[0045] In the following, only some exemplary embodiments are briefly described. As those skilled in the art can recognize, the described embodiments can be modified in various different ways without departing from the spirit or scope of the present application. Therefore, the drawings and the description are considered to be exemplary in nature and not restrictive.

[0046] The technical solution of the present application and how the technical solution of the present application solves the above technical problems will be described in detail below with specific embodiments.

[0047] An embodiment of the present application provides a method, a device, and a system for monitoring delivered content to achieve automatic monitoring of delivered content, reduce costs, improve accuracy, and reduce the false recognition rate. This technical solution involves a media playback terminal and a server. Among them, the media playback terminal generally refers to a display device that can play multimedia information, and its main function is to display the playback content. The installation locations include but are not limited to bus stops, elevators, airports, shopping malls, etc. The server is a device with the functions of issuing and identifying. It communicates remotely with the media playback terminal, can issue a dynamic verification code and delivered content (such as an advertisement) to the media playback terminal, and can also identify the screenshot image containing the dynamic verification code uploaded by the media playback terminal to determine whether the delivered content is played abnormally on the media playback terminal side, so as to achieve the purpose of monitoring and alarming.

[0048] See Figure 1 , an embodiment of the present application provides a method for monitoring delivered content, which is applied to a media playback terminal and includes:

[0049] S101: Receive the delivered content and verification information issued by the server;

[0050] Among them, the delivered content can be multimedia information, such as an advertisement video provided by an advertiser, etc. This embodiment does not make specific limitations on this.

[0051] S102: Analyze the verification information to obtain a dynamic verification code;

[0052] Among them, the above dynamic verification code may include at least one of text, numbers, symbols, and shapes.

[0053] S103: Render the dynamic verification code onto the playback screen of the delivered content;

[0054] Among them, rendering refers to the process of generating an image from a model by software. The model is a description of a three-dimensional object in a strictly defined language or data structure, which includes geometric, viewpoint, texture, and lighting information. In this embodiment, the rendering specifically means generating a corresponding image of the dynamic verification code and synthesizing it into the playback screen.

[0055] S104: Take a screenshot of the playback screen to obtain a screenshot image;

[0056] Among them, taking a screenshot refers to intercepting the information on the display screen and is a way to capture an image. In this embodiment, taking a screenshot of the dynamically played screen can obtain the screen image corresponding to the screenshot moment, which can be called a screenshot image for easy understanding. For a played video, it can be understood as capturing the image of a corresponding frame at a certain moment.

[0057] S105: Upload the screenshot image to the server, and the screenshot image is used for the server to monitor whether the delivered content is abnormal.

[0058] In one implementation, the above step S103 may include:

[0059] In the case where the position information is also obtained by parsing the verification information, render the dynamic verification code onto the playback screen of the delivered content according to the position specified by the position information.

[0060] In another implementation, the above step S103 may include:

[0061] In the case where multiple dynamic verification codes and their respective validity periods are obtained by parsing, determine the validity period in which the current moment is located, and render the dynamic verification code corresponding to the validity period onto the playback screen of the delivered content.

[0062] In this embodiment, the information sent by the server can also be encrypted first. After receiving it, the media playback terminal decrypts it accordingly and then performs subsequent operations, thereby improving the security of data. There are various encryption and decryption algorithms involved, including but not limited to: MD5 (Message-Digest Algorithm), SHA1 (Secure Hash Algorithm 1), HMAC (Hash-based Message Authentication Code), AES (Advanced Encryption Standard) / DES (Data Encryption Standard) / 3DES, RSA (Rivest-Shamir-Adleman algorithm), ECC (Error Correcting Code), and so on.

[0063] In the method provided in this embodiment, by rendering the dynamic verification code sent by the server onto the playback screen of the placement content, taking a screenshot of the obtained screenshot image and uploading it to the server to monitor whether the placement content is abnormal, the automatic monitoring of the placement content is realized. There is no need to configure a separate acquisition device, which reduces the cost. Moreover, the interference factors of the surrounding environment can be excluded based on the screenshot image monitoring. Compared with the acquisition device, the image is clearer, thereby improving the accuracy, reducing the misrecognition rate, and greatly increasing the difficulty of tampering with the placement content based on the dynamic verification code.

[0064] See Figure 2 , another embodiment of the present application provides a method for monitoring placement content, which is applied to a server and includes:

[0065] S201: Generate verification information containing a dynamic verification code, where the dynamic verification code is used to be rendered by the media playback terminal onto the playback screen of the placement content;

[0066] Among them, the above dynamic verification code may include at least one of text, numbers, symbols, and shapes.

[0067] S202: Send the placement content and the verification information to the media playback terminal;

[0068] S203: Receive the screenshot image sent by the media playback terminal after taking a screenshot of the playback screen;

[0069] Among them, the screenshot image of the media playback terminal contains the received dynamic verification code. Therefore, verification can be performed based on this.

[0070] S204: Monitor whether the content played on the media player terminal is abnormal according to the screenshot image.

[0071] In one implementation, the above step S204 may include:

[0072] Parse the dynamic verification code from the screenshot image, compare it with the locally generated dynamic verification code, and determine that the content played on the media player terminal is abnormal when the matching degree is less than the threshold.

[0073] Among them, the matching degree refers to the matching degree between the parsed dynamic verification code and the locally generated dynamic verification code, and various matching algorithms such as similarity can be used to calculate it, which is not specifically limited here. The above threshold can be set as needed, such as 70%, 80% or 90%, etc., and the specific value is not limited.

[0074] In one implementation, the above determining that the content played on the media player terminal is abnormal when the matching degree is less than the threshold may include:

[0075] Determine that the content played on the media player terminal is abnormal when the matching degree is less than the threshold and the number of comparison times reaches the specified number of times.

[0076] Among them, the specified number of times can be set in advance as needed, such as 3 times or 5 times, etc., and the specific value is not limited. For example, if the comparison is made 3 times and the matching degrees of all 3 times are less than the threshold of 80%, it is determined that the played content is abnormal.

[0077] The above method of identifying abnormalities based on the matching degree can change the identification accuracy by setting the threshold. For example, the identification accuracy can be improved by increasing the value of the threshold, and the identification accuracy can be reduced by decreasing the value of the threshold. The setting method is flexible and convenient and easy to implement. The above method of identifying abnormalities based on the matching degree and the number of comparison times can set a certain error rate for monitoring, avoiding misidentification caused by accidental interference factors such as network delay or transmission error, that is, not identifying as abnormal within the allowable range of the specified number of times, and only identifying as abnormal when exceeding the specified number of times, thus improving compatibility and being more flexible in application.

[0078] In one implementation, the above verification information further includes location information, which is used to specify the rendering position of the dynamic verification code in the playback screen; and / or, multiple generated dynamic verification codes have their respective validity periods.

[0079] The above method provided in this embodiment realizes the automatic monitoring of the delivered content by generating a dynamic verification code and sending it to the media playback terminal, receiving the screenshot image sent by the media playback terminal after rendering the dynamic verification code on the playback screen, and monitoring whether the delivered content is abnormal based on the screenshot image. It does not require the configuration of a separate acquisition device, reducing costs. Moreover, monitoring based on the screenshot image can exclude interference factors in the surrounding environment. Compared with the acquisition device, the image is clearer, thus improving accuracy and reducing the misrecognition rate. In addition, the use of the dynamic verification code greatly increases the difficulty of tampering with the delivered content.

[0080] Refer to Figure 3 , another embodiment of the present application provides a method for monitoring delivered content, which is applied to a media playback terminal and includes:

[0081] S301: Receive the delivered content and verification information sent by the server;

[0082] S302: Analyze the verification information to obtain the position information and multiple dynamic verification codes, as well as the validity period corresponding to each dynamic verification code;

[0083] Among them, the above dynamic verification code may include at least one of text, numbers, symbols, and shapes. The above position information may be pixel coordinate information, and based on this position information, the display position of the dynamic verification code on the playback screen can be determined. To minimize interference with the normal delivered content and affect user viewing, preferably, the display position of the dynamic verification code can be set at the edge or corner of the playback screen according to the position information, and the size can be set as small as possible so that it is not easily observable by the user, thereby ensuring a smooth user experience.

[0084] The above validity period is usually a period of time, such as one day, one week, or one month, etc. The dynamic verification code is valid within the validity period, and it becomes invalid after exceeding this validity period. In the case of multiple dynamic verification codes, a validity period can be set for each dynamic verification code, usually set to different validity periods, and can be set to consecutive validity periods. For example, 7 dynamic verification codes are set from Monday to Sunday, and the validity period of each dynamic verification code is 1 day, etc., which is not specifically limited.

[0085] S303: Determine the validity period in which the current moment is located, and render the dynamic verification code corresponding to this validity period to the playback screen of the delivered content at the position specified by the above position information;

[0086] For example, if the current moment is 10:00 am on Monday and the corresponding validity period is from Monday to Friday, then select the dynamic verification code within this validity period for rendering.

[0087] S304: Take a screenshot of the playback screen to obtain a screenshot image;

[0088] Among them, the screenshot can capture the entire screen of the playback screen or a partial area, as long as it contains the dynamic verification code, without specific limitations. The screenshot operation can be performed regularly, such as setting a certain period, and when the period arrives, the screenshot is uploaded, so that the server can perform identification and monitoring based on multiple screenshot results, improving the accuracy of monitoring.

[0089] S305: Upload the screenshot image to the server, and the screenshot image is used for the server to monitor whether the delivered content is abnormal.

[0090] Among them, the screenshot image can also be encrypted first and then uploaded to the server. After receiving it, the server decrypts it first and then performs subsequent operations to improve security. The process of encryption and decryption will not be elaborated here.

[0091] See Figure 4 , which is a schematic diagram of a media playback terminal for monitoring delivered content in an embodiment of the present application. As shown in the figure, the media playback terminal has a playback control function and a screenshot function. After receiving the playback material and the dynamic verification code sent by the server, it can perform a playback operation through the playback control function, and at the same time, it can parse out the dynamic verification code and render it into the playback screen. During the playback process, the screenshot function can capture screenshots regularly to obtain the screenshot image and upload it to the server, triggering the server to monitor whether the playback content is abnormal.

[0092] See Figure 5 , another embodiment of the present application provides a method for monitoring delivered content, which is applied to a server and includes:

[0093] S501: Generate verification information including a dynamic verification code and location information. The dynamic verification code is used for the media playback terminal to render it into the playback screen of the delivered content, and the location information is used to specify the rendering position of the dynamic verification code in the playback screen;

[0094] Among them, the above dynamic verification code can include at least one of text, numbers, symbols, and shapes.

[0095] In one implementation, the above dynamic verification codes can be multiple and each has its own corresponding validity period.

[0096] S502: Send the delivered content and the verification information to the media playback terminal;

[0097] S503: Receive the screenshot image sent by the media playback terminal after capturing the playback screen;

[0098] S504: Parse out the dynamic verification code from the screenshot image and compare it with the locally generated dynamic verification code;

[0099] S505: When the matching degree is less than the threshold, it is determined that the content played by the media player terminal is abnormal.

[0100] In one implementation, the above method may further include:

[0101] After determining that the content played by the media player terminal is abnormal, an alarm message is sent to indicate that the played content is abnormal. Among them, the alarm message can be sent to the service server, and the service server will perform corresponding processing or prompt relevant personnel, and manual review and timely processing will be carried out to repair the abnormality, etc.

[0102] For example, if the locally generated dynamic verification code is the text "Smart Bus" and the dynamic verification code parsed from the screenshot image is "Smart", then the matching degree is 50%, which is less than the threshold of 80%, so it can be determined that the played content is abnormal.

[0103] In one implementation, the above step S505 may include:

[0104] When the matching degree is less than the threshold and the number of comparison times reaches the specified number, it is determined that the content played by the media player terminal is abnormal.

[0105] Among them, the matching degree being less than the threshold means that within the specified number of times, the matching degree of each comparison is less than the threshold.

[0106] See Figure 6 , which is a schematic diagram of the server monitoring the played content in an embodiment of the present application. As shown in the figure, the server has a service function and an image recognition function. Through the service function, a dynamic verification code can be generated and sent to the media player terminal together with the playback material. After receiving the screenshot image uploaded by the media player terminal, based on the image recognition function, the dynamic verification code is parsed from the screenshot image and compared with the locally generated dynamic verification code, and it is determined whether the played content of the media player terminal is abnormal according to the comparison result.

[0107] See Figure 7 , an embodiment of the present application provides a device for monitoring played content, which is applied to a media player terminal and includes:

[0113] In one implementation, the rendering module 703 can be used to:

[0114] In the case where position information is also obtained by parsing the verification information, render the dynamic verification code to the playback screen of the delivered content at the position specified by the position information.

[0115] In another implementation, the rendering module 703 can be used to:

[0116] In the case where multiple dynamic verification codes and their respective expiration periods are obtained by parsing, determine the expiration period in which the current moment is located, and render the dynamic verification code corresponding to the expiration period to the playback screen of the delivered content.

[0117] Wherein, the above dynamic verification code can include at least one of text, numbers, symbols, and shapes.

[0123] A monitoring module 804 for monitoring whether the delivered content of the media playback terminal is abnormal according to the screenshot image.

[0124] In one implementation, the monitoring module 804 can be used to:

[0125] Parse the dynamic verification code from the captured screen image, compare it with the locally generated dynamic verification code, and determine that the content played by the media playback terminal is abnormal when the matching degree is less than the threshold.

[0126] In one implementation, when the matching degree is less than the threshold, the monitoring module 804 determines that the content played by the media playback terminal is abnormal, which may include:

[0127] Determine that the content played by the media playback terminal is abnormal when the matching degree is less than the threshold and the number of comparison times reaches the specified number.

[0128] Wherein, the above verification information further includes position information, which is used to specify the rendering position of the dynamic verification code in the playback screen; and / or, the generated dynamic verification codes are multiple and each has its own corresponding validity period.

[0129] Wherein, the above dynamic verification code may include at least one of text, numbers, symbols, and shapes.

[0130] The above device provided in this embodiment realizes automatic monitoring of the played content by generating a dynamic verification code and sending it to the media playback terminal, receiving the captured screen image sent by the media playback terminal after rendering the dynamic verification code to the playback screen, and monitoring whether the played content is abnormal based on the captured screen image. It does not require a separate acquisition device, reduces costs, and can exclude interference factors in the surrounding environment based on the captured screen image. Compared with the acquisition device, the image is clearer, thus improving accuracy, reducing the misrecognition rate, and greatly increasing the difficulty of tampering with the played content based on the dynamic verification code.

[0131] See Figure 9 , an embodiment of the present application provides a system for monitoring played content, including: a media playback terminal 901 and a server 902. Among them, the media playback terminal 901 includes the above Figure 7 The device for monitoring played content shown, and the server 902 includes the above Figure 8 The device for monitoring played content shown.

The media playback terminal renders the dynamic verification code on the playback screen, takes a screenshot, and uploads the screenshot image. The server monitors whether the delivered content is abnormal based on the screenshot image, realizing the automatic monitoring of the delivered content. There is no need to configure a separate acquisition device, which reduces costs. Moreover, monitoring based on the screenshot image can exclude interference factors in the surrounding environment.
