Tracing Pattern Device Pairing Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing device pairing methods lack a secure and user-friendly solution for multi-device authentication, particularly in scenarios where a single user needs to manage multiple devices simultaneously, such as enlarging display size, without increasing user actions.
Innovation Solution
A method and device implementation that generates a tracing pattern on both devices, allowing a user to authenticate pairing by tracing the pattern on one or both screens, with feedback information confirming the correct device, utilizing wireless communication and considering display characteristics for alignment and security validation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional pairing methods (PIN code, passphrase, NFC, touch) are used, then device pairing can be authenticated, but the user actions required increase and security may be compromised in multi-device scenarios
Solution Approach 1:
The patent combines the display screens of multiple devices to form a single unified interface for pairing authentication. Instead of requiring separate authentication actions on each device, the tracing pattern is distributed across multiple screens, allowing the user to complete the authentication gesture across the combined display area, thereby reducing the number of discrete user actions while maintaining security
Solution Approach 2:
The patent extends the pairing authentication from a two-dimensional single-screen gesture to a multi-dimensional experience across multiple device screens. The tracing pattern spans across device boundaries, utilizing the spatial arrangement of multiple displays to create a larger authentication canvas, which reduces the complexity of user actions while enhancing security through pattern recognition across devices
2Adaptability or versatility
If a single user manages multiple devices simultaneously (e.g., for enlarging display), then new usages are enabled, but existing pairing interfaces become inadequate
Solution Approach 1:
The patent creates a universal pairing interface that functions across multiple devices simultaneously. The tracing pattern authentication mechanism is designed to work regardless of which device is displaying which portion of the pattern, making the pairing process adaptable to various multi-device configurations and use cases, thereby enabling versatile multi-device management without increasing interface complexity
Solution Approach 2:
The patent segments the tracing pattern across multiple device screens, with each device displaying a portion of the overall pattern. This segmentation allows the pairing interface to accommodate multiple devices while maintaining a unified authentication experience, as the user traces the complete pattern across the segmented displays without perceiving the division between devices

AI summary
It is provided a method for pairing two devices, one of which is a first device the other is a second device, wherein the method is implemented at the first device, including: generating a pattern to be displayed on either of or both of the first and second devices; sending whole or a part of the tracing pattern to the second device for displaying the tracing pattern on the second device if any; displaying the corresponding pattern on the first device; receiving information indicating the result of tracing the pattern on the second device; and accepting pairing the two devices.
