Wireless Projecting Control System with Protocol-Level Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current conference reporting systems face data security risks due to the need for specific software installation on computers, which can lead to unauthorized data extraction if hacked, and lack flexibility in managing different authority levels for data transmission.
Innovation Solution
A wireless projecting control method and system that sets operation restrictions, allowing selective and restricted image signal projection to a display device, with the transmitter or receiver executing these restrictions to enhance data security through various authority levels, using a communication device to manage data transmission modes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If specific software is installed in computers for wireless communication, then data transmission capability is improved, but data security deteriorates due to potential hacking and unauthorized extraction
Solution Approach 1:
The patent extracts the software dependency from the computer system by implementing wireless projection functionality directly in the projector through hardware-based protocols. This removes the vulnerable software component from the transmission chain while maintaining data transmission capability, thereby resolving the security vulnerability associated with installed software.
Solution Approach 2:
The patent introduces an intermediary authentication mechanism that operates at the protocol level rather than through application software. This intermediary layer verifies device identities and establishes secure connections without requiring software installation on the computer, thus maintaining transmission capability while improving security.
2Reliability
If operation restrictions are implemented for security, then data security is improved, but operational flexibility deteriorates
Solution Approach 1:
The patent implements dynamic authority level settings that can be adjusted during operation. Different users or devices can be assigned different authority levels (e.g., view-only, edit, admin) allowing the system to adapt security restrictions based on operational needs, thus maintaining both security and flexibility.
Solution Approach 2:
The patent applies different security restrictions to different functions or data types based on authority levels. Rather than uniform restrictions, each operation can have tailored security requirements, allowing flexible control where high security is applied only where necessary while maintaining ease of operation for permitted actions.
3Adaptability or versatility
If key data is generated in computer software for authorized sharing, then sharing functionality is improved, but vulnerability to hacking increases
Solution Approach 1:
The patent replaces the software-based key generation mechanism with a hardware-based authentication system. Authority levels and sharing permissions are managed through protocol-level authentication rather than software-generated keys, eliminating the vulnerability to software hacking while preserving authorized sharing functionality.
Solution Approach 2:
The patent introduces an intermediary authentication protocol that mediates between the computer and projector without requiring key generation in computer software. This intermediary layer handles authorization securely at the communication protocol level, reducing the attack surface while maintaining sharing capabilities.

AI summary
A wireless projecting control method includes setting at least one operation restriction, communicating a transmitter with a receiver or a communication device for executing at least one restricted operation by the transmitter or the receiver, and selectively or restrictedly projecting an image signal to a display device by the receiver after the transmitter or the receiver executes the at least one restricted operation. The image signal is generated by the communication device. The transmitter is used for transmitting the image signal to the receiver according to the at least one operation restriction.
