The management of data and their storage in the database for an indefinite time, whether in a centralized or decentralized form, is of great importance for the operation of the system and its efficiency. One of the challenges that decentralized systems are facing is the lack of decentralized management of databases, because they have limitations in terms of inserting, updating, and deleting data. The generation of diplomas is a more sensitive issue and one of the reasons why it has not been digitalized to date is the fact that centralized systems do not offer sufficient security for the generation of such documents, since the same systems must be controlled by third people or administrators of the system, where there is also the suspicion of data misuse. Through the paper, we will compare centralized and decentralized databases, the operation of decentralized databases, and finally present a scheme of our vision about the operation of the database in the blockchain-based system for the generation and verification of diplomas.

“…Most conventional access controls for IoT are based on a centralized architecture with many limitations, such as singlepoint-of-failure, trusted third-party requirements, and low scalability [5][6] [7]. Meanwhile, the maturity of Blockchain drives towards applying to numerous areas beyond cryptocurrencies to solve concerns of trust and security, such as digital certificate [8], smart factory [9], smart parking [10], healthcare [11], and traceability [12]. Additionally, there have been various research studies on the amalgamation of Blockchain to solve problems in existing IoT systems regarding scalability, interaction, security, privacy, and trust [13][14] [15][16] [17].…”

Blockchain-based access control mechanisms have garnered significant attention in recent years due to their potential to address the security and privacy challenges in the Internet of Things (IoT) ecosystem. IoT devices generate massive amounts of data that are often transmitted to cloud-based servers for processing and storage. However, these devices are vulnerable to attacks and unauthorized access, which can lead to data breaches and privacy violations. Blockchain-based access control mechanisms can provide a secure and decentralized solution to these issues. This paper presents an improved Attribute-based Access Control (ABAC) approach with enhanced flexibility, which utilizes decentralized identity management on the Substrate Framework, codifies access control policies by Rust programming language, and executes access control policies on-chain. The proposed design ensures trust and security while enhancing flexibility compared to existing works. In addition, we implement a PoC to demonstrate the feasibility and investigate its effectiveness.
