“…Blockchain [21][22][23] and references [24 and 25] has the advantages of data traceability, high data security, and data tamper resistance, which can solve the problem of secure data storage and multiparty noncompliance. Moreover, the issue of data sharing in the context of mutual trust is very applicable to data asset management [26][27][28][29][30].…”

“…In addition, when ocean data assets are shared across departments, data sharing methods using traditional centralized systems face security risks such as data being easily tampered with and illegal copying and utilization. Ding et al [26] developed a blockchain-based ocean data sharing platform based on the alliance chain, which realized data sharing between ocean departments and better protected the rights and interests of owners in the cross-departmental use of ocean data. It prevents data from being tampered with and copied in violation of regulations, and at the same time reduces the cost of data transactions caused by the existence of third parties, improves the motivation of various departments to share and open data on the data asset value network, and further forms a healthy development ecological environment [36,37].…”

The adoption of blockchain technology can provide data asset management’s high security, privacy, and traceability. After a comprehensive investigation of the present blockchain-based data asset management mechanism, it was determined that it is only relevant to a portion of the blockchain system design. To address this issue, a new model of data asset management based on blockchain technology is being developed, which incorporates applications at all levels of the blockchain system. This model implements a network layer node authority control mechanism, a consensus layer consensus mechanism with customizable attributes, improved data query efficiency at the data layer by optimizing the structure and building indexes, intelligent data management, and smart contract layer management. Furthermore, at the transaction layer, sharing information encryption using customizable encryption algorithms is introduced. The experimental results reveal that, when compared to the traditional paradigm, the new blockchain-based data asset management strategy enhances the efficiency of on-chain data queries by 2.33 times.

“…Some of these limitations include limited granularity, complexity in access policy management and protection, difficulties involved in access revocation, and lower operational efficiency. Attribute based access control(ABAC) is preferred over the other access control methods due to its capability to provide finer granularity in access control using multiple attributes and to resolve most the limitations mentioned above [1].…”

The secure access and reliable access revocation methods of modern digital systems are based on access control mechanisms. Access policies, which are used in access control mechanisms, are very important in safeguarding security and ensuring data protection. It is evident that the protection and tamper-proofing of such policies are very important. In addition, efficient access revocation schemes are required to promptly remove access privileges when users are no longer needed or authorized. The shortcomings of existing systems in ensuring efficient, streamlined access revocation and tamper-proof protection of access control policies underscore the need for innovative solutions. In this paper, we have introduced the novel Blockchain Attribute-Based Secure Data Management Model (BAB-SDMM). Our model is the first to integrate attribute-based encryption (ABE), Attribute-Based Access Control (ABAC), and blockchain to achieve multiple security features as well as provide partial and complete revocation at the same time. The experimental results and analysis, performed using the Ethereum blockchain network, demonstrated the enhanced performance of the proposed BAB-SDMM compared to existing research works.
