Infrared Authentication Signal for IoT Device Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for connecting and authenticating Internet of Things (IoT) devices, such as smart appliances, require direct user intervention, which is inconvenient and vulnerable to unauthorized access.
Innovation Solution
An electronic device method that identifies a registered IoT device through scanning, establishes a communication connection using identification information and a preset password, requests infrared codeset information, and transmits an authentication signal over infrared light to authenticate the device, minimizing user intervention.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mutual authentication based on certificates, PIN input, or QR code scan is used for device authentication, then security is improved, but user convenience deteriorates due to direct intervention being required
Solution Approach 1:
The system enables self-service authentication where the electronic device automatically performs device discovery, connection establishment, and authentication with the registered device without requiring user actions such as pressing buttons, inputting PINs, or scanning QR codes. The authentication process is autonomously completed through wireless communication protocols.
Solution Approach 2:
The patent introduces an intermediary authentication mechanism where the electronic device acts as a mediator between the user and the registered device. Instead of direct user-device interaction, the electronic device handles the authentication process by establishing wireless connections and exchanging authentication data, thereby eliminating the need for direct user intervention while maintaining security.
2Ease of operation
If SoftAP is activated for easy setup, then device connectivity is improved, but security deteriorates due to vulnerability to unauthorized access
Solution Approach 1:
The system applies preliminary anti-action by implementing authentication verification before allowing any device to connect to the SoftAP. The electronic device verifies the identity of connecting devices against a pre-registered device list, and only authorized devices are permitted to establish connections. This prevents unauthorized access while maintaining the ease of SoftAP-based setup.
Solution Approach 2:
The system implements feedback mechanisms where the electronic device continuously monitors connection requests to the SoftAP, verifies them against authentication criteria, and provides real-time feedback by accepting or rejecting connection attempts. This ensures that only authenticated devices can access the network while maintaining setup convenience.
