Due to the rapid update of mobile applications, the characteristics of network traffic may change greatly, which leads to the degradation of network traffic classification model. The network traffic classification model requires accurate labelled data sets. Therefore, it is necessary to build high quality network traffic ground truth for mobile applications. This paper suggests an automated ground truth collection system for mobile application traffic, called MAT-GT, which can collect the network traffic of mobile applications and quickly construct accurate ground truth. It contains four components: controller engine, capture engine, traffic process engine and noise filter engine. MAT-GT mainly uses the user identifier of application and netfilter log to collect and label traffic of the mobile applications. For the labelling of fine-grained behavior traffic, we propose to use the injection timing behavior labelling method to slice the traffic of the application. After the traffic traces processed, we combine the noise recognition model to filter out the noisy traffic in the dataset. Then, we accurately form labelled traffic data sets for 150 mobile applications and 33 behaviors traffic. Finally, we apply non-noisy application traffic datasets for mobile application traffic classification, which further verifies that the accurately labelled data set provided by our system can improve the classification effect of application traffic.
