Digital Identity Verification via Attribute Extraction
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for verifying user identities often disclose unnecessary personal information, compromising privacy and security, as they rely on physical documents that reveal more information than required for business interactions.
Innovation Solution
A system and method where users provision digital identities to an identity host, which provides codes for verification, limiting or omitting personal identifying information (PII), allowing businesses to query attributes like age or insurance coverage without exposing sensitive details.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If physical documents are used to verify user identities, then verification reliability is improved, but unnecessary personal information is disclosed compromising privacy and security
Solution Approach 1:
The patent extracts only the necessary verification attributes from the complete personal information stored in the distributed ledger. When a business queries user credentials, the system retrieves and shares only the specific attributes required for verification (e.g., age, insurance coverage) while keeping other personal information private and stored locally in encrypted form.
Solution Approach 2:
The distributed ledger acts as an intermediary between users and businesses. Instead of users directly sharing personal documents with businesses, the ledger mediates the verification process by storing credentials and enabling businesses to query only necessary attributes through cryptographic proofs, preventing direct exposure of sensitive data.
2Reliability
If complete personal information is shared for verification, then verification completeness is improved, but information security deteriorates
Solution Approach 1:
The patent segments personal information into two categories: essential verification attributes stored in the distributed ledger for public querying, and sensitive personal information kept private and encrypted in local storage. This segmentation allows verification to proceed with only necessary data exposure.
Solution Approach 2:
Different parts of the information system have different access permissions and security levels. The distributed ledger contains publicly accessible verification attributes, while local user devices store encrypted sensitive information with restricted access. This local quality differentiation ensures that only necessary information is exposed during verification.
3Measurement precision
If physical documents are presented for verification, then identity confirmation is improved, but information overload occurs revealing more data than necessary
Solution Approach 1:
The system extracts and stores only the specific verification attributes needed for business interactions in the distributed ledger, separating them from other personal information. When verification is required, only these extracted attributes are shared, preventing information overload.

AI summary
Systems and methods are provided for use in responding to attribute queries related to identifying information for a user. One exemplary method includes receiving a request for an identity code for a user associated with identifying information, where the identifying information includes multiple attributes of the user, and generating the identity code and transmitting it to a computing device associated with the user. The method then includes receiving an identity request for the user from a requesting party including the identity code and at least one query related to at least one of the multiple attributes of the user, identifying the user based on the identity code, compiling a response to the at least one query based on the identifying information of the multiple attributes of the user, and transmitting the response to the requesting party.
