Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current document sharing methods, particularly in a digitized and remote work environment, are insecure and inconvenient, with blockchain technologies facing limitations in block size and cost, and existing solutions fail to enable secure sharing among a network of users effectively.
Innovation Solution
A network platform utilizing distributed ledger technology for secure document sharing, allowing issuers to define and manage credentials, holders to control access and duration, and 3rd parties to verify document origin with immutability, while enabling network growth and selective disclosure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain technology is used for document sharing, then security and verification are improved, but block size limitations and costs worsen
Solution Approach 1:
The patent segments the document verification system into two parts: cryptographic hashes and metadata are stored on the blockchain, while actual document content is stored off-chain in secure repositories. This segmentation allows the blockchain to provide verification security without being constrained by block size limitations, as only compact hash values and essential metadata need to be stored on-chain.
Solution Approach 2:
The patent introduces an intermediary layer consisting of secure document repositories and verification services that bridge the blockchain and document storage. These intermediaries handle the actual document content storage and retrieval, while the blockchain serves as a trusted verification layer that confirms document integrity and origin without directly storing large document files.
2Reliability
If cryptographic hashing and encryption are used for document sharing, then security is improved, but the ability to enable secure network effects among users worsens
Solution Approach 1:
The patent creates a universal document sharing platform that combines cryptographic security with network-wide verification capabilities. The system provides multiple functions: secure document storage, cryptographic verification, network-wide document validation, and controlled sharing permissions. This multi-functionality allows individual users to maintain security while participating in a broader network effect where all participants can verify and share documents securely.
Solution Approach 2:
The patent implements feedback mechanisms where the blockchain network provides real-time verification feedback on document authenticity and integrity. When a user shares a document, the network can immediately verify its cryptographic hash against the blockchain record, providing instant feedback on validity. This feedback loop enables secure network effects by allowing users to confidently share and verify documents across the network without manual verification processes.
3Measurement precision
If distributed ledger technology is used for document verification, then verification certainty is improved, but system complexity worsens
Solution Approach 1:
The patent implements self-service verification mechanisms where the system automatically performs cryptographic validation and document verification without requiring complex manual intervention. The distributed ledger technology operates autonomously to verify document hashes and maintain verification records, reducing the operational complexity despite the underlying technological sophistication. Users simply need to interact with standardized APIs and interfaces rather than managing complex verification processes.
Data Source
AI summary
A network platform for participants including at least one credential (document) holder, at least one credential issuer, and at least one 3rd party, for issuing credentials, managing a holder's digital credentials, and requesting and receiving credentials. The holder provides information relating to a credential to the issuer, and the issuer uses the information to define metadata of the credential and generate and issue a secure credential. The secure credential is maintained over a distributed ledger technology that creates redundancy and provides fidelity in the secure credential. The holder controls access to the secure credential by the at least one 3rd party over the network. The at least one 3rd party is granted access to at least a portion of the metadata in the credential by the holder. The secure credential provides verification of the at least a portion of the metadata to the at least one 3rd party that is granted access.
