Blockchain Audit Trail for Electronic Certification Reliability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electronic certification systems rely on the reliability of the certificate authority, and if the private key leaks, the entire trust model collapses, with complex verification processes that increase processing costs, especially when multiple nodes are involved.
Innovation Solution
An electronic certification system using an audit trail registered in a blockchain to ensure data reliability, where the audit trail is registered by the first terminal and provided to the second terminal, allowing for secure and efficient verification without the need for complex signature verification processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional electronic certificate verification processes are used, then data reliability can be guaranteed through certificate authority signatures, but the verification process becomes complex and processing costs increase
Solution Approach 1:
The patent extracts the core verification function from the complex certificate authority signature verification process and implements it through blockchain's inherent immutable ledger mechanism. Instead of verifying electronic signatures through multiple certificate layers, the system stores verification data directly in the blockchain, allowing simple existence checks that guarantee reliability without complex processing.
Solution Approach 2:
The blockchain serves as an intermediary between data terminals and verification processes. Rather than directly verifying certificate signatures between terminals, the blockchain mediates by storing and providing verification data, simplifying the interaction while maintaining security and reliability guarantees.
2Reliability
If multiple nodes are involved in the certification process, then system robustness improves, but processing costs and verification complexity increase significantly
Solution Approach 1:
The patent segments the certification system into independent data terminals that directly interact with the blockchain, eliminating the need for multiple intermediary certificate authority nodes. Each terminal can independently verify data by checking the blockchain ledger, maintaining system robustness through distributed verification while improving processing efficiency by removing redundant nodes.
3Reliability
If traditional certificate authority systems are used, then electronic signature verification provides security, but the trust model collapses if the private key leaks
Solution Approach 1:
The patent creates a distributed copy of verification data across the blockchain network rather than relying on a single certificate authority's private key. Multiple nodes maintain identical copies of the verification ledger, so the system remains secure even if individual nodes fail or are compromised, eliminating the single point of failure inherent in traditional CA systems.

AI summary
An electronic certification system that can simplify a process for verification of reliability while improving reliability. The electronic certification system guarantees reliability of data using an audit trail registered in a blockchain, the data being provided to a second terminal such as a client by a first terminal such as a server, the first terminal includes audit trail registration for registering information and the data as the audit trail in the blockchain, the information relating at least one of the first terminal, an administrator of the first terminal, and a program configured to run on the first terminal and exchange the data with the second terminal, and an audit trail provider for transmitting the audit trail to the second terminal. The second terminal determines that the data is reliable if the audit trail provided by the audit trail provider has been registered in the blockchain.
