“…Similarly, they can also call the functions in smart contracts deployed in blockchain. With the help of smart contracts, data sharing intermediaries can provide services to stakeholders in the form of DAPPs [ 39 , 40 ]. Related operations such as attribute distribution and user management will become open and transparent [ 41 ].…”

With the development of digital healthcare, sharing electronic medical record data has become an indispensable part of improving medical conditions. Aiming at the centralized power caused by the single attribute authority in current CP-ABE schemes and the problem that cloud servers are curious and even malicious, we design a revocable CP-ABE EHR sharing scheme with multiple authorities (MA-RABE) in blockchain. In this solution, a group of authorities complete user attribute distribution, key generation and user management through secret sharing and transactions. Besides, we innovatively implemented a distributed one-way anonymous key agreement so that other participants cannot obtain useful information from the fully hidden policy embedded in the ciphertext. Taking into account the computational overhead of a large number of bilinear operations in the decryption process, the solution also supports the cloud server to pre-decrypt the ciphertext, and the data user only needs to perform exponentiation operation once to obtain the plaintext from the pre-decryption result. Theoretical analysis and performance evaluation show that the scheme has reliable security and lower user revocation and ciphertext update overhead.

“…After compilation is finished in the EVM compiler, they can be uploaded to a blockchain network via an Ethereum client. e execution of smart contracts requires no participation of intermediaries or manpower, thus saving time and cost; smart contracts have higher computing efficiency and accuracy; and they cannot be reversed once automatically executed, thus offering higher transaction security [21,22]. ⑤ Application layer: the application layer of blockchain can achieve good scalability through the distributed application (DApp) and application program interface (API).…”

The development of new technologies drives the digital transformation of the credit reporting industry and also brings new opportunities for cross-border credit reporting cooperation. This study focuses on a cross-border credit information sharing platform based on blockchain 3.0 and its legal guarantee, with an aim to promote the integrated development of credit reporting across the Taiwan Straits. This study first points out the difficulties of cross-border credit information sharing; second, the technical characteristics of blockchain such as distributed storage, point-to-point transmission, security and credibility, open source, and programmability are naturally suitable for solving the information sharing problems in the credit reporting industry. So, this study proposes a framework and a specific design of a cross-strait credit information sharing platform based on blockchain 3.0 infrastructure; finally, in order to ensure the smooth operation of the platform, this study suggests signing a series of nonnormative “soft law” documents in the principles of equality, willingness, and consultation to provide legal guarantee for cross-border credit sharing.

With the development of digital technology, the curriculum design of art majors is also quite different from traditional courses. With the continuous development of information technology and the continuous maturity of campus network technology, teaching resources have become an important part of information resources. High-quality teaching resources play an important role in improving teaching quality and excavating educational development potential. However, traditional classroom teaching is difficult to meet people’s needs. In the context of the current new normal, the way of social and economic management has changed. On the one hand, traditional course teaching resources store information in the forms of paper lesson plans, PPT courseware, discrete pictures, and video files. These forms of storage are not conducive to the distribution and sharing of resources. On the other hand, these teaching resources are scattered among the teaching teachers. As the curriculum develops, the courses taught by teachers change. Because schools lack effective means for unified management, these teaching resources are easily lost. The used method is not conducive to the accumulation of teaching resources or the continuation and development of courses. In order to present good results, these materials usually occupy a large amount of storage space. Therefore, some existing information-based teaching platforms cannot meet the demand. We use network and web technology to develop a teaching file management system, which is very necessary. This paper firstly compares the mature teaching resource management system on the market and some problems in its professional application. Secondly, the article analyzes the actual situation of teaching resource management of art design majors in China and generally describes the system development background and technology. Then, the paper analyzes the requirements of the system in detail by using the object-oriented method and gives the overall design and implementation method of the system. These methods include the use case diagram of the subsystem, the flow chart of the main module, the system architecture, and the design and application of UML. Finally, this paper designs a test case for the teaching resource management system.
