CN1905564A - Method for user to dynamically change and filter rule - Google Patents

Abstract

The invention discloses a method for a user to dynamically modify filtering rules, comprising the steps of: if finding contents not according with the filtering rules, a content filtering server sends prompt options for regulating the filtering rules to a client end; a client-end user selects according to the prompt option and the client end sends the user selected options to the content filtering server; the content filtering server regulates the filtering rules according to the user selected options. Thus, the content filtering service can be subscribed by the user, or others. On the condition that the user and the subscriber are the same main body, if need be, the user can dynamically modify all or some of the content filtering rules when accessing contents.

Description

The user dynamically changes the implementation method of filtering rule

Technical field

The present invention relates to the Web content filtering technique, particularly a kind of user dynamically changes the implementation method of filtering rule.

Background technology

Along with networks development, a series of unhealthy and client had the content of threat, for example pornographic, violence, virus etc. are also following, therefore need a kind of information filtering technology to stop the infringement of these threats.

Present information filtering technology is mainly towards group user and the user of colony, for example company or family, by giving employee's subscribed content filtering services by company, be used for preventing visiting inoperative related web site and data during the employee is on duty, or give minor children's subscribed content filtering services by father and mother, be used for preventing that children are initiatively or passive reception some non-health and fitness site or data.

Fig. 1 shows a kind of existing communication network schematic diagram based on CBCS (Categorization-based Contebt Screening filters based on classified content) filtering rule.Comprise: portable terminal 1, wave point (air interface) 2, SGSN (Serving GPRS Supporting Node, GPRS service support node) 3 GGSN (Gateway GPRS Supporting Node,, Gateway GPRS Support Node) 4, SS7 network 5, SMSC (SMS Center, sms center) 6 and CBCS server 7, WAP gateway 8, Push Proxy Gateway 9 and MMSC (MMS Center, MMS center) 10 etc., can connect by wireless or wireline communication network between the various piece.CBCS service subscription person has subscribed to the rule of information filtering from CBCS server 7 theres of information filtering provider for portable terminal 1, user 1 is when the content of visit all-network end MMSC then, these contents all can be carried out information filtering through the CBCS server 7 of information filtering provider, are transferred to portable terminal 1 via various piece on the network again through the content after filtering.If these contents are the non-subscriber's subscription rules that meets, then the user visits or received content will be blocked, and the user receives an alarm information simultaneously.

Fig. 2 shows a kind of structural representation of existing C BCS server.As shown in the figure, CBCS server 20 and CBCS client 11 are connected by communication network, and CBCS client 11 is generally portable terminal, can start the service of CBCS server 20 by for example CBCS function allocating module or program etc.CBCS server 20 can comprise message processing unit 201, main control unit 202, virus base 203, classifying content and content classification rule 204, public content filtering rule 205, User Defined information filtering rule 206, virus scan unit 207, content recognition and identify unit 208, classifying content filter element 209 is subscribed to and user policy administrative unit 210 and information recording unit 211.

Particularly, message processing unit 201 comprises two parts: message sink and resolution unit and message sending unit.Client 11 will wish that the request that sends is packaged as SOAP (Simple Object AccessProtocol, simple object enters agreement) message format, connects with CBCS server 20 then.Message sink and resolution unit receive the soap message that client 11 is sent, message parse unit resolves SOAP packet format, and route messages to main control unit 202.

Subsequently, main control unit 202 receives message sink and resolves the message that unit forwards is come, information according to 11 requested service contents of user side in this message, obtain content corresponding, and according to these content scheduling virus scan unit 203, content recognition and identify unit 204, classifying content filter element 205, subscribe to and user policy administrative unit 206, content is handled accordingly.Obtain final result and send to message sending unit, message sending unit is carried out XML (ExtensibleMarkup Language) encapsulation with result then, and the result is returned to client 11.

Virus base 203, all " the appearance feature " of record computer virus is so that find that in time strangle them, only in this way, antivirus applet just can be distinguished Virus in general procedure, so the data in the virus base are also referred to as " virus signature ".Virus base 203 needs to upgrade often, could protect custom system not encroached on by up-to-date virus so as far as possible.

Classifying content and content classification rule 204 are used for the content to Network Transmission, as voice, literal, picture, video, Streaming Media etc., according to the feature of these contents, resolve classification; And,, carry out classification according to different ranks according to law or the standard or the guideline of concerned countries to the content of each class.

Public content filtering rule 205 comprises state compulsion rule and operator/service provider's rule.Wherein, the purpose of state compulsion rule is in order to protect the stable of nation's security and society, to relating to the violation state's laws, and exists the content blocking of hidden danger to propagate on network to national security and social stability; Operator/service provider's rule is the rule that Mobile Network Operator or mobile service provider set, as prevents that certain customers from touching inappropriate content etc.

User Defined information filtering rule 206 on the one hand be the rule of user according to the prevention partial content of personal like's setting, does not need to receive the rule of any picture etc. as the own setting of user; Be the rule that other people set for the user on the other hand, as the head of a family for the filtering rule of child's setting etc.

In addition, virus scan unit 207, based on the virus signature coupling, the content of the scanning file that the user asked.Specifically, viral uniqueness sign is discerned, virus of carrying in the cognitive content and virus killing by the scanning content that the user asked in virus scan unit 207.

Content recognition and identify unit 208, the effect with content recognition and sign two aspects.On the one hand,, the content that the user asked is classified according to classifying content and content classification rule 204, and according to the feature of these contents, the different brackets of identification content; On the other hand, according to the result of classifying content and classification, adopt the method for semantic description that content is identified, all give content corresponding to each content identified and describe, i.e. the description of the classification of content and classification is as the sign of content.Describe by this, can identify the classification and the corresponding grade of content very easily.

Classifying content filter element 209, two class filtering rule storehouses according to the classifying content of above setting and content classification rule 204 and public content filtering rule 205, in conjunction with user configuration information, control content identification and identify unit 208 are handled the classification of the content that obtains and the description of classification, and inappropriate content is filtered.

Subscribe to and user policy administrative unit 210, be used for the subscription of subscription, classifying content and information filtering business of leading subscriber Scan for Viruses business and the setting of the self-defined filtering rule of leading subscriber.

In addition, information recording unit 211 is used to write down the result of each processing unit processes, and the employed rule of content of recording processing user request and result that should rule.The data that these information records can be used as statistical analysis also can provide metering data for charge system (as rule-based charging).

Fig. 3 shows a kind of filtering process of existing CBCS content filtering system.CBCS is based on the service of subscription, and the service subscription person can be the user, can not be the user also.For example, can be this artificial own virus scan function of subscribing to of user, perhaps also can be father and mother are that child subscribes to the information filtering service that violence etc. endangers child's health.As shown in the figure, this filtering process comprises:

Step 301, CBCS client 11 is initiated the content requests services by CBCS server 20 to content supplier (ContentProvider) 30, as browsing page etc.;

Step 302, the content of 20 pairs of requests of CBCS server, for example web page address filters, and passes through if filter, and then carry out step 303, does not pass through if filter, and then carry out step 306, directly the result is returned to client 10;

Step 303, CBCS server 20 is initiated request according to the content requests of client 11 to content supplier 30;

Step 304, content supplier 30 sends content to CBCS server 20;

Step 305, the content that 20 pairs of content suppliers 30 of CBCS server return is filtered;

Step 306 returns to client 10 by CBCS server 20 with filter result, and this filter result comprises by content of filtering and the locking reason by the content of filtering.

Therefore, as can be seen, in the prior art, the user haves no right to change the information filtering rule that the subscriber orders.That is to say, be under the situation of same body user and subscriber, if the user need change the information filtering rule dynamically in access to content, can't realize.

Summary of the invention

For addressing the above problem, the object of the present invention is to provide a kind of user dynamically to change the implementation method of filtering rule, realize the dynamic change of user to the configuration of content filtering rule.

In order to address the above problem, the invention provides the implementation method that a kind of user dynamically changes filtering rule, may further comprise the steps:

If A. content filter server finds to have the content that does not meet filtering rule, then send the prompt options that is used to adjust filtering rule to client;

B. the user of client selects according to prompt options, and client sends to content filter server with user's selection;

C. content filter server is adjusted filtering rule according to user's selection.

This method also comprises:

D. content filter server filters, changes allocation list again according to adjusted filtering rule, and the content after will filtering again sends to client.

The described prompt options of this method comprise interim permission, permanent allow or do not allow blocked in perhaps a certain filtering rule; And if the prompt options that the user selects is interim permission, then step D lets pass the content that is filtered and sends to client; If permanent the permission, then step D lets pass to the content that is filtered, and revises corresponding allocation list according to user's option, and preserves; If do not allow, undo.

The described steps A of this method further comprises:

A1. content filter server encapsulates filtering result;

A2. insert described prompt options in the message that after encapsulation, obtains, message is sent to client.

Comprise the user's allocation list that is used to preserve user right in the described content filter server of this method, and this allocation list is corresponding one by one with user's sign, described method was carried out following steps before steps A 2:

Content filter server reads corresponding user's allocation list according to user's sign;

Judge according to described user's allocation list whether this user has the authority of change configuration, if not, then content filter server is given client with filter result with by the content feed of filtering, if, execution in step A2.

The described filtering rule of this method is based on the classified content filtering rule, and described content filter server is based on the classified content filtering server, and described client is to filter client based on classified content.

From above as can be seen, user provided by the invention dynamically changes the implementation method of filtering rule, CBCS service subscription person can be the user, also can be other subscribers outside the user, user and subscriber is under the situation of same body, if desired, the user can change whole or a certain information filtering rule dynamically in access to content.

Embodiment

Describe embodiments of the invention with reference to the accompanying drawings in detail.

Fig. 4 shows the signaling process figure that dynamically changes the CBCS layoutprocedure according to the user of the embodiment of the invention.

As shown in the figure, when CBCS server 20 sends to client 11 with filter result, because existing not meet, user's request or the content of being asked filter require part or all of, therefore, in step 401, filter result that CBCS server 20 returns to client 11 be set be one at not meeting the prompt options of filtering the content part that requires, as interim permission, the permanent permission or not etc.; In step 402, the user of client 11 selects according to prompt options, and client 11 sends to CBCS server 20 with user's selection, then in step 403, CBCS server 20 is adjusted filtering rule according to user's selection, subsequently, and in step 404, the CBCS server filters, changes allocation list again according to adjusted filtering rule, and the content after will filtering again sends to client.

The change filtering rule of above-mentioned steps 403 is based on that the allocation list file of change CBCS system realizes.Table 1 shows a kind of exemplary CBCS allocation list file.

Whether allow the user to on-the-fly modify allocation list	Allow
			The text filtering rank	3 grades
The image filtering rank	3 grades
			Virus scan	Support

Table 1

Wherein, as an example, show several allocation list file options.CBCS server 20 can realize controlling the authority that the user dynamically changes the CBCS configuration file by revising " whether allowing the user to on-the-fly modify allocation list " option for allowing or not allowing.Certainly, by being provided with and revising other options of allocation list file, for supporting or do not support etc., can realize the control of 20 pairs of content filtering rules of CBCS server etc. such as the virus scan option.In addition, such as text filtering rank or image filtering rank, can be set to 3 grades or other etc., the high more filtering rule of grade is strict more.

According to the present invention, the allocation list file be with user ID (ID) one to one.User's IP address, user name etc. can be as identification user's ID.Thus, can form user's configuration database in the CBCS server 20, store a plurality of and user ID allocation list file one to one.

The user that Fig. 5 shows Fig. 4 dynamically changes the detailed step of CBCS layoutprocedure.

The CBCS server carries out in the filter process user's the request or the content of user's request, if find not meet the content of filtering rule, then enters the process that user of the present invention dynamically changes the CBCS configuration.Promptly executing abovementioned steps 302 or 305, obtain whole filter result after; Perhaps also can be in carrying out abovementioned steps 302 or 305 processes, whenever finding that the content that does not meet filtering rule just enters following flow process.Referring to shown in Figure 5, concrete steps are as follows:

Step 501, the CBCS server encapsulates current filtering result, and this filter result comprises by content of filtering and the locking reason by the content of filtering;

Step 502, the CBCS server reads corresponding user's allocation list according to user's ID;

Step 503 according to the information of user's allocation list record of reading, judges whether this user has the authority of change configuration, if this user does not change the authority of configuration, then enter step 504, perhaps, if this user has the authority of change configuration, then execution in step 505;

Step 504, the CBCS server directly feeds back to client with filter result, comprising by the content of filtering and and at an alarm prompt of the locking reason by filtering content not;

Step 505, insert prompt options in the message that after encapsulation, obtains, select for the user, such as, can be by inserting popup menu in the page of browsing the user, contents of menus is filter result and prompt options, perhaps insert note, content is filter result and the code selected by the user, and this code is in order to replying to server, after the encapsulation, by HTTP or SMS agreement message is sent to client, wherein prompt options can be interim the permission, the permanent permission, perhaps do not allow blocked content, promptly, wherein can be provided with and not allow for default option not by content part or a certain filtering rule of filtration;

Step 506, after client is received the message that server returns, message is resolved, and show the user, the user reads the result and makes one's options, select interim permission such as the user, then press the interim permission button or the answer short message 1 of pop-up window, set in the option code that server provides herein, replying 1 be interim permission, replying 2 is permanent the permission, replys 3 for not allowing;

Step 507, client feeds back to server with the option that the user selects;

Step 508, server is handled the option of client, that is, if interim the permission then let pass the content that is filtered; If permanent the permission then let pass to the content that is filtered, and read this user's allocation list from user's configuration database,, and preserve according to user's the feedback option allocation list of making amendment.

Afterwards, step finishes.

The application of CBCS of the present invention is below described for example.Use mobile phone to browse with the user and be example.

Step 1, the user starts mobile phone browser, the network address that input is desired to browse in browser, for example: www.xxx.com.cn;

Step 2, browser is initiated web-page requests through the CBCS server to the www.xxx.com.cn website;

Step 3, the CBCS server filters chained address www.xxx.com.cn, passes through if filter, and request is transmitted to the xxx website;

Step 4, xxx handles request the website, and web site contents is fed back to the user via the CBCS server;

Step 5, CBCS judges whether this user has subscribed to the CBCS business, if not subscribe to then filter with public rule, if subscribed to then with the rule-based filtering of subscribing to, if all pass through, then all the elements are transmitted to the user, if a certain content, for example photo1 does not pass through, and then the CBCS server judges according to the allocation list of subscribing to whether this user supports dynamically change configuration authority, if do not support, then card falls the content of photo1, and other guide is transmitted to the user, and an alarm information is provided simultaneously, if support dynamically change allocation list, then the CBCS server produces the alarm menu have selection function, wherein this menu be presented at the user browse homepage above, under situation about the alarm menu not being made one's options, can't read homepage, then other guide and this menu be sent to the user together;

Step 6, the user selects menu, if the user selects interim permission, then CBCS is handed down to the user with blocked content photo1.jpg, if the user selects the permanent filtration grade that allows and revise the type file, then CBCS is handed down to the user with blocked content photo1.jpg, and read this user's allocation list, adjust the filtration grade of the file of the type according to customer requirements, and preserve allocation list, such as: current allocation list image filtering grade is 3, the grade of locked content photo1.jpg is 2 grades, if the user selects permanent permission, then change the image filtering rank in the table 1 into 2 grades by 3 grades, and locked content is sent to the user; If the user selects interim permission, then locked content is issued the user but do not revise allocation list; If select not allow, then CBCS does not issue photo1.jpg.

Be that example is illustrated preferred embodiment of the present invention with the CBCS filtering rule above, the present invention also can be applicable to other filtering rule in addition.

It is to be appreciated that those skilled in the art that under the prerequisite that does not break away from the spirit or scope of the present invention, the present invention also has various improvement and variation.Therefore, various improvement of the present invention and variation are included in the scope of the present invention that is limited by appended claims and equivalent thereof.
