Solution Overview

Problem

Conventional product identification and authorization systems are vulnerable to impersonation, as similar serial numbers for products of the same category can be guessed, allowing unauthorized access to authorization keys, compromising the authenticity of product usage.

Innovation Solution

A system and method that utilizes a secured product identification code, comprising a serial number and a cryptographic code generated based on a cryptographic algorithm, where a trusted service provider extracts and transmits this code to the product manufacturer for authentication, ensuring only the legitimate product manufacturer can issue an authorization key.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of manufacture

If conventional serial numbers are used for product identification, then ease of manufacture and operation are improved, but security and reliability deteriorate due to guessability by imposters

Engineering Contradiction:
Improveease of product identificationVSAvoidauthenticity of product identification
Core Design Contradiction:
Ease of manufactureVSReliability

Solution Approach 1:

The product identification code is segmented into multiple components: a serial number and one or more cryptographic codes. This segmentation allows the system to maintain the simplicity of serial numbers while adding security through cryptographic elements, resolving the contradiction between ease of manufacture and reliability

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent creates a composite identification structure combining conventional serial numbers with cryptographic codes. This composite approach integrates the simplicity of traditional identification with the security of cryptographic verification, enabling both ease of manufacture and high reliability

Inventive Principle:
Principle #40Composite materials

2Reliability

If cryptographic codes are added to product identification, then reliability and security are improved, but device complexity increases

Engineering Contradiction:
Improveauthenticity of product identificationVSAvoidcomplexity of identification system
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

A trusted service provider acts as an intermediary between the product and manufacturer, handling the extraction and transmission of cryptographic codes. This intermediary simplifies the overall system architecture by centralizing complex cryptographic operations, reducing device complexity while maintaining high reliability

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The cryptographic verification process is designed to be self-service, where the product itself contains the necessary cryptographic codes for verification. This eliminates the need for complex external verification infrastructure, reducing device complexity while ensuring authenticity

Inventive Principle:
Principle #25Self-service
