Intermediation Device for Multi-Service Account Linking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing technologies require users to manage multiple service accounts separately for each service provider, leading to complex authentication processes and increased development efforts for linking services, as the OAuth protocol only supports one-to-one links, complicating the registration and usage of multiple services.
Innovation Solution
An intermediation method and system that allows for the registration and execution of linking permissions between multiple application services using a central intermediation device, which authenticates accounts and stores linking permission information, enabling seamless access across services without requiring separate APIs for each pair of services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the OAuth protocol is used for service linking, then secure access between services is achieved, but the system complexity increases dramatically when multiple services are involved
Solution Approach 1:
The patent introduces a linking service as an intermediary component that manages authentication between multiple services. Instead of implementing direct OAuth links between every pair of services (which creates exponential complexity), the linking service acts as a central mediator that handles authentication requests, reducing the system from a many-to-many complex relationship to a simplified many-to-one relationship where all services communicate through the single linking service
2Reliability
If direct OAuth linking is implemented between each service pair, then secure authentication is achieved, but the development effort and API requirements increase exponentially
Solution Approach 1:
The linking service is designed as a universal component that can handle authentication for any combination of services through a single standardized interface. Instead of developing custom APIs for each service pair, the linking service provides multi-functional capability to manage authentication across all services, reducing development effort from exponential to linear scaling
3Reliability
If multiple service accounts are managed separately, then service security is maintained, but user operation complexity increases
Solution Approach 1:
The patent merges multiple service accounts under a single linking service interface. Instead of requiring users to manually manage and authenticate with separate accounts for each service, the system combines access to multiple services through one unified account structure managed by the linking service, maintaining security while dramatically simplifying user operations

AI summary
An intermediation method used in an intermediation system that includes an intermediation device determining a permission for application services requiring user authentication on a network, where in response to a user request, a first account used for a first service and a second account used for a second service, and a registration request for using the linking service linking the first application service and the second application service are associated with each other, when the two accounts are valid, as accounts usable in a linking service, an association between the first and second services is stored in the intermediation device, and when the user makes a request to use the linked services, that use is controlled by a query to the intermediation device regarding whether the account is associated as able to use the linking service.
