Fingerprint Authentication Control Unit Partial Matching

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional fingerprint authentication systems do not allow operation by a finger other than the registered finger, limiting usability while maintaining security.

Innovation Solution

An information processing apparatus with a reader unit, collating unit, and control unit that permits input operations by a finger whose fingerprint information is not fully registered, allowing operation by a finger with coincident fingerprint information among multiple readings.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If fingerprint authentication is performed by collating read fingerprint information with registered fingerprint information, then security is maintained, but operation by unregistered fingers is not permitted

Engineering Contradiction:

ImprovesecurityVSAvoidoperability

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent applies partial action by permitting input operations when at least one piece of fingerprint information among multiple simultaneously read pieces coincides with registered fingerprint information, rather than requiring all pieces to match. This allows operation by unregistered fingers (partial matching) while maintaining security through the presence of at least one authentic fingerprint match.

Inventive Principle:

Principle #16Partial or excessive action

2Reliability

If only registered fingerprint information is accepted for authentication, then security is ensured, but usability is limited

Engineering Contradiction:

ImprovesecurityVSAvoidusability

Core Design Contradiction:

ReliabilityVSAdaptability or versatility

Solution Approach 1:

The system allows partial matching where operation is permitted if at least one of multiple simultaneously read fingerprint pieces matches registered information. This provides adaptability by accepting operations with unregistered fingers while maintaining security through the requirement of at least one authentic match among the multiple readings.

Inventive Principle:

Principle #16Partial or excessive action

AI summary

An information processing apparatus is capable of allowing an operation by a finger of which a fingerprint has not been registered, and of improving operability while holding security. A collating unit collates fingerprint information about a finger that touched a touch panel read by a reader unit with registered fingerprint information. A control unit permits an operation to the touch panel by the finger when the fingerprint information read is coincident with the registered fingerprint information, and does not permit the operation when the fingerprint information read is not coincident with the registered fingerprint information. The control unit permits an operation to the touch panel by a finger of which fingerprint information is not coincident with the registered fingerprint information when at least one piece of fingerprint information among a plurality of pieces of fingerprint information that the reader unit reads simultaneously is coincident with the registered fingerprint information.
