Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing input methods, such as touch screens and keypads, expose user passwords to unwanted observation, as the movement of fingers can be visually detected, compromising the security of personal information during input.

Innovation Solution

An input device and method that utilizes a tactile output signal to determine the input time point of information, allowing the device to recognize user-input information only after a tactile signal is generated, thereby protecting the input from exposure.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If a key input device such as a touch screen or keypad is used for password input, then convenience of operation is improved, but visual exposure of the password to third parties occurs

Engineering Contradiction:

Improveconvenience of password inputVSAvoidvisual exposure of password

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The patent introduces a tactile signal as an intermediary between the user's key input and the device's recognition of the input. The tactile signal serves as a mediator that triggers the device to recognize subsequent inputs as password information, thereby preventing visual exposure while maintaining operational convenience

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The device performs a preliminary action by generating a tactile signal before recognizing the actual password input. This preliminary tactile cue prepares the user for input while the device waits for the subsequent password entry, creating a time window that prevents visual observation of the input process

Inventive Principle:

Principle #10Preliminary action

2Reliability

If the device waits for tactile signal confirmation before recognizing input, then password security is improved, but input time is increased

Engineering Contradiction:

Improvepassword securityVSAvoidinput time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent implements periodic action by using a brief, timed tactile signal that occurs at specific intervals during the input process. The tactile signal is generated for a limited duration, creating a structured time window for input recognition that balances security requirements with time efficiency

Inventive Principle:

Principle #19Periodic action

Solution Approach 2:

Once the tactile signal is generated and the user provides input within the expected time window, the device quickly processes and recognizes the input without prolonged waiting. The system skips extended verification delays and proceeds efficiently once the tactile-triggered input condition is met

Inventive Principle:

Principle #21Skipping (Rushing through)

AI summary

An input device and method for protecting input information from exposure, in which the time of input of information is determined using a tactile output to protect the input information from being exposed. The input device for protecting input information from exposure includes a user-input module for receiving predetermined input information from a user, a control module for setting the information inputted in association with a tactile signal among the input information as user-input information, and a tactile-output-generation module for generating and providing the tactile signal to the user-input module under the control of the control module.
