Biometric Authentication Output Mapping for Privacy-Safe User Confirmation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing authentication technologies, such as those disclosed in Patent Documents 1 and 2, do not adequately protect the privacy of authenticated individuals while providing a clear authentication result, often leading to physiological burdens due to direct face image display or insufficient identification of the user.
Innovation Solution
An information processing system that acquires biological information, generates output information corresponding to identification information, and outputs it in a form that is difficult to associate with the individual, such as shape or color information, while ensuring confidentiality through display on a mobile terminal or integrated display.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of information
If face images or direct identification information are displayed to show authentication results, then authentication clarity is improved, but privacy protection deteriorates
Solution Approach 1:
The patent extracts only the essential authentication result information (authenticated/not authenticated) from the complete biological information, displaying only this extracted result while keeping the full biological information secure. This separates the authentication outcome from the sensitive personal data, providing clear feedback without exposing privacy.
Solution Approach 2:
The patent introduces an intermediary processing step that converts raw biological information into authenticated/not authenticated results through pattern matching and comparison. This intermediary layer acts as a buffer between the sensitive biological data and the display output, ensuring privacy protection while maintaining authentication clarity.
2Loss of information
If face images are displayed for authentication results, then user identification is improved, but physiological burden increases
Solution Approach 1:
The patent extracts only the authentication outcome (authenticated/not authenticated) from the biological information, eliminating the need to display face images. This extraction approach provides sufficient user identification for authentication purposes while removing the source of physiological burden associated with face image display.
Solution Approach 2:
The patent uses temporary, non-permanent display of authentication results without retaining or displaying permanent facial images. The authentication result is presented as a transient state (authenticated/not authenticated) rather than as a persistent visual record, reducing the physiological impact on users.

AI summary
An information processing system acquires biological information of a target and generates output information determined in correspondence with identification information using the identification information associated with the biological information. Then, the output information is output.
