Analysis and detection method and system for traffic hijacking in popularization of Android system application

The invention discloses an analysis and detection method and system for traffic hijacking in popularization of an Android system application. The detection method can be divided into a server and a client. In the detection process, the client collects data and submits the data to the server, and developers can analyze the data in multiple aspects at the server and master various characteristics oftraffic hijacking. According to the invention, the crowdsourcing technology is utilized to ensure the high availability and correctness of the collected data, and at the same time, the detection traffic of the client is effectively reduced in combination with part downloading technologies, so that the traffic overhead of participants can be significantly reduced and the traffic hijacking detection efficiency is improved; after hijacking is found, the source, severity, hijacking mode and the like of hijacking behaviors can be analyzed at the server by utilizing a big data technology, so that responsibility tracing is
