Abstract

The invention provides an identification method and a system of a VPN application under an Android system. The method comprises the following steps of through a VpnService characteristic, preliminarily screening and acquiring a batch of Apps; for the screened Apps, using a keyword to match App information and identifying a matched App as a target App; for the residual unmatched Apps, according tothe distribution of the same type of Apps, determining whether the Apps are the target Apps; for the non-targeting Apps, according to a trigger level of the type which VpnService belongs to in an Appcode, determining the Apps directly serving the main function of the corresponding Apps instead of the auxiliary function and the Apps that need to establish connection with a remote server during a VPN establishment process to be the target Apps; and carrying out labeling analysis on flow data during an App operation process and screening VPN service end ip:port information. In the invention, theApp serving breakthrough access restrictions in massive Apps can be conveniently and automatically screened.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and system for identifying VPN applications under the Android system. Background technique [0002] Starting from Android 4.0 (API LEVEL 15), it is a solution to help APP establish a VPN connection on the device through the VpnService framework. VpnService allows APP to conveniently intercept all sent and received data packets on the device. Therefore, apps based on VpnService have various functions, and not all VPN apps are used to break through access restrictions. For example, roughly classified into: VPN Clients, Enterprise, Traffic Optimizer, CommunicationTools, Traffic filters, Traffic logger, Antivirus, Tor clients, etc. Typical representatives of each category, such as packet capture in the Traffic logger category, use VpnService to capture traffic on Android devices; Baidu Mobile Guard, 360 Mobile Assistant in Antivirus, etc. use VpnService to t...
