Guest Assistant Personalization Without Full Sign-In
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing automated assistants often require multiple user interactions and authentication steps to operate in a signed-in mode, which is impractical for transient user interactions, limiting functionality and raising security concerns on non-persistent devices.
Innovation Solution
Implementing a transient personalization mode that allows guest users to access personalized responses using data from their associated automated assistant devices, leveraging biometric authentication and encrypted communication to facilitate seamless interaction without full authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple authentication interactions are required for signed-in mode, then data security is improved, but ease of operation deteriorates for transient users
Solution Approach 1:
The patent segments the authentication process into two distinct modes: guest mode for transient users with limited functionality, and signed-in mode for persistent users with full access. This segmentation allows the system to apply different authentication requirements based on user type, resolving the contradiction by providing strong security for signed-in mode while maintaining ease of operation for guest mode through simplified access.
Solution Approach 2:
The patent applies partial authentication for guest users, providing a subset of signed-in functionality without requiring full authentication credentials. This partial action approach allows transient users to access basic automated assistant features without undergoing multiple authentication interactions, thus improving ease of operation while maintaining adequate security through the guest mode restrictions.
2Reliability
If multiple authentication interactions are required, then data security is improved, but loss of time increases
Solution Approach 1:
The patent segments user access into guest mode and signed-in mode, allowing transient users to immediately access the automated assistant in guest mode without undergoing time-consuming authentication procedures. This segmentation eliminates authentication delays for transient users while maintaining data security through the restricted functionality of guest mode.
Solution Approach 2:
The system performs preliminary setup by configuring the automated assistant to support both guest and signed-in modes from initialization. This preliminary action ensures that when transient users arrive, they can immediately access guest mode without requiring real-time authentication setup, thereby eliminating authentication delays while maintaining security through pre-configured access controls.
3Measurement precision
If signed-in mode is enforced, then speech processing accuracy is improved, but device complexity increases
Solution Approach 1:
The patent segments the operational modes into guest mode and signed-in mode, where speech processing accuracy enhancements are selectively applied only to signed-in users. This segmentation allows the system to maintain high speech processing accuracy for authenticated users while avoiding the complexity of implementing these enhancements for all users, thus resolving the contradiction between accuracy and device complexity.
Solution Approach 2:
The patent applies local quality by providing enhanced speech processing capabilities specifically to signed-in users based on their authentication status. The system adjusts speech recognition language selection, term biasing, and response rendering quality locally for authenticated users, rather than uniformly across all users. This localized application of quality enhancements improves speech processing accuracy where needed while minimizing the overall device complexity burden.

AI summary
Implementations set forth herein relate to an automated assistant that can operate in a transient personalization mode, and/or assist a separate automated assistant with providing output according to a transient personalization mode. The transient personalization mode can allow a guest user of an assistant enabled-device to receive personalized responses from the assistant-enabled device-despite not being signed into the assistant-enabled device. A host automated assistant of the assistant-enabled device can securely communicate with a guest user's automated assistant through a backend process. In this way, input queries from the guest user to the host automated assistant can be personalized according to the guest automated assistant-without the guest user directly engaging with their own personal device.
