Server-Mediated Device Linking via Matching Symbols
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for linking devices, especially for authentication purposes, are inconvenient due to the need for local connections or manual data transfer, which can be error-prone and require compatible interfaces, limiting their applicability and user experience.
Innovation Solution
A method where a server selects and sends matching linking information to both devices, allowing users to recognize and confirm the match without the need for local connections or manual data entry, using recognizable and potentially graphical information to associate device characteristics securely and conveniently.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If local connections or manual data transfer are used for device linking, then security can be maintained, but ease of operation deteriorates due to error-prone manual entry and interface compatibility requirements
Solution Approach 1:
The patent introduces a server as an intermediary that automatically generates and distributes linking information to both devices. This mediator eliminates the need for manual data transfer between devices while maintaining security through server-controlled verification. The server acts as a trusted third party that coordinates the linking process, resolving the contradiction between security and ease of operation.
Solution Approach 2:
The patent uses graphical linking information that is copied and displayed on both devices simultaneously. Instead of manual data entry, the same visual information appears on both device screens, allowing users to verify matching graphical representations. This copying approach maintains security through verification while dramatically improving ease of operation by eliminating manual typing and interface compatibility concerns.
2Reliability
If manual data transfer methods are used, then device linking can be achieved, but productivity deteriorates due to time-consuming manual entry and verification processes
Solution Approach 1:
The server performs preliminary actions by pre-generating and distributing the linking information to both devices before the user needs to verify the match. This eliminates the need for users to manually create or transfer data during the linking moment. The graphical information is prepared in advance and simply needs to be visually compared, dramatically speeding up the process while maintaining accuracy.
3Reliability
If compatible interfaces and local connections are required for device linking, then data transfer can be performed, but adaptability deteriorates due to limitations on device compatibility
Solution Approach 1:
The patent creates a universal linking mechanism that works across different device types and communication capabilities. By using a server as the central coordination point that sends information to both devices independently, the system becomes adaptable to various device configurations. The linking method does not require specific interface compatibility between the two devices being linked, only their ability to display the graphical information and communicate with the server.
Data Source
AI summary
A method for linking of a first characteristic of a first device and a second characteristic of a second device by a server is disclosed. The method comprises the steps of selecting a first linking information and a second linking information, the first linking information matching to the second linking information, sending from the server the first linking information to the first device and the second linking information to the second device, presenting by the first device the first linking information and by the second device the second linking information, entering into the first device an indication of the matching of the first linking information and the second linking information, and based on the entered indication of the matching, sending to the server a matching confirmation for confirming the matching to the server, and associating the first characteristic and the second characteristic based on the received matching confirmation.
