Digital Media Token Linking for Controlled NFT Derivative Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for tokenizing digital media files and their derivatives fail to provide a technical solution for managing the transfer of non-fungible tokens associated with original and derivative files effectively.
Innovation Solution
A blockchain-based platform manages digital media files by associating a cryptographic token with an original file and a set of derivative files, using smart contracts to control the transfer of non-fungible tokens (NFTs) to designated wallet addresses, ensuring the initial transfer of the original file's token is limited to specific NFT owners.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If an original digital media file is tokenized and derivative files are created and tokenized via non-fungible tokens, then the ability to manage and transfer ownership of digital media assets is improved, but the complexity of managing transfer restrictions and associations between original and derivative files increases
Solution Approach 1:
The patent implements a nested token structure where derivative file tokens are embedded within or associated with the original file token. The original digital media file token contains or references a set of derivative file tokens, creating a hierarchical relationship. This nesting approach allows the system to manage complex ownership relationships while maintaining a unified control mechanism at the original file level, reducing the apparent complexity for users.
Solution Approach 2:
The patent segments the ownership management into distinct components: the original file token and separate derivative file tokens. Each token type has specific functions and transfer rules. The original file token manages the master copy and its associations with derivatives, while derivative tokens manage individual derivative files. This segmentation allows for specialized control mechanisms for each token type, improving overall system adaptability while organizing complexity into manageable segments.
2Reliability
If the transfer of the first cryptographic token is limited to designated wallet addresses of NFT holders, then the security and control over digital media file distribution is improved, but the ease of transferring the token is reduced
Solution Approach 1:
The patent implements preliminary action by pre-designating and storing the set of authorized wallet addresses (NFT holders) within the original file token's metadata or associated data structure during the tokenization process. These designated addresses are registered in advance, creating an authorized recipients list. When a transfer is initiated, the system automatically checks against this pre-established list, eliminating the need for manual authorization checks and simplifying the transfer process while maintaining security.
3Loss of information
If a logical association between derivative files and the original digital media file is stored in memory, then the ability to track and manage derivative relationships is improved, but the memory storage requirements and data management complexity increase
Solution Approach 1:
The patent implements copying by storing the association relationship between derivative files and the original file in the metadata of each individual derivative file token. Each derivative token contains a reference or copy of the association data pointing back to the original file token identifier. This distributed copying approach eliminates the need for a centralized large-scale storage structure, as each token independently carries its relationship information, reducing overall system storage requirements while maintaining complete relationship tracking capability.

Managing digital media files in a computer network by storing a set of derivative files and a logical association of the derivative files with the first digital media file; generating a first cryptographic token; associating the first cryptographic token with the first digital media file; associating the first cryptographic token with a first wallet address corresponding to a first wallet; generating a serialized set of non-fungible tokens and associating individual ones of the non-fungible tokens with individual ones of the derivative files; and associating individual ones of the non-fungible tokens with individual wallet addresses of a second set of wallets; and limiting the initial transferability of the first cryptographic token from the first wallet to one of the second set of wallets.
