Solution Overview
Problem
Conventional IoT infrastructure lacks effective security measures for continuous access control and differentiates users inadequately, making it vulnerable to hacking and data theft, relying primarily on pins and passwords without continuous monitoring or advanced authentication mechanisms.
Innovation Solution
A distributed blockchain-based IoT network system that dynamically allocates and validates IoT tokens based on transaction blocks, providing continuous security by linking user access to legitimate transaction trails and zones, using cryptographic consensus protocols for secure access control and token management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional IoT infrastructure uses centralized systems with pins and passwords for access control, then ease of operation is improved, but reliability and security are worsened due to vulnerability to hacking and lack of continuous monitoring
Solution Approach 1:
The patent segments the centralized authentication system into distributed blockchain-based smart contracts. Each IoT device and user receives segmented access tokens that are validated across multiple distributed nodes rather than relying on a single centralized server, thereby improving security while maintaining ease of operation through automated token validation.
Solution Approach 2:
The patent introduces blockchain technology and smart contracts as intermediaries between users and IoT devices. These intermediaries provide continuous automated validation of access rights through token verification, replacing manual password checking and providing continuous security monitoring without complicating user interaction.
2Device complexity
If conventional IoT infrastructure relies on trusted communication between nodes and centralized server, then device complexity is reduced, but object-affected harmful factors increase due to hacking and data theft vulnerabilities
Solution Approach 1:
The patent converts the inherent vulnerability of trusted communication into a benefit by implementing cryptographic verification through blockchain. Instead of trusting communication channels, the system uses cryptographic tokens and smart contracts to verify legitimacy, transforming potential security weaknesses into strengthened security through distributed consensus and immutable transaction records.
3Ease of operation
If conventional IoT infrastructure uses password validation for access, then ease of operation is improved, but loss of information increases due to inability to provide continuous security monitoring
Solution Approach 1:
The patent implements continuous security monitoring through blockchain-based smart contracts that continuously validate IoT tokens for each transaction. Unlike one-time password validation, the system maintains continuous oversight by requiring token verification for every access request, ensuring ongoing security without adding operational complexity for users.
