Swipe-Based Device Pairing via Temporal Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for establishing relationships between terminal devices, such as smartphones, require burdensome processes like database searches and user input, making them inefficient for generating relationship information.
Innovation Solution
A server or terminal device system that determines whether the interval between swipe operations on touch panels of different devices falls within a prescribed range, generating relationship information based on this determination, thereby simplifying the process and reducing user input.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional server-mediated processes are used for generating relationship information, then authentication can be established, but the processing burden and user input requirements increase significantly
Solution Approach 1:
The patent extracts the essential authentication verification from the complex server-mediated process. Instead of requiring full server processing including database searches, invitation sending, and service joining prompts, the system extracts only the critical element: verifying temporal correlation between swipe operations. This simplification maintains authentication reliability while dramatically reducing processing burden.
Solution Approach 2:
The terminal devices perform self-authentication by locally detecting and timestamping swipe operations, then independently determining whether the temporal relationship between swipes meets authentication criteria. This self-service approach eliminates the need for heavy server-mediated processing while maintaining secure relationship establishment.
2Reliability
If multiple server-mediated processes are required, then authentication can be established, but the time required for relationship information generation increases
Solution Approach 1:
The system performs preliminary timestamping of swipe operations as they occur on each terminal device. By recording the exact timing of each swipe locally and immediately, the system prepares authentication data in advance, eliminating the need for time-consuming server-mediated verification processes later. This preliminary action significantly reduces the time required for relationship information generation while maintaining authentication reliability.
3Productivity
If users must input various information types, then relationship information can be generated, but the ease of operation decreases
Solution Approach 1:
The terminal devices automatically capture swipe operation data including timestamps and operation details without requiring any manual information input from users. The system self-generates all necessary authentication data through automatic detection of user swipe gestures, eliminating the burden of manual information entry while maintaining productive relationship information generation.
4Reliability
If database searches and invitation processes are required, then authentication can be established, but the device complexity increases
Solution Approach 1:
The patent extracts only the essential temporal verification component from the complex authentication process. Instead of implementing full database searches, invitation sending, and service joining workflows, the system extracts merely the critical function of verifying whether the time interval between swipe operations falls within a prescribed range. This extraction maintains authentication reliability while dramatically simplifying the processing steps required.

AI summary
To provide a server device with which the burden of processing can be reduced during generation of relationship information among multiple terminal devices. The server device can include a communication unit for communicating with a first terminal device having a first touch panel, and with a second terminal device having a second touch panel; and a controller for determining whether an interval of time that is identified on the basis of first operation information received from the first terminal device via the communication unit and corresponding to a first swipe operation performed on the first touch panel, and second operation information received from the second terminal device via the communication unit and corresponding to a second swipe operation performed on the second touch panel, falls within a prescribed range, and for generating prescribed relationship information on the basis of the result of the determination.
