Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

Existing radio-television systems lack effective privacy protection for users, particularly when multiple users share the same device and content availability notifications may be sent to the wrong user, leading to inappropriate content access.

Innovation Solution

A method for generating messages about radio-television programs that requires user credential verification, incorporating parameters like user category, content category, and time constraints to ensure privacy, using devices like terrestrial receivers, HbbTV, and Smart TVs with face/voice/gesture recognition for secure authentication.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Device complexity

If query results are displayed without user verification, then system simplicity is maintained, but user privacy is compromised

Engineering Contradiction:

Improvesystem simplicityVSAvoiduser privacy protection

Core Design Contradiction:

Device complexityVSReliability

Solution Approach 1:

The system performs preliminary user credential verification before displaying query results. The radio-television apparatus checks whether the currently logged-in user matches the user who created the query, and only displays results if verification succeeds. This preliminary action ensures privacy protection is built into the system workflow without requiring complex additional components.

Inventive Principle:

Principle #10Preliminary action

2Reliability

If user credential verification is implemented, then user privacy is protected, but system complexity increases

Engineering Contradiction:

Improveuser privacy protectionVSAvoidsystem complexity

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system uses the existing logged-in user context to automatically verify identity without requiring additional user interaction. The verification process leverages the already-authenticated user session, eliminating the need for separate login prompts or complex authentication interfaces, thus minimizing added system complexity while maintaining privacy protection.

Inventive Principle:

Principle #25Self-service

3Productivity

If background querying is enabled, then content availability is improved, but inappropriate content access risk increases

Engineering Contradiction:

Improvecontent availabilityVSAvoidinappropriate content access

Core Design Contradiction:

ProductivityVSObject-affected harmful factors

Solution Approach 1:

The system implements a feedback mechanism where query results are only displayed after successful user verification. When a query is created in background mode, the system stores the querying user's identity and later verifies it before displaying results. This feedback loop ensures that even though background querying improves content availability, inappropriate access is prevented by confirming the user's identity before revealing results.

AI summary

A method is described, together with the associated radio-television apparatus and system, for generating messages, comprising information about radio-television programs, in reply to a query made by a radio-television apparatus on one or more radio-television program databases and/or on the Internet, wherein the messages are issued on the basis of a user's privacy criterion; said privacy criterion requiring at least the verification of a user's credentials.
