Privacy Manager for Video Stream Resolution Adjustment
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile devices collect sensitive data that can uniquely identify individuals, posing privacy risks, especially when high-resolution video streams reveal health conditions, which can be analyzed by computing devices, potentially breaching privacy during interactions like video calls.
Innovation Solution
A wireless carrier network system that monitors sensor data and adjusts settings, such as reducing video stream resolution, using privacy sensors, models, and rules to mitigate privacy breaches by encrypting data streams and altering settings to prevent unauthorized analysis of sensitive information.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Illumination intensity
If high-resolution video streams are transmitted, then communication quality is improved, but privacy breach risk increases due to ability to analyze health conditions
Solution Approach 1:
The system dynamically changes the resolution parameter of video streams based on privacy risk assessment. When health conditions are detected in video content, the system automatically reduces resolution to prevent detailed analysis while maintaining communication functionality. This parameter adjustment resolves the contradiction by adapting video quality to privacy requirements in real-time.
Solution Approach 2:
The wireless carrier network acts as an intermediary between the communicating parties, monitoring video streams for privacy risks and automatically adjusting resolution when threats are detected. This intermediary function allows the system to protect privacy without requiring direct user intervention or compromising communication quality when no threats exist.
2Adaptability or versatility
If sensor data collection is enhanced, then device functionality is improved, but privacy exposure increases due to unique identification capability
Solution Approach 1:
The system adjusts sensor data collection parameters dynamically based on context and privacy risk. When communication involves potential privacy threats, the system modifies which sensors are active and at what resolution, reducing data collection to minimum necessary levels while maintaining essential device functionality for communication.
Solution Approach 2:
The system implements partial data collection by selectively activating sensors and adjusting their resolution based on privacy requirements. Instead of continuously collecting maximum data from all sensors, the system collects only the minimum necessary data for the current communication context, reducing privacy exposure while maintaining functionality.
3Object-affected harmful factors
If data encryption is implemented, then privacy protection is improved, but communication complexity increases
Solution Approach 1:
The system performs preliminary privacy risk assessment and automatically configures encryption and resolution settings before communication begins. By pre-evaluating the communication context and pre-configuring appropriate privacy protections, the system eliminates the need for complex real-time decision-making during communication, reducing operational complexity while maintaining strong privacy protection.

AI summary
Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for implementing a privacy manager are disclosed. In one aspect, a method includes the actions of receiving, from a client device, an indication of a first setting of the client device. The actions further include receiving, from the client device, an indication of a type of data that the client device is prepared to transmit. The actions further include, based on the first setting and the type of data, generating an instruction to adjust the first setting or a second setting of the client device. The actions further include, before the client device transmits the data, providing, for output to the client device, the instruction to adjust the first setting or the second setting of the client device.
