Encrypted Wireless Authentication for Motion Alarm Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional motion detection and alarm systems frequently trigger unnecessary alarms due to the movement of authorized entities such as pets, members, or vehicles, leading to undesirable and repetitive alerts.
Innovation Solution
A system comprising a monitoring system with detectors, beacons, and electronic devices that utilize encrypted wireless signals for authentication, allowing authorized entities to deactivate alarms through a self-authentication process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If conventional motion detection systems trigger an alarm for any detected movement, then security monitoring is maintained, but unnecessary alarms are frequently triggered by authorized entities such as pets, members, or vehicles
Solution Approach 1:
The patent introduces an intermediary authentication system between motion detection and alarm triggering. When motion is detected, the system first checks for the presence of authorized entities through electronic device authentication (e.g., mobile devices, key fobs) before activating the alarm. This intermediary step filters out authorized movements from triggering false alarms while maintaining security for unauthorized movements.
Solution Approach 2:
The system enables authorized entities to self-authenticate using their own electronic devices. The authentication process is automated and does not require manual intervention from security personnel. The system automatically recognizes authorized devices, verifies their credentials, and suppresses alarm triggers accordingly, allowing the system to serve itself in distinguishing authorized from unauthorized movements.
2Object-generated harmful factors
If motion detection systems differentiate between authorized and unauthorized entities, then unnecessary alarms are reduced, but system complexity increases due to authentication requirements
Solution Approach 1:
The patent leverages universally owned electronic devices (smartphones, tablets, key fobs) as authentication credentials. Instead of requiring specialized access control hardware for each authorized entity, the system uses multi-functional devices that people already carry daily. This universal approach reduces the need for additional specialized equipment while maintaining robust authentication capabilities.
Solution Approach 2:
The system replaces traditional mechanical or electronic access control systems (such as key cards, biometric scanners, or physical keys) with wireless communication-based authentication. The authentication process uses wireless signals between the monitoring system and electronic devices, eliminating the need for physical interaction with access control hardware and reducing mechanical complexity.
3Reliability
If electronic devices are required for authentication, then authorized movement can be recognized, but loss or theft of electronic devices may compromise security
Solution Approach 1:
The system performs preliminary authentication checks before allowing authorized movement. Electronic devices must be verified and authenticated in advance before they can suppress alarm triggers. The system maintains a pre-configured list of authorized devices and their credentials, performing verification before critical security decisions are made, ensuring that even if a device is lost, unauthorized use is prevented without preliminary authentication.
Solution Approach 2:
The authentication system continuously monitors and verifies electronic device credentials in real-time. When motion is detected, the system immediately checks the current authentication status of the associated electronic device. If the device has been reported lost or stolen, the system receives feedback about its compromised status and accordingly triggers alarms even for authorized entities, dynamically adjusting security responses based on real-time authentication feedback.
Data Source
AI summary
A system for authorizing movement of an entity in a zone is described. The system includes a monitoring system and an electronic device associated with an entity. The monitoring system is configured to detect the movement of the entity within the zone and transmit a first encrypted wireless signal. The electronic device is configured to receive the first encrypted wireless signal, decrypt the first encrypted wireless signal, generate a second encrypted wireless signal based on the decryption, and transmit the second encrypted wireless signal to the monitoring system. The monitoring system is configured to receive the second encrypted wireless signal and authenticate the electronic device based on the received second encrypted wireless signal. The monitoring system is configured to authorize the detected movement of the entity upon the authentication of the electronic device and deactivate an alarm or a response device based on the authorization.
