Figure-Based Authentication for Wireless Device Connection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Electronic devices face challenges in securely establishing wireless connections with other devices, requiring a method to authenticate and restrict unauthorized connections.
Innovation Solution
The solution involves generating and displaying a figure on one electronic device for authentication, transmitting this figure to another device, and establishing a connection based on the similarity between the input figure from the second device, allowing secure and easy connection establishment.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a connection authentication process is implemented to restrict unauthorized connections, then connection security is improved, but the complexity of the connection process increases
Solution Approach 1:
The patent uses a figure (visual pattern) as a copy or representation of the authentication credential instead of complex cryptographic keys or passwords. The first electronic device generates and displays a figure, and the second electronic device captures and transmits this figure back for verification. This simplifies the authentication process while maintaining security.
Solution Approach 2:
The patent introduces a figure as an intermediary element between the two electronic devices for authentication purposes. Instead of direct device-to-device credential verification, the figure serves as a mediator that carries authentication information in a simplified visual form that can be easily generated, transmitted, and verified.
2Reliability
If a traditional authentication method is used, then connection security is maintained, but the ease of establishing connection deteriorates
Solution Approach 1:
The patent replaces traditional mechanical or manual authentication methods (such as typing passwords or entering PINs) with a visual figure-based system. The first device generates and displays a figure, and the second device captures this figure using its camera or display and transmits it back. This substitution makes the authentication process more intuitive and easier to perform while maintaining security through figure verification.
3Reliability
If connection authentication is required, then unauthorized connections are restricted, but the time required for connection establishment increases
Solution Approach 1:
The first electronic device generates and displays the authentication figure in advance before the actual connection is established. This preliminary action allows the second device to capture and transmit the figure immediately when connection is requested, reducing the overall authentication time. The figure is prepared beforehand, so no complex real-time computation or verification is needed during the connection process.

AI summary
Various embodiments of the present invention relate to a device and method for providing connection between an electronic device and other electronic devices through figure input. According to one embodiment, a first electronic device comprises a display, a processor operatively connected to the display, and a memory operatively connected to the processor, wherein the memory may include instructions by which, when executed, the processor: generates a first figure for connection authentication of a second electronic device; displays the first figure through the display; transmits a signal related to the first figure to the first electronic device; when a response signal corresponding to the signal related to the first figure is received, identifies a second figure included in the response signal; determines whether the second electronic device is authenticated, on the basis of a similarity between the first figure and the second figure; and establishes connection to the second electronic device on the basis of a result of the determining.
