Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing identification and authorization systems are vulnerable to tampering, allowing individuals to illegitimately obtain privileges by deceiving the system into determining incorrect identities.

Innovation Solution

Implementing a data acquisition module with a unique and inaccessible encryption key stored in a controller, which encrypts and decrypts information, ensuring that only the correct key can access and modify sensitive data, thereby preventing unauthorized access and tampering.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If identification information is stored in accessible memory, then ease of operation is improved, but security against tampering deteriorates

Engineering Contradiction:

Improveaccess to identification informationVSAvoidtampering with identification system

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent extracts the encryption key from accessible memory and stores it in inaccessible memory within the controller. This separation allows identification information to remain accessible for operation while the decryption key is protected from tampering, resolving the contradiction between ease of access and security.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent introduces encryption as an intermediary mechanism between the stored identification information and the controller. The encrypted form can be stored and transmitted, but only the controller with the unique key can decrypt and access it, preventing tampering while maintaining operational access.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If encryption is implemented with unique keys, then security is improved, but device complexity increases

Engineering Contradiction:

Improvesecurity of identification systemVSAvoidencryption module and key management

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent merges the encryption module and unique key storage directly into the controller unit. This integration consolidates multiple security functions into a single device, reducing overall system complexity while maintaining strong security through unique per-controller keying.

Inventive Principle:

Principle #5Merging (Combining)
