Solution Overview

Problem

Existing data verification methods between devices require extensive data exchange, leading to resource occupation and insecure, inaccurate verification results.

Innovation Solution

Implement an integrity verification method using a trusted verification server that compares integrity measurement values and baseline values for data exchanged between devices, reducing the need for full data exchange and ensuring secure and reliable verification.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If full data is exchanged and compared for verification, then verification accuracy is improved, but network resource consumption increases

Engineering Contradiction:

Improveverification accuracyVSAvoidnetwork resource consumption

Core Design Contradiction:

Measurement precisionVSLoss of energy

Solution Approach 1:

The patent extracts only the essential verification information (integrity measurement values and baseline values) from the full data sets. Instead of transferring and comparing complete data, the system extracts and compares only the integrity metrics, significantly reducing network bandwidth consumption while maintaining verification accuracy.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses integrity measurement values as copies or representations of the full data. These integrity values serve as condensed versions that capture the essential verification information without requiring transmission of the actual full data, enabling verification with minimal network resources.

Inventive Principle:

Principle #26Copying

2Reliability

If full data exchange is used for verification, then verification completeness is improved, but verification security deteriorates

Engineering Contradiction:

Improveverification completenessVSAvoidverification security

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a verification server as an intermediary that performs integrity verification independently. This mediator approach ensures that verification is not dependent on direct data exchange between communicating devices, enhancing security by preventing tampering during transmission while maintaining completeness through server-based validation.

Inventive Principle:

Principle #24Intermediary (Mediator)

AI summary

An integrity verification method includes: a first device that sends first data to a second device. The first device sends an integrity measurement baseline value corresponding to the first data to a verification server, and the second device sends an integrity measurement value corresponding to the first data to the verification server. The verification server performs integrity verification on the first data based on the integrity measurement value and the integrity measurement baseline value.
