Conference Call Authorization Transfer Mechanism

Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing conference call systems face security issues due to unauthorized participants joining calls, often resulting from uncontrolled forwarding of invitations, which can compromise the security and integrity of scheduled meetings.

Innovation Solution

A conference call server is configured to manage participant authorizations, allowing only authorized devices to join by using unique identifiers like device PINs or mobile identifiers for authentication, and enabling the transfer of participant authorization from one device to another while revoking access from the original invitee, ensuring only one participant can join per invitation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If invitation forwarding is allowed for flexibility, then ease of operation is improved, but security deteriorates due to unauthorized participants

Engineering Contradiction:

Improveinvitation forwarding flexibilityVSAvoidconference call security

Core Design Contradiction:

Ease of operationVSReliability

Solution Approach 1:

The system performs preliminary actions by assigning unique identifiers to invitations and tracking authorization transfers before the conference call occurs. This prevents unauthorized access by establishing control mechanisms in advance, allowing flexible forwarding while maintaining security through pre-configured authorization tracking.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback mechanisms by monitoring invitation forwarding and authorization transfers in real-time. The conference call server tracks which devices hold valid authorizations and can prevent or alert about unauthorized join attempts, enabling flexible operation while maintaining security through continuous monitoring and control.

Inventive Principle:

Principle #23Feedback

2Adaptability or versatility

If multiple devices can join per invitation for flexibility, then adaptability is improved, but security deteriorates due to uncontrolled access

Engineering Contradiction:

Improveparticipant flexibilityVSAvoidaccess control security

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system segments authorization into unique, transferable units tied to specific invitations and devices. Each authorization is distinct and traceable, allowing multiple participants while maintaining control. This segmentation enables flexible participation through authorized transfers while preventing uncontrolled access through individual authorization tracking.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The conference call server acts as an intermediary that mediates all authorization transfers and join requests. It validates each transfer, tracks current authorization holders, and controls access to the conference call. This intermediary mechanism enables adaptable participant management while ensuring security through centralized control and validation.

Inventive Principle:

Principle #24Intermediary (Mediator)

3Ease of operation

If invitation forwarding is unrestricted for convenience, then ease of operation is improved, but loss of information deteriorates regarding participant tracking

Engineering Contradiction:

Improveinvitation transfer convenienceVSAvoidparticipant authorization tracking

Core Design Contradiction:

Ease of operationVSLoss of information

Solution Approach 1:

The system creates and tracks unique copies of authorization tied to each invitation and device. Rather than losing track of participants during forwarding, the system generates traceable authorization copies that maintain links to the original invitation and current holder. This enables convenient unrestricted forwarding while preventing information loss through comprehensive tracking of each authorization copy.

Inventive Principle:

Principle #26Copying

AI summary

A method for transferring participation authorization for a scheduled conference call. A conference call server includes a memory for storing conference call scheduling information with respect to a scheduled conference call session, the conference call scheduling information including participant authorizations for eligible communication devices of the scheduled conference call session. The method includes: receiving, in a first communication device, an invitation message containing at least some of the conference call scheduling information with respect to the scheduled conference call session, displaying an interface in relation to the scheduled conference call session, the interface including an option to transfer participant authorization for the scheduled conference call session to a second communication device, and sending a communication to the conference call server for adding participant authorization of the second communication device and removing participant authorization of the first communication device.
