Electronic Door Voice Passthrough for Remote Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing door systems lack efficient and secure methods for controlling access through voice recognition, particularly in terms of data processing and authentication, which can lead to security vulnerabilities and inefficiencies.
Innovation Solution
A door system that integrates a controller to collect audio input via a microphone, transmit it to an external device for processing, and facilitate multi-factor authentication using a remote database, reducing the controller's size and enhancing security by offloading data processing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If voice recognition processing is performed locally in the door controller, then authentication speed is improved, but the controller size and complexity increase
Solution Approach 1:
The patent extracts the voice recognition processing function from the door controller and relocates it to a remote server. The controller only collects audio data and transmits it to the server for processing, thereby reducing local complexity while maintaining fast authentication through distributed processing architecture.
Solution Approach 2:
The patent introduces a remote server as an intermediary between the door controller and the authentication database. The server handles complex voice recognition and database comparison operations, allowing the controller to remain simple while achieving fast authentication through the intermediary's processing capabilities.
2Device complexity
If voice recognition processing is performed remotely, then controller size is reduced, but authentication response time increases
Solution Approach 1:
The patent implements preliminary action by pre-storing voice profiles and authentication criteria in the remote database before actual authentication occurs. When authentication is needed, the system only needs to transmit audio data and compare it against pre-existing profiles, significantly reducing processing time despite the remote location.
Solution Approach 2:
The patent replaces the mechanical limitation of local processing power with network-based distributed processing. By substituting local computational requirements with remote server capabilities, the system achieves small controller size while maintaining acceptable response times through efficient data transmission and processing architecture.
3Reliability
If local processing is used for voice authentication, then system reliability is improved, but security against data breaches decreases
Solution Approach 1:
The patent extracts sensitive authentication data and processing logic from the local controller to a remote server. This extraction ensures that even if the controller is compromised, the authentication database and processing algorithms remain secure on the remote server, significantly improving security against data breaches.
Solution Approach 2:
The patent uses a remote server as an intermediary that protects authentication data through centralized security measures. The server acts as a secure intermediary between the controller and the authentication database, providing encryption and access controls that enhance overall system security while maintaining reliable authentication.
Data Source
AI summary
A door system includes a controller. The controller is configured to receive an indication of a trigger event associated with a door, initiate a collection of data via an audio device, provide a prompt for a user to provide an audio input, terminate the collection of data based on criteria associated with the audio input or the trigger event, and transmit the data to an external device for processing by the external device.
