Solution Overview

Problem

Existing IoT technologies face challenges in maintaining user privacy when displaying information on public devices, as previous solutions require specialized equipment or cannot distinguish user information from dummy information effectively, especially in crowded areas where others may inadvertently view private data.

Innovation Solution

A system that transmits user information alongside dummy information to public displays, making them indistinguishable to onlookers, using indicators and visual patterns for user recognition, and synchronizing haptic feedback to ensure privacy protection without needing modified devices or ID tags.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Ease of operation

If user information is displayed on public display devices, then users can access information without checking their mobile devices, but privacy is compromised as onlookers can view the information

Engineering Contradiction:
Improveease of information accessVSAvoidprivacy exposure
Core Design Contradiction:
Ease of operationVSObject-affected harmful factors

Solution Approach 1:

The system creates dummy information that copies the format, structure, and visual appearance of genuine user information. This dummy information is displayed alongside or instead of real information on public displays, making it visually indistinguishable to onlookers while protecting the actual user data.

Inventive Principle:
Principle #26Copying

Solution Approach 2:

The system applies different qualities to different parts of the displayed information by introducing subtle visual variations between genuine and dummy information. These local differences (such as slight formatting variations, timing differences, or positional variations) allow the user to distinguish their information while maintaining overall visual similarity to protect privacy.

Inventive Principle:
Principle #3Local quality

2Object-affected harmful factors

If dummy information is displayed alongside user information to protect privacy, then privacy is protected, but it becomes difficult for users to distinguish their information from dummy information

Engineering Contradiction:
Improveprivacy protectionVSAvoidinformation identification
Core Design Contradiction:
Object-affected harmful factorsVSDifficulty of detecting and measuring

Solution Approach 1:

The system uses feedback mechanisms where the mobile device communicates with the public display to provide real-time cues to the user. When genuine information is displayed, the mobile device receives a corresponding signal, allowing the user to identify their information through the feedback loop between the display and device.

Inventive Principle:
Principle #23Feedback

Solution Approach 2:

The system employs periodic display patterns where genuine user information is shown at specific intervals or times, while dummy information is displayed at different times. This temporal differentiation allows users to identify their information through the periodic nature of its appearance without compromising overall privacy protection.

Inventive Principle:
Principle #19Periodic action

3Device complexity

If standardized public display devices are used, then device complexity is reduced, but the ability to provide synchronized haptic feedback and visual patterns is limited

Engineering Contradiction:
Improvedisplay device requirementsVSAvoidinformation synchronization
Core Design Contradiction:
Device complexityVSReliability

Solution Approach 1:

The system introduces a software intermediary layer that runs on standard mobile devices and coordinates communication between the public display and the user's device. This intermediary enables synchronized haptic feedback, visual patterns, and timing without requiring specialized hardware modifications to either the display or mobile device.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The system makes standard mobile devices perform multiple functions by using their existing sensors, processors, and output capabilities for synchronization purposes. The mobile device serves as both the primary information source and the feedback reception device, eliminating the need for specialized equipment while maintaining reliable synchronization.

Inventive Principle:
Principle #6Universality (Multi-functionality)
