Voice Controlled Device Authentication via Multi-Sensor Presence Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice-controlled devices face issues with unintentional activation and lack of security, as they can recognize voice commands from users not present or unauthorized individuals, leading to frustration and potential safety risks, especially in environments with multiple users.
Innovation Solution
Implementing a multi-sensor system that determines the presence of a live human user before executing voice commands, using a combination of sensors such as motion, temperature, and video verification to ensure authentication and authorization, thereby preventing unintentional control and unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice control is implemented without additional authentication mechanisms, then ease of operation is improved, but reliability deteriorates due to unintentional activation and unauthorized access
Solution Approach 1:
The patent combines multiple authentication mechanisms (voice recognition, motion detection, temperature sensing, video verification) into a unified authentication system. This merging allows the system to maintain ease of voice-based operation while improving reliability through multi-factor verification, resolving the contradiction between operational simplicity and authentication accuracy.
Solution Approach 2:
The system performs preliminary authentication checks using motion sensors, temperature sensors, and video verification before processing voice commands. This preliminary action ensures that only authenticated users can activate voice control, preventing unintentional activation and unauthorized access while maintaining the ease of voice-based operation for authenticated users.
2Reliability
If multiple sensor types are integrated for authentication, then reliability is improved, but device complexity increases
Solution Approach 1:
The patent implements a universal authentication platform that can work with multiple sensor types (voice, motion, temperature, video) but only activates the sensors necessary for each specific authentication scenario. This multi-functionality approach allows the system to achieve high reliability through diverse authentication methods while managing device complexity by selectively activating only the required sensors.
Solution Approach 2:
The system implements a tiered authentication approach where not all sensor types are activated simultaneously or for all commands. Instead, the system applies partial authentication (using only necessary sensors) for low-risk operations and excessive authentication (using all available sensors) for high-risk operations, balancing reliability improvements with complexity management.

AI summary
Methods, systems, and devices are described herein. One method can include receiving a voice command from a user at a voice controlled device, determining a presence of the user to the device using a sensor, converting the voice command to a device specific command, and performing the device specific command using the device in response to the determined presence.
