Title:
BLOCKCHAIN-BASED TRUSTED SHARING METHOD FOR PROTECTION OF PRIVACY-RELATED GOVERNMENT DATA
Document Type and Number:
WIPO Patent Application WO/2022/121058
Kind Code:
A1
Abstract:
The present invention relates to a blockchain-based trusted sharing method for the protection of privacy-related government data. A blockchain is introduced to resolve trust issues between data managers, data sharers, data associated parties, and data users. Strict authorization, application, and use mechanisms ensure that data can only be used by authorized users. More data verification logics are integrated into a blockchain-based smart contract so as to form a mechanism in which data is "available but invisible". In addition, blockchain-based distributed identities allow all the involved people, systems, and data to have corresponding identities and digital certificates, such that the whole process is traceable and non-repudiable.
