Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems lack efficient methods for managing content ownership using decentralized networks, particularly in blockchain environments, where centralized servers are unnecessary.
Innovation Solution
An electronic device equipped with a communication module, memory, and processor is used to identify content ownership, transfer ownership via a blockchain network, encrypt content using a public key, and transmit encrypted content to an external device, facilitating ownership management through a decentralized network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a centralized server is used to manage content ownership, then decision making is centralized and simplified, but a single point of failure and security risk is created
Solution Approach 1:
The patent segments the centralized ownership management function into distributed nodes across a blockchain network. Each node maintains a copy of the ownership ledger, eliminating the single point of failure inherent in centralized systems while distributing decision-making authority across multiple participants through consensus mechanisms.
Solution Approach 2:
The patent introduces a smart contract as an intermediary that automatically executes ownership transfer logic when conditions are met. This mediator eliminates the need for trusted centralized servers while ensuring reliable and transparent ownership management through coded rules that all participants can verify.
2Reliability
If a decentralized blockchain network is used to manage content ownership, then security and trust are improved, but transaction complexity and computational overhead increase
Solution Approach 1:
The patent implements self-service through smart contracts that automatically verify and execute ownership transfers without requiring manual intervention or complex coordination between nodes. The automated verification processes reduce transaction complexity while maintaining the security benefits of decentralized validation.
Solution Approach 2:
The patent optimizes blockchain transaction parameters by implementing efficient data structures for ownership records and using compressed encryption methods. These parameter changes reduce the computational overhead and transaction complexity while preserving the security and immutability characteristics of the blockchain network.
3Reliability
If content is encrypted using public key cryptography, then security is improved, but processing time and computational resources increase
Solution Approach 1:
The patent segments the encryption process by applying different cryptographic methods to different parts of the content. Critical metadata and ownership information receive strong encryption, while less sensitive portions use lighter encryption schemes, optimizing the balance between security and processing time.
Solution Approach 2:
The patent performs preliminary encryption of content before it is uploaded to the blockchain network. This advance preparation reduces the computational burden during transaction processing, as the content is already encrypted and ready for secure storage without requiring real-time cryptographic operations during ownership transfers.
