Streaming Media Identification via Encrypted Network Traffic Correlation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing media monitoring technologies struggle to accurately identify streaming media on media presentation devices due to encrypted network traffic data and the introduction of streaming devices that complicate network traffic analysis, leading to unclear representation of media streaming activities.
Innovation Solution
A combined network and media presentation device metering system is employed, correlating network traffic data with streaming data to generate a traffic profile, using audio and video signatures, watermarks, and additional metrics to identify and report streaming media on devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If network traffic data is encrypted to secure communication, then security is improved, but the ability to accurately identify and analyze media streaming activities deteriorates
Solution Approach 1:
The patent segments the identification process into multiple independent components: extracting network traffic features (IP addresses, ports, protocols), extracting media presentation features (audio/video signatures, watermarks), and correlating these segmented features to identify media. This segmentation allows each component to operate independently, with the correlation step bridging the gap between encrypted network data and media identification.
Solution Approach 2:
The patent introduces an intermediary correlation process that connects network traffic data with media presentation device data. This intermediary mechanism uses traffic profiles and feature matching to bridge the gap between encrypted network communications and the actual media being streamed, enabling identification without requiring decryption of the network traffic itself.
2Adaptability or versatility
If streaming devices are introduced to enable flexible media access, then adaptability is improved, but the complexity of network traffic analysis deteriorates
Solution Approach 1:
The patent segments the system into distinct functional components: network meters that collect traffic data, media presentation device meters that capture audio/video signatures, and central facilities that correlate this data. This segmentation simplifies the overall complexity by allowing each component to perform a specific function rather than requiring a single complex analysis system.
Solution Approach 2:
The patent creates a universal monitoring framework that can identify media across multiple device types (smart TVs, smartphones, tablets, streaming devices) and multiple media sources (broadcast, internet streaming, local files). The correlation mechanism is designed to be device-agnostic, handling diverse streaming scenarios through a unified approach that reduces analysis complexity.
3Measurement precision
If combined network and device metering is implemented to improve identification accuracy, then measurement precision is improved, but device complexity deteriorates
Solution Approach 1:
The patent divides the metering system into separate network meters and media presentation device meters, each collecting specific types of data. This segmentation allows for specialized data collection at each point, improving the quality and precision of the data while keeping each individual meter relatively simple in design and function.

AI summary
Methods, apparatus, systems, and articles of manufacture are disclosed herein to identify media presentation by analyzing network traffic. Example instructions cause a machine to generate a traffic profile to reduce a computational burden of identifying streaming media being presented on a media presentation device, the traffic profile including first network traffic data indicative of the streaming media; obtain the traffic profile and second network traffic data corresponding to the streaming media; and generate, in response to a score for the second network traffic data meeting a threshold of similarity, a network traffic analysis report identifying the streaming media being presented on the media presentation device.
