Solution Overview

Problem

Existing communication systems for television conferences lack effective security measures to restrict participation, allowing unauthorized terminals to join sessions and requiring cumbersome pre-registration processes.

Innovation Solution

A communication system that includes a participation determination unit to authenticate and permit participation based on matching participation authentication information, allowing secure and easy restriction of session participants.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If participation restriction is implemented by pre-registering participants before the conference, then security is improved, but device complexity and ease of operation deteriorate due to cumbersome registration processes

Engineering Contradiction:

ImprovesecurityVSAvoidease of operation

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system performs preliminary actions by having the conference organizer pre-configure participation restriction settings and generate authentication information before the conference starts. This allows participants to join without manual registration, as the authentication information is automatically validated against pre-configured participant lists, thereby maintaining security while simplifying the joining process.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The conference terminal acts as an intermediary that manages participation restrictions by holding and verifying authentication information. Instead of requiring direct pre-registration of each participant, the conference terminal mediates access by automatically validating incoming participants against pre-configured authentication data, thus improving ease of operation while maintaining security.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Ease of operation

If any terminal registered in the destination list can participate in the conference, then ease of operation is improved, but security deteriorates as unauthorized parties cannot be prevented from participating

Engineering Contradiction:

Improveease of operationVSAvoidsecurity

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system applies different quality levels of access control to different participants. The conference organizer has full access to configure participation restrictions, while regular participants have limited access requiring authentication verification. This localized differentiation of access rights allows easy operation for authorized users while maintaining security through selective authentication requirements.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The conference terminal serves as an intermediary that verifies participation authentication information before allowingJoining. Even though terminals are registered in the destination list for ease of operation, the intermediary conference terminal validates each participant's authentication information against pre-configured data, thereby maintaining security without compromising operational simplicity.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Reliability

If participation authentication information is verified by comparing notified and input information, then security is improved, but device complexity increases due to additional authentication mechanisms

Engineering Contradiction:

ImprovesecurityVSAvoiddevice complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The conference terminal performs self-service by automatically generating, storing, and verifying participation authentication information without requiring external authentication servers or complex third-party systems. The terminal itself manages the authentication process by comparing notified authentication information with input information, thereby improving security while minimizing device complexity through self-contained authentication functionality.

Inventive Principle:

Principle #25Self-service

AI summary

In the present invention, a start request terminal transmits start request information including participation restriction information to a management system. A transmission/reception unit of the management system transmits participation authentication information for authenticating participation in an established session to a middle-of-conference participation terminal. A transmission/reception unit of a participation request terminal transmits, to the management system, participation request information for requesting participation of the participation request terminal in an established session and participation authentication information which is input with the terminal in accordance with the participation authentication information transmitted to the terminal. A participation determination unit of the management system compares the participation request information received from the participation request terminal and the participation authentication information corresponding to the participating terminal in a terminal management table, and determines whether to permit the participation request terminal to participate in the established session.
