Biometric Identity Verification via Non-Reconstructible Templates
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current biometric identification systems within coalitions are vulnerable due to the lack of shared biometric information between countries, making it difficult to verify the identity of soldiers, leading to potential infiltration and reduced security.
Innovation Solution
The International Biometric Identification System (IBIS) uses non-reconstructible biometric templates and Public Key Infrastructure (PKI) certificates to verify the authenticity of tactical devices between nations, allowing each country to maintain control over their biometric data and verification processes without sharing actual biometric information, using devices like laptops or tablets for mobile verification.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If nations share biometric information to verify soldier identities, then identification security is improved, but data security and sovereignty are compromised
Solution Approach 1:
The system divides the centralized biometric database into distributed national databases, with each coalition nation maintaining control of their own biometric data. The verification process is segmented into local template matching operations that occur within each nation's own system, eliminating the need to centralize sensitive biometric information while still enabling cross-nation verification.
Solution Approach 2:
The patent introduces encrypted template representations and secure communication protocols as intermediaries between nations. Instead of sharing raw biometric data, nations exchange encrypted template hashes that can be verified without revealing the underlying biometric information. This intermediary layer enables verification while protecting data sovereignty.
2Object-affected harmful factors
If nations do not share biometric information, then data security is maintained, but identification verification reliability deteriorates
Solution Approach 1:
The system creates and distributes encrypted copies of biometric templates to coalition partners' verification devices. These template copies are mathematically derived from the original biometric data but cannot be reverse-engineered to reveal the source information. The copies enable verification operations abroad while the original biometric data remains securely stored in the home nation's database.
Solution Approach 2:
The patent transforms biometric data from its original form into mathematical templates with different parameter representations. These templates use transformed parameter spaces (such as frequency domain representations or geometric feature vectors) that maintain verification capability while eliminating direct identifiability. The parameter transformation ensures that even if templates are compromised, the original biometric information cannot be recovered.
3Device complexity
If physical ID cards are used for verification, then device complexity is reduced, but security against counterfeiting increases
Solution Approach 1:
The patent replaces physical ID cards and manual verification processes with electronic biometric template matching systems. Instead of visually inspecting physical documents that can be forged, the system uses digital template comparison algorithms that provide cryptographic verification of identity. This substitution eliminates counterfeiting vulnerabilities while maintaining verification capability through software-based processes.
Data Source
AI summary
A system and method for international biometric identity verification between two countries; without transferring biometric information between the two countries. The system and method will replace the traditional approach of identification of uniforms and identification cards, which are easily compromised, into a secure approach of leveraging biometric information through a person's identity. This system and method are consistent with the policy of not sharing any biometric information relating to verification of identification of individuals with other countries.
