Integrated Camera Privacy Mode for Attribute-Only Sensing
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional camera technologies on smart devices raise privacy concerns as they may record users without knowledge or consent, and existing solutions like physical shutters and LED indicators are inadequate for user awareness and dual-use cases.
Innovation Solution
A privacy enhancement mode that allows user-controlled camera operation, enabling dual use as a sensor for user attribute detection (movement, motion, gesture, mood) while preventing image broadcast, using an inference engine and hardware-based indicators to ensure privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the camera is kept engaged to support dual-use cases (video conferencing and attribute detection), then the camera functionality and versatility are improved, but user privacy and security are worsened due to potential unauthorized recording
Solution Approach 1:
The patent segments the camera system into distinct operational modes: a first mode for video conferencing where video data is processed and transmitted, and a second mode for attribute detection where only processed attributes are transmitted. This segmentation allows the camera to maintain versatility while preventing unauthorized recording by ensuring that in the second mode, only non-identifiable attributes leave the device.
Solution Approach 2:
The patent introduces an intermediary processing layer that receives video data from the camera, extracts attributes (such as movement, gesture, mood), and transmits only these attributes to the server. This intermediary acts as a mediator between the camera sensor and the network transmission, enabling dual-use functionality while protecting privacy by preventing raw video data from being transmitted when not needed.
2Object-affected harmful factors
If physical shutters are used to block the camera, then user privacy is improved, but the camera cannot support use cases that do not require video uploading
Solution Approach 1:
The patent implements dynamic mode switching that allows the camera to transition between different operational states based on user needs. Rather than a static physical shutter that permanently blocks the camera, the system dynamically adjusts its operation between video conferencing mode and attribute detection mode, maintaining camera functionality while protecting privacy when needed.
Solution Approach 2:
The patent changes the operational parameters of the camera system by introducing different data processing and transmission configurations for different modes. In the first mode, video data is fully processed and transmitted; in the second mode, only extracted attributes are transmitted. This parameter change approach allows the same hardware to serve multiple purposes without physical modification.
3Loss of information
If LED indicators are used to show camera status, then user awareness is improved, but the indicators only show ON/OFF status and do not show what the camera is doing
Solution Approach 1:
The patent uses different LED colors to indicate different operational modes of the camera system. For example, one color indicates video conferencing mode is active, another color indicates attribute detection mode is active. This color-coding system provides intuitive visual feedback that communicates not just whether the camera is on, but what specific function it is performing, improving both user awareness and information accuracy.
Applied Scientific Principles

AI summary
The disclosure generally relates to method, system and apparatus for privacy enhancement mode for integrated cameras. In an exemplary embodiment, the disclosure allows a user of a device equipped with an integrated device to engage the device in the so-called privacy mode whereby while the camera is engaged, the device does not broadcast the user's images; rather the device uses the camera to detect, discern and determine the user's attributes. Such attributes may include one or more of movement, motion, mood, gesture and temperature of the user. The attributes may include specificities of the user's environment.
