Passport-Based User Registration and Login for Privacy Isolation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing user identity systems lack autonomy, with centralized organizations controlling user data and privacy, leading to violations and no effective solutions for accessing applications using autonomous identities.
Innovation Solution
A user registration and login method utilizing passports and user cards, issued by management and application websites, that verify user identities through public keys and signatures, allowing users to derive multiple accounts while isolating privacy and securing identity information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If centralized organizations allocate user identities and control user data, then user identity management is simplified and centralized, but user privacy is violated and user autonomy is lost
Solution Approach 1:
The system segments identity management into multiple independent components: users generate their own keys locally, passports are issued by application websites independently, and verification is distributed across different platforms. This segmentation eliminates the need for a centralized identity authority while maintaining systematic identity management.
Solution Approach 2:
The patent introduces cryptographic intermediaries (public-private key pairs, digital signatures, and passport structures) that mediate between users and application websites. These cryptographic intermediaries enable trusted identity verification without requiring centralized organizational control over user data.
2Ease of operation
If users register with traditional centralized systems, then account creation is straightforward, but users must memorize accounts and passwords and cannot control their own data
Solution Approach 1:
Users perform self-service by generating their own key pairs locally on their devices. The system automatically handles key generation, passport creation, and verification processes without requiring users to memorize passwords or manually manage credentials. Users maintain full control over their identity data while enjoying simplified registration.
Solution Approach 2:
The passport structure serves multiple functions: it acts as an identity credential, a verification token, and a portable identity record that can be used across different application websites. This universal passport system replaces multiple platform-specific accounts and passwords with a single versatile identity solution.
3Productivity
If centralized organizations obtain and use user identity data for commercial purposes, then organizational revenue is generated, but user privacy is seriously violated
Solution Approach 1:
The patent extracts the commercial value generation function from centralized identity control. Application websites can independently verify user identities and provide services without needing to collect, store, or commercialize user personal data. The verification process extracts only the necessary authentication information through cryptographic proof, leaving user privacy intact.
Solution Approach 2:
The system uses cryptographic copies (digital signatures and passport structures) instead of original personal data. Application websites verify user identities by checking cryptographic copies rather than accessing actual user information. This copying mechanism enables service delivery and commercial operations without exposing or misusing user privacy data.

AI summary
The present disclosure relates to the technical field of Internet, and provides a user registration method, a user login method and a device corresponding thereto. In these methods, a passport or the user card records identity information of the autonomous identity of a user, and the user can use the passport or the user card to access an application website, which is unlike the conventional method of performing the accessing through the account and the password. Moreover, the present disclosure further implements a series of mechanisms from the application to the use, concerning the passport and the user card.
