Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centralized databases face issues such as single points of failure, dependency on network connectivity, bottlenecks during high traffic, and challenges in tracking media access and rights within peer-to-peer networks, which hinder efficient media storage and access.
Innovation Solution
A blockchain-based system that divides files into chunks, stores them on multiple nodes, and uses smart contracts for permissioned access, ensuring immutability, security, and decentralized storage, allowing for seamless media access and rights management on a peer-to-peer network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If a centralized database is used to store data at one location, then data redundancy is minimized and management is simplified, but the system has a single point of failure and is highly dependent on network connectivity
Solution Approach 1:
The patent divides the centralized database into multiple distributed nodes across a peer-to-peer network. Each node stores portions of the data, eliminating the single point of failure while maintaining data integrity through cryptographic hashing and consensus mechanisms.
Solution Approach 2:
The patent introduces blockchain technology as an intermediary layer that coordinates data storage and access across distributed nodes. Smart contracts automatically manage data placement, retrieval, and access control without requiring centralized management.
2Ease of operation
If all data is stored in a single centralized location, then data access control is simplified, but bottlenecks occur during high traffic and access speed decreases
Solution Approach 1:
The patent segments data into multiple chunks distributed across numerous peer-to-peer nodes. This allows simultaneous access from multiple locations without creating bottlenecks, as users can retrieve data from any node that holds the required chunks.
Solution Approach 2:
The patent transitions from a single-dimensional centralized storage model to a multi-dimensional distributed network architecture. Data can be accessed through multiple pathways and nodes simultaneously, dramatically increasing throughput and eliminating single-point bottlenecks.
3Quantity of substance
If data is stored in a centralized database with minimal redundancy, then storage efficiency is improved, but data loss is difficult to retrieve and fault tolerance is reduced
Solution Approach 1:
The patent implements different quality levels for different portions of data across the distributed network. Critical data chunks are replicated across multiple nodes with varying redundancy levels, while less critical data uses more efficient storage. This local differentiation optimizes both storage efficiency and recovery capability.
Solution Approach 2:
The patent employs cryptographic hashing and redundant data chunks distributed across multiple nodes before any data loss occurs. This preemptive approach ensures that if any node fails, the data can be reconstructed from remaining nodes without manual intervention or backup restoration.
4Productivity
If media content is shared on a public P2P network, then seamless access and reduced governing costs are achieved, but tracking media access and rights management becomes challenging
Solution Approach 1:
The patent implements a feedback mechanism where each data access, transfer, and modification event is automatically recorded on the blockchain. This creates an immutable audit trail that tracks media usage throughout the P2P network, enabling accurate rights management and royalty distribution while maintaining seamless user access.
Solution Approach 2:
The patent uses smart contracts as intermediaries between content owners and users. These automated contracts enforce licensing terms, track usage, and manage rights without requiring manual monitoring, combining the efficiency of public P2P sharing with accurate rights management.

AI summary
An example operation may include one or more of receiving a request to access a file from a user node, by a file processor node, generating, by the file processor node, a file storage plan based on a distribution of file chunks throughout a peer-to-peer network, authenticating, by the file processor node, the user node based on blockchain credentials, acquiring, by the file processor node, a permission to access the file from a file owner node, and sending the file storage plan to the user node.
