Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current identity and data verification systems are cumbersome, time-consuming, error-prone, and expose entities and individuals to fraud and identity theft, with inefficient management of large volumes of data.
Innovation Solution
A decentralized verification method using blockchain infrastructure, where each participant is associated with a unique decentralized identifier (DID), enabling secure storage and sharing of personal information while allowing verification through a trusted entity, and utilizing identity authority (IA) tokens and DIDs to authenticate entities.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional centralized verification systems are used to verify identity and data, then verification can be performed with established authority, but the process becomes cumbersome, time-consuming, and error-prone
Solution Approach 1:
The system performs preliminary verification actions by pre-establishing trust relationships through decentralized identifiers (DIDs) and verifiable credentials. Identity verification data is prepared and stored in advance on the holder's device, eliminating the need for time-consuming manual verification processes during actual transactions.
Solution Approach 2:
The patent introduces a blockchain-based intermediary layer that mediates between verifying parties and verified parties. This intermediary enables automated verification through cryptographic proofs and smart contracts, replacing manual verification processes and significantly reducing verification time while maintaining reliability.
2Reliability
If traditional centralized systems collect and manage large volumes of personal data, then verification can be performed, but entities spend significant time and resources to verify, store, and manage the data
Solution Approach 1:
The system extracts only the essential verification data needed for identity confirmation and stores it locally on the holder's device in the form of verifiable credentials. This eliminates the need for centralized storage and management of large volumes of personal data, significantly improving data management efficiency while maintaining verification reliability.
Solution Approach 2:
The holder's device automatically manages verification data locally, performing self-verification without requiring external entities to store or process the data. The device itself verifies its own identity credentials through cryptographic proofs, eliminating the resource-intensive data management processes in traditional centralized systems.
3Reliability
If manual data collection processes are used, then entities can gather necessary information, but the process exposes entities to fraud and individuals to identity theft
Solution Approach 1:
The patent replaces manual mechanical data collection processes with automated cryptographic verification mechanisms. Identity verification is performed through cryptographic proofs and digital signatures rather than manual data collection, eliminating vulnerabilities to fraud and identity theft while ensuring data integrity through mathematical guarantees.
Solution Approach 2:
The system applies preliminary anti-action by pre-establishing cryptographic security measures and trust frameworks before any data exchange occurs. Verifiable credentials are issued with built-in security controls and verification mechanisms that prevent fraud and identity theft from the outset, rather than attempting to detect or respond to these threats after they occur.

AI summary
Methods of determining whether to trust an entity before sharing information with the entity, as well as methods of verifying whether to trust information received from an entity, are disclosed. In the processes, two entities, referred to as a holder and a verifier, desire to engage in an exchange of digital information. Before the holder will share information with the verifier, the holder will determine whether the verifier is a trusted entity. Before the verifier trusts information that it receives from the holder, it will examine a proof that it received from the holder to determine whether the proof includes information from or about a trusted third party referred to as an issuer. Information from an identity authority may be used in each of these verification steps.
