Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing security systems for homes and commercial properties face challenges with low power consumption and secure communication, particularly in scenarios where internet connectivity is disrupted, making them vulnerable to intrusions and data loss.
Innovation Solution
A low power device system with a server-based handshake key exchange for secure communication sessions, using cipher block chaining and session nonces encrypted with a handshake key, allowing secure communication between a mobile device and the low power device without the mobile device possessing the handshake key.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If existing security systems use cabling and continuous network streaming for video transmission, then video capture and transmission capability is improved, but system vulnerability to disruption during intrusions increases and network load increases
Solution Approach 1:
The system performs preliminary actions by capturing and storing video data locally in the security box before any potential disruption occurs. The security box maintains a local storage capability that ensures video data is preserved even when network connectivity is interrupted during an intrusion event, eliminating the need for continuous network streaming.
Solution Approach 2:
The security box acts as an intermediary between the cameras and the network. It receives video data from cameras, processes and stores it locally, and then transmits it to remote devices when network connectivity is available. This intermediary role allows the system to function reliably during intrusions without requiring continuous network connection.
2Ease of operation
If existing security systems require continuous internet access for remote viewing and alarm notification, then remote accessibility is improved, but system downtime during internet disruption increases
Solution Approach 1:
The system performs preliminary actions by storing video data and alarm information locally in the security box before any disruption occurs. This local storage ensures that when internet connectivity is restored, the system can immediately transmit the captured data and notifications without requiring continuous connection, maintaining reliability during internet disruptions.
Solution Approach 2:
The security box provides self-service functionality by maintaining local storage and processing capabilities that allow it to operate independently of continuous internet access. It can capture, store, and manage security data locally, and only requires network connectivity for optional remote viewing and notification transmission.
3Adaptability or versatility
If existing security systems use multiple cameras with continuous streaming, then security coverage is improved, but network load and power consumption increase
Solution Approach 1:
The system extracts the video processing and storage function from the network infrastructure and places it in the security box. This extraction allows multiple cameras to capture video simultaneously without requiring continuous network streaming, as the security box handles local processing and storage, significantly reducing network load and power consumption.
Solution Approach 2:
Instead of continuous streaming, the system uses periodic action by transmitting data only when needed or when connectivity is available. The security box stores data locally and performs periodic or event-driven transmissions to remote devices, reducing continuous power consumption and network load while maintaining comprehensive security coverage.

AI summary
A server is in communication with a low power device. The server has a handshake key (Kh) with a key exchange that provides for a communication session between a mobile device and the low power device. The mobile device does not have the (Kh). A user mobile device is in communication with the server and uses a cipher to provide a secured communication between the mobile device and the low power device.
