Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing authentication systems struggle to suitably collect necessary biometric information based on a user's movement due to improper user responses to movement instructions, making it difficult to accurately determine impersonation by non-living objects.

Innovation Solution

An information processing apparatus and method that includes a movement instruction unit to guide users through specific movements, an information acquisition unit to capture and evaluate biometric data, and a display control unit to adjust instructions based on user movement, ensuring proper data collection for impersonation determination.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If the user is instructed to move according to a challenge, then the authentication process can proceed, but the user may be unable to move properly in accordance with the particular instruction

Engineering Contradiction:

Improveauthentication reliabilityVSAvoiduser movement execution

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system provides real-time feedback by displaying the user's current movement status and comparing it with the expected movement pattern. The display control unit shows visual indicators that guide the user to adjust their movement, ensuring proper execution of the challenge while maintaining authentication reliability.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system performs preliminary actions by pre-displaying guidance information and expected movement patterns before the user executes the challenge. This preparation helps users understand what movement is required, reducing the likelihood of improper execution and ensuring successful authentication.

Inventive Principle:

Principle #10Preliminary action

2Loss of information

If the user cannot move properly in accordance with the instruction, then the movement execution is difficult, but the system still needs to collect necessary biometric information

Engineering Contradiction:

Improvebiometric information qualityVSAvoiduser movement execution

Core Design Contradiction:

Loss of informationVSEase of operation

Solution Approach 1:

The display control unit provides continuous feedback showing the user's movement status and guiding them to improve their movement execution. This ensures that sufficient biometric information is captured while making the operation easier to understand and execute.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The system dynamically adjusts the guidance and display based on the user's real-time movement status. This adaptability allows the system to collect high-quality biometric information while accommodating varying user abilities and providing appropriate guidance throughout the process.

Inventive Principle:

Principle #15Dynamics
