Solution Overview

Problem

Remote control of high functionality mobile communication terminals poses a risk of personal information leakage due to the display of screen information during remote access sessions, particularly in sensitive sectors like finance and health, and existing solutions require complex user interactions that can lead to errors and software conflicts.

Innovation Solution

A method that blocks transmission of screen information by setting a sense area in the task bar of the mobile communication terminal's touch screen, allowing users to control screen information visibility with simple touches, eliminating the need for inputting commands or implementing separate icons, thereby preventing personal information leakage during remote control sessions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If remote control program is executed to enable remote access, then remote control capability is improved, but personal information leakage risk increases

Engineering Contradiction:

Improveremote control capabilityVSAvoidpersonal information leakage risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The screen information transmission is segmented into controllable segments. The system divides screen content into transmissible portions and non-transmissible portions, allowing selective blocking of sensitive information while maintaining remote control functionality for non-sensitive areas.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

A screen information blocking program acts as an intermediary between the remote control program and the screen display system. This intermediary layer receives screen information, determines which portions should be blocked based on sensitivity, and selectively transmits or blocks information before it reaches the display.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If complex handling procedures are implemented for blocking screen information, then information security is improved, but ease of operation deteriorates

Engineering Contradiction:

Improveinformation securityVSAvoiduser interaction complexity

Core Design Contradiction:

Object-affected harmful factorsVSEase of operation

Solution Approach 1:

The system automatically identifies and blocks sensitive screen information without requiring user intervention. The screen information blocking program autonomously analyzes screen content, determines sensitivity based on predefined criteria, and blocks appropriate portions automatically, eliminating the need for complex user handling procedures.

Inventive Principle:

Principle #25Self-service

Solution Approach 2:

The system performs preliminary classification and blocking of sensitive information before it is displayed or transmitted during remote control sessions. By pre-configuring blocking rules and automatically applying them, the system prepares security measures in advance rather than requiring reactive user actions during sensitive operations.

Inventive Principle:

Principle #10Preliminary action
