Solution Overview

Problem

The Metaverse faces challenges in decentralized identity management, security, and privacy, particularly in integrating blockchain technology to ensure trust, security, and data integrity while addressing scalability, interoperability, and privacy concerns.

Innovation Solution

A decentralized identity management system is introduced, utilizing a blockchain layer with a business layer above it, facilitated by smart contracts and a hierarchical trust model. This system includes Entity, Certificate, and Issuer data structures and employs Elliptic Curve Cryptography for secure user verification and authentication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If blockchain technology is integrated into the Metaverse for decentralized identity management, then security and trust are improved, but device complexity and implementation difficulty increase

Engineering Contradiction:

ImprovesecurityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system segments identity management into distinct blockchain components: identity verification smart contracts, credential issuance modules, and authentication protocols. This modular approach allows each security function to be independently implemented and verified, reducing overall system complexity while maintaining robust security through distributed verification across multiple blockchain nodes

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

Blockchain smart contracts serve as intermediaries between users and Metaverse applications, automatically handling identity verification and credential validation. This intermediary layer simplifies the authentication process for end users while providing comprehensive security checks, as the smart contracts enforce predefined security rules without requiring complex client-side implementation

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If decentralized identity management is implemented, then privacy protection is improved, but ease of operation deteriorates due to complex authentication processes

Engineering Contradiction:

Improveprivacy protectionVSAvoidease of operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Users are empowered to self-manage their digital identities through cryptographic key pairs stored in secure wallets. Users can independently issue, revoke, and manage their own credentials without requiring centralized authority approval, thereby enhancing privacy control while simplifying the operational process through intuitive wallet interfaces that abstract away the cryptographic complexity

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The blockchain-based identity system provides universal authentication across multiple Metaverse applications and platforms. A single decentralized identity can be used to access various virtual environments, eliminating the need for separate registration processes at each platform and significantly improving ease of operation while maintaining consistent privacy protection standards across the entire Metaverse ecosystem

Inventive Principle:

Principle #6Universality (Multi-functionality)
