Solution Overview

Problem

Conventional home network systems fail to provide user profile information accumulated over time to external devices, limiting the ability to offer personalized services outside the home based on a user's living patterns, inclinations, and preferences.

Innovation Solution

A service providing method and system that connects a user device with an external device through a network, using encryption and authentication to securely transfer and access user profile information from a profile server, allowing authorized external devices to receive relevant user data for providing tailored services.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If user profile information is stored only in home server, then data security and privacy are maintained, but personalized services cannot be provided outside home

Engineering Contradiction:

Improveservice availability outside homeVSAvoiddata security risk

Core Design Contradiction:

Adaptability or versatilityVSObject-affected harmful factors

Solution Approach 1:

The system divides profile information into multiple segments: complete profile stored securely at home server, and selective profile portions transmitted to external devices only when needed. This segmentation allows services outside home while maintaining security through controlled data distribution.

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The invention introduces an intermediary authentication and authorization mechanism between the home server and external devices. This intermediary verifies device credentials, manages access rights, and controls profile information transmission, enabling secure external service delivery without direct exposure of sensitive data.

Inventive Principle:

Principle #24Intermediary (Mediator)

2Adaptability or versatility

If complete profile information is transmitted to external devices, then personalized services are enabled, but data confidentiality and access control are compromised

Engineering Contradiction:

Improvepersonalization capabilityVSAvoiddata confidentiality

Core Design Contradiction:

Adaptability or versatilityVSReliability

Solution Approach 1:

The system applies local quality by transmitting only the specific profile portions required for each external service, rather than complete profile data. Each external device receives customized data subsets based on its specific service requirements, enabling personalization while minimizing data exposure and maintaining confidentiality.

Inventive Principle:

Principle #3Local quality

Solution Approach 2:

The invention implements partial action by selectively transmitting only the necessary profile information segments needed for specific external services, rather than transmitting all profile data. This partial transmission approach enables sufficient personalization for each service while preserving data confidentiality by limiting exposure to only what is strictly required.

Inventive Principle:

Principle #16Partial or excessive action

3Reliability

If authentication mechanisms are implemented for profile access, then data security is improved, but system complexity and access overhead increase

Engineering Contradiction:

Improvedata securityVSAvoidauthentication system complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system performs preliminary authentication and authorization actions before profile information transmission. Devices are pre-registered and authorized with specific access rights to required profile segments. This preliminary setup enables subsequent efficient access without repeated complex authentication, balancing security with reduced operational overhead.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The authentication mechanism is designed as a universal system that handles multiple functions: device registration, credential verification, authorization management, and access control. This multi-functional approach consolidates security operations into a single integrated mechanism, reducing overall system complexity while maintaining comprehensive security coverage.

Inventive Principle:

Principle #6Universality (Multi-functionality)
