Decentralized Identifier Attribution for Digital Content
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In conventional digital content scenarios, accurately attributing contributions from various entities involved in the creation of digital content is challenging due to non-standardized formats, leading to computational and data transfer inefficiencies, as existing methods often rely on an 'all or nothing' approach and struggle to identify specific contributors amidst similar names and roles.
Innovation Solution
The use of decentralized identifiers (DIDs) and verifiable credentials (VCs) to securely authenticate and validate the contributions of entities in a decentralized network, enabling precise attribution and standardization of contributions by associating unique identifiers with specific portions of digital content and using cryptographic proofs for validation.

Engineering Contradiction Analysis
1Measurement precision
If conventional methods are used to attribute contributions, then the system is simpler to implement, but the accuracy of contributor identification deteriorates due to non-standardized formats and similar names
Solution Approach 1:
The patent transforms contributor identification from using non-standardized format parameters to standardized parameters including decentralized identifiers (DIDs), verifiable credentials (VCs), and cryptographic proofs. This parameter transformation enables precise identification of contributors even with similar names by changing the identification space from ambiguous text strings to structured, verifiable data formats.
Solution Approach 2:
The patent introduces cryptographic proofs and verifiable credentials as intermediary elements between contributors and the attribution system. These intermediaries provide a standardized layer that verifies contributor identities and contributions, resolving the complexity of directly comparing non-standardized contributor data while maintaining high identification accuracy.
2Productivity
If an 'all or nothing' approach is used for contribution attribution, then the system is easier to operate, but the productivity is reduced due to inability to identify specific contributors
Solution Approach 1:
The patent segments the contribution attribution process into distinct components: individual contributor identification using DIDs, contribution verification using VCs, and cryptographic proof validation. This segmentation allows the system to process specific contributor attributions independently rather than requiring complete re-attribution of all contributions, thereby improving productivity while maintaining operational simplicity through modular processing.
Solution Approach 2:
The patent implements preliminary action by pre-issuing verifiable credentials to contributors and pre-establishing their decentralized identifiers before contributions are made. This preliminary setup enables rapid, automated attribution of specific contributions without requiring complex real-time verification, thus improving productivity while keeping the operational process simple through automated credential validation.
3Loss of information
If non-standardized formats are used for contributor data, then the device complexity is lower, but the loss of information increases due to computational and data transfer inefficiencies
Solution Approach 1:
The patent implements a universal data structure based on standardized formats (DIDs, VCs, cryptographic proofs) that serves multiple functions: identifying contributors, verifying their credentials, proving contribution authenticity, and enabling efficient data transfer. This multi-functional standardized structure eliminates information loss by ensuring consistent representation of contributor data across all system operations, while the modularity of the standard maintains manageable complexity.
Data Source
AI summary
A digital content contribution verification system in a decentralized network is described. In an implementation, digital content is obtained and a plurality of portions are located from the digital content. A decentralized identifier and verifiable credential are identified as associated with a respective portion of the plurality of portions. The decentralized identifier is resolvable to a respective node from a decentralized network of nodes individually configured to store, receive, and transmit data. Representations are displayed of the decentralized identifiers indicative of a respective entity and corresponding verifiable credentials validating a relationship of the respective entity with the respective portion.
