Blockchain Server Authentication via Asset Hash Verification

The patent introduces blockchain technology as an intermediary layer between the supply chain database and the authentication system. The blockchain stores cryptographic hashes of asset information and certificates, acting as a tamper-proof mediator that verifies data integrity without exposing the underlying database structure. This resolves the contradiction by enabling traceability through blockchain's immutable ledger while maintaining data security through cryptographic verification.

The patent creates cryptographic copies (hashes) of the original asset information and stores them in the blockchain. Instead of storing sensitive raw data directly in the blockchain, it stores verified cryptographic representations that can be used for authentication and traceability without compromising the security of the original data. This allows traceability functionality while preserving data security.

The patent implements automated authentication where the system itself performs certificate verification and asset information validation without manual intervention. The authentication module automatically queries the blockchain, verifies certificates, and compares asset information, eliminating human errors while maintaining streamlined operations through automation rather than increased system complexity.

The patent establishes an automated feedback loop where the authentication system continuously verifies asset information against the blockchain ledger and provides real-time authentication results. This automated feedback mechanism replaces manual certificate transmission with a self-correcting system that automatically detects and reports authentication status, improving reliability without requiring complex manual procedures.

The patent performs preliminary actions by pre-storing asset information and certificates in the blockchain during manufacturing and supply chain processes. When authentication is needed, the system simply retrieves and verifies pre-stored data rather than conducting comprehensive inspections from scratch. This preliminary recording enables fast authentication while maintaining comprehensive verification accuracy.

The patent extracts only the essential verification elements (cryptographic hashes and certificates) from the complete asset information and stores them in the blockchain. During authentication, the system extracts and compares only these critical elements rather than examining all asset details, achieving comprehensive authentication accuracy with minimal processing time by focusing on the most important verification points.
