Communication Adapter Image-Based Wireless LAN Setup
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Users face complex and time-consuming settings when configuring wireless LAN communication between devices and adapters, requiring security measures like passwords to prevent unauthorized access, which complicates the process and may lead to interception.
Innovation Solution
A communication device with an input unit, mode setting unit, character string generation unit, image generation unit, encryption processing unit, and communication processing unit that generates a random character string, converts it into machine-unrecognizable image data, and uses it for secure encryption and decryption, simplifying the setting process while ensuring security.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the communication path is protected using a password to ensure security, then security is improved, but the setting work becomes complicated and time-consuming
Solution Approach 1:
The patent introduces an image as an intermediary carrier that conveys connection information (SSID and password) from the communication device to the terminal. Instead of directly transmitting sensitive text data or requiring manual password input, the system embeds connection credentials within an image that can be easily shared and processed, thus maintaining security while simplifying the setting process
Solution Approach 2:
The patent replaces the manual password input mechanism with an automated image-based authentication system. The terminal automatically extracts connection information from the received image without requiring the user to manually type passwords, substituting a mechanical input process with an automated optical recognition process
2Ease of operation
If the communication path is not protected using a password to save user labor, then ease of operation is improved, but unauthorized access or interception of communication may occur
Solution Approach 1:
The patent performs preliminary encryption of connection information before transmitting it to the terminal. The communication device encrypts the SSID and password data and embeds it within an image structure before transmission, so that even if the image is intercepted, the connection credentials remain protected. This preliminary security measure allows the system to maintain both ease of operation and security
3Reliability
If dedicated remote controller is used for configuring wireless LAN setting, then security is improved, but adaptability is worsened
Solution Approach 1:
The patent makes the communication device itself perform the function of a remote controller by enabling it to generate and transmit configuration images directly to terminals. This eliminates the need for a separate dedicated remote controller and allows any terminal with image processing capability to configure wireless LAN settings, thus achieving universality while maintaining security through the image-based authentication mechanism

AI summary
A communication adapter includes: an input unit receiving an operation for requesting transition to a setting mode; a mode setting unit setting a communication mode to the setting mode when the input unit receives the operation for requesting transition to the setting mode; a character string generation unit generating a random character string when receiving a connection start request from a terminal in the setting mode; an image generation unit converting the random character string into image data indicating an image that is difficult for a machine to recognize; an encryption processing unit encrypting transmission data to be transmitted to the terminal using the random character string as an encryption key, and decrypting reception data received from the terminal using the random character string; and a communication processing unit transmitting the image data and the encrypted transmission data to the terminal, and receiving the reception data from the terminal.
