Solution Overview

Problem

Existing electronic devices expose important information transmitted via messages, such as SMS, LMS, and MMS, to external view without adequate protection.

Innovation Solution

Implementing a method and apparatus that allows for generating and transmitting messages with hidden text areas using a touch pen, and controlling display to show only non-hidden text, with options for authentication and limited checks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If the entire message text is displayed on the screen, then the user can easily read and understand the message content, but sensitive information is exposed to external view without adequate protection

Engineering Contradiction:
Improvemessage readabilityVSAvoidinformation exposure
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The message text is divided into visible portions and hidden portions. The display screen is segmented into a message display area where only non-sensitive parts of the message are shown, while sensitive information is stored in a separate hidden area that requires authentication to access. This segmentation allows normal readability while protecting sensitive content from accidental exposure.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

An intermediary authentication mechanism is introduced between the hidden message area and the user. The processor acts as a mediator that controls access to sensitive information by requiring authentication (such as fingerprint, password, or pattern recognition). This intermediary layer prevents direct access to sensitive information while allowing authenticated users to view the complete message.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Object-affected harmful factors

If hidden areas are added to messages to protect sensitive information, then information security is improved, but the device complexity increases due to authentication mechanisms and hidden area management

Engineering Contradiction:
Improveinformation exposureVSAvoidauthentication system complexity
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The message display apparatus is designed to perform multiple functions: displaying visible message content, storing hidden sensitive information, and providing authentication services. The processor integrates these functions into a unified system that manages both visible and hidden areas, reducing the need for separate dedicated components and thereby limiting the increase in device complexity.

Inventive Principle:
Principle #6Universality (Multi-functionality)

Solution Approach 2:

The hidden message area is nested within the overall message structure, with the authentication mechanism nested within the message display system. The sensitive information is embedded within the message data, and the authentication layer is integrated within the display control logic. This nested structure allows the system to maintain a compact architecture while providing multiple layers of protection and functionality.

Inventive Principle:
Principle #7Nested doll (Nesting)

3Object-affected harmful factors

If authentication and check limits are implemented, then message privacy and security are enhanced, but the ease of operation is reduced due to additional user steps required

Engineering Contradiction:
Improveinformation exposureVSAvoiduser access convenience
Core Design Contradiction:
Object-affected harmful factorsVSEase of operation

Solution Approach 1:

Authentication credentials (such as fingerprints, passwords, or recognition patterns) are pre-configured and stored in the device before message viewing is needed. The system performs preliminary authentication checks automatically when the user attempts to access hidden message areas, rather than requiring complex multi-step verification processes at the moment of access. This preliminary setup reduces the operational burden on users during actual message viewing.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The message display system dynamically adjusts its behavior based on authentication status and check limits. When authentication succeeds and check limits have not been exceeded, the system provides full access to hidden message content. When limits are reached or authentication fails, the system dynamically restricts access and provides appropriate feedback. This dynamic response adapts to user actions in real-time, balancing security requirements with operational convenience.

Inventive Principle:
Principle #15Dynamics
