Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Electronic documents are easily altered for fraudulent activities in online environments, compromising security and authenticity in banking and other online activities.

Innovation Solution

A security scheme utilizing a verification server that generates hash values based on electronic data representing the document, distributes these values via a blockchain, and compares them to verify the authenticity of the document, generating a fraud alert if alterations are detected.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If electronic documents are distributed via computer networks, then ease of operation and accessibility are improved, but reliability and security are worsened due to easy alteration for fraudulent activities

Engineering Contradiction:

Improveease of document distributionVSAvoiddocument authenticity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary actions by generating hash values of the original electronic document and storing them in a blockchain before distribution. This creates a pre-established reference point that enables later verification of document authenticity, resolving the contradiction by preparing security measures in advance while maintaining distribution ease

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces hash values and blockchain technology as intermediary elements between the original document and the distributed copies. These intermediaries serve as trusted mediators that verify authenticity without restricting distribution, allowing the document to be widely shared while maintaining reliability through the intermediary verification mechanism

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If verification mechanisms are implemented to detect alterations, then reliability and security are improved, but device complexity and processing requirements are worsened

Engineering Contradiction:

Improvefraud detection capabilityVSAvoidverification system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The verification mechanism extracts only the essential hash values from the complete document for storage and comparison. By taking out just the critical verification element (hash) rather than the entire document, the system achieves reliable fraud detection while minimizing complexity and processing requirements

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The system transforms the document into a different parameter form (hash value) for verification purposes. This parameter change converts the complex original document into a simplified numerical representation that maintains verification reliability while dramatically reducing complexity and processing demands

Inventive Principle:

Principle #35Parameter changes

AI summary

Authentication of electronic document is based on multiple digital signatures incorporated into a blockchain. Structured data, metadata, and instructions may be hashed to generate the multiple digital signatures for distribution via the blockchain. Any peer receiving the blockchain may then verify an authenticity of an electronic document based on any one or more of the multiple digital signatures incorporated into the blockchain.
