Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

There is a need for a secure method to prevent unauthorized copying of sensitive electronic data, such as document files, image files, or video files, within a networked environment.

Innovation Solution

A system that rapidly changes the pixel configurations of sensitive data displayed on a user's device, using a series of frames with altered attributes like saturation, hue, and brightness, making it unreadable in still captures while remaining readable in real-time viewing, and incorporates embedded microtags to track unauthorized reproductions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If pixel configurations are rapidly changed at high frequency to prevent unauthorized copying, then security against unauthorized reproduction is improved, but readability for legitimate users may deteriorate

Engineering Contradiction:

Improvesecurity against unauthorized reproductionVSAvoidreadability for legitimate users

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

The system dynamically changes pixel configurations at high frequency (e.g., 60Hz or higher) to prevent unauthorized reproduction while maintaining readability for legitimate users through temporal persistence of vision effects

Inventive Principle:

Principle #15Dynamics

Solution Approach 2:

The system employs periodic frame updates with designated intervals between frames, creating a temporal pattern that allows human perception of continuous imagery while preventing static capture of readable content

Inventive Principle:

Principle #19Periodic action

2Reliability

If multiple frames with altered pixel attributes are generated and displayed sequentially, then unauthorized reproduction is prevented through illegibility in still captures, but device complexity increases

Engineering Contradiction:

Improveprotection against unauthorized reproductionVSAvoidsystem complexity for frame generation and management

Core Design Contradiction:

ReliabilityVSDevice complexity

Solution Approach 1:

The system segments the display content into multiple sequential frames with different pixel configurations, where each frame individually appears illegible but the sequence conveys the complete information to legitimate users

Inventive Principle:

Principle #1Segmentation

Solution Approach 2:

The system uses an intermediary processing layer that generates and manages multiple frames with altered attributes, acting as a mediator between the original content and the display output to prevent direct copying

Inventive Principle:

Principle #24Intermediary (Mediator)

3Measurement precision

If embedded microtags are incorporated in the data to track unauthorized reproductions, then detection capability is improved, but manufacturing precision requirements increase

Engineering Contradiction:

Improvedetection capability of unauthorized reproductionVSAvoidprecision for embedding and detecting microtags

Core Design Contradiction:

Measurement precisionVSManufacturing precision

Solution Approach 1:

The system embeds microtags within the pixel data structure in a nested manner, where the microtag information is concealed within the same data container as the visible content, requiring precise extraction and analysis

Inventive Principle:

Principle #7Nested doll (Nesting)

AI summary

A system is provided for detection and mitigation of unauthorized reproduction of sensitive electronic data. In particular, the system may comprise a networked environment with various computing devices that may be used to store, process, and/or transfer sensitive electronic data. When a user accesses the sensitive data, the contents of the data may be presented as a series of micro dots or pixels. The system may be configured to display rapidly change at least a portion of the micro dots or pixels at a high frequency, such that a snapshot of the sensitive data taken at a singular point in time will not be able to capture all of the data needed to make the data readable to the user. In this way, the system may be able to prevent the unauthorized reproduction of sensitive data within the network environment.
