Data-secure sensor system with I/O choke
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Home security cameras are vulnerable to hacking, preventing users from installing them in sensitive areas due to concerns about unauthorized access to video data, which limits their effectiveness in monitoring important or private spaces.
Innovation Solution
A data-secure system that processes sensor data to generate descriptive information about objects or activities without exposing raw video data externally, using a hardware choke to limit communication bandwidth and employing machine learning for enhanced security, ensuring that only processed data is shared, thereby maintaining privacy.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If home security cameras are installed to monitor sensitive areas, then surveillance capability is improved, but security vulnerability increases due to hacking risks
Solution Approach 1:
The system segments data into two categories: raw sensor data (video) and processed descriptive data. Only descriptive data is made accessible externally, while raw sensor data remains isolated within the trusted environment. This segmentation allows surveillance functionality while eliminating the security vulnerability of exposing raw video streams.
Solution Approach 2:
A processor acting as an intermediary converts raw sensor data into descriptive data before external transmission. This intermediary processing step ensures that even if external access is compromised, the actual sensor data never leaves the secure environment, as only processed information is exposed.
2Ease of operation
If raw video data is made accessible for remote viewing, then user convenience is improved, but data security deteriorates due to potential unauthorized access
Solution Approach 1:
Instead of transmitting original video data, the system creates a copy in the form of descriptive data that captures the essential information (object identification, activity type) without containing the actual video content. This copying approach maintains user convenience for monitoring while eliminating security risks associated with exposing raw video streams.
3Reliability
If cameras are placed in private areas for monitoring, then monitoring effectiveness is improved, but privacy protection worsens due to potential data breaches
Solution Approach 1:
The system extracts only the essential monitoring information (descriptive data about objects and activities) from the raw sensor data, leaving the sensitive video content behind in the secure environment. This extraction allows effective monitoring of private areas while removing the privacy violation risk associated with storing or transmitting actual video footage.
Data Source
AI summary
In some embodiments, a data-secure sensor system includes one or more processors configured to receive sensor data (e.g., image data, audio data, etc.) and generate descriptive data based on the sensor data that corresponds to a physical area that corresponds to information about identified objects or activity in physical area, an input/output (I/O) port, and an I/O choke communicatively coupled between the one or more processors and the I/O port, the I/O choke configured to limit a communication bandwidth of the I/O port to a maximum data rate. The one or more processors can be configured to prevent the sensor data from being accessible via any external port of the data-secure camera system, including the I/O port, and allow the descriptive data to be accessible via the I/O port.
