Integrating blockchain-based access control model TBAAC for privacy and accountability for water science project

This research came from the need for a client application where researchers want to store and share their large-sized research data among their community. This application necessitates data exchange while respecting the media content owner's privacy and sharing rights. To develop this client decentralized application, each issue related to storage, propagation capacity, or access permissions needs to be addressed along with the network structure and execution flow to work as swiftly as possible. To mitigate these challenges, we introduce the TBAAC (Token-based attributed access control) management, a modified attribute-based access control (ABAC) scheme to explore the full potential of the used schemas and strategies in a blockchain-supported client application. The presented token-based attributed access control has been validated through regress simulations and specified use cases of the DWS client application.
