Dummy Identifier Mediation for Private Data Exchange Arbitration

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing data exchange systems face challenges in securely exchanging personal information between data providers and consumers while preventing name identification and ensuring charging arbitration.

Innovation Solution

An information processing device mediates data exchange by issuing and managing dummy identifiers for data consumers and providers, enabling secure data requests and responses without revealing actual user identities, and managing ticket states for error handling and charging.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If actual user identifiers are transmitted between data provider and consumer, then data exchange can be performed, but user privacy and security are compromised due to name identification risks

Engineering Contradiction:

Improvedata securityVSAvoiduser privacy

Core Design Contradiction:

ReliabilityVSLoss of information

Solution Approach 1:

The patent introduces a platform as an intermediary that issues dummy user identifiers to both data consumers and data providers. These dummy identifiers serve as mediators that enable data exchange without exposing actual user identities. The platform maps dummy identifiers to real user identifiers internally, allowing secure data transmission while preventing name identification between trading parties.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent creates dummy user identifiers that are copies or representations of actual user identifiers. These dummy identifiers replicate the functional need for user identification in data exchange processes while being decoupled from the actual personal information, thus enabling data transmission without compromising user privacy.

Inventive Principle:

Principle #26Copying

2Reliability

If dummy identifiers are used to protect user privacy, then name identification is prevented, but charging arbitration becomes difficult

Engineering Contradiction:

Improveuser privacy protectionVSAvoidcharging arbitration

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent implements a feedback mechanism where the platform monitors and tracks data exchange operations using dummy identifiers. This feedback system enables the platform to record which dummy identifiers are used for what purposes, allowing subsequent charging arbitration based on the tracked usage patterns while maintaining user privacy protection throughout the process.

Inventive Principle:

Principle #23Feedback

AI summary

The information processing device transmits a first identifier in response to a user identifier issuance request transmitted from a data consumer, transmits a second identifier in response to a user identifier issuance request transmitted from a data provider, and transmits data. Receiving from the consumer a ticket issuance request including information specifying user data requested by the data consumer, a first identifier, and a data provider to which the request is made, and issuing and issuing a data request ticket corresponding to the ticket issuance request the ticket identifier of the received data request ticket is sent to the data consumer, and when the ticket identifier is received from the data provider, the data request ticket corresponding to the ticket identifier is sent to the data provider.
