Conference Data Sharing With Dynamic Access Authorization
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing conference reporting systems face risks of information leakage due to wireless data transmission and lack flexibility in adjusting authorized actions, necessitating a high-security, high-convenience data sharing method.
Innovation Solution
A conference data sharing system and method involving a transmitter, receiver, and display device, where the receiver generates data signals based on a member list and transmits them through a network, while the transmitter processes image signals for display, using authorization keys to control access and adjust sharing permissions dynamically.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If wireless communication is used for transmitting conference data, then operational efficiency and convenience are improved, but the risk of information leakage increases
Solution Approach 1:
The patent segments the data transmission process into multiple controlled stages: authorization key generation, selective data signal transmission to authorized members only, and controlled image signal transmission. This segmentation allows wireless communication to be used efficiently while maintaining security through granular control over what data is transmitted to whom.
Solution Approach 2:
The patent introduces an intermediary authorization mechanism where authorization keys are generated and distributed through the wireless network to control access. This intermediary layer (the authorization key system) mediates between the wireless transmission capability and security requirements, allowing efficient wireless communication while preventing unauthorized access through cryptographic control.
2Ease of operation
If specific software is installed in computers for data transmission, then data can be transmitted through wireless network, but device complexity and installation requirements increase
Solution Approach 1:
The patent implements a universal transmitter device that can work with multiple types of image signal sources (computers, tablets, mobile phones, projectors) without requiring specific software installation on each device. The transmitter serves multiple functions: detecting various image signal sources, generating authorization keys, and controlling wireless transmission, thereby simplifying the system while maintaining ease of operation across different devices.
Solution Approach 2:
The transmitter automatically detects image signal sources and generates authorization keys without requiring manual software installation or configuration on participating devices. The system performs self-service functions including automatic device detection, automatic authorization key generation, and automatic transmission control, eliminating the need for complex software installation procedures.
3Reliability
If computers are linked to transmitters through wired connection, then data transmission is stable, but operational convenience and flexibility are reduced
Solution Approach 1:
The patent replaces the mechanical wired connection system with a wireless communication system. The transmitter wirelessly transmits both authorization keys and image signals to authorized members' devices, eliminating the need for physical cable connections while maintaining transmission reliability through cryptographic authorization and controlled wireless protocols.
Data Source
AI summary
A conference data sharing method includes triggering a transmitter coupled to an image signal source, transmitting a triggering signal from the transmitter to a receiver through a first network, generating at least one data signal according to a conference member list after the receiver receives the triggering signal, transmitting the at least one data signal to at least one conference member through a second network, transmitting an image signal from the image signal source to the transmitter after the transmitter is triggered, processing the image signal by the transmitter for transmitting the image signal to the receiver through the first network, and controlling a display device for displaying an image by the receiver according to the image signal.
