Blockchain Personal Profiles for Cross-Platform User Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing online personal profiles are managed centrally by individual platforms, preventing the sharing of transaction history and user interactions across different platforms, which hinders consistent user authentication and interaction experiences.
Innovation Solution
A blockchain-based framework that establishes platform-independent personal profiles, using a service provider server to generate unique tokens linked to user profiles, incorporating identification and biometric data, and enabling universal authentication across various platforms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If personal profiles are managed centrally by individual platforms, then each platform can maintain control over user data, but user profiles cannot be shared across different platforms
Solution Approach 1:
The patent introduces a blockchain as an intermediary layer between users and individual platforms. The blockchain maintains a decentralized, shared ledger of user profiles and transaction histories, allowing platforms to access verified user data without centralized control. This mediator enables cross-platform profile sharing while preserving data security and user autonomy.
Solution Approach 2:
The patent creates a universal personal profile system that serves multiple platforms simultaneously. The blockchain-based profile acts as a multi-functional identifier that can be recognized and verified by different platforms, enabling a single profile to fulfill multiple functions across diverse service providers without requiring separate platform-specific profiles.
2Loss of information
If users establish separate personal profiles with each platform, then each platform can customize its own authentication system, but transaction history does not carry over between platforms
Solution Approach 1:
The patent ensures continuity of useful action by maintaining an uninterrupted, persistent record of user transaction histories on the blockchain. Once a transaction is recorded, it remains permanently accessible to authorized platforms, eliminating data loss between interactions and ensuring that user history continues to be recognized across different service providers.
Solution Approach 2:
The system implements feedback mechanisms where platforms can verify user identities and transaction histories through the blockchain, receiving confirmed data about user behavior and history. This feedback loop allows platforms to make informed decisions about user trust and authentication based on verified historical data, improving both security and ease of operation.
3Reliability
If centralized platforms manage user profiles, then authentication can be simplified for each platform, but trust and security are reduced due to lack of shared verification
Solution Approach 1:
The patent merges the verification functions of multiple platforms into a single unified blockchain system. Instead of each platform maintaining separate verification databases, all platforms share a common verification mechanism that checks against the decentralized blockchain ledger, combining trust and security functions across the ecosystem while reducing individual platform complexity.
Data Source
AI summary
Methods and systems are presented for using blockchain technologies to establish and manage personal profiles for users. A credential system registers a user by generating a token associated with a blockchain for the user, and storing authentication data associated with the user in the blockchain. The authentication data may include encoded data that represents an identification document and biometric data. After registering the user with the credential system, a verifier device can authenticate the user via the credential system using the authentication data stored on the user device. Additional information, such as interaction data associated with the user's interaction with various computer system can be added to the blockchain using the token generated for the user. The interaction data of the user with various computer systems, collectively, forms a universal personal profile of the user, and can be used by the various computer systems to manage the user.
