Voice-Activated Access Control via Backend Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing call box systems in apartment buildings require residents to manage multiple phone numbers and rely on traditional keypads for access, which can be cumbersome and insecure, especially for managing guest or delivery access.
Innovation Solution
A backend system that integrates with call boxes to use passphrases or access words, where residents can set and use audio tones or voice recognition to grant access, allowing secure and convenient entry through voice responses or barcode passphrases.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traditional keypad systems are used for access control, then the system is simple to implement, but it becomes cumbersome and insecure for managing guest or delivery access
Solution Approach 1:
The patent replaces traditional mechanical keypad input with voice-based authentication. The system captures voice inputs through a microphone, processes them through speech-to-text conversion, and validates passphrases verbally. This substitution eliminates the need for physical keypads and codes, providing more secure and convenient access control while reducing the complexity of managing multiple phone numbers and access codes.
2Adaptability or versatility
If multiple phone numbers are managed for different access scenarios, then access control flexibility is improved, but the ease of operation deteriorates
Solution Approach 1:
The patent creates a universal voice-based access control system that handles multiple access scenarios (guest access, delivery access, resident access) through a single interface. The system uses natural language processing to interpret different types of access requests and automatically routes them to the appropriate authentication method, eliminating the need for users to manage multiple phone numbers or switch between different access systems.
Solution Approach 2:
The system enables self-service access control where residents can independently manage their own access codes, guest permissions, and delivery instructions through voice commands. The automated speech recognition and natural language processing allow the system to understand and execute access requests without requiring manual configuration or intervention from building management, significantly improving ease of operation.

AI summary
Methods and devices for using a backend system to allow access to a residence are provided herein. In some embodiments, a call box located at a residence may call a telephone number associated with a user account on the backend system that corresponds to a resident of the residence. When the call box calls the telephone number associated with the user account, an audio message may be provided that includes a question whose answer is a user selected passphrase. A response to the question is then analyzed to determine whether or not the response includes the passphrase. If so, a signal, such as an audible tone, is provided to the call box. The audible tone, when played, may cause a door of the residence to become unlocked.
