Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing biometric systems for identity validation are insecure and inefficient, with biometric data being vulnerable to breaches and difficult for multiple entities to use effectively.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If biometric data is stored in centralized databases for identity validation, then identity verification can be performed, but the system becomes vulnerable to data breaches and security compromises
Solution Approach 1:
The patent segments biometric data into multiple components: original biometric templates are stored in a secure repository, while only hashed representations are stored in the distributed ledger. This segmentation allows identity validation without exposing the actual biometric data, resolving the contradiction between validation reliability and breach vulnerability.
Solution Approach 2:
The patent introduces cryptographic hash functions and digital signatures as intermediaries between the biometric data and the validation process. These intermediaries enable verification while maintaining security, as the hash values can be validated without revealing the original biometric information, thus protecting against data breaches while ensuring reliable identity validation.
2Object-affected harmful factors
If biometric data is encrypted and stored centrally, then data security is improved, but access and usage by multiple entities becomes difficult
Solution Approach 1:
The patent creates a universal system where hashed biometric data stored on a distributed ledger can be accessed and validated by multiple entities simultaneously. The hash-based approach allows any authorized entity to verify identity without requiring direct access to the encrypted original data, thus achieving both security and multi-entity accessibility.
Solution Approach 2:
The patent uses cryptographic hash copies of the biometric data instead of the original data itself. These hash copies can be freely distributed and accessed by multiple entities for validation purposes without compromising the security of the original biometric information stored in the secure repository.
3Reliability
If traditional biometric storage systems are used, then identity validation can be performed, but the systems are inefficient and difficult for multiple entities to use
Solution Approach 1:
The patent replaces traditional centralized mechanical storage and retrieval systems with a distributed ledger system using cryptographic operations. This substitution enables parallel access and validation by multiple entities simultaneously, dramatically improving validation efficiency while maintaining reliability through the decentralized architecture.
Data Source
AI summary
An apparatus for validating an identity of an individual based on biometrics includes a memory and a processor operatively coupled to a distributed database and the memory. The processor is configured to provide biometric data as an input to a predefined hash function to obtain a first biometric hash value. The processor is configured to obtain, using a first pointer to the distributed database, a signed second biometric hash value. The processor is configured to define a certification of the biometric data in response to verifying that a signature of the signed second biometric hash value is associated with the compute device and verifying that the first biometric hash value corresponds with the second biometric hash value. The processor is configured to digitally sign the certification using a private key associated with the processor to produce a signed biometric certification and store the signed biometric certification in the distributed database.
