Biometric Hash Credential Recovery via Noise-Resistant Transformation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional systems for secure data retrieval face challenges in accessing credentials due to the loss of master credentials or devices, especially when biometric data is not stored in a hashed format, leading to irreparable harm in financial, physical, and reputational aspects, especially with the rise of IoT devices.
Innovation Solution
A method for generating a hash of a biometric measurement using a noise-resistant feature transformation and hashing module, allowing secure data recovery without storing raw biometric data, using error correcting codes and hashing algorithms to ensure secure access to credentials across different devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If biometric data is stored in clear or unsecured format for easy access, then ease of operation is improved, but security is worsened
Solution Approach 1:
The patent transforms biometric data from clear text to hashed format, changing the parameter of data representation. This allows the system to maintain security while enabling authentication through hash comparison rather than storing raw biometric data
Solution Approach 2:
The patent introduces hash functions as an intermediary between biometric data and credential access. Instead of directly storing or comparing raw biometric data, the system uses hashed representations as a mediator, achieving both security and functionality
2Reliability
If credentials are stored on a single device with master credential protection, then security is improved, but adaptability is worsened
Solution Approach 1:
The patent extracts the binding between credentials and specific devices by using biometric hashes as the foundation. Credentials can be stored on multiple devices without requiring the master credential or original device, separating the authentication mechanism from device-specific constraints
Solution Approach 2:
The patent creates a universal authentication system where biometric hashes serve as a device-agnostic credential. The same biometric hash can authenticate across multiple devices and platforms, making the system universally accessible without compromising security
3Reliability
If complex recovery processes are implemented for lost credentials, then security is improved, but ease of operation is worsened
Solution Approach 1:
The patent performs preliminary hashing of biometric data during enrollment, creating a reusable authentication key. This preliminary action eliminates the need for complex recovery processes later, as the hashed biometric data can be directly used for authentication on any device
