In order to get useful data, it researches the network sniffing technology based on Raw Socket and mainly studies the technology of protocol analyze and data recombine. And it introduces the Trojan horse technique to the network data collection part, improves the process hiding technique, uses the triple-thread technique, and so on. It ensures the imperceptibility and stability of the network data collection part. Then this paper develops pseudo hypertext transfer protocol based on HTTP. This protocol is used in the communication between the network data collection part and the service part, which make the communication more covert.
