Abstract
The intellectual value of digitized 3D properties in scientific, artistic, historical, and entertaining domains is increasing. However, there has been less attention on designing an immutable, secure database for their management. We propose a secure 3D property management platform powered by blockchain and decentralized storage. The platform connects various 3D modeling tools to a decentralized network-based database constructed on blockchain and decentralized storage technologies and provides the commit and checkout of the 3D model to that network. This structure provides 3D data protection from damages and attacks, intellectual property (IP) management, and data source authentication. We analyze its performance and show its applications to cooperative 3D modeling and IP management.
