Media Wallet Data Privacy via Segmented Blockchain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blockchain-based systems lack user control over data privacy and do not adequately reward users for their consumption data, leading to concerns about user privacy and the exploitation of consumer activity metadata.
Innovation Solution
A blockchain-based content engagement platform that enables verified content creators to mint Non-Fungible Tokens (NFTs) and uses media wallet applications to securely store and manage user data, allowing users to grant fine-grained permissions for data access and offering incentives in the form of tokens for sharing consumption data.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain-based systems are used to record transactions and data, then data permanence and verifiability are improved, but user control over data privacy deteriorates
Solution Approach 1:
The patent segments data storage by creating separate chains: a public blockchain for immutable transaction records and a private blockchain for sensitive user data. This allows the system to maintain data permanence on the public chain while preserving user privacy by storing sensitive information on the private chain accessible only to authorized participants.
Solution Approach 2:
The patent introduces a permissioned intermediary layer between users and the public blockchain. This intermediary system manages data access rights and enables users to share data selectively with specific organizations or for specific purposes, thereby maintaining privacy while allowing controlled data utilization.
2Productivity
If users share consumption data with content creators, then content creators can incentivize users with tokens, but users lose control over their personal information
Solution Approach 1:
The patent implements dynamic data sharing through programmable data rights that can be created, modified, and revoked. Users can grant temporary or permanent access to specific datasets for specific purposes, and these rights can be dynamically adjusted or revoked at any time, ensuring continuous user control over their information.
Solution Approach 2:
The system incorporates feedback mechanisms where users receive token rewards based on their data sharing decisions. This feedback loop incentivizes users to share data when they choose, while the system tracks and respects user preferences, creating a balanced ecosystem where both users and content creators benefit.
3Productivity
If permissioned blockchains are used with preapproved entities, then transaction validation efficiency is improved, but system accessibility deteriorates
Solution Approach 1:
The patent creates a multi-chain system where the public blockchain serves multiple functions: recording transactions, managing NFTs, and enabling decentralized finance operations. This universal platform can be accessed by anyone while maintaining efficient validation through permissioned private chains for specific high-value transactions.

AI summary
Systems and methods are described for implementing blockchain-based content engagement platforms. In several embodiments, the content engagement platform includes a registry service which enables verified content creators to mint Non-Fungible Tokens (NFTs). In many embodiments, media wallet applications enable users to securely store NFTs and/or other tokens on their devices. In a number of embodiments, the media wallet applications collect data concerning media consumed by users and aggregate the media consumption data in a permissioned analytics blockchain. The manner in which the media consumption data is stored can enable users to control permission to access their personal data. In one embodiment, a media wallet is provided that can securely store NFTs, display a user interface through which user instructions concerning data access permissions are received, and cause media consumption data to be written to at least one immutable ledger in conjunction with a set of data access permissions.
