Distributed Ledger Content History Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing technique for charging fees for content exchanged over a peer-to-peer system fails to appropriately manage the history of content provided, making it vulnerable to tampering and unauthorized content distribution.
Innovation Solution
A control method executed by servers in a content management system that utilizes distributed ledgers to store transaction data, including identification information of the content provided, attribute values, date and time of provision, and violation information, ensuring secure and tamper-proof management of content history.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a peer-to-peer content exchange system is implemented, then content distribution efficiency is improved, but content history management reliability deteriorates
Solution Approach 1:
The patent introduces a third-party content management server as an intermediary between peer-to-peer content providers and consumers. This server centrally manages content history, tracks distribution, and maintains records of all content transactions, thereby ensuring reliable history management while preserving the efficient peer-to-peer distribution mechanism.
2Reliability
If centralized content management is used, then content history management reliability is improved, but system complexity increases
Solution Approach 1:
The patent segments the content management system into multiple functional modules: a content storage unit, a content management unit, a distribution management unit, and a history management unit. Each module handles specific tasks independently, which simplifies the overall system architecture while maintaining centralized control for reliable history management.
