Solution Overview

Problem

The increasing use of text messaging functions has led to a rise in damage from malicious text messages, particularly SMiShing, which tricks recipients into clicking links or calling back numbers, resulting in software downloads, personal information exposure, and small payments.

Innovation Solution

A method and apparatus that notify users of potential SMiShing by transmitting message-related information to a SMiShing detection server, receiving SMiShing-related information, and displaying it alongside the message, including thumbnail images for links and SMiShing histories to help users recognize risks.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Speed

If users directly open links in received text messages, then message processing speed is improved, but security risk increases due to SMiShing attacks

Engineering Contradiction:
Improvemessage processing speedVSAvoidSMiShing damage
Core Design Contradiction:
SpeedVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary detection of text messages and generates SMiShing-related information (including thumbnail images of links and SMiShing history) before the user opens the message. This advance preparation allows the message to be displayed immediately with security information already in place, eliminating the delay that would occur if detection were performed after message opening.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent introduces a SMiShing detection server as an intermediary between the user's electronic device and the malicious content. The server receives text messages, analyzes them for SMiShing characteristics, and returns security information including thumbnail images that visually represent the link destination. This intermediary layer enables fast message display while maintaining security through pre-analysis.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Use of energy by moving object

If SMiShing detection is performed after opening the message, then device resource consumption is reduced, but user response time increases

Engineering Contradiction:
Improvedevice energy consumptionVSAvoiduser response time
Core Design Contradiction:
Use of energy by moving objectVSLoss of time

Solution Approach 1:

The system performs SMiShing detection and generates thumbnail images in advance, before the user opens the message. This preliminary action shifts the computational burden to a background process that occurs while the user is composing or viewing other content, so when the message is opened, the detection is already complete and results are immediately available.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent replaces the traditional approach of real-time local analysis with a cloud-based detection system. The electronic device sends messages to a remote SMiShing detection server for analysis, substituting local mechanical processing with remote computational resources. This reduces local energy consumption while maintaining fast response times through efficient communication protocols.

Inventive Principle:
Principle #28Mechanics substitution (Replace mechanical system)

3Measurement precision

If thumbnail images are generated for all links, then detection accuracy is improved, but processing time increases

Engineering Contradiction:
ImproveSMiShing detection accuracyVSAvoidthumbnail generation time
Core Design Contradiction:
Measurement precisionVSLoss of time

Solution Approach 1:

The system applies different processing qualities to different parts of the message analysis. Thumbnail images are generated at a standardized resolution suitable for display purposes rather than full image quality, and only for links that are suspected of being malicious based on initial analysis. This localized quality adjustment maintains detection accuracy while reducing overall processing time.

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent implements partial thumbnail generation by creating thumbnails only for links that meet certain risk criteria rather than all links in every message. The system performs initial filtering to identify suspicious links, then generates thumbnails only for those cases, reducing unnecessary processing while maintaining detection accuracy for actual threats.

Inventive Principle:
Principle #16Partial or excessive action
