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.

Example of cooperative modeling. Designer 1 adds a model (colored by green) on the scene and submits its commit to the network. Designer 2 can then perform checkout to download the model added by designer 1. So, both designers can share and render the model. (Color figure online)

Example of data authentication. Since the decentralized network securely holds the 3D data and important information (e.g., author, date, etc.), a designer can search 3D models that are similar to the query model. The designer can also find which part of a similar 3D model infringes the intellectual right by comparing those models.

Our prototype is built on Blender modeling tool, Ethereum blockchain, and Swarm decentralized storage. Applications introduced in this paper are realized via the client code and the smart contract code.

Time of storing the data on the Swarm [10] storage and storing its storage address on the Ethereum [6] blockchain. The graph shows that the blockchain overhead is significantly larger than the storage overhead. The average time is reported out of 10 different tests.
