Solution Overview

Problem

Mobile terminals face challenges in securely providing and accessing security information without requiring users to remember complex passwords or authentication details, posing risks of privacy exposure due to lost or misplaced devices.

Innovation Solution

A mobile terminal system that recognizes subjects through a camera, processes preview images to identify relevant security information, and performs authentication using various methods such as fingerprint scanning, password input, or face recognition to securely output security-set information, allowing authorized access while reducing user inconvenience.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If users are required to remember complex passwords or authentication details for security, then security is improved, but user convenience deteriorates and memory burden increases

Engineering Contradiction:
ImprovesecurityVSAvoiduser convenience
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The terminal automatically retrieves and provides security information without requiring users to remember or manually input complex authentication details. The system serves itself by storing security information locally and automatically providing it when needed, eliminating the memory burden on users while maintaining security through authorized access.

Inventive Principle:
Principle #25Self-service

Solution Approach 2:

The terminal acts as an intermediary between the user and the security information. Instead of users directly remembering and inputting complex passwords, the terminal mediates by storing the security information and providing it automatically during authentication processes, thus improving convenience while maintaining security.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of operation

If security information is stored in the terminal to enable automatic provision, then user convenience is improved, but the risk of privacy exposure increases if the terminal is lost or misplaced

Engineering Contradiction:
Improveuser convenienceVSAvoidprivacy exposure risk
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The security information is segmented into different categories (e.g., payment information, personal information, account credentials) and stored in a structured manner within the terminal. This segmentation allows for selective provision of only the necessary security information during authentication, minimizing the exposure of sensitive data while maintaining user convenience.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

Different security information is stored with different security characteristics and access controls within the terminal. The system applies local quality by providing different levels of protection and access conditions for different types of security information, ensuring that only authorized information is provided during authentication while maintaining overall security.

Inventive Principle:
Principle #3Local quality

3Ease of operation

If multiple authentication methods are provided (fingerprint, password, face recognition), then user convenience and accessibility are improved, but device complexity increases

Engineering Contradiction:
ImproveaccessibilityVSAvoidauthentication system complexity
Core Design Contradiction:
Ease of operationVSDevice complexity

Solution Approach 1:

The terminal is designed with multi-functionality by integrating multiple authentication methods (fingerprint sensor, password input interface, face recognition camera) into a single device. This universal approach allows the terminal to serve multiple authentication purposes using different biometric or cryptographic methods, improving accessibility while managing complexity through integrated design.

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

AI summary

A mobile terminal including a camera provided at a terminal body; a touch screen configured to output a preview image received through the camera; and a controller configured to perform an authentication process associated with an object included in the preview image and for obtaining security-set information for operating the object included in the preview image, and output the security-set information when the authentication process is successfully performed based on input authentication information.
