Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The integration of image and audio capture devices in portable electronics raises privacy and security concerns due to the risk of unauthorized access and surveillance, as users may not be aware when they are being recorded, and existing software-based security measures can be overcome.
Innovation Solution
Implementing hardware-based access controls through a locking component that physically secures image capture devices by disconnecting power sources and using LED indicators or augmented reality displays to notify users and bystanders of recording activity, ensuring secure data collection and preventing unwanted surveillance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If image and audio capture devices are integrated into portable electronics, then device functionality is improved, but privacy and security risks increase due to unauthorized access
Solution Approach 1:
The capture device is divided into separate functional components: an image capture component (camera) and an audio capture component (microphone), each with independent control mechanisms. This segmentation allows selective activation and independent security control of each sensor type, reducing the risk of unauthorized simultaneous access to both capture functions.
Solution Approach 2:
A locking component is introduced as an intermediary between the power source and the capture devices. This locking component physically controls power delivery to the image and audio capture components, acting as a hardware-based security barrier that prevents unauthorized operation even if software security is compromised.
2Reliability
If software-based security measures are implemented, then access control is provided, but security can be overcome by hacking
Solution Approach 1:
The patent replaces software-based security control with a hardware-based locking mechanism that physically controls power delivery to capture devices. This mechanical/electrical control system operates independently of the device's operating system and software, making it immune to software-based attacks, rooting, or jailbreaking that could compromise traditional security measures.
Solution Approach 2:
The locking component is configured to prevent power delivery to capture devices before unauthorized access can occur. By establishing hardware-level restrictions on power supply prior to any software execution, the system proactively blocks potential security breaches rather than reacting to them after software security is compromised.
3Loss of information
If users are notified of recording activity, then privacy awareness is improved, but device complexity increases with additional notification components
Solution Approach 1:
The notification system merges LED indicators with the existing power management circuitry. The same power management IC that controls power delivery to capture devices also drives the LED notification indicators, eliminating the need for separate notification hardware and reducing overall device complexity while maintaining privacy awareness functionality.
Solution Approach 2:
The power management IC performs multiple functions: it controls power delivery to image and audio capture components, monitors their operational state, and drives LED indicators to notify users of recording activity. This multi-functionality reduces the total component count and simplifies the device architecture while providing comprehensive privacy notification.

AI summary
Apparatuses and systems for electronic wearable devices such as smart glasses are described. The wearable device can comprise a housing, an image capture component, a locking component, and a control component. The housing defines an imaging aperture. The image capture component is coupled to the housing and aligned with the imaging aperture. The image capture component is configured to capture image data of a field of view aligned with the imaging aperture. The locking component is coupled to the image capture component. The locking component modifies a capture state of the image capture component to selectively enable image capture in response to a selection releasing the locking component. The control component is coupled to the locking component. Interaction with the control component comprises the selection releasing the locking component and triggering modification of the capture state of the image capture component.
