Blockchain Data Registration with Segmented Metadata

The patent segments the data storage into multiple components: the document hash is stored in the blockchain database for verification, while separate metadata including origin/owner information and timestamp are stored in a structured format within the blockchain transaction. This segmentation allows each piece of information to be stored appropriately while maintaining their关联性 through the transaction structure.

The patent implements a nested structure where the document hash is nested within a transaction that also contains metadata about origin and timestamp. The transaction itself is nested within the blockchain structure, creating layers of information containment. This nested doll approach allows comprehensive information storage while maintaining the verification capability of the hash.

The patent introduces an intermediary system (such as a web service or API gateway) that allows users without blockchain access to register their data. The intermediary handles the complex tasks of generating transactions, signing with appropriate keys, and submitting to the blockchain network, while users simply provide their data through standard web interfaces. This mediator pattern bridges the gap between simple user interaction and complex blockchain operations.

The system implements self-service capabilities where the intermediary automatically performs transaction generation, signing, and submission without requiring user intervention in the complex blockchain protocols. The system autonomously handles key management, transaction construction, and network communication, allowing users to benefit from blockchain verification without needing to understand or interact with blockchain technology directly.

The patent uses cryptographic hashing to create a copy of the document's digital fingerprint (hash) that can be stored and verified without revealing the original document content. The system operator verifies data by comparing hashes rather than examining the actual confidential information. This copying approach allows verification functionality while maintaining confidentiality, as the hash does not reveal the underlying data content.

The patent implements different levels of data visibility: the system operator can see and verify hash values and transaction metadata for validation purposes, but cannot access or view the actual confidential document content. Users retain full access to their own data while the operator has limited access only to verification-necessary information. This local quality differentiation allows verification simplicity for the operator while preserving user data confidentiality.
