Edge Privacy Control Using Sensor-Based Risk Assessment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for protecting user privacy and data on edge devices are either overly restrictive or inaccurate, failing to provide adequate security in varying environments.
Innovation Solution
A system utilizing a combination of sensors, a sensor aggregator, policy agent, and risk agent to dynamically assess the environment and adjust application usage based on sensitivity and security thresholds, enabling granular privacy protection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If applications require strong authentication credentials and trusted device connections, then security level is improved, but ease of operation deteriorates
Solution Approach 1:
The system dynamically adjusts security measures based on real-time environmental context detected by sensors. Instead of static authentication requirements, the system adapts security levels according to the detected environment, making the security approach dynamic rather than fixed. This resolves the contradiction by making security adaptive to context rather than universally restrictive.
Solution Approach 2:
The system changes security parameters based on environmental conditions detected by sensors. When the environment is deemed safe, security restrictions are relaxed; when unsafe conditions are detected, security measures are intensified. This parameter adjustment based on environmental context resolves the contradiction between maintaining high security and ensuring ease of operation.
2Measurement precision
If sensor data is used to determine environmental safety, then measurement precision is improved, but device complexity increases
Solution Approach 1:
The system combines data from multiple existing sensors (camera, infrared camera, Bluetooth, Wi-Fi, microphone) that are already present in modern edge devices. By merging the functionality of these existing sensors for security assessment purposes, the system achieves precise environmental measurement without adding significant device complexity, as it leverages already-integrated components.
Solution Approach 2:
The system makes existing multi-functional sensors serve additional security assessment functions. Sensors originally designed for other purposes (camera for photos, microphone for audio) are utilized for environmental safety detection. This multi-functionality approach improves measurement precision while avoiding the need for dedicated security sensors that would increase device complexity.

AI summary
A system or method for dynamically protecting a user's confidential information and a user's privacy at an edge device can include a plurality of sensors operatively coupled to the edge device, memory and one or more processors configured to perform certain operations. The operations can include aggregating signals from two or more sensors among the plurality of sensors via a sensor aggregator to provide an aggregated signal, setting policies via a policy agent that gives weighting factors to the two or more sensors and further assigns a security threshold level to one or more applications, calculating risks via a risk agent based on the policies set and readings from the two or more sensors, and orchestrating the sensor aggregator, the policy agent and the risk agent via a tracker application to modify a user interface interaction with each application operating on or via the edge device.
