Agent Device Privacy Control for Multi-User Voice Assistance
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing voice assistant services lack privacy protection for multiple users, particularly in environments like vehicles where personal information of one user may be inadvertently shared with others.
Innovation Solution
A program that estimates the number of users based on their positions, determines the availability of personal information in a storage unit, and adjusts output information accordingly to protect privacy by limiting access to personal data when multiple users are present.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If access privileges are set to multiple users in a voice assistant service, then the service can be used by multiple users, but personal information of one user may be inadvertently shared with other users
Solution Approach 1:
The patent segments user information into personal information and non-personal information, and further divides access control by estimating the number of users. The system determines whether to provide personal information based on the estimated user count, thereby segmenting the information access rights for different user scenarios.
Solution Approach 2:
The patent dynamically adjusts information access policies based on the estimated number of users. The determination unit changes its behavior according to the estimated user count, switching between providing personal information and withholding it, making the access control mechanism dynamic rather than static.
2Ease of operation
If personal information is always made available to users, then the service provides convenient assistance, but privacy protection is compromised when multiple users are present
Solution Approach 1:
The patent changes the parameter of information availability based on the estimated number of users. The determination unit adjusts whether personal information is available by changing this parameter according to the user count estimation, thereby balancing convenience and privacy protection.
3Productivity
If the system always provides personal information, then user assistance is optimized, but information security is compromised in multi-user environments
Solution Approach 1:
The estimation unit continuously estimates the number of users based on user information, and the determination unit uses this feedback to adjust information availability. This feedback mechanism allows the system to adapt its information security policies based on real-time user conditions.

AI summary
Non-transitory computer-readable recording medium stores program for agent device. Program, when executed by computer constituting agent device, causes computer to execute: input step to receive instruction information from user by voice or touch operation and user information regarding user; recording step to record information including personal information regarding user in storage unit; estimation step to estimate current number of user based on user information; determination step to determine whether personal information stored in storage unit is available based on whether current number of user is singular or plural; determination step to determine output information corresponding to instruction information using information stored in storage unit based on determination result whether personal information is available; and output step to output voice and/or image as output information.
