Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
As smart devices increasingly integrate into home and work environments, there is a growing concern about unauthorized or inadvertent capture of private data, with users lacking control over recording or sensor activity.
Innovation Solution
A data protection system that includes a user device capable of generating private data, a smart device with sensors, and a shielding device. The system allows users to selectively shield private data by deactivating sensors or generating noise/signals to obscure data capture.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If smart devices continuously monitor and record environmental data, then data capture capability is improved, but privacy security deteriorates
Solution Approach 1:
The system applies preliminary anti-action by detecting when private data is being generated (such as during video calls or when sensitive applications are active) and proactively activating shielding outputs before unauthorized capture can occur. The shielding device emits signals or noise to prevent the smart device sensor from capturing private data in the first place, rather than attempting to remove or correct captured data later.
Solution Approach 2:
The system converts the potentially harmful continuous monitoring capability of smart devices into a beneficial privacy protection mechanism. The same sensor that could capture private data is utilized through its reverse function - the shielding device emits signals that exploit the sensor's detection capabilities to identify when shielding is needed, then uses emitted noise or interference signals to prevent harmful capture, thereby transforming the monitoring mechanism into a protective one.
2Object-affected harmful factors
If shielding device activates continuously to protect private data, then privacy security is improved, but energy consumption increases
Solution Approach 1:
The shielding device employs dynamics by transitioning between different operational states based on real-time conditions. The controller activates the shielding output only when private data generation is detected (such as when communication applications are in use or sensitive data is being processed), and deactivates it when no private data is being generated. This dynamic on-demand operation maintains privacy security during critical moments while minimizing energy consumption during normal periods.
Solution Approach 2:
The system implements periodic action through continuous monitoring of data generation patterns and periodic activation of shielding only during identified private data events. Rather than continuous operation, the shielding activates in periodic bursts synchronized with the detection of private data generation events, maintaining protection effectiveness while significantly reducing overall energy consumption compared to continuous shielding operation.
3Object-affected harmful factors
If sensor deactivation is used to prevent data capture, then privacy security is improved, but data gathering capability deteriorates
Solution Approach 1:
The system applies segmentation by dividing the operational time into distinct segments: periods when private data is being generated and periods when it is not. During private data generation segments, the sensor is deactivated or shielding is activated to prevent capture. During non-private data segments, normal data gathering operations resume without interference. This temporal segmentation allows the system to maintain both privacy security during sensitive periods and data gathering capability during normal periods.
Solution Approach 2:
The sensor deactivation mechanism uses dynamics by transitioning the sensor between active and inactive states based on real-time detection of private data generation. The controller dynamically adjusts sensor operation - deactivating only when and where private data is being generated, while maintaining active operation during normal data gathering periods. This dynamic state management preserves data gathering capability for legitimate purposes while preventing harmful capture during private data events.

AI summary
Provided is a data protection system that operates to shield private data from detection or communication over a network. In an embodiment, the system includes a shielding device that, when active, provides a shielding output that shields, e.g., obscures, detection of private data by sensors of smart devices. The shielding may be selectively activated such that active sensors of the smart devices may operate or detect environmental events normally during times outside of the shielding. A data protection tool of the system may remove or shield private data generated by a user device, e.g., by modifying captured image data.
