Five, embodiment:
Embodiment one: referring to Fig. 1, Fig. 3, network pornography image and flame detect multifunctional management system, contain server subsystem and client computer subsystem, both realize communication and data interaction by communication module, server subsystem contains the detection procedure administration module, image detection is surveyed API, PCI driver module and video processing board-card, video processing board-card is installed on the server computer, the detection procedure administration module is in order to finish and the communicating by letter of client computer, server subsystem starts an image detection thread and client communication, finish communicating by letter of server and client computer, call video processing board-card simultaneously, image is detected and return testing result; Described server subsystem also contains other worker thread, comprises the data analysis service, in order to the analytical system daily record, carries out the record and the analysis of bad network address, handles bad url list; Automatically whether update service is made regular check on version and is upgraded, and upgrades from the internet automatically; User application interface, for the user provides the URL that enhances trust, bad URL and display system daily record.The client computer subsystem contains the data filter interface, separates protocol module, data detection module, update module, server communication module automatically, and data filter interface wherein is responsible for obtaining website data and loopback interface; Separate protocol module, extract http protocol and handle; Data detection module contains credible URL detection, bad URL detection, keyword detection and image detection; Automatically update module is upgraded application program and data automatically from the internet; The server communication module is realized communication and data interaction between client computer and server.
Referring to Fig. 2: multifunctional management system server subsystem workflow block diagram, server at first starts the connection request that a monitor process is monitored client computer, and after receiving the connection request of client computer, start the image detection thread, detect thread by imperative structures and clients exchange information, call video processing board-card simultaneously network image is detected, and pass result back client computer.The processing procedure more complicated of image detection process reality, if for example judge that request URL is bad URL, then server no longer detects the order of just directly returning " filtration ".In the image detection process, the image detection of image detection card is serial, but the image detection request walks abreast, in other words a plurality of image detection requests can take place in a period of time, therefore need by a scheduling thread image detection request to be delivered in the test card according to the order of " detecting earlier first ".The image detection process also can write journal file to the result who detects, and the data of analysis are provided for later system manager.
Fig. 4 is that network pornography image and flame detect multifunctional management system data filter interface composition schematic diagram, the Windows socket application programming interface for client applications access network services of data filter interface for providing by Winsock2, comprise the Winsock ISP interface SPI and the ws2_32.dll that are realized by transmission ISP and name resolution ISP, its filtration pattern is: the HOOK interface (core DLL) of installing or unload the SPI open standard; Data processing core (HOOKDLL); Image detection interface (network communication interface), the mutually mutual communication of this three.
The interface function that SPI is opened to standard inserts one deck in the middle of the ISP, thereby realizes SPIHOOK.SPI has an allocation list, the order of in store loading and other attribute information, and this table just is kept in the registration table, and operating system can load the SPI module according to this table.By revising this table, allow our SPI module of system loads, our SPI module reloads system then, and connection request is forwarded to system, finishes the HOOK of SPI.
Utilize the sSpiPathName in the self-defining SPIDLL Program path replacement registration table, and the sSpiPathName of saved system, after finishing such operation, system will use self-defined SPIDLL when loading SPI, utilizes the SPIDLL of the system path loading system of preserving to finish forwarding then.Before using SOCKET, must call the WSPStarup of SPI, 30 SOCKET service function pointers that obtain SPI from this function provide SOCKET communication service then.
Last parameter L pProcTable is used for returning the pointer of 30 SPI service functions.Derive the WSPStartup function so need write a DLL, and be installed to system as the ISP, when the self-defined DLL of system loads, the corresponding SPIDLL of loading system uses LoadLibrary loading system DLL then.Self-defined DLL uses GetProcAddress to obtain the WSPStartup function pointer of the DLL of system, can obtain 30 ISP's function pointers, and it is modified as own function address.
Referring to Fig. 6.Because the detection pornographic image is the application layer at server, when being unpacked back pie graph picture frame, a plurality of IP packets carry out, for TCP connects not chain rupture, adopt " storage is transmitted " method: filtration system is left complete data message earlier, issue client again, Web is made a start, and the filtration system debit that disguises oneself as is to real recipient's client computer originating party that disguises oneself as again.Because the filtration system connection processing is a plurality of complete message of a plurality of client computer, any one equipment does not all have this concatenation ability, and we will lose the message that some affect the general situation in the accurate Calculation time-out time for this reason, guarantee to connect not chain rupture.
Fig. 5 is a client computer subsystem image detection process workflow of the present invention.URL detects and the keyword detection is to detect the data in the IP bag, and therefore fairly simple: the image detection process is to detect complete image, generally is the combination that several IP wrap, so more complicated.SurGuard.d11 judges whether the HTTP head is the image request head after intercepting and sending data.If image then judges that according to User-Agent this packet is that browser sends or SurGuard.d11 sends, if the data that browser sends, then duplicate socket (sockaddr-in structure) and Send (Get data) data, start a new thread these data are sent to the purpose http server.
The purpose http server generally can return 2000K or 304Not Modified, and the former represents normal data, and the latter has represented to use the cache of IE.New thread receives the data of http server and is sent to the image detection server and detects, and handles browser Send data according to testing result, if then directly clearance of normal data, if bad view data is then with " GET " makes into "! ET " send.
The purpose of not blocking the Send data is to receive a normal http server response, and response data is replaced to predefined view data, and browser just can replace to bad image the image of setting like this.Http server receive "! ET " to be bound to reply 501 misrepresentation HTTP request imperfect in request, and at this moment that the response data of server is replaced to predefined view data is just passable for SurGuard.d11.
Embodiment two: referring to Fig. 1, present embodiment is substantially with embodiment one, and its difference is: present embodiment network pornography image and flame detect multifunctional management system, and the website is filtered and adopted absolute filtering policy.The function of information filtering product is to prevent flame on the Internet to teen-age harm, and is wherein particularly important to the filtration of pornographic image information.No matter be that domain name is filtered, the IP address filtering, or image filtering, what finally estimate filter effect is the integral filter ability of system.
Absolute filtering policy is to have increased the image statistics function on the basis that normal image is filtered, and promptly comprises rate by the pornographic image of adding up a webpage and judges that this website is the porn site, closes down this website then.What adopt at present is simple pornographic image counting, as long as a webpage is judged n (getting 5 at present) pornographic image, then directly closes down whole website.
After adopting absolute filtering policy, pornographic image interception rate reaches 99.38%, and website interception rate reaches 99.75%, and reaching high filter effect like this is cost to close down normal website, and this is very important for the teenager.In order to remedy this defective, system has adopted the method for classification setting, and the head of a family or adult can not be subjected to the restriction of this filtration like this.
Embodiment three: referring to Fig. 1, Fig. 2, present embodiment network pornography image and flame detect multifunctional management system, server subsystem contains other worker thread, other worker thread comprises the data analysis service, in order to the analytical system daily record, carry out the record and the analysis of bad network address, handle bad url list; Automatically whether update service is made regular check on version and is upgraded, and upgrades from the internet automatically; User application interface, for the user provides the URL that enhances trust, bad URL and display system daily record.
