Digital Voice Assistant Hierarchical Access Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Digital voice assistants lack secure access controls, allowing unauthorized users to perform tasks, such as placing online orders, due to the lack of hierarchical access levels and voice authentication.
Innovation Solution
A method and system that generate hierarchical access levels for digital voice assistants, creating a unique voice directive from user voice commands, and assigning access levels based on user identification, enabling secure rendering of services.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If voice command interface is enabled for digital tasks, then ease of operation is improved, but security and unauthorized usage risks worsen
Solution Approach 1:
The patent segments access rights by creating multiple hierarchical access levels (first access level, second access level, etc.) for different digital tasks. Each voice command is evaluated against the user's specific access level, allowing easy voice operation while maintaining security through segmented permission control.
Solution Approach 2:
The patent introduces voice biometric authentication as an intermediary layer between the user and digital tasks. The system captures voice characteristics, generates voiceprints, and verifies identity before granting access, serving as a mediator that enables convenient voice operation while ensuring secure authentication.
2Reliability
If hierarchical access levels are implemented, then security is improved, but device complexity worsens
Solution Approach 1:
The patent implements a universal voice authentication system that handles multiple access levels and task types through a single integrated framework. The voice biometric verification mechanism serves all access level checks, and the hierarchical structure provides a unified method for controlling diverse digital tasks, reducing overall system complexity despite multiple access levels.

AI summary
Method and system for providing secured access to services rendered by digital voice assistants are disclosed. In an example, the method includes generating, by the digital voice assistant in a set-up mode, hierarchical access levels for a plurality of services rendered by the digital voice assistant, based on an input from a super user. The method further includes generating, by the digital voice assistant in an operational mode and upon receiving a voice command from a user for a first time, a unique voice directive corresponding to the voice command. The unique voice directive comprises language tags and voice tags extracted from the voice command. The method further includes assigning an access level from among the hierarchical access levels to the unique voice directive and rendering a service from among the plurality of services based on the access level and the voice directive.
