Problems solved by technology

This operation reduces the security of the user's device and increases the possibility of spreading virus programs; some major Android device manufacturers will also refuse to provide quality assurance for the devices they sell because users have performed "root" operations by themselves

Embodiment Construction

[0034] The present invention will be described in further detail below through specific implementation examples and in conjunction with the accompanying drawings.

[0035] Such as figure 1 As shown, the present invention provides a data packet filtering method under the non-superuser authority of the Android system, comprising the steps of:

[0036] S101: Read the data packets intercepted by the pre-started virtual kernel device TUN according to the default routing strategy;

[0037] S102: Determine the application program APP to which the data packet belongs according to the IP quintuple of the above data packet;

[0038] S103: Determine the filtering rule for the data packet according to the preset filtering rule table and the application program APP to which the data packet belongs;

[0039] S104: Filter the data packet according to the filtering rule.

[0040] In some embodiments, instead of using the default routing strategy in step S101 , a designated routing table ma...

Abstract

The invention relates to the technical field of mobile communication, in particular to a data package filtering method, device and system for an Android system under non-super user authority. The data package filtering method for the Android system under non-super user authority includes the steps that a data package intercepted by a pre-started virtual kernel device TUN according to a default route strategy is read; an application program APP to which the data package belongs is determined according to IP five tuples of the data package; according to a preset filtering rule list and the application program APP to which the data package belongs, a filtering rule of the data package is determined; according to the filtering rule, the data package is filtered. According to the data package filtering method for the Android system under non-super user authority, the data package is filtered according to the filtering rule list and based on a default rule or requirements of a user, and selective network communication is achieved; meanwhile, the method can be achieved under non-super user authority, security of user equipment is improved, and the probability of propagation of virus programs is reduced.

Description

technical field [0001] The present invention relates to the technical field of mobile communication, in particular, to a data packet filtering method, device and system under non-super user authority of an Android system. Background technique [0002] Smart mobile devices based on the Android system, represented by Android phones, are currently one of the main Internet access devices. Android devices access the Internet mainly through wireless local area networks and mobile cellular data networks (GPRS, CDMA, 3G, 4G, etc.). Due to the wireless network access service provider's policy of charging according to the communication traffic, the use of mobile cellular data networks may incur high communication fees, so most Android device users need to manage the network communication of the device. The Android system provides the user function of connecting and disconnecting the mobile data network, but this basic management function of full on and full off cannot meet the needs ...
