User Presence Notifications With Trusted Wake and Lock Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional UPD-capable information handling systems face issues in multi-user environments, including spurious system wake events and unauthorized access due to lack of customization in wake and lock methods, leading to power loss and security vulnerabilities.
Innovation Solution
Implementing a database of trusted users (TMU database) with biometric data to manage user presence, allowing secure wake and lock operations based on user identity and trust status, reducing spurious events and unauthorized access.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Speed
If user presence detection is implemented without trusted user database, then system wake responsiveness is improved, but security and power management deteriorate due to spurious wake events and unauthorized access
Solution Approach 1:
The system applies different quality levels of user verification to different wake scenarios. Trusted users stored in the TMU database receive immediate wake response with full system access, while untrusted users trigger a delayed wake response with security verification requirements. This local differentiation of response quality based on user trust status resolves the contradiction by maintaining fast response for legitimate users while preventing spurious wakes and unauthorized access from untrusted users.
2Reliability
If customized wake and lock methods are implemented with trusted user database, then security is improved, but device complexity increases
Solution Approach 1:
The TMU database serves multiple functions simultaneously: it stores biometric data for user identification, maintains trust status for security decisions, and enables both wake and lock operations under unified security policies. By making the trusted user database universal across different security operations (wake, lock, access control), the system achieves enhanced security without proportionally increasing complexity, as a single database structure supports multiple security-critical functions.
3Reliability
If biometric data verification is performed for all user presence events, then unauthorized access is prevented, but processing time and energy consumption increase
Solution Approach 1:
The system performs biometric verification partially - only for untrusted users attempting to wake or access the system. Trusted users stored in the TMU database bypass verification and receive immediate access. This partial application of verification action resolves the contradiction by applying security checks only where necessary (for untrusted users) while avoiding unnecessary processing time and energy consumption for trusted users, thus maintaining security without excessive overhead.

AI summary
Systems and methods are provided for collecting, distributing and managing notifications of user presence. More specifically, systems and methods are provided for collecting notifications of user presence that are generated by a first IHS and distributing the notifications of user presence to a second IHS for notification, aggregation and/or analysis of user presence events. In some embodiments, notifications of user presence may be collected from the first IHS and distributed to the second IHS to provide notification of user presence events to the second IHS (or a user of the second IHS). In other embodiments, the notifications of user presence generated by the first IHS may be aggregated and/or analyzed by the second IHS to generate various metrics for the user presence events that occur at the first IHS. In doing so, the disclosed embodiments enable security (and other policies) to be set in a data-based, empirically driven way.
