Solution Overview

Problem

Existing data processing systems lack timely and tamper-proof data transmission with privacy protection, especially in decentralized environments like blockchain networks.

Innovation Solution

Implementing a blockchain-based data processing method where service acceptance platforms and data processing entities use a distributed database to transmit and verify service processing results, ensuring data integrity and privacy through shared and private service processing results, with private data stored locally and shared data recorded on the blockchain.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If all data is recorded on the blockchain for transparency and verification, then data integrity and traceability are improved, but data privacy and security are worsened

Engineering Contradiction:

Improvedata integrityVSAvoiddata privacy exposure

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent segments service processing results into two distinct types: shared service processing results (recorded on blockchain) and private service processing results (stored locally). This segmentation allows the system to maintain data integrity through blockchain verification while protecting sensitive private data from exposure, directly resolving the contradiction between transparency and privacy.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent extracts private data from the blockchain recording system and stores it locally in private data storage units. Only non-sensitive shared results are extracted for blockchain recording, while private results remain excluded from the public ledger. This extraction approach maintains verification capability through shared data while removing privacy-exposing elements from the blockchain.

Inventive Principle:

Principle #2Taking out (Extraction)

2Object-affected harmful factors

If private data is stored locally rather than on blockchain, then data privacy is improved, but data verification and consensus are worsened

Engineering Contradiction:

Improvedata privacy protectionVSAvoiddata verification

Core Design Contradiction:

Object-affected harmful factorsVSReliability

Solution Approach 1:

The patent introduces shared service processing results as an intermediary between private data and blockchain verification. The shared results contain sufficient information for consensus verification and cross-entity validation without exposing sensitive private data. This intermediary mechanism enables verification while maintaining privacy protection.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements a feedback mechanism where service data processing entities verify shared service processing results recorded on the blockchain, and this verification information feeds back to confirm data integrity. The feedback loop ensures that even though private data is stored locally, its authenticity can be verified through the shared results and consensus mechanisms.

Inventive Principle:

Principle #23Feedback

3Adaptability or versatility

If service processing results are transmitted between entities, then service coordination is improved, but data transmission security and timeliness are worsened

Engineering Contradiction:

Improveservice coordinationVSAvoiddata transmission security

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent merges the advantages of centralized coordination and distributed verification by combining blockchain's immutable ledger with local private data storage. Service coordination is achieved through the shared results on blockchain, while data transmission security is maintained through local private storage and selective sharing, resolving the contradiction between coordination efficiency and transmission security.

Inventive Principle:

Principle #5Merging (Combining)

AI summary

A method and device for data processing based on a blockchain. The blockchain comprises a service acceptance platform node device and service data processing entity node devices. The method comprises: the service acceptance platform node device receives service processing application data of a target user; generating, on the basis of the service processing application data, a first shared service processing result and a first private service processing result with respect to a target service data processing entity; transmitting a first transaction to the blockchain, the first transaction comprising the first shared service processing result, thus allowing consensus verification of the first transaction by the blockchain and then included in a distributed database of the blockchain; and transmitting the first private service processing result to the target service data processing entity node device, thus allowing the target service data processing entity node device to generate a second service processing result on the basis of preset service processing steps.
