Privacy Protection Of Intelligent Devices Based On VPN Technoloy

With the development of electronic technology,the Internet is now the most impormant way to communicate and gain information,smart mobile devices are the easiest way to access the Internet.In fact,more and more people rely on smart devices to communicate,sports,trading and so on.Their private information will be collected with smart devices.If a backdoor software is installed in the device,much private information is revealed.SO,we designed "mobile phone privacy protection system" to protect the user's privacy."Mobile privacy protection system" is to create a virtual network adapter provided by VPNService technology of Android system.You can get all network traffic(IP packets)on the device at the IP layer through the virtual network adapter.IP packet information may be parsed by the IP Parser to obtain header information and data information.In order to keep a communication,we also define an intermediate agent to transmit data.IP Reconstructor will be written a response into the virtual network adapter.Corresponding methods of all plugins will be called to filter this traffic by the system.With plugins,we can easily set up own analysis tools."Mobile privacy protection system" does not require root permissions to run on a device and does not require any knowledge about VPN from user either.According to out test,the system can effectively detect privacy leakages and make a reasonable overhead.
