Blockchain Media Ledger for Secure Consumer Data Sharing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for sharing consumer data across different parts of a business are inadequate, vulnerable to data breaches, and result in ineffective or counterproductive targeted advertisements due to lack of a unified and secure view of consumer media consumption history.
Innovation Solution
A blockchain-based media ledger is used to create consumer profiles, record and manage media consumption history, and enable consumers to control access and share data securely with advertising networks through cryptographic tokens generated via a proof-of-engagement algorithm, allowing consumers to own and manage their data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If consumer data is stored in a shared database or integrated platform, then data sharing across business parts is improved, but security against data breaches deteriorates
Solution Approach 1:
The patent segments consumer data into discrete blockchain records that are distributed across multiple nodes rather than centralized in a single database. Each data point is stored as an immutable block in a decentralized ledger, eliminating the single point of failure while maintaining data accessibility across business units.
Solution Approach 2:
The blockchain acts as an intermediary layer between different business parts and consumer data. Instead of direct access to a shared database, all data requests must pass through the blockchain's consensus mechanism and cryptographic verification, providing security while enabling data sharing.
2Reliability
If consumer data is not shared across business parts, then data security is improved, but targeted advertising capability deteriorates
Solution Approach 1:
The blockchain-based media ledger serves multiple functions simultaneously: it secures consumer data through cryptographic methods, enables targeted advertising by sharing consumption history across business units, and provides consumer control through token-based access management. This multi-functionality resolves the contradiction between security and advertising effectiveness.
Solution Approach 2:
The system dynamically controls data access based on consumer preferences and token holdings. Consumers can adjust their data sharing settings at any time, and the system adapts by modifying access permissions accordingly, enabling both security and effective advertising under different conditions.
3Quantity of substance
If untargeted advertisements are displayed, then advertising reach is improved, but consumer satisfaction deteriorates
Solution Approach 1:
The system implements feedback loops where consumer media consumption history is continuously recorded on the blockchain and used to refine advertising targeting. This feedback mechanism ensures advertisements are relevant to consumer interests while maintaining broad reach, preventing consumer dissatisfaction from untargeted ads.

AI summary
Linking a consumption history of media to a consumer, including: creating a profile of the consumer using a blockchain-based media ledger; enabling the consumer to subscribe to advertisement networks; recording at least one of consumptions of the media and transactions by the consumer as a media consumption history on a content catalog of a digital right management (DRM); and ingesting the media consumption history into the blockchain-based media ledger from the content catalog of the DRM. Keywords include blockchain, advertising, cryptographic tokens, and DRM.
