Graphical Device Pairing via Encoded Visual Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication techniques between computing devices often require wired connections, complex configuration changes, and additional security measures, making the process time-consuming and cumbersome for users, thereby reducing user friendliness.
Innovation Solution
Graphically encoding a first device's address and secret to generate images that can be captured by a second device, allowing secure communication initiation only if the second device verifies knowledge of the secret, ensuring secure and effortless device pairing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wired connections and complex configuration changes are used for device communication, then security and reliability are improved, but ease of operation deteriorates
Solution Approach 1:
The patent replaces wired mechanical connections with wireless communication protocols, eliminating the need for physical plugging and configuration. Devices communicate wirelessly through encoded data transmission, maintaining security while dramatically improving ease of operation.
Solution Approach 2:
The patent uses graphical encoding to create visual copies of device addresses and secrets that can be captured by cameras. This allows secure data transfer through image capture and decoding, replacing complex manual configuration processes while maintaining communication security.
2Reliability
If additional security measures are implemented for secure communication, then communication security is improved, but device complexity deteriorates
Solution Approach 1:
The patent merges the address and secret into a single graphical code that contains all necessary authentication information. This consolidation eliminates the need for separate security configurations and manual entry of multiple parameters, reducing device complexity while maintaining security.
Solution Approach 2:
The system automatically generates, encodes, and verifies security credentials through the graphical data exchange process. Users simply capture the image with their camera, and the system handles all security verification automatically, eliminating complex manual security configurations.
3Reliability
If manual configuration steps are required for device pairing, then communication security is improved, but loss of time deteriorates
Solution Approach 1:
The patent pre-encodes the device address and secret into a graphical format before the pairing process begins. This preliminary preparation allows the receiving device to instantly capture and process all necessary authentication data in a single image, dramatically reducing pairing time while maintaining secure verification.

AI summary
In a computing device, both an address of a first device and a secret are graphically encoded to generate one or more images that can be captured by a second device. The second device captures and decodes the one or more images, and sends a communication initiation request to the address of the first device. The communication initiation request includes the address of the second device and identifies the secret. Communication between the first and second device continues only if the first device verifies, based on the communication initiation request, that the second device knows the secret.
