Encoded Human-Readable Data With User-Controlled Blockchain Metadata
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user-centric computing systems lack a secure and user-controlled mechanism for generating, communicating, and managing human-discernible information with associated metadata, particularly in the context of Web3 technologies where users need to securely communicate using identifiers like telephone numbers and blockchain wallet addresses.
Innovation Solution
A system and method utilizing cryptography and blockchain technology to generate, register, and manage encoded human-readable data (EHRD) with user-controlled metadata, enabling secure communication by encoding human-discernible information such as telephone numbers and geolocation data on a blockchain, and using distributed hash tables for metadata lookup.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If human-discernible information is entered into a system, then the information can be processed and displayed, but the system controls the metadata information (font, text size, time-tag) instead of the user
Solution Approach 1:
The patent introduces a blockchain as an intermediary layer between the user and the system. User-controlled metadata is hashed and stored on the blockchain, creating a decentralized verification mechanism. This allows the system to verify user control without directly managing the metadata, resolving the contradiction between user control and system complexity.
Solution Approach 2:
The patent extracts the metadata control function from the central system and places it on the distributed blockchain ledger. By separating metadata management from system control, users gain control over their information's presentation attributes while the system focuses on core processing functions, reducing overall system complexity.
2Reliability
If cryptographic and blockchain technologies are used to enable user control over metadata, then user privacy and security are improved, but the system complexity and computational requirements increase
Solution Approach 1:
The patent segments the metadata into two parts: the original human-discernible information remains in the system, while the control metadata (font, size, timing) is hashed and stored on the blockchain. This segmentation allows cryptographic verification without requiring the entire system to implement full blockchain functionality, reducing complexity while maintaining reliability.
3Ease of operation
If metadata information such as font, text size, and time-tag is controlled by the system, then consistent display formatting is achieved, but users cannot retain control over their information's presentation
Solution Approach 1:
The patent implements preliminary hashing of user-controlled metadata before it reaches the display system. The hashed metadata is stored on the blockchain in advance, allowing the display system to verify and maintain formatting consistency through cryptographic proof without directly controlling the original metadata values. This preserves both user control and display stability.
Data Source
AI summary
An encoded human readable datum (EHRD) can be generated wherein the creator of the EHRD maintains control over the metadata associated with the EHRD. This metadata can be used to inform service providers how to send and receive communications with the owner of the EHRD. The metadata data associated with this EHRD can be updated. Controlling who can update the metadata associated with the EHRD is secured using cryptography, blockchain technology, or cryptography and blockchain technology.
