Decentralized Identity Verification via Granular KYbit Tokens
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional identity verification methods expose individuals to privacy risks by requiring excessive personal data disclosure, lack user control over data sharing, and rely on centralized systems prone to breaches, with inefficiencies and interoperability challenges across platforms.
Innovation Solution
A decentralized identity verification system using blockchain technology generates secure, granular identity tokens (KYbits) that encapsulate specific attributes, allowing users to control data sharing and ensuring privacy through a public-private key framework, with components like digital wallets and physical authentication tokens for secure access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional identity verification methods are used, then verification can be completed, but excessive personal data is disclosed and privacy is compromised
Solution Approach 1:
The patent segments identity information into discrete, granular attributes (e.g., age, nationality, profession) that can be independently verified and shared. Instead of disclosing complete identity documents, the system allows selective disclosure of specific attributes through decentralized identity tokens, thereby reducing privacy risk while maintaining verification reliability.
Solution Approach 2:
The patent extracts only the necessary identity attributes required for verification purposes from complete identity documents. Through selective disclosure mechanisms, the system extracts and shares minimal necessary information (e.g., only age verification without revealing full birth date or other sensitive details), eliminating excessive data exposure while preserving verification effectiveness.
2Ease of operation
If centralized databases are used for storing personal information, then identity management is simplified, but security vulnerabilities and single points of failure are introduced
Solution Approach 1:
The patent segments the centralized identity management system into distributed identity tokens stored across multiple decentralized nodes. Each user's identity attributes are represented as independent tokens that can be selectively shared without requiring a central repository, eliminating single points of failure while maintaining operational simplicity through standardized token interfaces.
Solution Approach 2:
The patent implements self-service mechanisms where users independently manage their own identity tokens through digital wallets and authentication devices. Users can selectively disclose attributes, revoke access, and control their own data without relying on centralized authorities, thereby enhancing both security and user autonomy while simplifying identity management operations.
3Object-affected harmful factors
If selective disclosure techniques are implemented, then data security is improved, but system complexity increases and user control is limited
Solution Approach 1:
The patent creates universal identity tokens that can be used across multiple verification contexts and platforms. The standardized token structure and verification protocols enable the same technical mechanism to serve diverse verification needs (age verification, identity confirmation, attribute validation) without requiring separate complex systems for each use case, thereby reducing overall system complexity while maintaining strong security.
Solution Approach 2:
The patent implements self-service mechanisms where users independently manage their own identity tokens through digital wallets and authentication devices. Users can selectively disclose attributes, revoke access, and control their own data without relying on centralized authorities, thereby enhancing both security and user autonomy while simplifying identity management operations.
4Measurement precision
If complete identity information is shared for verification, then verification accuracy is ensured, but data minimization principle is violated and privacy is compromised
Solution Approach 1:
The patent segments identity information into discrete, granular attributes (e.g., age, nationality, profession) that can be independently verified and shared. Instead of disclosing complete identity documents, the system allows selective disclosure of specific attributes through decentralized identity tokens, thereby reducing privacy risk while maintaining verification reliability.
Solution Approach 2:
The patent extracts only the necessary identity attributes required for verification purposes from complete identity documents. Through selective disclosure mechanisms, the system extracts and shares minimal necessary information (e.g., only age verification without revealing full birth date or other sensitive details), eliminating excessive data exposure while preserving verification effectiveness.
Data Source
AI summary
Approaches are described for secure identity verification using blockchain technology. A configuration record for a user's identity attributes is obtained. The configuration record is used to evaluate and verify various identity elements through cross-referencing with authoritative sources. Based on the configuration record, identity tokens (KYbits) are generated using cryptographic techniques and stored on a blockchain ledger. These KYbits encapsulate verified identity information and can be utilized in verification processes without disclosing sensitive personal data. The identity tokens enable secure and privacy-preserving transactions across various platforms, ensuring compliance with data protection regulations and enhancing user control over personal identity information.
