A contracted container-based code component collaboration model with reusable but invisible right management

Abstract

Existing methodologies for the code collaboration are facing challenges such as leakage of privacy data and insecure centralized management. To alleviate these challenges, we propose a contracted container-based code component collaboration model. Firstly, a specific blockchain is developed as a computational network that supports the storage and verification of sensitive data, which integrates an off-chain file system and encryption algorithms to realize the traceability and version control of privacy data. Secondly, the containerization and smart contract technology are introduced to enhance access control and the secure management and collaboration of code components. Thirdly, a protocol is designed to ensure the high reliability of cross-node information communication. Finally, the results of the prototype experiment demonstrate that the model effectively resists common attacks, meets critical security criteria, and maintains stable performance in the collaboration process. Moreover, compared to the state-of-the-art research, our model implements more valuable functionality characteristics, design goals and security attributes in the code component collaboration practice.
