Be elaborated below by specific embodiment.
Step S201: terminal receives the data of wireless connections and is stored in register (101) by antenna;
Step S202: user's submit operation instructs with Request System allocating register data;
Call data to data from register (101) and feed back the preliminary examination that filtering module (102) carries out data.
Data feedback filtering modules (102) are equivalent to intelligent firewall, and data are carried out initial analysis, examination, and data are classified, and are divided into several grades according to threaten degree, and upload microprocessor (103); Through the data analysis sifting sort, with read-only class data file, can write class file and unknown class file, be uploaded to microprocessor (103) with different threaten degrees respectively and analyze judgement again, read-only class file threat level is minimum can directly to respond user's operation; Can write class file threaten degree middle rank, information such as the content that allows it to write and write, position are monitored, and then the corresponding information after user's operation are uploaded to terminal handler and carry out corresponding; Unknown class file is made as the threaten degree highest ranking, at first notify this file of user to exist great risk whether to be necessary to proceed again operation, if the user confirms to continue operation, then microprocessor (103) responds its operational order, file is written in the specific buffer memory, and uploads system processor with the read-only file form and operate corresponding.Wherein the data in the particular cache are subjected to real-time monitoring.
Step S203: the electric current situation of change in current monitoring control module (104) the monitor data transmission course;
When current monitoring control module (104) is not found the data exception transmission in terminal, data feedback filtering module (102) and power amplifier are carried out current monitoring, the variation of Monitoring Data electric current when transmission course, sample and report microprocessor analysis, and analysis result returned to monitor control system, analyze contrast in order to counter tracing later on.Current monitoring control module (104) is gathered corresponding data and is reported microprocessor analysis, and determines a corresponding current margin.Such as: the frequent range of current of seeking network under the range of current when audio-frequency current scope, the data service of user when using terminal to make a phone call opened and downloaded data, the poor signal situation, microprocessor analysis is handled the back and is determined a relatively reasonable value range, feeds back to current monitoring control module (104).These can realize that power-supply management system is preserved these information by software.
The user is in the process of using terminal, and screen must be illuminating state, and the electric current of all users in issuing the process of any instruction all can be bigger than normal more many than the electric current that terminal oneself response produces.Can effectively prevent the user under unwitting situation according to this difference, some privacies of individual are stolen by others.So when the detected electric current of current monitoring control module (104) is not in the scope of running current in this programme, send alarm to microprocessor.
Step S204: all operations request msg is fed back filtering module (102) by data and is uploaded microprocessor (104) (this is unique passage).
Step S205: microprocessor (104) is analyzed the data of summarizing and reporting, reports response user's operation requirement, and the threaten degree of operation is indicated.
Step S206: system processor is handled operation requests, realizes the operation purpose.
Step S207: when microprocessor does not receive the instruction of user's submission, find data feedback filtering module (102) reported data, open the anti-program of tracing; Perhaps, when microprocessor does not receive the instruction of user's submission, when receiving the alarm of current monitoring control module (104), open the anti-program of tracing.
Step S208: the data that microprocessor (103) reports according to data feedbacks filtering module (102) and current monitoring control module (104) are analyzed and are carried out the threaten degree judgement, just carry out different operational orders according to threaten degree, the agreement data transmission of rudimentary threaten degree, whether the prompting user of rudimentary threaten degree continues executable operations, direct command data feedback filtering modules (102) interception of senior threaten degree, the forbidden data transmission.
Step S210: close under the invalid situation of data feedback filtering modules (102), microprocessor directly directly cuts off electric current to the current monitoring control system, and with thorough prevention data transmission, disconnected end connects in all data in the external world.
In the subsequent step, after data feedback filtering modules (102) quit work, microprocessor (103) prompting user is introduced into offline mode, turn-on data is fed back filtering module (102) again, initial installation data and the abnormal data collected compare, and inform that with analyzing the system processor of reporting terminal as a result that comes out the user is the part that goes wrong.
Illustrate, for example: suppose certain software by user installation on terminal, begin not monitor any abnormal behaviour, when the user is in holding state, the outside receives an automatic activating software of data, and software begins response and outwards transmit data under the unwitting situation of user.As when this kind situation occurring, when software receives signal response, data are if outwards transmission, the power of power amplifier must increased power dissipation increase immediately, when current monitoring control module (104) monitors big electric current by finding not to report microprocessor inquiry terminal processor whether operation requests was arranged immediately when the preset range with the data comparison of collecting, current monitoring control module (104) is not before receiving instruction simultaneously, power amplifier, intelligent data feedback system are carried out current limliting, it guarantees data transmission, does not allow data send again.And send alarm prompt to the user.When confirming that the user does not carry out the automatic operation response instruction of any operating terminal, microprocessor (104) sends the request of cutting out data feedback filtering modules (103) to the user and stops the outside communication of program, do not make when response as information certain time period user, microprocessor judges voluntarily and cuts out data feedbacks filtering module (103), and begins to search the information writing position and make corresponding processing.Take place as serious situation such as occurring closing, current monitoring control module (104) system directly cuts off the power supply of data being fed back filtering modules (103), thoroughly breaks off the information interaction of terminal handler and storer, prevents and treats the data unofficial biography.
Need to prove that under the situation of not conflicting, the embodiment among the application and the feature among the embodiment be combination in any mutually.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
