Current digital identity verification systems are insecure and unverifiable, susceptible to identity theft and falsification, relying on government-issued documents that can be easily counterfeited, leading to issues like identity theft and fraudulent activities.
Innovation Solution
A system that creates a secure and verifiable digital identity using user-generated items with identifiable features, stored on a blockchain, where devices with immutably tied private keys certify and validate user identities through cross-confirmation and biometric verifications, eliminating the need for centralized issuers.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If government-issued documents are used for identity verification, then verification can be performed with existing infrastructure, but the system becomes susceptible to counterfeiting and identity theft
Solution Approach 1:
The patent uses cryptographic hashing to create a digital copy of the identity verification process. Instead of relying on physical government documents that can be copied and forged, the system creates a unique hash value that represents the verification result. This digital copy cannot be altered or counterfeited, as any change to the original data would result in a different hash value, thus eliminating the counterfeiting problem while maintaining ease of verification.
Solution Approach 2:
The patent replaces the mechanical/document-based verification system with a cryptographic system. Instead of using physical ID documents that can be tampered with, the system uses mathematical hash functions and cryptographic algorithms to create verification records. This substitution eliminates the vulnerability to physical counterfeiting while maintaining the ability to verify identities efficiently.
2Device complexity
If centralized government systems are used for identity verification, then verification authority is centralized, but the system becomes vulnerable to single point of failure and requires government support
Solution Approach 1:
The patent segments the centralized verification authority into distributed cryptographic verification points. Instead of relying on a single government system, the verification process is divided into multiple independent cryptographic operations that can be performed by different entities. Each verification record is independently hashed and verified, eliminating the single point of failure while maintaining verification authority through cryptographic consensus rather than centralized control.
Solution Approach 2:
The patent introduces cryptographic hash functions as intermediaries between the verification authority and the verification process. The hash function acts as a mathematical mediator that ensures data integrity and enables verification without requiring direct trust in a centralized authority. This intermediary layer provides security and reliability while allowing decentralized verification.
3Reliability
If user-generated items are used to create digital associations, then verification becomes more secure against forgery, but the process becomes more complex
Solution Approach 1:
The patent changes the parameters of the verification process by using cryptographic hash functions that operate on fixed-length input data. Instead of complex multi-step verification processes, the system uses standardized hash algorithms (such as SHA-256) that transform user-generated items into fixed-length hash values. This parameter change simplifies the verification process while maintaining high security, as the complexity is shifted from the verification algorithm to the cryptographic mathematics itself.
