Cross-domain design of blockchain smart contract for library and healthcare privacy

The blockchain technology designed by information security experts empowers in library service and healthcare service via smart contracts. Advanced blockchain technology provides a mechanism for smart contracts. Through intelligent threshold design and the open and tamper-proof nature of the blockchain, smart contracts have become a new generation of information security technology. In the next-generation library services, traditional borrowing materials from the library have evolved into a limited-time sharing service for electronic materials. These electronic materials have various loan periods and sharing time-varying by different borrower privileges. This study designs a patron-centric account's smart contract to disseminate library information more effectively and collect accurate library data. The smart contract automatically triggers the loan period and extends this mechanism to designing a personal health privacy sharing protocol for improving the one-time authorization sharing mechanism. As a result, this study may provide blockchain smart contract designs shared by library information and healthcare through cross-domain consideration and scheme.
