Interactive Whiteboard Projector Secure Data Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for distributing meeting content from interactive whiteboard projectors are insecure, cumbersome, and require IT configuration, especially when dealing with large attachments, security concerns, and varying participant access rights.
Innovation Solution
An interactive whiteboard projector generates a password and displays a URL, allowing meeting participants to securely download meeting data using a web browser, with optional QR code access and time-expiration password for enhanced security and convenience.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If meeting content is distributed via email, then participants can access meeting data, but security risks increase and large attachments are rejected
Solution Approach 1:
The patent uses a web server as an intermediary between the projector and participants. The projector uploads content to the web server, which then serves the content through a browser-based interface. This intermediary approach avoids direct email transmission limitations and security issues, allowing secure access without attachment size restrictions.
Solution Approach 2:
The patent replaces the mechanical email system with a web-based retrieval system. Instead of using email servers and attachments, the system uses HTTP/HTTPS protocols and web browsers to transfer content. This substitution eliminates the harmful factors of email server capacity limits and encryption requirements while maintaining security through authenticated access.
2Reliability
If USB keys are used for content distribution, then participants can save meeting content, but the process becomes slow and cumbersome
Solution Approach 1:
The patent replaces the physical USB key mechanism with a web-based digital access system. Instead of requiring physical insertion and copying, participants access content through a web browser using credentials. This eliminates the slow copying process while maintaining security through authenticated access and automatic content delivery.
3Reliability
If enterprise file servers are used for content storage, then meeting content can be saved, but IT configuration requirements increase
Solution Approach 1:
The patent implements a self-service system where the projector automatically handles content upload and participant access without requiring IT staff configuration. The system uses built-in projector functionality to create web pages, manage authentication, and serve content. This eliminates the need for complex IT configuration while maintaining enterprise-grade security through authenticated access control.
4Ease of operation
If email is used for content distribution, then participants receive meeting data, but users cannot selectively access specific content
Solution Approach 1:
The patent segments meeting content into distinct files and categories on the web server. Participants can access specific content types (presentations, notes, videos) through organized web pages. This segmentation allows selective access to relevant content while maintaining a structured, manageable system that doesn't overwhelm users with all meeting data at once.
Data Source
AI summary
Distributing meeting data from an interactive whiteboard projector to at least one computer of a meeting member, comprises: in the interactive whiteboard projector, using a processor to save meeting data, generate a password, display a screen with a URL of the projector and the password and use a web server to transfer the meeting data from the interactive whiteboard projector to the at least one computer.
