Solution Overview

Problem

Existing user authentication systems for in-home displays require users to visit an administration center for confirmation, causing inconvenience.

Innovation Solution

A method using a mobile terminal to transmit authentication request data to an authentication server, displaying a confirmation message on the in-home display, and performing user authentication to permit access, eliminating the need for physical visits.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If user visits administration center for authentication, then authentication reliability is improved, but user convenience deteriorates

Engineering Contradiction:

Improveauthentication reliabilityVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The patent introduces a mobile terminal as an intermediary device between the user and the authentication system. The mobile terminal stores authentication information and communicates with both the user and the authentication server, eliminating the need for the user to physically visit the administration center while maintaining secure authentication processes

Inventive Principle:

Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent replaces the mechanical process of physical visitation to the administration center with an electronic authentication system. Authentication is performed through digital communication between the mobile terminal and authentication server, substituting the mechanical travel and manual verification process with automated electronic verification

Inventive Principle:

Principle #28Mechanics substitution (Replace mechanical system)

2Reliability

If user visits administration center for authentication, then authentication security is improved, but authentication time increases

Engineering Contradiction:

Improveauthentication securityVSAvoidauthentication time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The patent implements preliminary action by pre-storing authentication information in the mobile terminal before the actual authentication event. This allows the authentication process to proceed directly through electronic communication without requiring the user to travel to the administration center, significantly reducing authentication time while maintaining security through pre-verified credentials

Inventive Principle:

Principle #10Preliminary action

3Ease of operation

If authentication is performed through mobile terminal, then user convenience is improved, but system complexity increases

Engineering Contradiction:

Improveuser convenienceVSAvoidsystem complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The patent applies universality by designing the mobile terminal to serve multiple functions: it acts as an authentication credential storage device, a communication interface with the authentication server, and a user interface for authentication requests. This multi-functionality consolidates several system components into a single universal device, managing complexity while improving convenience

Inventive Principle:

Principle #6Universality (Multi-functionality)

AI summary

A system for authenticating a user of an in-home display (IHD) and an authentication method are provided. A user of an IHD is authenticated by using a mobile terminal including an authentication application. The authentication system receive authentication request data from the mobile terminal and allows the IHD to display a message in relation to user confirmation, and when certain requirements are met, the authentication system performs user authentication to permit a user to use the IHD.
