Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple biometric recognition methods are integrated, then authentication reliability is improved, but the complexity of score integration increases
Solution Approach 1:
The patent transforms multiple different types of biometric scores (face recognition scores, iris recognition scores, etc.) into a unified integrated score by changing their parameter representation. The score integration unit calculates an integrated score that synthesizes multiple biometric verification results, converting heterogeneous authentication data into a homogeneous evaluation metric that can be uniformly thresholded and compared.
2Speed
If simple score integration is used, then processing speed is improved, but measurement precision of authentication result deteriorates
Solution Approach 1:
The patent incorporates feedback mechanisms where the score integration unit uses threshold comparison results to determine authentication outcomes. The system compares the integrated score against predetermined thresholds and provides feedback-based decision-making, allowing accurate authentication judgments while maintaining efficient processing through automated threshold-based classification.

AI summary
An information processing apparatus includes: a first score acquiring unit that acquires a first score indicating a matching score of first biometric recognition using first biometric information about a target; a second score acquiring unit that acquires a second score indicating a matching score of second biometric recognition using second biometric information about the target; a reference data acquiring unit that acquires reference data about at least one of the first biometric recognition and the second biometric recognition; and an integrated score calculation unit that calculates an integrated score on the basis of the first score, the second score, and the reference data. According to the information processing apparatus, it is possible to properly calculate the integrated score.
