Blockchain Data Bank for Secure Medical Record Sharing

The patent segments the centralized data bank into a distributed blockchain network where medical records are divided into blocks distributed across multiple nodes. Each entity (hospital, clinic, patient) has its own node, eliminating the single-point security vulnerability while maintaining data accessibility. The segmentation allows simultaneous data access by multiple entities without compromising security, as each node independently validates and stores copies of the data.

The patent introduces a new dimension of data management by implementing multi-layered access control mechanisms in the blockchain system. Data can be accessed at different levels (patient level, provider level, organizational level) with granular permissions. This dimensional approach allows simplified data retrieval for authorized entities while maintaining robust security through hierarchical control structures that were impossible in traditional centralized systems.

The blockchain system enables entities to autonomously access and share medical records without human intermediaries. Smart contracts automatically manage data sharing agreements, access permissions, and validation processes. When a patient authorizes data sharing, the system automatically grants access to authorized providers, eliminates manual coordination, and maintains audit trails. This self-service mechanism dramatically improves data sharing efficiency while reducing operational complexity.

The patent introduces blockchain technology as a trusted intermediary that replaces human intermediaries. The blockchain network acts as a decentralized mediator that automatically validates transactions, manages consent, and coordinates data sharing between multiple entities. This digital intermediary eliminates the need for human mediators while maintaining the coordination necessary for secure multi-entity data access, thereby improving productivity without increasing complexity.
