Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In multiple-device access environments, users lack a straightforward method to remotely log out or unregister communication devices not physically present, leading to security concerns as unauthorized access can occur, allowing eavesdropping and data theft.

Innovation Solution

A system and method that enables a user to selectively log out of registered communication devices via an Internet Protocol (IP) address or Media Access Control (MAC) address directly from a registered communication device, without requiring a third-party web interface, allowing users to manage their device registrations through a user-friendly interface.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If multiple communication devices are registered with the same extension to enable simultaneous access, then user accessibility and convenience are improved, but security risks and unauthorized access potential increase

Engineering Contradiction:

Improveuser accessibilityVSAvoidunauthorized access

Core Design Contradiction:

Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system provides real-time feedback to users about which devices are currently registered and active. Through a web interface, users can view the status of all registered devices and receive notifications about login events, enabling them to monitor and control device access actively

Inventive Principle:

Principle #23Feedback

Solution Approach 2:

A web-based interface serves as an intermediary between users and the communication devices. This intermediary allows users to remotely manage device registrations, view device status, and control access without needing physical access to the devices themselves

Inventive Principle:

Principle #24Intermediary (Mediator)

2Reliability

If users can remotely logout devices without physical access, then security control is improved, but system complexity increases due to additional management interfaces

Engineering Contradiction:

Improvesecurity controlVSAvoidmanagement interface

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The web interface provides multiple functions in a single unified system: viewing registered devices, monitoring device status, performing logout operations, and receiving notifications. This multi-functional approach consolidates what could be multiple separate systems into one accessible interface

Inventive Principle:

Principle #6Universality (Multi-functionality)

Solution Approach 2:

The system enables users to perform device management operations themselves without requiring administrator intervention or physical access to devices. Users can independently register, monitor, and logout devices through the web interface, empowering end-users to manage their own access control

Inventive Principle:

Principle #25Self-service

3Ease of operation

If continuous device registration is maintained for accessibility, then user convenience is improved, but exposure to eavesdropping and data theft increases

Engineering Contradiction:

Improvedevice accessibilityVSAvoiddata theft risk

Core Design Contradiction:

Ease of operationVSObject-generated harmful factors

Solution Approach 1:

Device registration status is made dynamic rather than static. Devices can be registered and active during business hours, then automatically or manually logged out during non-business hours or when not in use. This dynamic approach allows the system to adapt registration status based on user needs and security requirements

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system enables users to proactively logout devices before potential security threats arise. Users can remotely terminate device sessions in advance, particularly during non-business hours or when traveling, preventing unauthorized access before it can occur rather than reacting to security incidents after they happen

Inventive Principle:

Principle #10Preliminary action

AI summary

Methods and systems are provided for remotely logging out one or more registered communication devices associated with a common extension through a requesting communication device in the registered communication devices. The requesting communication device renders a list of registered communication devices associated with the extension of a user to a display. The user of the requesting communication device selects at least one of the registered communication devices, by a touch input at the display, to unregister the at least one registered communication device from the extension. In response, a message is automatically sent from the requesting communication device to a server to update the registration status of the selected at least one registered communication device. The server then terminates the registration of the at least one registered communication device from the extension associated with the user restricting the at least one registered communication device from accessing the extension.
