Identity Profile Verification With Community-Blind Privacy
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing online communities face challenges in verifying the accuracy of user-provided personal identity details while ensuring user privacy and preventing unauthorized access to personal information.
Innovation Solution
A privacy-preserving identity verification service that generates a user's identity profile indexed by a unique identity profile identifier derived from a user identifier, community identifier, and nonce identification value, allowing users to control access and ensuring no single party can associate the user with a specific online community.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If user personal identity details are stored directly by the online community, then verification accuracy is improved, but user privacy is compromised
Solution Approach 1:
The system segments the identity verification process into multiple independent components: identity credentials are stored in a decentralized identity wallet rather than centralized community servers, and verification occurs through cryptographic proof without exposing underlying personal data. This segmentation allows verification accuracy while preserving user privacy through architectural separation of data storage and verification functions.
Solution Approach 2:
The patent introduces cryptographic intermediaries including zero-knowledge proofs and selective disclosure mechanisms that act as mediators between the user's identity credentials and the online community. These intermediaries enable verification of identity claims without revealing the actual personal identity details, thus maintaining both verification accuracy and user privacy through the intermediary cryptographic layer.
2Reliability
If user identity information is made accessible for verification, then verification reliability is improved, but unauthorized access risk increases
Solution Approach 1:
The system implements local quality by enabling selective disclosure of identity attributes based on specific verification contexts. Users can reveal only the necessary identity claims for each verification scenario while keeping other identity information private. This context-dependent disclosure maintains verification reliability for each specific case while minimizing exposure risk through localized information sharing.
Solution Approach 2:
The patent employs disposable cryptographic tokens and ephemeral verification credentials that are generated for specific verification purposes and then discarded. These short-lived cryptographic objects enable reliable verification without creating persistent copies of sensitive identity information, thereby reducing unauthorized access risk while maintaining verification reliability through purpose-limited credentials.
Data Source
AI summary
A method for privacy-preserving identity verification includes, at a computing node, receiving, over a computer network, a unique user identifier for a user within an online community, and a community identifier for the online community. An identity profile identifier is computer-generated based at least in part on the unique user identifier, the community identifier, and a nonce identification value. A network-accessible identity profile for the user is computer-generated, the identity profile including one or more verified identity claims for the user, and the identity profile indexed by the identity profile identifier.
