Multi-tier NFT Encryption for Secure Content Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional Non-Fungible Tokens (NFTs) fail to provide real benefits to owners as they do not offer exclusive access to digital content, relying on centralized authentication servers that are costly to maintain and compromise the security benefits of distributed blockchain technology.
Innovation Solution
A multi-tier encryption NFT system using distributed encryption and authentication technology, which splits multimedia content into multiple data portions, encrypts them, and allows decryption based on user tier levels, eliminating the need for centralized servers and ensuring data integrity and accessibility.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If centralized authentication servers are used to manage NFT access, then user access control can be implemented, but system cost and complexity increase significantly
Solution Approach 1:
The patent extracts the authentication function from centralized servers and embeds it directly into the NFT smart contract on the blockchain. Each NFT contains embedded authentication logic that automatically verifies user eligibility and grants access rights without requiring external server intervention, thereby eliminating the need for complex authentication server infrastructure while maintaining access control capabilities
Solution Approach 2:
The NFTs are designed to be self-authenticating through smart contracts that automatically verify user credentials and enforce access rules. The system enables self-service authentication where users present their credentials and the smart contract autonomously determines access rights, eliminating the need for centralized authentication servers to manually verify each user's eligibility
2Loss of information
If digital content is made publicly accessible, then content visibility is improved, but exclusive access benefits are lost
Solution Approach 1:
The patent implements local quality by encrypting digital content with multiple encryption layers where different portions or levels of content are accessible to different user tiers. The smart contract automatically decrypts and delivers appropriate content portions based on the user's NFT tier level, ensuring that each user receives exactly the level of access their tier entitles them to, thereby maintaining both broad accessibility and exclusive access control
Solution Approach 2:
The system employs dynamic access control where the NFT smart contracts automatically adjust content delivery based on real-time verification of user credentials and tier levels. The encryption and decryption process is dynamically controlled by the smart contract, which can grant or revoke access rights programmatically, enabling the system to adapt content accessibility to each user's specific entitlement without manual intervention
Data Source
AI summary
In certain embodiments, one aspect provides a method of securely distributing multi-tier multimedia contents on the Internet, using Non-Fungible Token (NFT) Blockchain and comprising the steps of: signal processing data splitting phase, converting an original multimedia file into multiple data portions; access control encryption phase, converting each of the multiple data portions into an encrypted data portion and uploading the encrypted data portion to a storage cloud; access control storage phase, storing the encrypted data portion on the storage cloud; access control decryption phase, downloading the encrypted data portion from the storage cloud and reconstructing each of the encrypted data portions into each of said multiple data portions; and signal processing data merging phase, reconstructing appropriate multimedia data content depending on a user's tier level.
