Biometric Profile Activation on Shared Devices
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional methods for user profile selection and activation on shared devices lack identification and authentication, leading to unauthorized access and settings changes without verification.
Innovation Solution
A computer-implemented method and system that determines the association between a user device and a shared user profile, uses biometric verification to authenticate the user, and activates the specific user profile on a multiuser device when the user is within a predetermined proximity, employing modules for proximity detection and authentication.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional methods of user profile selection are used on shared devices, then ease of operation is improved, but security and reliability deteriorate due to lack of identification and authentication
Solution Approach 1:
The patent replaces conventional mechanical or manual authentication methods (such as physical keypads, buttons, or simple passcodes) with biometric verification systems. This substitution enables secure identification of users on shared devices while maintaining ease of operation, as biometric verification (fingerprint, facial recognition, etc.) is more convenient and secure than traditional methods.
2Reliability
If biometric verification is implemented for user profile selection, then security and reliability are improved, but device complexity increases
Solution Approach 1:
The patent implements a universal authentication framework where a single biometric verification system can authenticate multiple users and manage multiple user profiles on shared devices. This multi-functional approach consolidates what would otherwise require separate authentication mechanisms for each user, thereby reducing overall system complexity while maintaining high security standards.
3Reliability
If user identification and authentication are required, then security is improved, but ease of operation deteriorates due to additional verification steps
Solution Approach 1:
The patent enables self-service authentication where users automatically verify their identity through biometric verification without requiring manual intervention or complex verification steps. The system autonomously identifies the user, retrieves the appropriate user profile, and activates it, making the process as easy as presenting the device for verification while maintaining strict access control.

AI summary
Disclosed are systems and methods for secure selection of a user profile in a shared context. For example, a method may include: determining, by one or more processors, an association between a user device and a shared user profile; determining, by the one or more processors, that the user device is within a predetermined proximity of a multiuser device; determining, by the one or more processors, the shared user profile associated with the user device as a result of determining that the user device is within the predetermined proximity of the multiuser device; receiving, by the one or more processors, biometric verification from the first user; and activating, by the one or more processors, the first specific user profile associated with the first user on the multiuser device as a result of determining that the first user has successfully provided biometric verification.
