Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Conventional meeting systems require users to manually input passwords using keyboards, which is inconvenient and compromises security when using password authentication schemes that prioritize ease of access.

Innovation Solution

An information processing system that selects an authentication scheme based on meeting information, allowing users to authenticate passwords via voice input during the meeting, enhancing convenience without compromising security.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a password authentication scheme is used to protect file security, then security is improved, but ease of operation deteriorates due to manual keyboard input requirements

Engineering Contradiction:

Improvefile securityVSAvoidpassword input convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent replaces the mechanical keyboard input system with a voice recognition system. The voice input device captures spoken passwords, and the voice recognition processor converts speech to text for authentication, eliminating the need for physical keyboard interaction while maintaining security.

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

Solution Approach 2:

The patent introduces a voice recognition processor as an intermediary between the user's spoken password and the authentication system. This intermediary component processes and converts voice inputs into authenticated credentials, bridging the gap between convenient voice input and secure password verification.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If a simple authentication scheme is used to improve convenience, then ease of operation is improved, but security deteriorates

Engineering Contradiction:

Improveaccess convenienceVSAvoidfile security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The patent changes the input modality parameter from manual keyboard entry to voice-based input. This parameter change maintains the security of password authentication while significantly improving ease of operation, as voice input is more convenient than typing during meetings.

Inventive Principle:

Principle #35Parameter changes

3Ease of operation

If voice input authentication is implemented during meetings, then ease of operation is improved, but device complexity increases

Engineering Contradiction:

Improvepassword input convenienceVSAvoidauthentication system complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent makes the existing voice recognition processor, which is already part of the meeting system for other functions, serve the additional function of password authentication. This multi-functional approach improves ease of operation without significantly increasing device complexity, as the same hardware component handles both meeting operations and security authentication.

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

An information processing system includes a file acquirer that acquires a file used in a meeting, an authentication processor that selects, if a password is set to the file acquired by the file acquirer, an authentication scheme of the password, based on meeting information about the meeting, and executes a process of authenticating the password by the selected authentication scheme, and a file executer that executes the file if the password is authenticated by the authentication processor.
