Description

Technical Field

[0001] The invention belongs to the technical field of data security monitoring management and relates to an online intelligent data security monitoring and management system. Background Art

[0002] Media advertisements are generated during advertising activities and include comprehensive data such as the copy information carried by the advertising text, the visual element information displayed in the advertising screen, and the audio-visual content in the advertising video. The transmission of media advertisements is like building an information bridge. If this bridge is not secure, the data will be stolen or tampered with during transmission, which will lead to the outflow of sensitive information and infringe on the rights and interests of users. At the same time, if the media advertisement itself contains false, exaggerated, infringing or illegal content, even if it has not yet been released, it will inevitably lead to legal risks once it leaks out later. Therefore, media advertisements need to be monitored and managed.

[0003] At the existing technical level, for example, the Chinese invention patent with publication number CN104599157B discloses an LED advertising playback monitoring platform, whose technology focuses on advertising information storage, playback frequency calculation and business information display, but its technical solution has essential defects: 1. It completely ignores the security considerations of the media advertising transmission link, that is, it pays insufficient attention to the security of media advertising transmission, and cannot guarantee the transmission security and transmission integrity of media advertising, which leads to an increased risk of media advertising leakage.

[0004] At the existing technical level, for example, the Chinese invention patent with publication number CN118674463A discloses a joint police-civilian anti-fraud circulation platform, which monitors fraud information and false advertisements. However, its technical solution has essential defects: 2. It only monitors the "anti-fraud" single dimension of advertising content, and lacks attention to the core content security elements such as the violation and plagiarism detection of media advertising content, which cannot guarantee the security of media advertising content, and thus leads to the lack of legitimacy of media advertising content. Summary of the invention

[0005] In view of this, in order to solve the problems raised in the above background technology, a data security online intelligent monitoring and management system is now proposed.

[0006] The purpose of the present invention can be achieved through the following technical solutions: The present invention provides a data security online intelligent monitoring and management system, including: a data transmission analysis module, which is used to collect the transmission data information of the corresponding data packets of media advertisements when uploading, and perform coupling analysis to obtain the transmission security factor of the media advertisements.

[0007] The data transmission judgment module is used to compare and analyze the transmission safety factor with a set safety threshold to generate a transmission qualification judgment result.

[0008] The data content analysis module is used to analyze the video content information of the data packet when the transmission qualification judgment result is transmission qualification, including the advertisement type, each advertisement word, each advertisement picture, the number of key parameters and each key parameter value.

[0009] The data content confirmation module is used to perform multi-dimensional comparative analysis based on the video content information of the media advertisement to obtain the control instructions of the media advertisement.

[0010] The database is used to store the initial checksum before the transmission of the media advertisement, store the initial data length of each data block in the media advertisement, store the set of illegal words in the media advertisement, store the number of reference key parameters of each advertisement type, store each reference key parameter value of each advertisement type, and store each advertisement word of each historical media advertisement.

[0011] The data control feedback terminal is used to execute control instructions to complete advertising delivery or block advertising.

[0012] Compared with the prior art, the beneficial effects of the present invention are as follows: (1) The present invention collects multi-dimensional information of advertising data packets for coupled analysis, and constructs a comprehensive transmission security evaluation system including encryption qualification coefficient, integrity qualification coefficient and transmission stability qualification coefficient, which effectively solves the problem of single traditional advertising transmission security evaluation and ensures the confidentiality and stability of advertising data during transmission.

[0013] (2) The present invention analyzes the violation coefficient, deviation coefficient and plagiarism coefficient of the video content information of media advertisements, realizes a triple compliance review of the video, and generates control instructions, thereby increasing the attention paid to the violation and plagiarism of media advertisements, and ensuring the legality and originality of the advertising content from the source.

[0014] (3) The present invention ensures that media advertisements are not tampered with or damaged during transmission by adopting a three-level integrity verification mechanism of checksum bit-by-bit comparison, data block length consistency analysis, and position verification, thereby improving the transmission integrity and accuracy of media advertisements and improving the continuity of subsequent advertisement delivery.

[0015] (4) The present invention constructs a traffic change curve and introduces a transmission stability analysis model to monitor network fluctuations during advertisement transmission in real time, thereby effectively ensuring the continuity and reliability of advertisement delivery.

[0023] The data transmission analysis module is used to collect transmission data information of the data packets corresponding to the media advertisements when they are uploaded, and to perform coupling analysis to obtain the transmission safety factor of the media advertisements.

[0024] It should be added that the transmission data information includes the encryption protocol type, key length, checksum, hash value, data length of each data block, data location and traffic at each monitoring time point.

[0025] It should be added that the encryption protocol type and key length in media advertisements are obtained through analysis using network protocol analysis software.

[0026] It should be added that the media advertisement checksum is obtained through network packet capture tools. Its working principle is: network packet capture tools can capture the corresponding data packets of media advertisements. During the transmission process of media advertisements, the checksum is usually included in the header or tail of the data packet. These tools can capture the complete data packet containing media advertisements. When the media advertisements are transmitted through the network, after the packet capture tool captures these data packets, it directly obtains the checksum value by parsing the protocol format of the data packet.

[0027] It should be added that the media advertisement hash value is captured through network protocol analysis tools.

[0028] It should be added that the data length and data position of each data block in the media advertisement are captured by a network protocol analysis tool.

[0029] It should be added that the traffic of media advertisements at each monitoring time point is obtained through network traffic monitoring software, and its working principle is as follows: the network traffic monitoring software collects media advertisement traffic data by installing an agent program on the server or client device. For example, the traffic monitoring software installed on the advertising server can capture the media advertisement traffic sent from the server. The software will count the data packets passing through a specific network interface, calculate the size of each data packet, and sum them within the set monitoring time interval, thereby obtaining the traffic of media advertisements at each monitoring time point.

[0030] See also Figure 2 As shown, exemplarily, the coupling analysis includes: A1, matching and analyzing the encryption protocol type and key length in the transmission data information respectively to obtain the encryption qualification coefficient of the media advertisement.

[0031] Furthermore, the encryption protocol type and key length in the transmitted data information are matched and analyzed respectively, including: A1-1, matching and comparing the encryption protocol type with the encryption protocol type corresponding to each encryption protocol security score to obtain the encryption protocol security score of the media advertisement.

[0032] A1-2. The encryption algorithm security score of media advertisements can be obtained by analyzing the encryption protocol security score in the same way.

[0033] A1-3. Perform deviation analysis on the encryption protocol security score and encryption algorithm security score of media advertisements and their corresponding reference encryption protocol security score and encryption algorithm security score to obtain the encryption qualification coefficient of media advertisements, where the encryption qualification coefficient is calculated by the expression: Calculate the encryption qualification coefficient of media advertising , and The security scores of media advertising encryption protocols and encryption algorithms are respectively and They are the reference encryption protocol security score and encryption algorithm security score respectively.

[0034] It should be added that the referenced encryption protocol security score and encryption algorithm security score are both obtained by analyzing historical media advertisements in the same way as above and calculating the average.

[0035] It should be added that The degree of deviation between the ad encryption protocol score and the reference score, The degree of deviation between the ad encryption algorithm score and the reference score. The closer it is to 1, the smaller the deviation between the security score of the advertising encryption protocol and algorithm and the reference score is, and the more qualified the encryption security is. The lower it is, the greater the deviation is, and the more encryption security needs to be optimized.

[0036] A2. Compare and analyze the checksum, hash value, data length and data position of each data block in the transmitted data information to obtain the integrity qualification coefficient of the media advertisement.

[0037] Furthermore, the comparison and analysis of the checksum, hash value, data length and data position of each data block in the transmitted data information includes: A2-1, extracting the initial checksum before the media advertisement is transmitted from the database, and comparing the checksum of the media advertisement with the initial checksum bit by bit.

[0038] A2-2. The check bits in the checksum of the media advertisement that are different from the check bits of the initial checksum are regarded as error bits.

[0039] A2-3. Count the number of error bits and the number of check bits in media advertisements, and perform comparative analysis to obtain the ratio of the number of error bits in media advertisements.

[0040] A2-4. Use the ratio of 1 minus the number of error bits as the checksum pass coefficient for media advertisements.

[0041] A2-5. The hash value qualification coefficient of the media advertisement is analyzed in the same way as the verification qualification coefficient.

[0042] A2-6. Perform consistency analysis on the data length and data position of each data block to obtain the data block qualification coefficient of the media advertisement.

[0043] Furthermore, the consistency analysis comprises: A2-6-1, extracting the initial data length of each data block in the media advertisement from the database, and then comparing the data length of each data block in the media advertisement with its initial data length.

[0044] A2-6-2. If the data length of a data block in a media advertisement is consistent with its initial data length, the data length accuracy coefficient of the data block in the media advertisement is recorded as 1.

[0045] A2-6-3. If the data length of a data block is inconsistent with its initial data length, a deviation value analysis is performed on the data length of the data block and its initial data length to obtain the data length accuracy coefficient of the data block, thereby obtaining the data length accuracy coefficient of each data block in the media advertisement.

[0046] A2-6-4. The average value of the data length accuracy coefficient of each data block is calculated as the data length accuracy coefficient of the media advertisement.

[0047] A2-6-5. Based on the data position of each data block in the media advertisement, calculate the data position accuracy coefficient of the media advertisement.

[0048] It should be added that the specific statistical process of calculating the data position accuracy coefficient of the media advertisement is as follows: extracting the initial data position of each data block in the media advertisement from the database.

[0049] The data position of each data block in the media advertisement is matched and compared with its initial data position, and the data block whose data position is consistent with its initial data position is recorded as a data block with consistent data position.

[0050] The number of data blocks with consistent positions and the number of data blocks are counted, and the ratio of the two is used as the data position accuracy coefficient of the media advertisement.

[0051] A2-6-6. Filter out the minimum value from the data length accuracy coefficient and the data position accuracy coefficient of the media advertisement as the data block qualification coefficient of the media advertisement.

[0052] A2-7. The average value of the checksum qualification coefficient, the hash value qualification coefficient and the data block qualification coefficient is calculated as the integrity qualification coefficient of the media advertisement.

[0053] The embodiment of the present invention ensures that the media advertisement is not tampered with or damaged during the transmission process by adopting a three-level integrity verification mechanism of checksum bit-by-bit comparison, data block length consistency analysis and position verification, thereby improving the transmission integrity and accuracy of the media advertisement and improving the continuity of subsequent advertisement delivery.

[0054] A3. Based on the traffic of media advertisements in the transmission data information at each monitoring time point, a traffic change curve is constructed to analyze the transmission stability qualification coefficient.

[0055] Furthermore, the construction of the flow change curve to analyze the transmission stability qualification coefficient includes: A3-1, constructing the flow change curve of the media advertisement with the monitoring time point as the horizontal coordinate and the flow as the vertical coordinate.

[0056] A3-2. Combine each monitoring time point of the media advertisement with its next adjacent monitoring time point in pairs to obtain each monitoring time group of the media advertisement, and then extract the slope of each monitoring time group from the flow change curve as the flow change rate.

[0057] A3-3. Import the traffic change rate of media advertisements in each monitoring time group into the transmission stability analysis model to obtain the transmission stability qualification coefficient of media advertisements.

[0058] It should be added that the specific analysis process of the transmission stability analysis model is: comparing the traffic change rate of media advertisements in each monitoring time group with the set reference traffic change rate interval.

[0059] If the traffic change rate of media advertisements in a certain monitoring time group is within the set reference traffic change rate interval, the media advertisements in the monitoring time group are recorded as a qualified traffic change monitoring time group.

[0060] The number of qualified monitoring time groups for traffic changes and the number of monitoring time groups are counted, and the ratio of the number of qualified monitoring time groups for traffic changes to the number of monitoring time groups is used as the transmission stability qualification coefficient of the media advertisement.

[0061] The embodiment of the present invention constructs a traffic change curve and introduces a transmission stability analysis model to monitor network fluctuations during advertisement transmission in real time, thereby effectively ensuring the continuity and reliability of advertisement delivery.

[0062] A4. Perform a weighted summation of the encryption qualification coefficient, integrity qualification coefficient and transmission stability qualification coefficient of the media advertisement to obtain the transmission security coefficient of the media advertisement. The transmission security coefficient is calculated by the expression: Calculate the transmission safety factor , , and They are respectively the encryption qualification coefficient, integrity qualification coefficient and transmission stability qualification coefficient of media advertisements. , and are the weights of the encryption qualification coefficient, integrity qualification coefficient and transmission stability qualification coefficient, respectively. , .

[0063] It should be added that in the security of media advertising transmission, encryption is a key means to ensure that data content is not obtained by unauthorized parties. If media advertising contains sensitive information, such as user privacy data (user portraits, behavioral habits, etc.) or commercial secrets (advertising strategies, customer lists, etc.), once the encryption fails, this information may be stolen. In contrast, integrity and stability issues mainly affect the availability of data, while encryption issues directly involve data confidentiality, so its weight is the highest. The integrity of media advertising ensures that the data obtained by the receiving end is complete and can correctly display the advertising content. If the data is incomplete, such as the advertising image is missing some pixels, the advertising copy lacks key information, it may cause the advertisement to fail to display normally or convey wrong information, affecting the advertising effect. Therefore, its weight is second only to the encryption qualification index. Transmission stability mainly involves the stability of media advertising traffic and other aspects during the transmission process. Its main impact is the efficiency and timeliness of media advertising transmission. For example, unstable transmission may cause slow loading of advertisements, but generally will not directly lead to serious security issues such as data leakage or data errors. Therefore, its weight is the lowest, so it is set , in order to facilitate analysis, The specific value can be 0.5. The specific value can be 0.3. The specific value can be 0.2.

[0064] The embodiment of the present invention collects multi-dimensional information of advertising data packets for coupled analysis and constructs a comprehensive transmission security assessment system that includes encryption qualification coefficient, integrity qualification coefficient and transmission stability qualification coefficient, which effectively solves the problem of single traditional advertising transmission security assessment and ensures the confidentiality and stability of advertising data during transmission.

[0065] The data transmission judgment module is used to compare and analyze the transmission safety factor with a set safety threshold to generate a transmission qualification judgment result.

[0066] It should be supplemented that the data transmission determination module includes the following: comparing the transmission safety factor of the media advertisement with a set reference transmission safety factor.

[0067] If the transmission safety factor of the media advertisement is greater than or equal to the set reference transmission safety factor, transmission qualification is regarded as the media advertisement transmission qualification judgment result; otherwise, transmission failure is regarded as the media advertisement transmission qualification judgment result.

[0068] The data content analysis module is used to analyze the video content information of the data packet when the transmission qualification judgment result is transmission qualification, including the advertisement type, each advertisement word, each advertisement picture, the number of key parameters and each key parameter value.

[0069] It should be added that the method of obtaining each advertising word is: obtaining the advertising text through decompilation software or application program interface (API), and then obtaining each advertising word.

[0070] It should be added that the method of obtaining each advertising screen is: install screen capture software on the advertising display terminal or use the system's built-in screenshot function to take a screenshot when the advertisement is displayed to obtain the advertising screen.

[0071] It should be added that the number of key parameters is obtained in the following way: a data dictionary of key advertising parameters is established according to different product or service types. For example, for electronic products, key parameters may include screen size, processor model, memory capacity, etc. For food, they may include ingredients, shelf life, net content, etc. By parsing the text and images of media advertisements, the parameters mentioned therein are matched with the data dictionary, and then the number of key parameters is determined by counting the number of successfully matched parameters.

[0072] It should be added that the key parameter values ​​are obtained as follows: the key parameter values ​​in the advertising text are extracted through text parsing technology. For example, in the media advertising video, "This phone is equipped with 8GB of memory and 128GB of storage capacity" is extracted. Regular expressions and other text processing technologies are used to extract the two key parameter values ​​​​of "8GB" and "128GB". For the parameter values ​​in the picture.

[0073] The data content confirmation module is used to perform multi-dimensional comparative analysis based on the video content information of the media advertisement to obtain the control instruction of the media advertisement.

[0074] See also Figure 3 As shown, exemplarily, the multi-dimensional comparative analysis based on the video content information of the media advertisement includes: B1, matching and analyzing the advertisement words and the advertisement pictures respectively to obtain the violation coefficient of the media advertisement.

[0075] Furthermore, the matching analysis of the advertisement words and the advertisement pictures respectively includes: B1-1, extracting a set of illegal words in media advertisements from a database.

[0076] B1-2. Match and compare each advertising word in the media advertisement with the set of illegal words.

[0077] B1-3. If an advertising word in a media advertisement matches an illegal word in the illegal word set, 1 is used as the advertising word violation coefficient of the media advertisement. If all advertising words in the media advertisement do not match any illegal words in the illegal word set, 0 is used as the advertising word violation coefficient of the media advertisement.

[0078] B1-4. Extract the collection of illegal images of media advertisements from the database, and then match and analyze it with each advertising image of the media advertisement to obtain the illegal coefficient of the advertising image of the media advertisement.

[0079] It should be added that the specific analysis process of the media advertisement advertising screen violation coefficient is as follows: each advertising screen of the media advertisement is matched and compared with the collection of violation screens.

[0080] If the advertising images of the media advertisement do not match the collection of illegal images, 0 will be used as the illegal coefficient of the media advertisement advertising image; otherwise, 1 will be used as the illegal coefficient of the media advertisement advertising image.

[0081] B1-5. Extract the maximum value from the advertising word violation coefficient and the advertising image violation coefficient of the media advertisement as the violation coefficient of the media advertisement.

[0082] B2. Calculate the deviation of the number of key parameters and the value of each key parameter to obtain the deviation coefficient of the media advertisement.

[0083] Furthermore, the deviation calculation of the key parameter number and each key parameter value includes: B2-1, extracting the reference key parameter number of each advertisement type from the database, and then extracting the reference key parameter number of the advertisement type to which the media advertisement belongs.

[0084] B2-2. The ratio of the difference between the number of reference key parameters and the number of key parameters of the media advertisement to the number of reference key parameters is taken as the deviation coefficient of the key parameters of the media advertisement.

[0085] B2-3. Extract each reference key parameter value of each advertisement type from the database, and then extract each reference key parameter value of the advertisement type to which the media advertisement belongs.

[0086] B2-4. Match and compare each key parameter value of the media advertisement with its reference key parameter value. If a key parameter value in the media advertisement is inconsistent with its reference key parameter value, the key parameter value in the media advertisement is recorded as a deviation key parameter value.

[0087] B2-5. The ratio of the number of statistical deviation key parameter values ​​to the number of key parameter values ​​is used as the key parameter deviation coefficient of media advertising.

[0088] B2-6. Perform weighted summation of the key parameter deviation coefficient and the key parameter deviation coefficient to obtain the media advertising deviation coefficient, where the media advertising deviation coefficient is calculated by the expression: Calculate the coefficient of deviation of media advertising , and are the key parameter deviation coefficient and the key parameter deviation coefficient, respectively. and are the set key parameter deviation coefficient and the weight of the key parameter deviation coefficient, , .

[0089] It should be added that the key parameter deviation coefficient is obtained by taking the difference between the number of reference key parameters and the number of key parameters of media advertisements and then calculating the ratio with the number of reference key parameters. This coefficient can reflect the deviation of the number of key parameters of media advertisements from the standard of the type of advertisements they belong to. The key parameter deviation coefficient can be regarded as a basic indicator of the authenticity of advertisements. If the advertisement cannot even guarantee that the basic number of key parameters meets the standards of the type it belongs to, then there is a great doubt about the authenticity of the advertisement content. The key parameter deviation coefficient is obtained by taking the ratio of the number of statistical deviation key parameter values ​​to the number of key parameter values. It mainly focuses on the matching of each key parameter value in the media advertisement with the reference key parameter value. On the basis that the number of key parameters of the advertisement meets the requirements, the accuracy of the key parameter values ​​becomes particularly important. This coefficient can accurately capture the deviation of the advertisement in detailed information. For products that require accurate information to make purchasing decisions (such as electronic products, medical devices, etc.), the key parameter deviation coefficient can well reflect whether the advertisement is true and reliable in details. However, the key parameter deviation coefficient has a more fundamental impact on the overall structure of the advertisement and the integrity of basic information, so it is relatively high in the weight ranking, so it is set , in order to facilitate analysis, The specific value can be 0.6. The specific value can be 0.4.

[0090] B3. Extract each advertisement word of each historical media advertisement from the database, and match and analyze it with each advertisement word in the advertisement to obtain the plagiarism coefficient of the media advertisement.

[0091] Furthermore, the matching analysis with each advertising word in the advertisement includes: B3-1, matching and comparing each advertising word in the media advertisement with each advertising word in each historical media advertisement, obtaining the number of matching advertising words between the media advertisement and each historical media advertisement, and using the ratio of the number of matching advertising words as the word plagiarism coefficient between the media advertisement and each historical media advertisement.

[0092] B3-2. Sort the word plagiarism coefficients of media advertisements and historical media advertisements from large to small, and extract the word plagiarism coefficient that ranks first as the plagiarism coefficient of media advertisements and historical media advertisements.

[0093] B4. Filter out the maximum value from the violation coefficient, deviation coefficient and plagiarism coefficient of media advertisements as the data content deviation coefficient, and then subtract 1 from the data content deviation coefficient as the data content safety coefficient of media advertisements.

[0094] B5. Compare the data content security factor of the media advertisement with the set reference data content security factor. If the data content security factor of the media advertisement is greater than or equal to the set reference data content security factor, completing the advertisement delivery will be used as a control instruction for the media advertisement. Otherwise, blocking the advertisement delivery will be used as a control instruction for the media advertisement.

[0095] The embodiment of the present invention analyzes the violation coefficient, deviation coefficient and plagiarism coefficient through the video content information of the media advertisement, realizes the triple compliance review within the video, and generates control instructions, thereby increasing the attention paid to the violation and plagiarism of the media advertisement, and ensuring the legality and originality of the advertisement content from the source.

[0096] The database is used to store the initial checksum before the media advertisement is transmitted, store the initial data length of each data block in the media advertisement, store the set of illegal words in the media advertisement, store the number of reference key parameters of each advertisement type, store each reference key parameter value of each advertisement type, and store each advertisement word of each historical media advertisement.

[0097] The data control feedback terminal is used to execute control instructions to complete advertisement delivery or advertisement blocking.

[0098] The above contents are merely examples and explanations of the concept of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the concept of the invention or exceed the scope defined by the present invention, they shall all fall within the protection scope of the present invention.

Filter out the maximum value from the violation coefficient, deviation coefficient and plagiarism coefficient of the media advertisement as the data content deviation coefficient, and then subtract 1 from the data content deviation coefficient as the data content safety coefficient of the media advertisement; B5. Compare the data content security factor of the media advertisement with the set reference data content security factor. If the data content security factor of the media advertisement is greater than or equal to the set reference data content security factor, completing the advertisement delivery will be used as a control instruction for the media advertisement. Otherwise, blocking the advertisement delivery will be used as a control instruction for the media advertisement.

8. The data security online intelligent monitoring and management system according to claim 7 is characterized by: The matching analysis of the advertisement words and the advertisement pictures respectively includes: Extract the set of illegal words in media advertisements from the database; Match and compare each advertising word in the media advertisement with the set of illegal words; If a certain advertising word in a media advertisement matches a certain illegal word in the illegal word set, 1 is used as the advertising word violation coefficient of the media advertisement; if all advertising words in the media advertisement do not match any illegal words in the illegal word set, 0 is used as the advertising word violation coefficient of the media advertisement; Extracting a collection of illegal images of media advertisements from a database, and then matching and analyzing the collection with each advertising image of the media advertisements to obtain the illegal coefficient of the advertising image of the media advertisements; The maximum value is extracted from the advertising word violation coefficient and the advertising picture violation coefficient of the media advertisement as the violation coefficient of the media advertisement.

9. The data security online intelligent monitoring and management system according to claim 7, characterized in that: The step of calculating the deviation of the number of key parameters and the values ​​of each key parameter includes: Extracting the number of reference key parameters of each advertisement type from the database, and then extracting the number of reference key parameters of the advertisement type to which the media advertisement belongs; The ratio of the difference between the number of reference key parameters and the number of key parameters of media advertisements to the number of reference key parameters is taken as the deviation coefficient of the key parameters of media advertisements; Extracting each reference key parameter value of each advertisement type from the database, and then extracting each reference key parameter value of the advertisement type to which the media advertisement belongs; Match and compare each key parameter value of the media advertisement with its reference key parameter value. If a key parameter value in the media advertisement is inconsistent with its reference key parameter value, the key parameter value in the media advertisement is recorded as a deviation key parameter value; The ratio of the number of statistical deviation key parameter values ​​to the number of key parameter values ​​is used as the key parameter deviation coefficient of media advertising; The deviation coefficient of media advertisement is obtained by weighted summing the key parameter deviation coefficient and the key parameter deviation coefficient.

10. The data security online intelligent monitoring and management system according to claim 7, characterized in that: The matching analysis with each advertisement word in the advertisement includes: Match and compare each advertising word of the media advertisement with each advertising word of each historical media advertisement, obtain the number of matching advertising words between the media advertisement and each historical media advertisement, and use the ratio of the number of matching advertising words to the number of advertising words as the word plagiarism coefficient between the media advertisement and each historical media advertisement; The word plagiarism coefficients of media advertisements and historical media advertisements are sorted from large to small, and the word plagiarism coefficient that ranks first is extracted as the plagiarism coefficient of media advertisements and historical media advertisements.
