A blockchain-based deployment framework for protecting building design intellectual property rights in collaborative digital environments

Protecting intellectual property rights (IPR) in the architecture, engineering, and construction (AEC) industry is a long-standing challenge. In the collaborative digital environments, where multiple professionals use digital platforms such as building information modelling to collaborate on a building design, this challenge has intensified. This research harnesses the functions of blockchain technology, such as consensus mechanisms, distributed broadcasting ledgers, cryptographic algorithms, and non-fungible tokens, to propose a blockchain-based framework to protect building design IPR in the AEC industry. Adopting a design science approach, a framework is proposed and then further developed into a system that is implemented, illustrated, and evaluated in a case study. The system uses non-fungible tokens to tokenize building design IPR and deploys blockchain’s decentralized consensus mechanisms, distributed ledgers, and cryptographic algorithms to safeguard the IPR and its transactions. This prototype system is found feasible with satisfactory performance in enhancing the efficiency of IPR registration and protection, reducing cost, improving information transparency, reinforcing immutability, and preventing non-valuable registrations. Researchers and practitioners are encouraged to develop the framework for different applications such as real-life design IPR protection and design management.
