Solution Overview

Problem

Existing data sharing systems lack control over how user data is used, shared, and for how long, leading to potential misuse and loss of user control.

Innovation Solution

A data aggregator system segments user data into groups with separate access controls, incentivizes users, and uses smart contracts to enforce usage conditions and penalties for misuse.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If data is shared across multiple computer systems, then data value and customization capability are improved, but user control over data usage is lost

Engineering Contradiction:

Improvedata customization capabilityVSAvoiduser control over data

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The patent segments user data into multiple categories (e.g., demographic data, behavioral data, transactional data) and encrypts each category with separate keys. This allows the system to share specific data segments with different parties while maintaining user control through selective disclosure and granular access management.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The patent introduces a data aggregator system as an intermediary between users and data consumers. This intermediary manages encryption keys, facilitates selective data sharing, and enforces usage conditions, thereby maintaining user control while enabling data value realization across multiple systems.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Productivity

If data is shared beyond user device, then data utilization is improved, but data security and misuse prevention are worsened

Engineering Contradiction:

Improvedata utilizationVSAvoiddata misuse risk

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent applies preliminary encryption to data before it leaves the user device. Data is encrypted with user-specific keys before sharing, and usage conditions are established in advance through smart contracts. This preliminary security measure prevents misuse while allowing data utilization.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The patent implements feedback mechanisms through smart contracts that monitor data usage and automatically enforce penalties or revoke access when misuse conditions are detected. This feedback loop enables continuous security monitoring while maintaining data utilization capabilities.

Inventive Principle:

Principle #23Feedback

3Quantity of substance

If data is shared across multiple systems, then data value is improved, but control over data usage duration and redistribution is lost

Engineering Contradiction:

Improvedata valueVSAvoiddata usage duration control

Core Design Contradiction:

Quantity of substanceVSDuration of action of stationary object

Solution Approach 1:

The patent employs dynamic access control mechanisms where data sharing permissions are time-bound and condition-based. Usage duration and redistribution rights are programmatically controlled through smart contracts that can automatically expire or modify access rights, enabling flexible control over data lifecycle.

Inventive Principle:

Principle #15Dynamics

AI summary

Techniques for controlling access to segmented data of a plurality of users that is requested by at least one data consumer device. In response to conditions specified in communications between at least one data aggregator system and the at least one data consumer device, information of a number of users meeting specified search criteria are shared (e.g., for a limited time). Use of the data in violation of the specified conditions may trigger penalties under a smart contract on a distributed ledger or blockchain.
