AI Technical Summary

Technical Problem

Existing technologies struggle to effectively identify and differentiate encrypted live video traffic, especially in live streaming scenarios. Traditional methods are costly or rely on high-quality training datasets and cannot achieve fine-grained video scene recognition.

Method used

By employing the Sr-Sketch data structure and peak point features combined with a causal inference model, and through DNS packet analysis and traffic feature extraction, we can identify live video traffic and determine its type.

🎯Benefits of technology

It enables early and rapid identification and accurate classification of encrypted live video traffic, improves identification efficiency, overcomes the dependence on the quality of the training dataset, and can identify specific live video types.

Abstract

The application belongs to the field of network security and management, and provides a live broadcast scene-oriented encrypted video traffic identification method, system, device and storage medium. The method comprises the following steps: identifying the DNS request domain name of the obtained DNS data packet to obtain traffic data belonging to the live video type domain name; performing a matching operation on the domain name of the traffic data and the domain name in the prior knowledge base; if the traffic data can be matched, the traffic data is live video stream data, and the stream level features of the traffic data are extracted; otherwise, the persistence and frequency of the traffic data in each period are calculated, the importance of the traffic data is calculated according to the persistence and frequency of the traffic data in each period; when the importance in the final period is higher than the importance threshold, the traffic data is regarded as live video stream data, and the stream level features are extracted; and the video type is identified based on the stream level features and a causal reasoning model.
