Problems solved by technology

[0005] From the behavioral characteristics and feasibility analysis of malicious applications, the security check of sending information is not perfect. Malicious application developers can use service (the name of the program running in the background) technology to run malicious sending information programs in the background, illegally steal local information, and send Send information to a specific destination address; you can also use the background to continuously send information, causing economic losses to users
[0006] In order to prevent the losses caused by the above-mentioned malicious applications to users, since the android1. Sending, however, this kind of prevention method only prevents from setting the amount of information to be sent, which has great limitations. When a problem is found, the user needs to be reminded, and the user needs to make a judgment every time, and the interaction with the user is poor

[0058] figure 1 A schematic flowchart of a method for defending malicious information transmission by a mobile smart terminal according to the first embodiment of the present invention is given. The steps of this embodiment will be described in detail below with reference to the accompanying drawings:

[0059] Judging step (110), when the application program of the mobile intelligent terminal is to send information, it is judged whether the sending object of the information is in the preset blacklist or whitelist;

[0060] In the processing step (120), if it is judged to be in the preset blacklist, then block the sending of the information; if it is judged to be in the preset whitelist, then allow the sending of the information.

[0061] Wherein, the blacklist is a list of application software not trusted by the smart mobile terminal; the white list is a list of application software trusted by the smart mobile terminal.

[0062] Each application program can be set in the trus...

Abstract

The invention discloses a malicious information transmission preventing method and system of a mobile intelligent terminal. The method comprises the following steps of: judging, namely judging whether an information transmission object is in a preset blacklist or whitelist or not when the application program of the mobile intelligent terminal is about to transmit information; and processing, stopping the transmission of the information if the information transmission object is in the preset blacklist and allowing the transmission of the information if the information transmission object is in the preset whitelist, wherein the blacklist is a list of application software untrusted by the mobile intelligent terminal, and the whitelist is a list of application software trusted by the mobile intelligent terminal. By applying the method and system disclosed by the invention, the transmission of the malicious information can be efficiently prevented.

Description

technical field [0001] The present invention relates to the technical field of mobile intelligent terminals, in particular to a method and system for preventing malicious information transmission of mobile intelligent terminals. Background technique [0002] At present, with the development and application of various operating systems, smart terminal products are replacing traditional electronic products more and more quickly, and these terminal products include mobile phones, tablet computers, notebook computers, and the like. The existing operating systems used in smart terminal products mainly include PalmOS, Symbian, Windows mobile, Linux, Android, iPhoneOS, BlackBerry, etc. [0003] Among them, Android is an open source mobile phone operating system based on the linux kernel. Since the official birth of Android, due to its open source, a large number of mobile phone applications have appeared. When Android was launched, Google designed certain security measures for pos...
