A flexible and efficient UNITID-based access control (UBAC) model for environmental monitoring data

With the increasing deployment of equipment in field monitoring environments, managing the resulting data presents increasing challenges in terms of storage, organisation, visualisation, and role-based access control. Regulating management is crucial to ensure users can only view or interact with data relevant to their roles. This paper proposes a novel unit identification (UNITID)-based access control (UBAC) model to establish unique and precise relationships between users and data. This UBAC model enables centralised management of all data through a unified map service while supporting the dynamic extraction, organisation, and construction of virtual map services from a single data map. The UBAC model has been successfully implemented in software, and experimental results demonstrate its superiority over existing methods in terms of query simplicity and efficiency. In addition, the model proves highly effective in practical applications, with potential improvement in the efficiency and scalability of environmental monitoring data workflows.
