基于量子加密的医联体数据安全访问控制系统
By using a quantum-encrypted data security access control system for medical consortia, electronic medical record data is fragmented into fine-grained segments and stored with semantic awareness. This solves the problem of data sharing and access control in cross-institutional medical consortia, enables efficient data reorganization and privacy computing, and ensures data security and integrity.

AI Technical Summary
In a cross-institutional medical consortium environment, existing technologies struggle to achieve secure sharing and access control of fine-grained electronic medical record data, and cannot maintain semantic dependencies and temporal logical relationships between data fragments, resulting in low data reconstruction efficiency and a high risk of privacy leaks.
The medical consortium adopts a quantum-encrypted data security access control system. The system performs fine-grained data sharding of electronic medical record data through a data sharding module, embeds semantic dependency tags and time logic tags through an annotation encryption module, performs semantically aware storage deployment through a distributed storage module, and implements decentralized permission verification through an access verification module. It also supports data reconstruction and privacy computing in encrypted state.
It enables secure sharing and access control of cross-institutional data, maintains the integrity of the data's inherent diagnostic and treatment logic, supports efficient reassembly and privacy-preserving computation in encrypted form, and improves data utilization efficiency and security.
