Solution Overview

Problem

Existing authentication methods for mobile communication devices, such as those using SIM cards, are vulnerable to cloning and tampering, necessitating a more robust means to verify user authenticity and device integrity.

Innovation Solution

A system utilizing a Non-Fungible Token (NFT) generated from SIM card features, monitored by a distributed trust computing network, to authenticate and verify the authenticity of SIM cards, with deep learning algorithms to detect normal or abnormal changes, and generate new NFTs as needed.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If SIM card authentication is used, then user identification is enabled, but vulnerability to cloning and tampering increases

Engineering Contradiction:

Improveauthentication securityVSAvoidcloning and tampering vulnerability

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The authentication system is segmented into multiple independent components: traditional SIM card authentication, device fingerprinting, and blockchain-based verification. Each component operates independently and contributes to the overall authentication security, making the system more robust against cloning and tampering attacks

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent creates a composite authentication credential that combines multiple types of data: user identity information, device hardware fingerprints, software configuration data, and blockchain-verified authentication records. This composite approach ensures that compromising one element does not compromise the entire authentication system

Inventive Principle:

Principle #40Composite materials

2Reliability

If SIM card features are monitored continuously, then authentication integrity is verified, but system complexity increases

Engineering Contradiction:

Improveauthentication integrityVSAvoidmonitoring system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary authentication by extracting and verifying device fingerprints and SIM card features before resource exchange events occur. Blockchain smart contracts are pre-configured with authentication rules, eliminating the need for complex real-time monitoring during actual transactions

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent introduces blockchain technology as an intermediary layer that simplifies the monitoring complexity. Instead of direct continuous monitoring between devices, the blockchain network acts as a trusted mediator that verifies authentication credentials and enforces security rules, reducing the computational burden on individual devices

Inventive Principle:

Principle #24Intermediary (Mediator)

3Measurement precision

If deep learning algorithms are implemented for change detection, then abnormal changes are detected, but processing time increases

Engineering Contradiction:

Improvechange detection accuracyVSAvoidprocessing time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The system applies deep learning algorithms selectively rather than continuously. Normal operational changes are detected using simpler threshold-based methods, while only suspicious or abnormal changes trigger the more computationally intensive deep learning analysis, reducing overall processing time while maintaining detection accuracy

Inventive Principle:

Principle #16Partial or excessive action

AI summary

A Subscriber Identity Module (SIM) card feature-based Non-Fungible Token. SIM card features, such as communication features, software/hardware features, electrical features, SIM Card behavior features and/or the like are extracted from the SIM card of a user's mobile communication device and a SIM card feature-based NFT is generated and stored on a distributed trust computing network. The distributed trust computing network serves to verify the authenticity of the underlying SIM card features. The NFT is subsequently used as a means for authentication is resource exchange events and other events requiring user/mobile communication device verification.
