Virtual Passport Identity Verification via Blockchain
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional identity verification systems are vulnerable to hacking and require each entity to manage and store identity information individually, lacking a secure and efficient method for entities to verify identities without duplicating efforts and ensuring data integrity.
Innovation Solution
An open architecture identity verification system using a virtual passport, where a public/private key pair is generated, the virtual passport is signed with the private key, and stored on a public blockchain, allowing entities to verify identities securely and efficiently by retrieving the signed virtual passport from the blockchain.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If each entity manages and stores identity information individually, then entities can verify identities independently, but security is vulnerable to hacking and data integrity cannot be ensured
Solution Approach 1:
The patent merges identity verification functionality into a standardized passport document that can be universally accepted across multiple entities. The passport combines identity information, cryptographic signatures, and verification mechanisms into a single integrated structure, eliminating the need for each entity to maintain separate identity databases and verification systems.
Solution Approach 2:
The patent introduces a trusted authority as an intermediary that issues and signs passports. This mediator creates a chain of trust where the authority's digital signature on the passport serves as verification of identity, allowing entities to trust passport authenticity without directly verifying identity information themselves.
2Productivity
If entities duplicate verification efforts individually, then each entity can verify identities independently, but efficiency is reduced due to redundant work
Solution Approach 1:
The patent implements preliminary action by having a trusted authority pre-verify identities and issue passports before individuals approach service entities. The verification work is performed in advance during passport issuance, so when entities need to verify identities, they only need to check the passport's cryptographic signature rather than重新 performing full identity verification.
Solution Approach 2:
The patent creates a verified copy of identity information in the form of a passport document. Instead of entities accessing and verifying original identity data multiple times, they verify copies (passports) that have been authenticated by a trusted authority, eliminating redundant verification efforts across different entities.
3Ease of operation
If identity information is stored centrally, then verification is simplified, but the system becomes vulnerable to single points of failure and hacking
Solution Approach 1:
The patent extracts the verification mechanism from centralized identity databases and embeds it directly into the passport document itself through cryptographic signatures. The critical verification capability is taken out of the centralized system and placed in the distributed passport documents, so that even if a central authority is compromised, the verified identity information remains secure in the signed passports.
Solution Approach 2:
The trusted authority performs preliminary verification and embedding of cryptographic signatures during passport issuance. This preliminary action creates self-contained verified identity documents that do not require continuous connection to or validation against central databases, reducing the attack surface of centralized systems while maintaining verification simplicity.
Data Source
AI summary
A method includes verifying the identity of an individual. A virtual passport for the individual is created upon verifying the identity of the individual. The virtual passport uniquely identifies the individual. A public/private key pair associated with the individual is generated. The virtual passport is signed with the private key. The signed virtual passport is entered in a public block chain. The signed virtual passport may be retrieved from the public block chain. The authenticity of the signed virtual passport may be determined via the public key.
