Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional identity cards and documents with anti-counterfeiting measures are used, then identity verification can be performed, but they are increasingly subject to successful reproduction by modern techniques leading to fraud
Solution Approach 1:
The patent introduces a blockchain-based identity verification system as an intermediary between identity providers and verification systems. This mediator uses distributed ledger technology to store and verify identity information, replacing the direct verification of physical documents that is vulnerable to counterfeiting. The blockchain acts as a trusted third party that eliminates the need for complex anti-counterfeiting measures while providing robust security through cryptographic verification.
Solution Approach 2:
The patent replaces mechanical/physical identity verification methods (examining physical cards, documents, holograms, and anti-counterfeiting features) with a digital/blockchain-based verification system. Instead of manually inspecting physical artifacts, the system uses cryptographic proofs and distributed ledger verification to authenticate identities, eliminating the vulnerability to physical counterfeiting techniques.
2Adaptability or versatility
If multiple identities from different identity providers are maintained, then access to various services and systems is enabled, but it creates a highly differentiated identity environment resulting in inefficiencies for both individuals and third parties
Solution Approach 1:
The patent implements a universal identity verification system where a single blockchain-based identity can be used across multiple services and systems. The system allows identity information to be issued by various identity providers but verified through a common blockchain platform, enabling one identity to serve multiple functions and access different services without requiring separate identity management for each provider.
Solution Approach 2:
The patent combines multiple identity verification systems into a unified blockchain-based platform. Instead of maintaining separate verification processes for each identity provider, the system merges them into a single distributed ledger that can verify identities from any provider, simplifying the overall identity management ecosystem while maintaining access to diverse services.
3Ease of operation
If traditional identity verification processes are used, then access authorization can be provided, but it presents a danger of fraud as developing technologies prove increasingly effective at counterfeiting identities
Solution Approach 1:
The patent replaces complex manual verification processes that require examining physical documents and anti-counterfeiting features with automated blockchain-based verification. The system maintains operational simplicity by using straightforward digital verification steps while dramatically improving reliability through cryptographic security and distributed ledger immutability, eliminating the trade-off between simplicity and security.

AI summary
An identity system is disclosed comprising: an identity creation module to generate an identity token, the generated identity token incorporating an identifier representing identity data of an identity generated for an individual by an identity provider, the incorporated identifier being stored in a data structure associated with program instructions of a smart contract of a distributed ledger system, the data structure and the program instructions of the smart contract being stored in a distributed ledger of the distributed ledger system; a first interface to a user system of the individual to provide the generated identity token to the user system; a second interface to a restricted access system to receive a token received by the restricted access system from the user system or data extracted from the token; an identity verification module to invoke an identity verification function of the program instructions of the smart contract to determine whether at least a portion of the extracted data matches the identifier stored in the data structure of the smart contract in the distributed ledger of the distributed ledger system; and wherein the second interface outputs to the restricted access system an indication of a validity of the identity generated by the identify provider based on the determination.
