Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The increasing number of IoT devices in home and other environments poses challenges in managing network security, as users are vulnerable to intrusion and data theft, requiring a secure platform for controlling and authenticating IoT devices to ensure privacy and security.
Innovation Solution
A security device with a blockchain node manages IoT devices, establishing trusted communications and providing secure access through biometric authentication, acting as a mediator between IoT devices and external services, and operating as a pseudo certificate authority to ensure secure transactions and resource allocation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If users directly connect IoT devices to external services, then device functionality is accessible, but network security and vulnerability to intrusion increase
Solution Approach 1:
The patent introduces a security device as an intermediary component between IoT devices and external services. This security device manages communications, establishes trusted connections, and controls access to external services, thereby maintaining device accessibility while enhancing network security through centralized security management and authentication mechanisms.
2Adaptability or versatility
If multiple IoT devices are deployed in IoT environment, then functionality and data collection increase, but risk of data theft and intrusion increases
Solution Approach 1:
The security device acts as a mediator that manages all communications between multiple IoT devices and external services. It implements authentication, authorization, and secure communication protocols, allowing diverse IoT devices to maintain their functionality while protecting against data theft through centralized security control.
Solution Approach 2:
The system implements feedback mechanisms where the security device continuously monitors communications, validates device identities, and adjusts security parameters based on detected threats or anomalies. This enables the system to respond dynamically to security risks while maintaining device operational capabilities.
3Ease of manufacture
If traditional security management is used for IoT devices, then implementation is simple, but security control and trust management are insufficient
Solution Approach 1:
The security device serves as a dedicated intermediary component that centralizes security management functions. This approach maintains implementation simplicity by providing a single security management point while significantly enhancing security control capabilities through specialized security protocols, authentication mechanisms, and trusted connection management.
Data Source
AI summary
Techniques are described for managing a network through use of a security device that includes, or has access to, a blockchain node. The security device may manage a network of Internet-of-Things (IoT) devices in a home or other environment. The security device may act as an intermediary to manage secure, trusted communications between the IoT device(s) and external service(s). The security device may also provide network security features such as a network firewall. In some implementations, the security device may run a blockchain node, and the blockchain could be used to establish a verifiable home identity. The security device may interact with external resources and/or services, such as utility services, e-commerce services, and so forth, through this secure mechanism.
