Blockchain One ID Service System for Cross-Platform Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face inconvenience and service providers experience burden in managing multiple IDs and passwords for different sites, with existing single ID login technologies requiring separate authentication servers that are difficult to manage effectively.
Innovation Solution
A blockchain-based ID service system where a specific service provider issues an ID for logging into multiple sites, registers it on a blockchain network, and handles authentication procedures, eliminating the need for a separate authentication server and allowing automatic ID generation and updates based on user information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a separate authentication server is used for one ID login service, then users can log in to multiple sites with one ID, but the authentication server becomes difficult to manage effectively
Solution Approach 1:
The patent extracts the authentication server from the system architecture and replaces it with blockchain-based smart contracts. The authentication logic is moved from a centralized server to distributed blockchain nodes, eliminating the management burden of maintaining a separate authentication server while preserving one ID login functionality across multiple sites.
Solution Approach 2:
The patent introduces an authentication supporting server that acts as an intermediary between users and service provider servers. This server manages ID registration and authentication coordination on the blockchain network, simplifying the overall system architecture by consolidating authentication management functions rather than requiring a dedicated authentication server for each site.
2Reliability
If users manage separate ID and password for each site, then security may be improved, but user convenience deteriorates due to time and effort required
Solution Approach 1:
The patent implements a universal ID system where a single ID issued by one service provider can be used to log in to multiple different sites. The blockchain network enables this ID to be recognized and validated across different service provider servers, eliminating the need for users to create separate accounts at each site while maintaining security through cryptographic verification.
Solution Approach 2:
The patent performs preliminary authentication by having users complete the membership subscription and ID issuance process at one trusted service provider site. Once the ID is registered on the blockchain, this preliminary authentication action is valid across all participating sites, saving users the time of repeating the membership process at each new site.
3Adaptability or versatility
If service providers hold and manage personal information of members, then user service can be provided, but burden and cost increase due to security management difficulty
Solution Approach 1:
The patent extracts personal information management from service provider servers and stores it on the blockchain network. User profiles and authentication data are held in smart contracts rather than centralized databases, reducing the burden on service providers while maintaining the ability to provide personalized services through blockchain-based identity verification.
Data Source
AI summary
Provided are a blockchain-based one ID service system and method, in an authentication method according to the embodiment of present invention, an authentication support server maps and registers a first ID issued by a first SP server to a first user and a first site of the first SP server, which is an issuing server, and, upon receiving the first ID from a second SP server, the authentication support server returns information on the first site mapped to the first ID to the second SP server. To this end, there is no need for a separate server configuration to perform an authentication procedure, and it is possible to lessen the burden of performing authentication for SPs.
