Interactive Whiteboard Session Termination via Occupancy Detection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Interactive whiteboards face security breaches due to unattended writing, which can lead to inadvertent disclosure of sensitive information, as existing systems lack effective automatic session-ending mechanisms to ensure data protection.
Innovation Solution
An interactive whiteboard system equipped with sensors that detect user presence and activity, automatically syncing data to a remote server and deleting local storage when the user is no longer nearby, ensuring secure logout and data protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If occupancy sensors are used to detect user presence and automatically control whiteboard sessions, then data security is improved, but device complexity increases
Solution Approach 1:
The whiteboard system automatically detects user presence through occupancy sensors, syncs data to remote servers, and ends sessions without requiring manual user intervention. The system serves itself by monitoring its own state and taking appropriate actions, thereby improving data security while the automation handles the complexity internally.
Solution Approach 2:
A remote server acts as an intermediary between the whiteboard system and data storage. The whiteboard syncs data to the server rather than storing it locally, providing an additional layer of security. The server mediates the data storage function, allowing the whiteboard to maintain security without managing complex local storage systems.
2Reliability
If automatic session ending is implemented, then data protection is improved, but ease of operation deteriorates
Solution Approach 1:
The system automatically monitors user presence and manages session ending without requiring users to remember to log out. Occupancy sensors continuously check for user presence, and the system autonomously syncs data and ends sessions when users leave, protecting data while adding no operational burden to users.
Solution Approach 2:
The system uses occupancy sensor feedback to automatically trigger data synchronization and session ending. When sensors detect user absence, the system receives feedback and automatically executes protective actions, creating a closed-loop system that protects data without requiring user awareness or intervention.
3Reliability
If data synchronization to remote server is performed, then data security is improved, but use of energy increases
Solution Approach 1:
The system performs data synchronization periodically based on occupancy detection rather than continuously. When occupancy sensors detect user presence, the system knows data needs to be synced. When users are absent, the system pauses synchronization, reducing energy consumption while maintaining security through periodic updates.
Solution Approach 2:
The system automatically determines when data synchronization is needed based on its own operational state and user presence detection. It self-regulates the synchronization process to minimize energy consumption while ensuring data is backed up when necessary, without requiring external control or continuous operation.
Applied Scientific Principles
This section explains which scientific principles are used to turn an abstract innovation direction into a practical engineering solution.
Function Achieved in This Case
The system effectively prevents data breaches by ensuring secure logout and data synchronization, maintaining data integrity and security even when users forget to log out, thereby protecting sensitive information.
Implementation Method 1
Typical sensors use passive infrared (PIR) technology. These detect infrared energy from moving objects.
