Secure Document Authentication Using Location Confidence Matching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication systems struggle to accurately verify the identity of a user providing an identification document, leading to resource wastage due to incorrect authentication determinations by malicious actors.
Innovation Solution
A system that uses a secure document with location information and device location to determine a confidence score, comparing document appearance parameters with a live user image and device location to authenticate access attempts.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication methods are used to verify user identity, then authentication can be performed, but resource wastage occurs due to incorrect authentication determinations by malicious actors
Solution Approach 1:
The patent introduces location information as an additional verification dimension beyond traditional document verification. By comparing device location with location embedded in the document's digital signature, the system creates a spatial dimension for authentication that helps distinguish legitimate users from malicious actors presenting stolen documents, thereby improving reliability without proportionally increasing resource consumption.
Solution Approach 2:
The system changes the authentication parameters from solely document-based verification to a composite verification including location data. By incorporating location as a dynamic parameter that must match between device and document, the system enhances authentication accuracy while maintaining efficient resource usage through automated comparison algorithms.
2Reliability
If location-based verification is added to authentication, then authentication accuracy improves, but system complexity increases
Solution Approach 1:
The patent leverages the device's existing location capabilities (GPS, network location services) that are already present in modern smartphones and computers. By repurposing these existing multi-functional components for authentication purposes, the system avoids adding dedicated hardware or complex subsystems, thus improving reliability while minimizing increases in system complexity.
Solution Approach 2:
The system embeds location information into the document's digital signature structure, creating a copy of the location data that can be verified without requiring continuous access to the original document or complex verification infrastructure. This copying approach simplifies the verification process while maintaining high authentication accuracy.

AI summary
In some implementations, a device may obtain, from a user device, a document image that depicts location information associated with an owner of the document. The device may obtain location information associated with the user device. The device may perform optical character recognition using the document image to obtain a location, or may scan a machine-readable code depicted in the document image to obtain the location. The device may determine a device location based on the location information. The device may determine a confidence score based on the location and the device location. The device may determine whether the confidence score satisfies a threshold. The device may perform an action based on determining whether the confidence score satisfies the threshold.
