Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing security keyboard technologies are vulnerable to malicious third-party interception, as they do not effectively verify the legitimacy of callers, allowing potential theft of personal information during electronic financial transactions.

Innovation Solution

A security keyboard system and method that generates and verifies unique verification values based on call event counts, using a mutually agreed algorithm between the caller and security keyboard modules, to ensure only legitimate calls are responded to, thereby preventing unauthorized access.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a security keyboard is displayed on the screen for electronic financial transactions, then user authentication can be performed, but a malicious third party may call the security keyboard to steal personal information

Engineering Contradiction:

Improvesecurity of personal informationVSAvoidtheft of personal information by malicious third party

Core Design Contradiction:

ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The system performs preliminary verification of the caller's identity before allowing access to the security keyboard. A verification value is generated and compared with a stored reference value to ensure the caller is legitimate before personal information can be input, preventing malicious third parties from stealing information.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The verification value acts as an intermediary mechanism between the caller and the security keyboard. This intermediate verification step ensures that only authorized callers can access the keyboard, mediating the interaction and preventing direct access by malicious entities.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If verification values are generated and compared for each call event, then unauthorized access is prevented, but system complexity increases

Engineering Contradiction:

Improveverification of legitimate callsVSAvoidcomplexity of verification process

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

Instead of creating complex verification systems, the patent uses a simplified approach where a verification value is generated based on the call event and compared with a pre-stored reference value. This copying and comparison method provides reliable verification while maintaining relatively simple system architecture.

Inventive Principle:

Principle #26Copying

AI summary

Disclosed is a security keyboard executing method, and an apparatus and system for performing the same. A security keyboard system according to an embodiment of the present disclosure includes: a caller module configured to generate a first verification value in response to a call event for a security keyboard, and generate a security keyboard call signal which includes the first verification value and caller identification information; and a security keyboard module configured to receive the security keyboard call signal, generate a second verification value based on the security keyboard call signal, and verify a security keyboard call by comparing the first verification value and the second verification value.
