Solution Overview

Problem

Current systems for trading privacy information lack the ability for information providers to selectively choose purchasers and limit the scope of information sold, leading to potential misuse and a lack of transparency in transactions, affecting both individuals and businesses.

Innovation Solution

A system and method utilizing an intermediary server that distributes and stores privacy information in a blockchain, allowing information providers to select and limit the scope of privacy information sold through a purchase information list, enabling them to choose legitimate purchasers and receive appropriate rewards based on the scope of information shared.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If privacy information is traded through brokerage agencies, then transactions can be facilitated, but information providers cannot control the scope or verify legitimate use of their information

Engineering Contradiction:

Improveease of privacy information transactionVSAvoidreliability of information usage control

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent introduces a blockchain-based intermediary system that mediates between information providers and purchasers. The blockchain platform acts as a trusted third party that enables direct transactions while maintaining transparency and control, allowing providers to specify usage scope and purchasers to verify legitimacy through smart contracts without relying on traditional brokerage agencies.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The system implements feedback mechanisms where information providers can track and verify how their privacy information is being used through the blockchain ledger. The transparent recording of transactions and usage patterns provides continuous feedback to providers, enabling them to monitor compliance with agreed-upon scope and take action if misuse occurs.

Inventive Principle:

Principle #23Feedback

2Productivity

If privacy information is sold without selective control, then information providers can easily monetize their data, but the information may be misused or accessed indiscriminately

Engineering Contradiction:

Improveproductivity of privacy information monetizationVSAvoidharm from indiscriminate information access

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent implements dynamic control mechanisms where information providers can adjust the scope, duration, and conditions of their privacy information usage rights in real-time through smart contracts. This dynamic approach allows providers to monetize their data effectively while maintaining the ability to restrict access and revoke permissions as needed, preventing indiscriminate use.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system allows information providers to change parameters such as usage scope, time period, and purchaser qualifications through smart contract configurations. By enabling parameter changes, the system facilitates flexible monetization while maintaining control mechanisms that prevent harmful indiscriminate access to privacy information.

Inventive Principle:

Principle #35Parameter changes

3Speed

If information purchasers use privacy information without verification, then advertising campaigns can be launched quickly, but the effectiveness and legality of advertising cannot be ensured

Engineering Contradiction:

Improvespeed of advertising campaign deploymentVSAvoidprecision of advertising effectiveness measurement

Core Design Contradiction:

SpeedVSMeasurement precision

Solution Approach 1:

The patent implements preliminary verification through smart contracts that automatically validate purchaser credentials and advertising campaign parameters before execution. This preliminary action ensures that only legitimate purchasers with proper authorization can access and use privacy information for advertising, while maintaining quick deployment through automated verification processes.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The blockchain system provides real-time feedback on advertising campaign performance and information usage patterns. This feedback mechanism enables precise measurement of advertising effectiveness while ensuring compliance with privacy agreements, allowing purchasers to track usage metrics and providers to verify legitimate use throughout the campaign duration.

Inventive Principle:

Principle #23Feedback
