Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional electronic certificate issuing systems for financial institutions cannot reliably verify the authenticity of issued certificates, as they lack a mechanism to distinguish between genuine and forged certificates, especially when watermarks are embedded after the certificate is forged.

Innovation Solution

A method and system utilizing a blockchain to verify the authenticity of financial institution certificates by comparing the index hash values of the initial and re-issued certificates, ensuring that any changes or forgeries can be detected through a blockchain-based verification process.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional watermarking technology is used to verify certificate authenticity, then the system can issue certificates with embedded watermarks, but forged certificates with embedded watermarks cannot be distinguished from genuine ones

Engineering Contradiction:

Improvecertificate authenticity verificationVSAvoidforgery detection accuracy

Core Design Contradiction:

ReliabilityVSMeasurement precision

Solution Approach 1:

The patent applies preliminary action by recording the original certificate data and its hash value on the blockchain before any potential forgery occurs. This creates a permanent, immutable reference point that enables later verification. When a certificate is issued, its cryptographic hash is stored on the blockchain, allowing future comparisons to detect any alterations or forgeries with high precision.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces blockchain technology as an intermediary between the certificate issuance system and the verification process. The blockchain acts as a neutral, decentralized ledger that stores reference data independently, allowing verifiers to compare certificates against this trusted external source rather than relying solely on embedded watermarks that can be replicated by forgers.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If electronic certificates are issued remotely without physical access to financial institutions, then client convenience is improved, but the ability to provide official seals for authentication is lost

Engineering Contradiction:

Improvecertificate access convenienceVSAvoidcertificate authentication

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent replaces the mechanical system of physical seals and stamps with a cryptographic verification system based on blockchain technology. Instead of relying on physical embossed seals that can be replicated, the system uses cryptographic hash functions and blockchain's immutable ledger to provide digital authentication that is both remote-accessible and highly reliable.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The blockchain-based verification system serves multiple functions: it provides remote certificate issuance, enables authentication without physical seals, creates immutable audit trails, and allows for efficient verification comparisons. This multi-functional approach replaces several traditional separate systems (physical seal application, manual verification, document storage) with a unified digital solution.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

Transaction ID information corresponding to proof certificate-verifying transaction information is transmitted to a block chain retention server if a request for proof certificate information is sensed, when the proof certificate-verifying transaction information generated by using the proof certificate information, to be provided to a customer, is recorded in a block chain retention server and the transaction ID information is managed. The proof certificate-verifying transaction information corresponding to the transaction ID information is acquired from the block chain retention server. A proof certificate index hash value used for comparison, acquired from the proof certificate information to be provided to a customer and corresponding to a request, is compared with a proof certificate-verifying index hash value acquired from the proof certificate verifying-transaction information. Verification information generated with reference to the comparison result of the proof certificate index hash value used for comparison and the proof certificate-verifying index hash value are provided.
