Cloud-based Manufacturing Blockchain: Secure Knowledge Sharing for Injection Mould Redesign
Zhi Li, Layne Liu, Ali Vatankhah Barenji, Waiming Wang · Procedia CIRP · 2018
This paper proposes a cloud-based manufacturing knowledge sharing system for injection mould redesign (IMR) based on blockchain technology. In our proposed system, private cloud is used to store the IMR knowledge, and blockchain provides standards and protocols for implementing the system as well as ensuring the security in a trustless environment. K-Nearest Neighbors is used for retrieving the blockchain-based document knowledge. The proposed system not only can facilitate injection mould redesign, but also provide a mechanism for knowledge owners to share their own assets securely.
