QR Control Code Provisioning for Secure IoT Device Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Internet of Things (IoT) devices face security challenges due to their network connectivity, which can lead to network attacks, and existing protection systems are difficult or costly to implement.
Innovation Solution
The use of Quick Response (QR) codes, specifically QR Control Codes (QRCCs), to provision and control Video Capable Devices (VCDs) securely by transferring commands through a QR image, minimizing security issues and enabling secure, faster, and more reliable communication without the need for a network interface.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If IOT devices are connected to network for manageability, then device control and monitoring are enabled, but security vulnerabilities and network attacks increase
Solution Approach 1:
The patent introduces QR codes as an intermediary medium for device provisioning and management. Instead of direct network connectivity, the system uses QR code images as a trusted intermediary that carries device identification and provisioning information. The camera captures the QR code, and the processing unit extracts information from it, creating a secure indirect communication path that eliminates network exposure during initial device setup and management operations.
2Reliability
If protection systems are implemented for network security, then device security is improved, but system complexity and cost increase
Solution Approach 1:
The patent extracts the security-critical provisioning and management functions from the network layer and relocates them to a local trusted execution path. By using QR code-based provisioning, the system removes the need for complex network security infrastructure (firewalls, authentication servers, encrypted channels) during device setup. The security function is extracted and implemented through simple local processes: camera capture, QR code decoding, and local database operations.
3Adaptability or versatility
If network interface is used for device communication, then remote management is enabled, but security risks and costs increase
Solution Approach 1:
The patent uses visual copying of information through QR codes as an alternative to electronic network communication. The device provisioning information is copied into a visual format (QR code image) that can be captured by a camera. This copying mechanism enables remote management capabilities without requiring network interfaces, as the information can be transmitted physically through visual means and then processed locally by the target device.

AI summary
In embodiments, apparatuses, methods, and storage media may be described for identifying a quick response (QR) image. A QR control code (QRCC) may be identified in the QR image based on a QR tag in the image. Based on the QRCC, a control command of an apparatus may be identified. Other embodiments may be described and/or claimed.
