Solution Overview

Problem

Existing screen sharing technologies over P2P networks face security risks due to unintended data sharing and are inconvenient, requiring prior user and IP address registration.

Innovation Solution

A user terminal system that issues an authentication number for secure screen sharing, allowing direct P2P connection, authenticating the number, and limiting data transmission rates for multiple connections, while enhancing user-friendliness and security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If P2P network is used for screen sharing, then network configuration becomes simpler and connection speed improves, but security risks increase due to unintended data sharing

Engineering Contradiction:

Improvenetwork configurationVSAvoidsecurity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent introduces an authentication number as an intermediary mechanism between the P2P connection endpoints. This authentication number acts as a mediator that verifies the legitimacy of connection requests, allowing the system to maintain simple P2P networking while adding a layer of security verification that prevents unauthorized connections

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If user and IP address registration is required beforehand, then security is improved, but system complexity and ease of operation deteriorate

Engineering Contradiction:

ImprovesecurityVSAvoidconfiguration complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The patent implements preliminary action by pre-generating and storing authentication numbers on both the transmission and reception terminals before actual screen sharing begins. This preliminary preparation eliminates the need for complex real-time registration processes, allowing users to simply input the pre-prepared authentication number for quick connection establishment

Inventive Principle:

Principle #10Preliminary action

3Adaptability or versatility

If multiple destination terminals are connected, then versatility improves, but data transmission rate and quality deteriorate

Engineering Contradiction:

Improvenumber of connected terminalsVSAvoiddata transmission rate

Core Design Contradiction:

Adaptability or versatilityVSProductivity

Solution Approach 1:

The patent applies dynamics by making the data transmission rate adjustable based on the number of connected destination terminals. The system dynamically adapts the transmission parameters according to the current connection load, allowing it to maintain optimal performance across varying numbers of connected devices rather than being fixed at a single transmission rate

Inventive Principle:

Principle #15Dynamics

AI summary

A user terminal 10 for screen sharing with a destination user terminal 100 receives a connection request for screen sharing from a user; issues an authentication number to specify the destination user terminal 100 with which the user terminal 10 is to perform screen sharing, in response to the connection request; directly connects with the destination user terminal 100; allows the destination user terminal 100 to display a prompt to ask for an input of the authentication number; authenticates the authentication number in response to receiving the authentication number from the destination user terminal 100; and sequentially transceives shared screen data to and from the destination user terminal 100 if the authentication number is appropriate.
