Solution Overview

Problem

The existing methods for managing data from sensors in IoT environments are inefficient and costly due to the time and resources required for encrypting and decrypting large amounts of data, while also posing risks to privacy due to the handling of personal information.

Innovation Solution

A method and apparatus for managing data that encrypts only specific parts of the information collected by sensors or intermediate network devices, allowing for secure transmission and analysis without decrypting the data, using a data management system that includes a data receiving unit, storage unit, and analysis performing unit capable of analyzing encrypted data without decryption.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If data is encrypted to improve security, then data security is improved, but time and cost for encryption and decryption increase

Engineering Contradiction:
Improvedata securityVSAvoidtime for encryption and decryption
Core Design Contradiction:
ReliabilityVSLoss of time

Solution Approach 1:

The patent segments data into encrypted and non-encrypted portions, allowing only necessary parts to be decrypted for analysis while maintaining security for sensitive information. This reduces the amount of data requiring decryption operations.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different portions of data are treated differently - some parts are encrypted while others remain non-encrypted. This local differentiation allows analysis of non-sensitive data without decryption while maintaining security encryption where needed.

Inventive Principle:
Principle #3Local quality

2Reliability

If all data is encrypted for security, then data security is improved, but processing and analysis time increases

Engineering Contradiction:
Improvedata securityVSAvoiddata processing speed
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent divides data into segments that require encryption and segments that do not, enabling faster processing of non-encrypted portions while maintaining security for encrypted portions.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent applies encryption selectively to specific data portions rather than uniformly encrypting all data, improving overall processing efficiency while maintaining necessary security levels.

Inventive Principle:
Principle #3Local quality

3Measurement precision

If data is decrypted for analysis, then analysis accuracy is improved, but data security risk increases

Engineering Contradiction:
Improveanalysis accuracyVSAvoiddata leakage risk
Core Design Contradiction:
Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent segments data into encrypted and non-encrypted parts, allowing analysis of non-sensitive portions without decryption while maintaining security for sensitive information that could cause harm if leaked.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different security treatments are applied to different data portions based on their sensitivity, allowing accurate analysis of non-sensitive data while protecting sensitive data from potential leakage risks.

Inventive Principle:
Principle #3Local quality

4Reliability

If encryption is applied to protect personal information, then privacy protection is improved, but processing cost increases

Engineering Contradiction:
Improveprivacy protectionVSAvoidprocessing cost
Core Design Contradiction:
ReliabilityVSLoss of energy

Solution Approach 1:

The patent segments personal information into encrypted and non-encrypted portions, reducing the computational cost of encryption operations while maintaining privacy protection for sensitive information.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Encryption is applied locally only to sensitive personal information portions rather than uniformly to all data, reducing overall processing costs while maintaining necessary privacy protection.

Inventive Principle:
Principle #3Local quality
