Camera Privacy Signal Detection and Obfuscation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The proliferation of small, integrated cameras has made it difficult for individuals and businesses to maintain privacy, as it is challenging to prevent unwanted recording of faces or restricted objects in public spaces.
Innovation Solution
A camera system equipped with a lens, processor, and memory that detects external recording restriction signals, determines the type of restriction, and either disables recording or obfuscates specific regions of the image/video based on the signal, ensuring compliance with privacy restrictions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If cameras are made small and integrated into daily devices, then camera portability and integration are improved, but privacy protection capability deteriorates
Solution Approach 1:
The patent introduces an intermediary mechanism (privacy management system with opt-out signals) that mediates between the camera's recording function and privacy protection requirements. This system allows individuals to actively signal when they do not wish to be recorded, creating a communication channel between subjects and recording devices without requiring physical camera control.
Solution Approach 2:
The patent changes the operational parameters of the camera system by introducing dynamic control based on external signals. The camera transitions from a static recording device to one that can dynamically adjust its recording behavior (continue, pause, or delete recordings) based on received opt-out signals, thereby adapting to privacy requirements in real-time.
2Productivity
If cameras continuously record in public spaces, then recording completeness is improved, but privacy restriction compliance deteriorates
Solution Approach 1:
The patent implements a feedback mechanism where the camera system receives opt-out signals from individuals and automatically adjusts its recording behavior in response. This closed-loop system allows the camera to maintain recording completeness for willing subjects while automatically complying with privacy restrictions when signals are received, resolving the contradiction between continuous recording and privacy compliance.
Solution Approach 2:
The patent makes the camera's recording behavior dynamic rather than static. The system can transition between different recording states (continuous recording, paused recording, or deletion of recordings) based on real-time conditions and received signals, allowing it to adapt its operation to balance recording completeness with privacy compliance.
3Object-affected harmful factors
If cameras disable recording to respect privacy signals, then privacy protection is improved, but recording functionality deteriorates
Solution Approach 1:
The patent applies local quality control by allowing the camera to maintain different recording behaviors for different subjects or time periods. Rather than completely disabling recording functionality, the system can selectively continue recording some subjects while respecting privacy signals for others, or temporarily pause recording only when signals are received, thereby protecting privacy while preserving overall recording functionality.

AI summary
Cameras and image processing methods for respecting recording restrictions are described, including a camera with at least one lens, at least one processor, and memory. The camera can detect an external signal; determine that the external signal indicates a restriction in recording; and based on the restriction, either disable recording or record an image or a video with a region of the image obfuscated.
