Smart Access Control via Biometric and Location Verification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing property monitoring systems lack efficient methods for controlling access to unattended properties by service providers, often relying on inadequate authentication processes and failing to ensure secure and timely rearming of security systems after service completion.
Innovation Solution
A monitoring system that employs a three-factor authentication process, including biometric identification, location verification, and scheduled access periods, to grant access to authorized service providers while ensuring the property is secured upon their departure, using sensors and a control unit to communicate with an external server and disarm/rearm the security system accordingly.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional authentication processes are used for service provider access, then ease of operation is maintained, but security and reliability of property access control deteriorates
Solution Approach 1:
The authentication process is segmented into three distinct factors: biometric authentication (fingerprint, facial recognition), location verification (GPS coordinates, geofencing), and scheduled access period validation. Each factor is verified separately by the monitor control unit before granting access, ensuring comprehensive security while maintaining a structured, manageable process flow.
Solution Approach 2:
The monitor control unit acts as an intermediary between the service provider's electronic device and the property access control system. It receives authentication data from the service provider's device, processes the three-factor verification, communicates with the access control mechanism, and manages the arming/disarming of the security system, thereby simplifying the overall process while enhancing security.
2Productivity
If access is granted to service providers during unattended periods, then productivity of service delivery is improved, but risk of unauthorized access or property damage increases
Solution Approach 1:
The system performs preliminary actions by pre-scheduling access periods for service providers and pre-configuring authentication requirements before the service provider arrives. The monitor control unit validates the scheduled access period against the current time and verifies authentication factors in advance, ensuring that access is granted only when all conditions are met, thereby preventing unauthorized access while enabling efficient service delivery during approved time windows.
Solution Approach 2:
The system continuously monitors the service provider's location via GPS coordinates and compares it against the property's geofenced boundaries. Real-time feedback is provided to the monitor control unit, which can immediately revoke access or trigger alerts if the service provider deviates from authorized areas or remains beyond the scheduled access period, thus mitigating risks while maintaining productivity.
3Ease of operation
If security system remains armed during service provider access, then safety is maintained, but ease of operation and service completion efficiency deteriorates
Solution Approach 1:
The security system's arming state is dynamically adjusted based on the service provider's authentication status and location. The monitor control unit automatically disarms the security system when the service provider is authenticated and enters the property, and automatically rearms it when the service provider exits or the scheduled access period ends. This dynamic adjustment ensures continuous security monitoring is maintained without manual intervention, balancing safety with operational efficiency.
4Productivity
If manual security system arming/rearming is required after service completion, then control precision is maintained, but loss of time and productivity deteriorates
Solution Approach 1:
The monitor control unit performs self-service by automatically detecting when the service provider has completed the service (through location verification and exit detection) and autonomously rearms the security system without requiring manual intervention from property owners or security personnel. This automation eliminates time loss associated with manual security operations while maintaining precise control over when the system is armed or disarmed.
Data Source
AI summary
A method includes, receiving a biometric identifier from a visitor to the property, determining an arrival time of the visitor based on receiving the biometric identifier, comparing the arrival time of the visitor to an expected arrival time of an expected visitor, based on comparing the arrival time of the visitor to an expected arrival time, transmitting the biometric identifier and data identifying the expected visitor, receiving, by the monitoring system and from the external server, (i) data indicating that the biometric identifier corresponds to the expected visitor and (ii) data indicating that an electronic device of the expected visitor is located at the property, and based on (i) the data indicating that the biometric identifier corresponds to the expected visitor and (ii) the data indicating that the electronic device of the expected visitor is located at the property, granting, by the monitoring system, the visitor access to the property.
