Data Sharing Control with Blockchain-Based Self-Sovereign Identity Management System

Cloud computing is often praised for its excellence in facilitating data sharing and manipulation, which enables various parties to collaborate and exchange information within the same technical domain

. Although the benefit of sharing data is massively effective due to an unlimited number of actors accessing the data simultaneously without it losing value or being altered, factors such as data protection, security, and transparency in data management are also becoming equally important for data owners

. Therefore, efficient data handling, while taking into account both legal and ethical obligations, is an indispensable prerequisite for reaping the benefits of collaborative data sharing. In that, blockchain network (BCN) appears to be one of the most prominent technologies that enable distributed settings for data sharing and help overcome such legal and technical difficulties. Blockchain technology can also significantly improve the management of IP by providing an immutable proof of ownership and automating transactions. Some possible examples include artists registering digital art as nonfungible tokens (NFTs) to ensure secure sales and royalties, inventors filing blockchain-based patents to prioritize and attract investors, or musicians using smart contracts to automate royalty payments and track distribution.
