Solution Overview

Problem

Existing digital systems lack efficient and secure methods for managing and accessing digital resources across decentralized networks, particularly in verifying user authorization and device compatibility for resource access.

Innovation Solution

A system utilizing distributed block chain ledgers for transaction and rights management, enabling secure and cross-platform access to digital resources by verifying user authorization and device compatibility through separate transaction and rights ledgers, with tamper-resistant features.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If a single distributed block chain ledger is used for both transactions and access rights management, then the system structure is simplified, but the functionality and security are insufficient

Engineering Contradiction:
Improvesystem structureVSAvoidsecurity and functionality
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The patent divides the block chain system into separate ledgers: a transaction ledger for recording resource transactions and a rights ledger for managing access rights. This segmentation allows each ledger to specialize in its function, improving security and reliability while maintaining manageable complexity through modular architecture.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a rights ledger as an intermediary between the transaction ledger and the digital resource. This intermediary layer verifies user authorization and device compatibility before granting access, enhancing security without requiring changes to the core transaction processing mechanism.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If traditional centralized verification methods are used, then the verification process is simple and fast, but the system lacks decentralization and security

Engineering Contradiction:
Improveverification processVSAvoiddecentralization and security
Core Design Contradiction:
Ease of operationVSReliability

Solution Approach 1:

The system enables nodes to autonomously verify transactions and access rights using cryptographic proofs stored on the block chain. Each node can independently validate user authorization and device compatibility without relying on a central authority, achieving both decentralization and operational simplicity.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The patent replaces traditional centralized mechanical verification systems with cryptographic verification based on public-key infrastructure and smart contracts. This substitution maintains the simplicity of verification while enabling decentralization and enhanced security through mathematical proofs rather than trust-based mechanisms.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Device complexity

If access rights are tightly coupled with transactions in a single ledger, then the system is simpler to manage, but flexibility and cross-platform access are limited

Engineering Contradiction:
Improveledger managementVSAvoidcross-platform access
Core Design Contradiction:
Device complexityVSAdaptability or versatility

Solution Approach 1:

The rights ledger is designed to store universal access rights that can be verified across different platforms and devices. By separating access rights from transaction-specific data, the system enables flexible, cross-platform access while maintaining simple ledger management through standardized right representations.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The patent adds a new dimension to the system architecture by introducing a separate rights ledger that operates independently from the transaction ledger. This dimensional separation allows access rights to be managed in one dimension while transactions occur in another, enabling cross-platform flexibility without complicating individual ledger management.

Inventive Principle:
Principle #17Another dimension (Dimensionality change)
