[0002] In various market segments such as traditional digital television, internet broadband television, and video websites, viewership data is a crucial reference for program production, scheduling, and adjustment. Existing viewership data collection methods include diary card methods and measurement instrument methods.

This data is then reported to a server for processing at a predetermined time via telephone or broadband network. These methods have limited sample coverage and the collected data is easily tampered with. Therefore, in recent years, blockchain-based viewership data collection methods have been proposed.

[0024] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the specific technical solutions of this application will be further described in detail below with reference to the accompanying drawings of the embodiments of this application. The following embodiments are used to illustrate this application, but are not intended to limit the scope of this application.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein is for the purpose of describing embodiments of this application only and is not intended to limit this application.

[0026] In the following description, references to "some embodiments," "this embodiment," "this application embodiment," and examples, etc., describe a subset of all possible embodiments. However, it is understood that "some embodiments" may be the same subset or different subset of all possible embodiments and may be combined with each other without conflict.

[0027] The network architecture and business scenarios described in the embodiments of this application are for the purpose of more clearly illustrating the technical solutions of the embodiments of this application, and do not constitute a limitation on the technical solutions provided in the embodiments of this application. Those skilled in the art will understand that, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in the embodiments of this application are also applicable to similar technical problems.

[0028] This application provides a method for adding a playback device to a blockchain. The method is applied to a first playback device to be added to the blockchain. During implementation, the first playback device has at least data processing capabilities and can be various types of devices with video, audio, text, or image playback capabilities. For example, the first playback device may include a mobile phone, tablet computer, laptop computer, desktop computer, and smart TV. The functions implemented by this method can be achieved by the processor in the first playback device calling program code. Of course, the program code can be stored in a computer storage medium. Therefore, the first playback device includes at least a processor and a storage medium.

[0029] Figure 1 This is a schematic diagram illustrating the implementation flow of the playback device joining method provided in the embodiments of this application, as shown below. Figure 1 As shown, the method may include the following steps 101 to 103:

[0030] Step 101: Collect playback data of at least one first program.

[0031] In some embodiments, the first playback device includes a data acquisition module; the first playback device can acquire playback data of at least one first program through the data acquisition module.

[0032] In some embodiments, when the first playback device plays the first program, it may automatically trigger the viewership data statistics program in the data acquisition module, which records at least the playback data of the first program.

[0033] In some embodiments, the playback data of the first program includes at least one frame of the first program; the at least one frame may be a video frame selected from a playback segment of the first program that has or includes key information; the key information may include male and female lead actors, etc. These playback images may be in the format of bmp, jpg, or png, etc., in the data acquisition module.

[0034] In some embodiments, the playback data of the first program may also include the time position information of the at least one frame of the playback image in the first program.

[0035] In some embodiments, the data acquisition module may also record program information of the first program based on the viewership data statistics program; the program information includes program name, program duration and program cast and crew, etc.

[0036] In some embodiments, the data acquisition module may also record device information of the first playback device based on the viewing data statistics program; the device information includes device type and Media Access Control Address (MAC), etc.; the device type includes smart TVs, mobile phones, tablets, laptops and desktops, etc., and the device type can be used to understand the audience's program viewing path; the MAC address can be used as a unique identifier for the first playback device.

[0037] In some embodiments, the first playback device further includes a storage module, which can use the playback data of the first program, the program information of the first program, and the device information of the first playback device collected by the data acquisition module as the viewing data information of the first program. The storage module packages and compresses the viewing data information and then saves it.

[0038] Step 102: Based on the playback data, obtain reference data corresponding to the playback data from the blockchain.

[0039] In some embodiments, the first playback device further includes a data processing module. The storage module of the playback device first marks the viewing data information collected by the data acquisition module as unprocessed data, sends the unprocessed data to the data processing module to request the data processing module to process it, and then marks the viewing data information processed by the data processing module as processed data.

[0040] In some embodiments, the data processing module performs hash processing on at least one frame of the playback image in the playback data of the first program in the viewing data information to obtain at least one first hash value; the first playback device broadcasts the program name of the first program and the time position information of each playback image in the first program, and requests at least one third playback device on the blockchain to provide the first playback device with the second hash value of the reference image corresponding to each playback image in the first program according to the broadcast content.

[0041] In some embodiments, the third playback device can be a playback device that has played the first program on the blockchain, or it can be any playback device on the blockchain that has not played the first program. That is, the third playback device can be any playback device on the blockchain. It is understood that after the first program is launched on the relevant platform, any playback device on the blockchain has the right to view and retrieve the first program. Therefore, the third playback device can obtain reference images corresponding to the playback images in the first program based on the program name of the first program broadcast by the first playback device and the time position of each playback image in the first program, and then send the second hash values ​​of each reference image to the first playback device.

[0042] In this embodiment, the hash algorithm used to perform hash processing on the played image can be an average hash algorithm, a perceptual hash algorithm, or a difference hash algorithm, etc., and this embodiment does not limit the specific hash algorithm used. After processing the played image using the hash algorithm, a fixed-length binary value, namely the first hash value, can be obtained. The first hash value obtained by the hash algorithm is unique and unpredictable. If the played image changes or is tampered with, the generated hash value will be very different from the previous hash value. In this way, it is relatively easy to determine whether the played image is a tampered image, thereby ensuring the accuracy of the viewing data.

[0043] In some embodiments, the data processing module may determine the similarity between the playback image and the reference image based on the similarity between the first hash value and the second hash value.

[0044] Understandably, after receiving the second hash value of the reference image sent by at least one third playback device, the data processing module performs a similarity calculation between it and the corresponding first hash value; for example, the data processing module can calculate the similarity between the first hash value and the second hash value according to the Hamming distance calculation method, as shown in the following formula (1):

[0045]

[0046] Where d(x,y) represents the similarity between the i-th playback image and the corresponding reference image; x[i] represents the first hash value of the i-th playback image; and y[i] represents the second hash value of the reference image corresponding to the i-th playback image.

[0047] Step 103: If the similarity between the playback data and the reference data meets the first condition, add itself to the blockchain according to the DAG rule.

[0048] Understandably, in this embodiment of the application, the first playback device is directly added to the blockchain, without miners needing to package the playback data into blocks and add the blocks to the blockchain; the blockchain in this embodiment of the application does not have the concept of "blocks" and does not require miners to package them, thus saving transaction fees and improving data processing speed.

[0049] In some embodiments, if the similarity between the playback image in M ​​frames and the corresponding reference image is greater than or equal to a first threshold, it is determined that the similarity between the playback data and the reference data satisfies a first condition; wherein M is greater than or equal to 1 and less than or equal to the number of playback images, i.e., 1≤M≤the number of playback images; the first threshold can be preset according to actual needs.

[0050] In some embodiments, if the similarity between the playback data and the reference data satisfies a first condition, i.e., when the similarity between the M-frame playback image and the corresponding reference image is greater than or equal to a first threshold, consensus verification is requested from N second playback devices on the blockchain; where N is greater than or equal to 1 and less than or equal to the number of playback devices on the blockchain; that is, 1 ≤ N ≤ the number of playback devices on the blockchain. If the first playback device passes the consensus verification of the N second playback devices, it connects itself to each of the N second playback devices in a first direction.

[0051] In some embodiments, the first direction is from the first playback device to the second playback device.

[0052] In some embodiments, after confirming that the similarity between the playback data and the reference data meets the first condition, the data processing module notifies the blockchain module of the first playback device to add the first playback device to the blockchain, so as to prevent the viewing data in the first playback device from being tampered with when calculating the viewing parameters.

[0053] In some embodiments, before the first playback device to be added to the blockchain, the blockchain includes at least one genesis playback device. When the first playback device is added to the blockchain, the first playback device performs consensus verification with some or all of the genesis playback devices. After successful verification, the first playback device and the aforementioned some or all of the genesis playback devices are connected in the same direction, i.e., the first playback device is added to the blockchain. When other subsequent playback devices are added to the blockchain, the same method is used to connect the first playback device with N second playback devices on the blockchain for consensus verification, where the second playback devices include the genesis playback device. After successful consensus verification, the first playback device is connected to the N second playback devices respectively. Wherein, 1 ≤ N ≤ the number of playback devices on the blockchain, i.e., the N second playback devices are a portion of the playback devices on the blockchain. This process continues until all the first playback devices are finally added to the blockchain, generating a blockchain with a DAG topology.

[0054] It should be noted that, in this embodiment of the application, the playback device to be added to the chain is referred to as the first playback device; after the first playback device is added to the chain, it can be regarded as the second playback device on the blockchain.

[0055] In this embodiment, the first playback device performs consensus verification with N second playback devices on the blockchain. After the consensus verification is successful, the first playback device is connected to the corresponding N second playback devices. This can also be described as the first playback device confirming a transaction with the N second playback devices. This embodiment does not limit the scope of this embodiment.

[0056] In some embodiments, when the first playback device joins the chain, it can confirm transactions with the previous N second playback devices; for example, Figure 2 This is a schematic diagram of the topology of the DAG blockchain network provided in the embodiments of this application, as shown below. Figure 3 As shown, when the first playback device 1 joins the chain, the first playback device 1 confirms the transaction with the genesis playback device 1 and / or the genesis playback device 2; when the first playback device 2 joins the chain, the first playback device 2 confirms the transaction with the genesis playback device 2 and the first playback device node 1 after joining the chain; and so on, when the first playback device q joins the chain, it only needs to confirm the transaction with the first two first playback devices after joining the chain.

[0057] Understandably, N is greater than or equal to 1, and less than the number of playback devices on the blockchain. This means that when the first playback device joins the blockchain, it only needs to confirm its transaction with a subset of the playback devices on the blockchain. Compared to traditional blockchains that require confirmation with all playback devices on the blockchain, this increases the speed at which the first playback device joins the blockchain.

[0058] In other embodiments, when the first playback device joins the blockchain, it can confirm transactions with any N second playback devices on the blockchain; for example, Figure 3 This is a schematic diagram of the topology of another DAG blockchain network provided in this application embodiment; when the first playback device 1 joins the chain, the first playback device 1 can confirm the transaction with the genesis playback device 1 and / or the genesis playback device 2; when the first playback device 2 joins the chain, the first playback device 2 can confirm the transaction with the genesis playback device 2 and playback device node 1; when the first playback device 3 joins the chain, the first playback device 3 can confirm the transaction with the genesis playback device 1...; and so on, the remaining first playback devices confirm the transaction with their corresponding N arbitrary second playback devices respectively, generating a blockchain with a DAG topology.

[0059] Understandably, in the example above, since the first playback device can confirm transactions with any N second playback devices without needing to confirm transactions with the first N playback devices in the order they joined the chain, it is possible to support multiple first playback devices simultaneously and in parallel confirming transactions with their corresponding N arbitrary second playback devices. That is, playback device 1 confirming transactions with the genesis playback device and / or genesis playback device 2, and playback device 3 confirming transactions with the genesis playback device 1, can occur simultaneously, thus improving the joining speed of the first playback devices.

[0060] In this application embodiment, the playback device can also be described as a playback device node, and the genesis device can also be described as a genesis device node, genesis node, etc. This application embodiment does not limit this.

[0061] This application provides a viewership statistics method, which can be applied to electronic devices. Figure 4 This is a schematic diagram illustrating the implementation process of the viewership statistics method provided in the embodiments of this application, as follows: Figure 4 As shown, the method includes step 401 and step 403:

[0062] Step 401: Determine the fourth playback device that has played the first program on the pre-generated blockchain; wherein the topology of the blockchain is a DAG, and the nodes of the DAG include at least the fourth playback device;

[0063] Step 402: Obtain the playback data of the first program recorded by the fourth playback device;

[0064] Step 403: At least based on the playback data of the first program, calculate the viewership parameters of the first program.

[0065] In some embodiments, the viewership parameters may include viewership ratings and / or click-through rates. The viewership parameters of the first program during a given time period can be determined based on the ratio of the number of fourth playback devices that played the first program on the blockchain to the total number of playback devices. This application embodiment does not limit the duration of the time period.

[0066] Understandably, the blockchain used for viewership statistics is generated based on the rules of a directed acyclic graph, which increases the transaction speed of the blockchain used for viewership statistics, thereby increasing the speed of viewership statistics.

[0067] Viewership statistics refer to the statistics of video program ratings or click-through rates. Ratings or click-through rates indicate the percentage of people who watched a particular program within a certain period of time out of the total audience. In different market segments such as traditional digital television, internet broadband television, and video websites, ratings and click-through rates are key indicators for evaluating the effectiveness and popularity of program production, and are important references for program production, scheduling, and adjustments.

[0068] Traditional viewership data collection methods, such as the diary card method and the meter method, involve selecting a small sample of users, manually recording viewership information, or collecting viewership data using observation instruments. This data is then reported to a server for processing at a predetermined time via telephone or broadband network. With the development of blockchain technology, its immutable nature is also being applied to viewership rating methods to improve the accuracy of ratings.

[0069] The existing methods for statistical analysis of viewership data have several drawbacks, including limited sample size coverage, high data analysis costs, susceptibility to data tampering, and low data accuracy.

[0070] In some embodiments, the blockchain-based viewership rating statistics method employs a public blockchain with a chain structure. However, it suffers from slow processing speed and high costs. Especially with the current explosion of massive amounts of short video content, how to accelerate data processing and reduce data processing costs while ensuring that the statistical sample size is no longer limited and the statistical data is not easily tampered with is a new challenge facing viewership data statistics.

[0071] This application provides a method and system for viewership data statistics based on directed acyclic graphs (DAGs). By leveraging the characteristics of DAGs—fast data processing, strong scalability, and high security—it solves the aforementioned problems in the viewership data statistics process.

[0072] Digital television broadcasting, broadband internet television, and mobile short videos are flourishing, and the quality of a program's production directly determines its popularity. Television ratings and short video click-through rates are important indicators for evaluating the popularity and production quality of films and television programs. This application proposes a method and system for statistical analysis of viewership data based on a directed acyclic graph (DAG). In some embodiments, multiple playback device nodes exist within the DAG blockchain, forming a DAG blockchain topology. Each playback device node includes at least a data acquisition module, a data storage module, a data processing module, and an input module, each responsible for collecting, storing, processing, and inputting viewership data into the blockchain.

[0073] Based on this, the exemplary application of the embodiments of this application in a practical application scenario will be described below.

[0074] Figure 5 This is a schematic diagram of viewership data information provided in an embodiment of this application, such as... Figure 5 As shown, the data acquisition module obtains the device information of the first playback device. The device information includes the device type and MAC address, the timestamp of each first program, and the program information of the first program. The program information includes the program name, program duration, program author (an example of a cast and crew member), and key video frame segments of the program, wherein the video frame segments are saved in the form of images.

[0075] In some embodiments, after the data acquisition module completes the collection of viewing data information, it stores it in the data storage module.

[0076] In some embodiments, the data processing module is responsible for processing the viewership data of the first program and determining whether the viewership data meets the statistical requirements based on preset conditions.

[0077] In some embodiments, the blockchain module performs a blockchain entry operation based on the processing results of the viewing data by the data processing module after the viewing data is successfully verified (for example, the similarity between the playback data of the first program and the reference data meets a first threshold). The blockchain module also synchronizes the viewing data information of the first program with other playback device nodes on the blockchain for accounting purposes, thereby preventing the viewing data information from being tampered with.

[0078] Figure 6 This is a schematic diagram of the viewing data information processing flow provided in the embodiments of this application, such as... Figure 6As shown, the acquisition module packages and compresses the viewership data of the first program and stores it in the data storage module. The data storage module is responsible for storing the viewership data written by the acquisition module and marking it as either processed or unprocessed. Viewership data just written by the acquisition module is marked as unprocessed, while data processed by the processing module is marked as processed. When unprocessed data is stored, the data storage module sends a data processing request signal to the processing module, requesting processing. The processing module processes the unprocessed data before storing it in the data storage module. After successful acceptance of the viewership data, the processing module notifies the input module to perform the input operation.

[0079] In some embodiments, the viewing data is processed, namely, at least one frame of the playback image in the playback data of the first program is hashed, and it is determined whether the similarity between the playback image and the corresponding reference image meets a first threshold.

[0080] In some embodiments, after receiving a data processing request signal from the storage module, the data processing module reads the playback data of the first program from the storage module and performs hash processing on the playback image in the playback data to obtain a first hash value. The first playback device node broadcasts the program name of the first program and the time location information of the playback image, requesting the third playback device node on the blockchain to assist in providing the hash value of the reference image at the corresponding time in the first program for viewing data acceptance. After receiving the second hash value of the reference image, the data processing module calculates the image similarity between it and the first hash value of the corresponding playback image. The similarity calculation of the two hash values ​​can use a Hamming distance meter. Within the data processing module, a preset threshold μ is used. If d(x,y)≤μ, it indicates that the similarity between the playback data and the reference data meets the first condition, that is, the viewing data acceptance is successful.

[0081] In some embodiments, the data processing module calculates the hash value of the played image and the corresponding reference image using Hamming distance. After determining that the viewing data acceptance is successful, it notifies the blockchain module to perform the blockchain entry operation, adding the first playback device to the directed acyclic graph blockchain network.

[0082] In some embodiments, such as Figure 2 As shown, when the first first playback device node 1 joins the chain, it confirms the transaction with genesis device node 1 and genesis device node 2. When the second first playback device node 2 joins the chain, it confirms the transaction with genesis device node 2 and first playback node 1. And so on, until the qth first playback device node is added to the directed acyclic graph.

[0083] In some embodiments, nodes in a directed acyclic graph blockchain topology can be other device types, such as program servers.

[0084] This application provides a method and system for statistical analysis of viewership data based on a directed acyclic graph (DAG). The DAG technology is used in the statistical analysis of viewership data such as ratings. The playback device is divided into a collection module, a storage module, a processing module, and an input module. After the processing module successfully verifies the viewership data, the input module packages the viewership data and adds it to the DAG blockchain network.

[0085] The embodiments of this application increase the number of statistical samples, enhance the accuracy and security of statistical data, and prevent viewership data from being tampered with.

[0086] Figure 7 This is another schematic diagram of a blockchain network topology provided in this application embodiment. In the directed acyclic graph blockchain used in this embodiment, since there are no miners, no transaction fees are required, and the playback device node transacts with some device nodes on the blockchain, without the need for... Figure 7 Unlike traditional blockchains that require all nodes to participate in transactions, blockchains can significantly reduce power consumption during the process of acquiring the right to record transactions by eliminating large-scale transactions between all nodes and eliminating transaction fees.
