Solution Overview

Problem

Existing biometric systems, such as those described in JP-A-2005-6259, limit the utilization of biometric data to within a single apparatus and do not facilitate its use across multiple devices or applications.

Innovation Solution

An information processing apparatus that includes a biometric data input unit, storage for setting data, a processing unit to set and execute tasks based on the biometric data, and a transmission unit to send the biometric data to external devices, allowing the data to be used across multiple applications.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If biometric data is used only within the same apparatus, then security and data privacy are maintained, but functionality and versatility are limited

Engineering Contradiction:

Improvebiometric data utilization scopeVSAvoidsystem architecture

Core Design Contradiction:

Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent introduces a server as an intermediary component that facilitates biometric data sharing between multiple apparatuses. The server receives biometric data from one apparatus and transmits it to other apparatuses, enabling cross-device functionality while maintaining centralized control and security management.

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The biometric data acquisition unit is designed to capture multiple types of biometric data (fingerprint, iris, voice, etc.), and the system architecture allows this data to be utilized across different apparatuses and applications, making the system multi-functional and versatile rather than device-specific.

Inventive Principle:

Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If biometric data is transmitted to external devices, then functionality across multiple applications is enabled, but security risks increase

Engineering Contradiction:

Improvecross-device functionalityVSAvoiddata security

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system incorporates feedback mechanisms where the server verifies the authenticity and appropriateness of biometric data before transmitting it to external apparatuses. This feedback loop ensures that only verified and authorized data is shared, maintaining security while enabling cross-device functionality.

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

The patent implements different security handling for different types of biometric data and different transmission scenarios. Sensitive data is encrypted during transmission, and the server applies selective data sharing based on the specific requirements of each external apparatus, ensuring appropriate security levels for each context.

Inventive Principle:

Principle #3Local quality

3Ease of operation

If setting data is stored corresponding to biometric data, then user-specific processing is enabled, but data management complexity increases

Engineering Contradiction:

Improveuser-specific processingVSAvoiddata management

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The server acts as an intermediary that manages the storage and retrieval of setting data corresponding to biometric data. This centralized data management approach simplifies the architecture by consolidating data handling operations, making user-specific processing easier while reducing the complexity at individual apparatuses.

Inventive Principle:

Principle #24Intermediary (Mediator)
