Immutable Digital Identity Token for Secure Biometric Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital identity systems expose personal information, making them vulnerable to identity theft and fraud, and they often require access to governmental systems for verification, which is inefficient and insecure.
Innovation Solution
A system that creates and stores a unique digital identity associated with an individual using a capture device to gather biometric and identification information, which is then verified through a third-party system and stored on an immutable ledger, allowing for secure authentication without exposing personal information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If personal information is published on digital identity tokens, then verification and authentication can be performed, but the risk of identity theft and fraud increases
Solution Approach 1:
The patent extracts only the essential verification data (name, date of birth, unique identifier) from the full personal information set and publishes only these minimal necessary fields on the blockchain token. The complete personal information remains secured in the governmental database, separated from the public-facing identity token. This extraction principle resolves the contradiction by providing sufficient verification data while minimizing exposure of sensitive information.
Solution Approach 2:
The patent applies different quality levels to different parts of the identity system: the blockchain token contains minimal published information with high accessibility, while the governmental database contains complete personal information with restricted access. Each layer serves its specific function with appropriate information density, resolving the contradiction between verification needs and security requirements.
2Measurement precision
If governmental systems are accessed for verification, then accurate identity verification can be performed, but system complexity and access time increase
Solution Approach 1:
The patent performs the complex governmental verification process in advance during token creation. The governmental system verifies the individual's identity and issues the blockchain token with embedded verification data before the actual verification need arises. This preliminary action stores the verification result on the immutable blockchain, eliminating the need for repeated complex governmental system access while maintaining verification accuracy.
Solution Approach 2:
The patent creates a simplified copy of the governmental verification data on the blockchain that can be easily accessed and verified without requiring connection to the complex governmental system. The blockchain token serves as a portable, self-contained verification copy that preserves the accuracy of governmental verification while eliminating system access complexity.
3Adaptability or versatility
If complete personal information is stored digitally, then comprehensive identity verification is possible, but vulnerability to data breaches and fraud increases
Solution Approach 1:
The patent extracts only the specific data elements necessary for identity verification (name, date of birth, unique identifier) and places them on the blockchain token. Complete personal information including social security numbers, addresses, and other sensitive data remain in the secured governmental database. This extraction resolves the contradiction by providing verification flexibility with extracted fields while maintaining data security through minimal exposure.
Solution Approach 2:
The blockchain token serves as an intermediary between the governmental database and external verification systems. It provides a secure middle layer that enables verification flexibility through programmable smart contracts while protecting the complete personal information in the governmental database from direct exposure to external systems.
Data Source
AI summary
The present system can include the ability to create and store a unique digital identity of an individual. The system can include an generation server and an immutable storage system. An identity capture device can be adapted to: receive a first biometric information from the identity capture device, create a digital identity record according to the first biometric information, store the digital identity record on the immutable storage system, create a digital envoy according to the digital identity record wherein the digital envoy is uniquely associated with the digital identity record, wherein the digital envoy is adapted to be provided to an authentication system wherein the authentication system is adapted to receive a second biometric information, receive the digital envoy, retrieve the digital identity record, and create an authentication approval according to a positive comparison of the digital identity record and the second biometric information.
