Single Logout System for Cross-Device Session Management
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing client-server communication systems lack efficient mechanisms for automatically closing, locking, or logging out applications across devices when user-interface inactivity is detected, leading to potential unauthorized access and resource management issues.
Innovation Solution
Implementing a system that uses client devices to monitor user-interface activity through counters or timestamps, sending periodic messages to servers to determine inactivity periods, and automatically closing, locking, or logging out applications after specified intervals, while allowing single-login logout functionality across multiple applications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If applications remain open across multiple devices without centralized logout control, then user convenience is improved, but security and resource management deteriorate due to potential unauthorized access
Solution Approach 1:
The patent implements a universal logout mechanism that works across multiple applications and devices through a single logout request. The system maintains a registry of applications and devices, allowing a centralized logout function to terminate sessions across the entire ecosystem rather than requiring separate logout actions for each application or device, thus maintaining security while preserving user convenience
2Ease of operation
If applications remain open across multiple devices, then user convenience is improved, but resource consumption increases due to inactive sessions
Solution Approach 1:
The system implements feedback mechanisms where the server monitors application activity across devices and automatically terminates sessions based on inactivity detection. The server receives status information from client devices about application usage and sends logout requests when inactivity thresholds are exceeded, thereby automatically managing resource consumption without requiring user intervention while maintaining convenience during active usage
3Loss of energy
If single logout functionality is implemented across multiple applications, then resource management is improved, but system complexity increases
Solution Approach 1:
The patent introduces an intermediary component (such as a gateway or session management service) that mediates between client devices and multiple applications. This intermediary maintains a registry of active sessions and coordinates logout requests across applications, thereby simplifying the overall system architecture compared to implementing complex peer-to-peer session management between all components while still achieving efficient resource management through centralized control
Data Source
AI summary
A system includes an activity manager connected with a device, an application server and an identity provider. The activity manager clears a device session with both the identity provider and the application server to logout applications provided by the application server to the device.
