Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Current methods for sharing consumer data across different business parts are inadequate, leading to privacy issues and ineffective targeted advertising due to indiscriminate data collection and exploitation, as well as vulnerability to data breaches.

Innovation Solution

A blockchain-based media ledger system that enables consumers to control their data by generating a detailed profile, recording media consumption history, and allowing selective data sharing with advertisers and publishers, using cryptographic tokens for reward and access management.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If consumer data is collected and stored in a shared database for targeted advertising, then advertising effectiveness is improved, but data security and consumer privacy are compromised

Engineering Contradiction:

Improveadvertising effectivenessVSAvoiddata security

Core Design Contradiction:

ProductivityVSReliability

Solution Approach 1:

The patent introduces a blockchain-based media ledger as an intermediary between consumers and businesses. The ledger enables secure data sharing by allowing consumers to grant controlled access to their media consumption history without exposing raw personal data. Businesses can verify consumer identities and target advertisements effectively while the blockchain's cryptographic mechanisms protect consumer privacy and prevent unauthorized data access.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent segments consumer data access rights by allowing consumers to selectively share specific portions of their media consumption history with different businesses. The blockchain ledger stores segmented data access permissions, enabling consumers to grant access to certain data elements while maintaining privacy for others. This segmentation approach enables targeted advertising while preserving consumer privacy and security.

Inventive Principle:

Principle #1Segmentation

2Adaptability or versatility

If consumer data is shared across different business parts, then consumer recognition and targeted advertising are improved, but vulnerability to data breaches increases

Engineering Contradiction:

Improveconsumer recognitionVSAvoiddata breach vulnerability

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The blockchain-based media ledger acts as a secure intermediary that enables consumer recognition across different business parts without centralizing sensitive data. The ledger stores verified consumer identities and media consumption history in a distributed, cryptographically secured manner, allowing businesses to recognize and target consumers effectively while eliminating the single point of failure that makes centralized databases vulnerable to breaches.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the traditional centralized database mechanism with a blockchain-based distributed ledger system. This substitution uses cryptographic principles and distributed consensus mechanisms instead of centralized storage, fundamentally changing how consumer data is protected. The blockchain's immutable and decentralized nature provides inherent protection against data breaches while maintaining consumer recognition capabilities.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If indiscriminate consumer data collection is performed, then advertising targeting capability is improved, but consumer privacy is violated and user experience deteriorates

Engineering Contradiction:

Improveadvertising targeting capabilityVSAvoidprivacy invasion

Core Design Contradiction:

Measurement precisionVSObject-affected harmful factors

Solution Approach 1:

The patent introduces dynamic control over data sharing permissions, allowing consumers to adjust their privacy settings and data access grants in real-time. The blockchain ledger stores these dynamic permissions, enabling consumers to grant or revoke access to their media consumption history as desired. This dynamic approach enables precise advertising targeting when consumers permit it, while respecting their privacy choices when they prefer not to share data.

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system implements feedback mechanisms where consumers receive information about how their data is being used and can adjust their sharing preferences accordingly. The blockchain ledger tracks and verifies data access permissions, providing transparent feedback to consumers about which businesses have access to their information. This feedback loop enables consumers to make informed decisions about data sharing, balancing advertising targeting effectiveness with privacy protection.

Inventive Principle:

Principle #23Feedback

AI summary

Building and controlling access to a detailed profile of a consumer, including: generating the detailed profile of the consumer using a blockchain-based media ledger; enabling the consumer to subscribe to an advertisement network to control the access to the detailed profile of the consumer; recording consumptions and transactions of the consumer in the advertisement network as a media consumption history of the consumer; and ingesting the media consumption history into the blockchain-based media ledger. Keywords include blockchain, advertising, cryptographic token, and customer data.
