In the related art, with the continuous development of information technology, a large part of daily communication and communication of people is transferred to network information communication, but various sensitive information which endangers public safety such as violence, politics, horror, pornography and the like may be involved in the communication process of network information, and the sensitive information must be removed in time to ensure network civilization and public safety.
At present, the removing methods aiming at the sensitive information mainly comprise the following two methods: the first mode is that sensitive information existing in network information is screened through manual review, and although the method is high in accuracy, manual screening is long in time consumption and low in efficiency; the second method is that after the network information is sent to each operator server, each operator screens the received network information in its own server to shield the sensitive information, but the operators corresponding to different network communication software or network information platforms are different, and the servers are also distributed across the country, so that they cannot be processed uniformly, and the efficiency is low.
Therefore, the screening efficiency for sensitive information is low at present.
In view of the above problems, the embodiments of the present disclosure provide a network traffic information processing method, which directly performs screening of sensitive information on received network traffic in a user function system, and directly performs screening and filtering on the sensitive information from a source, so that it can effectively avoid that the network traffic information including the sensitive information further flows into a large network and is difficult to control, thereby greatly improving the efficiency of screening the sensitive information; meanwhile, the network traffic information processing method provided by the embodiment of the disclosure can not only shield the network traffic information containing the sensitive information, but also shield the user corresponding to the network traffic information containing the sensitive information, so as to prevent the user from sending the network traffic information containing the sensitive information again, or further package or convert the sensitive information and then continue sending the sensitive information, thereby effectively improving the processing security and the processing reliability for the sensitive information.
The following briefly introduces an application environment of the network information processing method provided by the embodiment of the present disclosure:
referring to fig. 1, an embodiment of the present disclosure is applied to a communication safety control system 10, where the communication safety control system 10 at least includes: a plurality of user terminals 101 and a control terminal 102. The number of the user terminals 101 is multiple, and the user terminals are respectively used for corresponding users to send network information or receive network information; the control terminal 102 refers to a management terminal of a communication carrier. It should be noted that the control terminal 102 is configured with a User Plane Function (UPF) system, which is one of the 5G core network systems, and the gsnodeb and the like are logically interconnected through an NG3 interface to implement packet routing and forwarding, packet inspection, User Plane partial policy implementation, and the like. The structure of the user plane function system comprises: the system comprises an information acquisition interface, a strategy configuration module, an information processing module, a packet routing and forwarding module and the like. The information acquisition interface is used for acquiring network flow information from external equipment; the strategy configuration module is open to the outside and is used for the staff to configure the strategies of the internal information, the modules and the like; the information processing module is used for filtering, shielding, converting and the like on the received information or the generated information; the packet routing and forwarding module is used for performing packet routing on the received information or the information processed by the information processing module, or forwarding the received information or the information to other equipment.
The following description will take the control terminal 102 as an execution main body, apply the network information processing method to the control terminal 102, and perform security control on the network traffic information transmitted by the user terminal 101 as an example. Referring to fig. 2, a network information processing method provided in the embodiment of the present disclosure includes the following steps 201 to 204:
The network traffic information refers to information used for communication and communication sent by a user through a user terminal, for example, instant information such as QQ, WeChat, and short message, or platform communication information such as a bar, a forum, and a microblog, and this embodiment is not particularly limited. One user terminal can send one or more pieces of network flow information corresponding to one user; for example, a computer may log in multiple QQ accounts at the same time, and different QQ accounts send respective QQ messages, or a mobile phone may insert multiple SIM cards at the same time, and different accounts corresponding to different SIM cards send respective network traffic information such as short messages, flyings, and WeChats.
The user sends the network flow information to the control terminal through the user terminal, and the control terminal obtains the network flow information sent by the user terminal in real time or according to a certain period through an information obtaining interface in an internally configured user plane function system.
After the control terminal acquires the network traffic information from the information acquisition interface, semantic matching can be performed in the following ways:
in the first mode, the control terminal inputs the network traffic information into a semantic recognition model obtained by pre-training, and then preset sensitive information in the network traffic information can be directly recognized and obtained through the semantic recognition model; the semantic recognition model is obtained based on a large amount of preset sensitive information training; in the second mode, the control terminal searches the network traffic information one by one based on the preset sensitive information to determine whether the network traffic information contains the preset sensitive information; and in the third mode, word segmentation processing is carried out on the network traffic information, and then the matching degree of each word segmentation and preset sensitive information is judged respectively.
And 203, the control terminal judges whether the network flow information contains preset sensitive information according to the matching result.
And the control terminal determines whether the network flow information contains preset sensitive information according to the matching result. For example:
aiming at the first mode, the semantic recognition model directly outputs a result of whether the result contains preset sensitive information, the control terminal directly obtains a judgment result through the semantic recognition model without further judgment, the recognition effect is better, and the efficiency is higher;
for the second manner, if the characteristic frequency of any one piece of preset sensitive information appearing in the network traffic information is not 0, it is determined that the network traffic information contains the preset sensitive information; if the characteristic frequency of all the preset sensitive information in the network traffic information is 0, determining that the network traffic information does not contain the preset sensitive information; the retrieval mode is simple and the accuracy is high.
For the third method, if the matching degree of any word segmentation and the preset sensitive information is greater than a preset threshold, for example, 70%, 80%, and the like, it is determined that the network traffic information includes the preset sensitive information; and if the matching degree of all the participles and the preset sensitive information is smaller than or equal to a preset threshold value, determining that the network traffic information does not contain the preset sensitive information. Through the word segmentation mode, whether the preset sensitive information is contained in the network flow information or not can be determined efficiently, the sensitive information in the network information can be accurately positioned, and the identification effect of the sensitive information is better.
And 204, if the network traffic information contains preset sensitive information, the control terminal shields the network traffic information and shields users corresponding to the network traffic information.
Once the control terminal finds that certain network traffic information contains preset sensitive information, the control terminal shields the network traffic information. The shielding in the embodiment of the present disclosure means that the user plane function system prevents the network traffic information from being further issued to the routing or forwarding module, so as to prevent the network traffic information including the sensitive information from entering the large network. For example, Network traffic information may be prevented from being forwarded to a Destination Network (DN). Meanwhile, the control device further shields the user corresponding to the network traffic information while shielding the network traffic information so as to prevent the user from continuously sending other sensitive information or packaging or converting the sensitive information and sending the sensitive information again.
The network flow information processing method provided by the embodiment of the disclosure directly screens the received network flow at the user function system, and directly screens and filters the sensitive information from the source, so that the network flow information containing the sensitive information can be effectively prevented from further flowing into a large network and being difficult to control, and the efficiency of screening and detecting the sensitive information is greatly improved; meanwhile, the network traffic information processing method provided by the embodiment of the disclosure can not only shield the network traffic information containing the sensitive information, but also shield the user corresponding to the network traffic information containing the sensitive information, so as to prevent the user from sending the network traffic information containing the sensitive information again, or further package or convert the sensitive information and then continue sending the sensitive information, thereby effectively improving the processing security and the processing reliability for the sensitive information.
Referring to fig. 3, in an optional embodiment of the present disclosure, the information obtaining interface is configured with a security control switch, and the step 201, where the control terminal obtains the network traffic information sent by the user terminal based on the information obtaining interface, includes the following steps 301 to 302:
The control terminal may detect whether the user terminal generates the network traffic information in the following two ways: in the first mode, each user terminal monitors the state of the network traffic information thereof in real time, updates the state of the network traffic information thereof immediately once the new network traffic information is added, and sends a state updating instruction to the control terminal, the control terminal determines that the current user terminal has the newly generated network traffic information once receiving the state updating instruction, and determines that the user terminal does not have the newly generated network traffic information currently if not receiving the state updating instruction. In the second mode, a terminal information acquisition interface configuration information detection program is controlled, and whether network flow information is accessed is detected in real time based on the information detection program; the information detection program is used for detecting whether network flow is generated at present, and if the network flow access is detected, the user terminal is determined to generate network flow information; and if the network flow access is not detected, determining that the user terminal does not generate the network flow information.
And step 302, if the user terminal generates the network flow information, the control terminal opens the safety control switch and acquires the network flow information sent by the user terminal based on the information acquisition interface.
Once the control terminal determines that the user terminal generates the network traffic information through step 301, the control terminal turns on the security control switch configured in the information acquisition interface, and acquires the network traffic information sent by the user terminal through the information acquisition interface.
In the embodiment of the disclosure, when the user terminal generates the network traffic information, the security control switch is turned on to receive the network traffic information sent by the user terminal, and in other cases, the security control development is turned off to avoid that the user plane functional system receives too much other useless information to affect the information processing efficiency thereof, so as to further ensure the processing efficiency of the network traffic information processing method provided by the embodiment of the disclosure.
In an optional embodiment, a worker may set a switching period for the safety control switch according to historical data or historical experience, and configure the safety control switch to be in a closed state in a preset period, so that the worker can conveniently modify and test internal information; and keeping the safety control in an open state in other time intervals outside the preset period so as to acquire the network flow information sent by the user terminal in real time through the information acquisition interface. Of course, in another alternative embodiment, the state control of the safety control switch can be opened to the outside, and the control can be flexibly controlled by the staff.
Referring to fig. 4, in an optional embodiment of the present disclosure, the preset sensitive information is a preset sensitive vocabulary, and the step 202 of semantically matching the network traffic information and the preset sensitive information by the control terminal to obtain a matching result includes the following steps 401 to 403:
The form of the network flow information may include characters, pictures, videos, audios and the like, and the control terminal performs format conversion after receiving the network flow information and converts the network flow information into a text form so as to facilitate processing. If the network traffic information is a picture, extracting the character information in the picture through a pre-stored character recognition model to form text information to be processed; if the network flow information is in a video or audio form, the voice information in the network flow information is converted into text information through video or audio conversion software.
And step 402, the control terminal performs vocabulary segmentation processing on the text information to be processed based on the text word segmentation model to obtain a plurality of information vocabularies.
After the control terminal obtains the text information to be processed through step 401, the control terminal performs vocabulary segmentation processing on the text information to be processed based on the text vocabulary segmentation model stored in advance, so that a plurality of information vocabularies are obtained. The text word segmentation model can be a word model such as a hidden Markov model, a conditional random field model and the like, and the embodiment is not particularly limited, can be specifically selected according to actual conditions, and only needs to realize the function of segmenting text information to be processed into a plurality of information words.
And step 403, the control terminal respectively determines the matching degree of each information vocabulary and a preset sensitive vocabulary based on the semantic matching model to obtain a matching result.
The word segmentation is performed on the network traffic information, and then the matching degree between each information vocabulary and the preset sensitive vocabulary is determined in the third manner in the step 202. The matching degree between each information word and the preset sensitive word is calculated one by one based on a semantic matching model, wherein the semantic matching model can be an LSTM matching model, an MV-DSSM [3] model, an ESIM [4] model and the like, the embodiment is not limited at all, and can be specifically selected according to actual conditions, and only the matching degree between each information word and the preset sensitive word needs to be determined.
According to the embodiment of the disclosure, the network flow information is preprocessed into the text information to be processed, so that subsequent unified processing can be facilitated, and the information processing efficiency can be effectively improved; meanwhile, the text information to be processed is divided into a plurality of information vocabularies based on the text word segmentation model, and finally, the matching degree of each information vocabulary and the preset sensitive vocabulary is determined respectively based on the semantic matching model, so that the matching result is accurate, and the matching accuracy is higher. Therefore, the embodiment of the present disclosure improves matching efficiency from multiple dimensions on the premise of improving matching accuracy, and further improves network information processing efficiency for the embodiment of the present disclosure on the premise of ensuring information processing accuracy.
Referring to fig. 5, in an optional embodiment of the present disclosure, the step 203 of determining, by the control terminal, whether the network traffic information includes preset sensitive information according to the matching result includes the following steps 501 to 502:
As shown in step 203, for example, the preset threshold is 80%, and if the matching degrees of all the information vocabularies and the preset sensitive information are less than or equal to 80%, it is determined that the network traffic information does not include the preset sensitive information. Of course, the specific value of the preset threshold is not specifically limited in this embodiment, and may be specifically set according to the actual situation.
As in step 501, if the matching degree between any information participle and the preset sensitive information is greater than 80%, it is determined that the network traffic information includes the preset sensitive information.
According to the method and the device for identifying the network traffic information, word segmentation is firstly carried out, then the relative size between the matching degree of each information word segmentation and the preset sensitive information and the preset threshold value is judged to determine whether the network traffic information contains the preset sensitive information, through the word segmentation mode, whether the network traffic information contains the preset sensitive information can be efficiently determined, the sensitive information in the network information can be accurately positioned, and the identification effect of the sensitive information is better.
Referring to fig. 6, in an optional embodiment of the present disclosure, the number of the preset sensitive words is multiple, the preset sensitive information is the preset sensitive words, and the step 202, where the control terminal performs semantic matching on the network traffic information and the preset sensitive information to obtain a matching result, includes the following steps 601 to 603:
As shown in step 401, the form of the network traffic information may include characters, pictures, videos, audios, and the like, and the control terminal performs format conversion after receiving the network traffic information, and converts the format into a text form for convenient processing. If the network traffic information is a picture, extracting the character information in the picture through a pre-stored character recognition model to form text information to be processed; if the network flow information is in a video or audio form, the voice information in the network flow information is converted into text information through video or audio conversion software.
As shown in step 402, after the control terminal obtains the text information to be processed, the control terminal performs vocabulary segmentation processing on the text information to be processed based on the text vocabulary segmentation model stored in advance, so as to obtain a plurality of information vocabularies. The text word segmentation model can be a word model such as a hidden Markov model, a conditional random field model and the like, and the embodiment is not particularly limited, can be specifically selected according to actual conditions, and only needs to realize the function of segmenting text information to be processed into a plurality of information words. For example, the text to be processed is "i just see that there is a section in" this statement "that someone does b things at a", and the information of the text to be processed is input into the text word segmentation model, so that the 14 information words "i/just/see/this day/say/medium/have a section/yes/someone/at/a/do/b things" can be obtained.
After the control terminal obtains the plurality of information words, the control terminal searches the plurality of information words one by one based on the preset sensitive words so as to determine the characteristic frequency of each word appearing in the plurality of information words. For example, the preset sensitive words include "b things" and "c things", and for the 14 information words "i/just/see/this day/say/in/have one/fragment/be/someone/at/a/do/b things" in the above step 602, the frequency of occurrence of "b things" in the 14 information words is first found to be 1; then, the feature frequency of 'things c' in the 14 information words is searched for to be 0.
The method comprises the steps of firstly converting network flow information into text information to be processed, then carrying out vocabulary segmentation processing on the text information to be processed based on a text word segmentation model to obtain a plurality of information vocabularies, finally respectively determining the characteristic frequency of each preset sensitive vocabulary in the plurality of information vocabularies, and determining whether the network flow information contains the preset sensitive information based on the characteristic frequency. When the preset sensitive information is less, the method can greatly improve the searching speed of the sensitive information, is beneficial to carrying out statistical analysis on the occurrence weight of each sensitive information, can improve the processing efficiency of the network flow information at this time, and is also beneficial to carrying out information analysis processing at the later stage.
Referring to fig. 7, in an optional embodiment of the present disclosure, the step 203 of determining, by the control terminal, whether the network traffic information includes preset sensitive information according to the matching result includes the following steps 701 to 702:
For example, if the number of the preset sensitive words is 5, and the frequency of occurrence of the 5 words is 0, it is determined that the network traffic information does not include the preset sensitive information, and the information can be normally processed, for example, the information is issued or forwarded by the routing forwarding module.
For example, in step 603, if the characteristic frequency of the sensitive word "things c" is 0, but the characteristic frequency of "things b" is 1, it is determined that the piece of network traffic information still includes the preset sensitive information, and the piece of network traffic information needs to be processed, such as further screening, masking or blocking.
The embodiment of the disclosure determines whether the network traffic information contains the preset sensitive information based on whether the characteristic frequencies are all 0, and when the preset sensitive information is less, the searching speed of the sensitive information and the reliability of the determination of the sensitive information can be greatly improved.
Referring to fig. 8, in an optional embodiment of the present disclosure, the network traffic information includes a user identity, and the step 204 and the control terminal shield the user corresponding to the network traffic information, which includes the following steps 801 to 802:
The user data management system stores the signing information of different users and the authority configuration files of the users, and the authority configuration files correspond to the user identities one by one. The User Data management system may be a User Data Request (UDR) system, the network traffic information received by the control terminal includes a User identity, and the User identity may be an ID, an identity account, or the like. The control terminal queries in the user management system based on the user identity, and obtains a target authority configuration file corresponding to the user identity based on the one-to-one correspondence relationship between the user identity and the authority configuration file, wherein the authority configuration file refers to functional items executable by the user, such as sending messages, receiving messages and the like.
And step 802, the control terminal configures the message sending authority in the target authority configuration file into a forbidden message sending state.
Once the control terminal determines that the network traffic information contains the preset sensitive information, the control terminal finds out a target permission configuration file of a user corresponding to the network traffic information based on step 801, and modifies permission of sending a message in the target permission configuration file into prohibition so as to prevent the user from continuously sending a message related to the sensitive information.
The method and the device for prohibiting the message sending authority of the user directly use the target authority configuration file in the user data management system to prohibit the message sending authority of the user, not only shields the network flow information containing sensitive information, but also prohibits the message sending authority of the corresponding user, and can effectively prevent the user from further sending some bad information, thereby improving the processing effect of the sensitive information and ensuring the safety and reliability of network communication.
