A Blockchain-Based Approach to Improving Smart Home Security With Situation-Aware Access Control

Recent advances in information technologies have made great improvements to smart homes with various services, but the security of smart homes remains a critical issue. Traditional security measures often overlook the importance of data and lack efficient tracking of incidents, and complicating access management across various user groups. In this paper, an effective approach to improving the security of smart homes based on blockchain and using situation-aware access control is presented. Specifically, this approach provides improved access control to securely store and protect transaction data, including residents’ personal information, behavior patterns, and devices in smart homes, ensuring robust data protection and increased transparency and auditability. This approach is compared to existing approaches and its major advantages are discussed.
