Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In existing communication systems, users' personal information, such as telephone numbers, is inadvertently exposed during call initiation, leading to privacy concerns and potential misuse, particularly in illicit activities like voice phishing.

Innovation Solution

A communication terminal and method that reads tag information from objects, including a terminating number, to initiate calls without displaying the terminating number, using a control unit to manage the display of termination display information and store originating records excluding the terminating number, thereby protecting user privacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Loss of information

If the telephone number is displayed during call initiation, then the caller can identify the recipient, but the personal information is exposed to unauthorized persons

Engineering Contradiction:

Improveprivacy protectionVSAvoidcall initiation

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The patent extracts the sensitive terminating number from the display interface while maintaining its functional use in call routing. The control unit separates the display function from the data function, allowing the number to be used for calling without being shown to the user or exposed externally.

Inventive Principle:

Principle #2Taking out (Extraction)

Solution Approach 2:

The control unit acts as an intermediary between the calling process and the display interface. It manages the terminating number internally, preventing direct exposure to unauthorized persons while still enabling the call to be initiated and routed correctly.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If the terminating number is stored in the communication terminal, then the call can be initiated, but the personal information can be misused for illicit activities

Engineering Contradiction:

Improvecall processingVSAvoidprivacy vulnerability

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent applies local quality by restricting the visibility and accessibility of the terminating number to specific internal components only. The control unit and communication unit can access the number for call processing, but the display unit and external interfaces do not show or expose it, creating different access qualities for different system components.

Inventive Principle:

Principle #3Local quality

3Loss of information

If the telephone number is displayed on the terminal, then the caller can see the recipient information, but the information is inadvertently exposed to unauthorized persons

Engineering Contradiction:

Improveinformation exposureVSAvoiddisplay control

Core Design Contradiction:

Loss of informationVSDevice complexity

Solution Approach 1:

Instead of displaying the terminating number as in conventional systems, the patent inverts the approach by hiding the number and using alternative identification methods. The control unit manages the display to show caller information or other non-sensitive data while keeping the terminating number concealed from external view.

Inventive Principle:

Principle #13The other way round (Inversion)

AI summary

A method, communication terminal and system for processing a communication call are provided, the communication terminal including a reader configured to obtain tag information by reading a tag attached to an object the tag information comprising a terminating number; a communication unit configured to transmit a request for an originating call based on the terminating number; and a control unit configured to control the communication terminal to display termination display information corresponding to one of the obtained tag information and the transmitting of the request for originating the call, wherein the termination display information excludes the terminating number.
