Blockchain Infringement Detection via Double-Layer Smart Contract Logic

Solution Overview

Problem

Current blockchain-based systems lack an efficient method for detecting infringement risks in deposited works, as they rely on either rapid but potentially inaccurate detection or in-depth but time-consuming analysis, failing to balance efficiency and accuracy.

Innovation Solution

A blockchain-based infringement detection method utilizing a double-layer detection mechanism, where a first detection logic uses a small amount of feature data for rapid matching and a second detection logic employs key data for in-depth matching, ensuring both efficiency and accuracy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If rapid detection using feature value matching is performed, then detection speed is improved, but detection accuracy may deteriorate

Engineering Contradiction:

Improvedetection speedVSAvoiddetection accuracy

Core Design Contradiction:

SpeedVSMeasurement precision

Solution Approach 1:

The detection process is segmented into two distinct layers: a first detection logic layer that performs rapid feature value matching for initial screening, and a second detection logic layer that performs comprehensive key data matching for accurate verification. This segmentation allows the system to achieve both speed and accuracy by applying appropriate detection methods at different stages.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first detection logic performs preliminary action by quickly matching feature values to identify potential infringements before the second detection logic conducts thorough key data verification. This preliminary screening filters out obvious non-infringements early, improving overall detection efficiency while maintaining accuracy through subsequent verification.

Inventive Principle:

Principle #10Preliminary action

2Measurement precision

If in-depth detection using key data matching is performed, then detection accuracy is improved, but detection time increases

Engineering Contradiction:

Improvedetection accuracyVSAvoiddetection time

Core Design Contradiction:

Measurement precisionVSLoss of time

Solution Approach 1:

The first detection logic performs preliminary action by quickly matching feature values to identify potential infringements before the second detection logic conducts thorough key data verification. This preliminary screening filters out obvious non-infringements early, improving overall detection efficiency while maintaining accuracy through subsequent verification.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system applies partial action by using only feature values for the first detection logic when quick screening is sufficient, and reserves the more resource-intensive key data matching for the second detection logic only when needed. This approach avoids excessive computation for cases that can be resolved through simpler means.

Inventive Principle:

Principle #16Partial or excessive action

3Productivity

If a double-layer detection mechanism is implemented, then both efficiency and accuracy are improved, but system complexity increases

Engineering Contradiction:

Core Design Contradiction:

ProductivityVSDevice complexity

Solution Approach 1:

The detection process is segmented into two distinct layers: a first detection logic layer that performs rapid feature value matching for initial screening, and a second detection logic layer that performs comprehensive key data matching for accurate verification. This segmentation allows the system to achieve both speed and accuracy by applying appropriate detection methods at different stages.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The first detection logic is nested within the second detection logic, forming a hierarchical structure where the simpler feature value matching is contained within the more comprehensive key data verification framework. This nesting allows the system to maintain a unified detection flow while incorporating multiple levels of analysis.

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A blockchain-based infringement detection method includes: receiving a registration transaction initiated by a user, wherein the registration transaction includes key data of a work to be deposited and a contract address of a smart contract; invoking, in response to the registration transaction, a first detection logic declared in the smart contract corresponding to the contract address, extracting a feature value from work content of the work to be deposited, and matching the extracted feature value with a feature value of a deposited work in the blockchain; if the matching succeeds, further invoking a second detection logic declared in the smart contract corresponding to the contract address, matching the key data of the work to be deposited with key data of the deposited work in the blockchain, and when the matching succeeds, determining that the work to be deposited has an infringement risk.
