Privacy Proxy Device Granular IoT Data Control
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Individual IoT users lack control and knowledge over the data collected by Internet of Things (IoT) devices, leading to over-collection of private data, which can be harmful and erode consumer trust.
Innovation Solution
A privacy proxy device is introduced, equipped with a transceiver, processor, and memory, which stores and enforces privacy settings, monitors data collection, and analyzes messages to detect and prevent privacy violations, allowing users to control and monitor data collection in real-time.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If conventional IoT systems offer control only over destination IP address and domain, then device communication control is simplified, but fine granularity control for privacy considerations is insufficient
Solution Approach 1:
The patent segments privacy control into multiple granular levels including destination IP address, domain, port, protocol type, and data category. This segmentation allows users to control data flow at increasingly fine-grained levels, transforming the coarse control of conventional systems into precise privacy management capabilities.
Solution Approach 2:
The system dynamically adjusts control granularity based on user preferences and privacy policies. Users can configure different levels of detail for different scenarios, allowing the control mechanism to adapt between simplified operation and fine-grained privacy management depending on the specific use case.
2Quantity of substance
If IoT devices continuously collect data, then data availability for useful purposes increases, but user knowledge and control over data collection decreases
Solution Approach 1:
The privacy proxy device implements a feedback mechanism that continuously monitors data collection activities and provides real-time information to users about what data is being collected, where it is going, and under what policies. This feedback loop restores user knowledge about data flows that would otherwise be invisible in continuous collection scenarios.
Solution Approach 2:
The patent introduces a privacy proxy device as an intermediary between IoT devices and data destinations. This intermediary transparently inspects data flows, enforces privacy policies, and provides users with visibility and control over data collection activities, thereby maintaining user knowledge while preserving continuous data availability.
3Measurement precision
If privacy proxy device analyzes messages in real-time, then privacy violation detection capability improves, but processing time and system complexity increase
Solution Approach 1:
The system performs preliminary actions by pre-configuring privacy policies, data categories, and enforcement rules before actual data flows occur. This preparation allows the privacy proxy to make rapid decisions during real-time message analysis without needing to perform complex evaluations for each individual data packet, thereby reducing processing time while maintaining detection accuracy.
4Adaptability or versatility
If fine granularity privacy control is implemented, then user control over data collection improves, but device complexity and configuration difficulty increase
Solution Approach 1:
The privacy proxy device serves multiple functions including data flow monitoring, policy enforcement, user interface provision, and detailed logging all within a single device. This multi-functionality consolidates what would otherwise require multiple separate components, making fine-grained privacy control accessible without proportionally increasing overall system complexity.
Data Source
AI summary
A privacy proxy device for maintaining privacy on a communication network is provided. The privacy proxy device includes a transceiver, a processor, and a memory. The transceiver communicates with at least one user device and at least one device capable of recording over a communication medium of the communication network. The memory store computer-executable instructions, which, when executed by the processor, cause the privacy proxy device to store a plurality of privacy settings including one or more recording settings. The instructions further cause the privacy proxy device to receive a request to record from a recording device of the at least one device capable of recording. The instructions also cause the privacy proxy device to compare the request to record to the plurality of privacy settings. In addition, the instructions cause the privacy proxy device to generate and transmit a response to the request to record based on the comparison.
