smart home IoT network, the Blockchain platform
will create two kinds of agents: (1) a static agent, and (2) a mobile agent

•

           Architecture of Blockchain Agents-based Model
•Static Agent is a static agent that will be implemented in each peer device of the Blockchain.
Once the peer device receives a transaction such as a activity request, The peer device will use
the static agent to verify and check the received transaction.
•
•Mobile Agent is the agent that is created by the householder managers to control access to their
household devices, as well as monitoring and detecting inappropriate using of household devices.

                                       Conclusion



                                      Future Directions
•We first plan to conduct more experiments with various real-world IoT applications.
•A user study will be conducted in a real-world smart home environment, and we will also intend to
investigate the interoperability and the cost of implementing our solution compared to other
solutions.
