[0085] See Figure 1 ,Figure 1 FIG. Figure 1 is a schematic structural diagram of a media recommendation information presentation system 100 provided by an embodiment of the present application. To support an exemplary application, the media recommendation information presentation system includes a first terminal 400-1, a second terminal 400-2, and a server 200. The first terminal 400-1, the second terminal 400-2, and the server 200 are connected through a network 300. The network 300 can be a wide area network, a local area network, or a combination of both.

[0086] Among them, the first terminal 400-1 is used for recommending media recommendation information, such as billboards in shopping malls, advertising devices in elevators, roadside billboards, restaurant dish recommendation signs, housing resource recommendation signs, etc.; the second terminal 400-2 is a user handheld terminal, such as a smart phone, a smart watch, a tablet computer, etc.

[0087] In an exemplary scenario, media recommendation information is presented through the first terminal 400-1; the user holds the second terminal 400-2 and moves in the shopping mall. The first terminal 400-1 obtains the location information of the second terminal from the second terminal through a communication connection established with the second terminal, and determines the distance between the second terminal 400-2 and the first terminal 400-1; when the distance between the second terminal 400-2 and the first terminal 400-1 is less than a distance threshold, a request for obtaining media recommendation information is sent to the server 200;

[0088] Based on the acquisition request, the server 200 searches for target media recommendation information suitable for the user corresponding to the second terminal 400-2 and returns it to the first terminal 400-1;

[0089] After receiving the target media recommendation information suitable for the user corresponding to the second terminal 400-2, when the media recommendation information currently presented by the first terminal is not suitable for the user, the first terminal 400-1 cancels the currently presented media recommendation information and presents the target media recommendation information suitable for the user corresponding to the second terminal 400-2.

[0090] In some embodiments, the server 200 can be an independent physical server, or a server cluster or distributed system composed of multiple physical servers, or a cloud server that provides basic cloud computing services such as cloud services, cloud databases, cloud computing, cloud functions, cloud storage, network services, cloud communications, middleware services, domain name services, security services, content delivery network (CDN), and big data and artificial intelligence platforms. The terminal and the server can be directly or indirectly connected through wired or wireless communication methods, which are not limited in the embodiments of the present application.

[0091] Based on the above description of the media recommendation information presentation system of the embodiments of the present application, the media recommendation information presentation method provided by the embodiments of the present application will be described next. In some embodiments, the media recommendation information presentation method provided by the embodiments of the present application can be implemented by the terminal alone, or jointly implemented by the server and the terminal. The media recommendation information presentation method provided by the embodiments of the present application will be described below taking the terminal implementation as an example.

[0092] See Figure 2 , Figure 2 which is a schematic flowchart of the media recommendation information presentation method provided by the embodiments of the present application, and will be described in combination with Figure 2 the steps shown.

[0093] Step 201: Present media recommendation information through the first terminal.

[0094] In actual implementation, the first terminal is used for the recommendation of media recommendation information. Among them, a client is set on the first terminal, such as a video client, a picture client, a news client, etc. The terminal can implement the recommendation of media recommendation information through the client, such as picture information, article information, video information, etc.

[0095] Step 202: When the distance between the second terminal and the first terminal is less than the distance threshold, obtain target media recommendation information adapted to the user corresponding to the second terminal.

[0096] In practical applications, the user can hold the second terminal and move. During the movement, when the distance between the second terminal and the first terminal is less than the distance threshold, the first terminal will obtain target media recommendation information adapted to the user corresponding to the second terminal; for example, when the distance threshold is 1 meter, when the user holds the second terminal and moves to the area within 1 meter of the billboard, it is determined that the distance between the second terminal and the first terminal is less than the distance threshold.

[0097] In some embodiments, the first terminal can determine the distance between the second terminal and the first terminal in the following manner: through the communication connection established with the second terminal, obtain the location information of the second terminal from the second terminal; and determine the distance between the second terminal and the first terminal according to the location information of the second terminal.

[0098] Here, when a communication connection is established between a first terminal and a second terminal, the first terminal can obtain data in the second terminal. In actual implementation, the second terminal obtains its own location information in real time, such as obtaining its own location information through the Global Positioning System (GPS), and sends its own location information to the first terminal in real time. The first terminal monitors the distance between the second terminal and the first terminal in real time based on the obtained location information of the second terminal and its own location information, and compares the distance between the second terminal and the first terminal with a distance threshold. When it is detected that the distance between the second terminal and the first terminal is less than the distance threshold, target media recommendation information suitable for the user corresponding to the second terminal is obtained.

[0099] As an example, the first terminal is a billboard in a shopping mall that provides free WiFi (mobile hotspot) service. When the user's handheld second terminal connects to the free WiFi provided by the first terminal, a communication connection is established between the billboard and the second terminal, and the billboard can obtain data of the second terminal, such as the location information of the second terminal; through the established communication connection with the second terminal, the billboard obtains the location information of the second terminal in real time to determine the distance between the second terminal and the billboard, and compares the determined distance with the distance threshold to determine whether the distance between the second terminal and the first terminal is less than the distance threshold.

[0100] In some embodiments, the first terminal can obtain target media recommendation information suitable for the user corresponding to the second terminal in the following manner: obtain a user profile of the user corresponding to the second terminal; screen out media recommendation information suitable for the user profile from a media information library as target media recommendation information suitable for the user corresponding to the second terminal.

[0101] In actual implementation, the first terminal obtains the basic user information and historical behavior data of the user corresponding to the second terminal. Among them, the basic user information can be information such as the user's gender, age, and income, and the historical behavior data can be search behavior data, browsing behavior data, etc., such as obtaining the information searched by the user during a target time period; then a user profile is constructed according to the basic user information and historical behavior data of the user; after constructing the user profile, the user profile is matched with the media recommendation information in the media information library to screen out media recommendation information suitable for the user profile as target media recommendation information suitable for the user corresponding to the second terminal.

[0102] In some embodiments, the first terminal may screen out media recommendation information adapted to the user profile from the media information library in the following manner: obtain the media tags of each media recommendation information in the media information library; screen out, from the media recommendation information library, the media recommendation information whose media tags match the user interest tags included in the user profile as the media recommendation information adapted to the user profile.

[0103] Here, when the media recommendation information is uploaded to the media information library, media tags will be assigned to the media recommendation information according to its content. The media tags here can be manually labeled or obtained by identifying the media recommendation information and labeling it according to the recognition result; correspondingly, the user profile can be composed of one or more user interest tags.

[0104] In actual implementation, the first terminal obtains the media tags of each media recommendation information in the media information library, then matches the media tags of each media recommendation information with the user interest tags to obtain the matching degree between the media tags of each media recommendation information and the user interest tags; then, based on the obtained matching degree, screen out, from the media information library, the media recommendation information whose media tags match the user interest tags included in the user profile.

[0105] Here, a matching degree threshold can be set. If the matching degree between the media tags of a certain media recommendation information and the user interest tags reaches the matching degree threshold, it is considered that the media tags of this media recommendation information match the user interest tags; or, a preset number of media recommendation information can be set, and the media recommendation information can be sorted according to the matching degree from high to low, and then the preset number of media recommendation information with the highest matching degree is selected as the media recommendation information adapted to the user profile.

[0106] In some embodiments, when the number of user interest tags included in the user profile is at least two, for each user interest tag, it is respectively matched with the media tags of each media recommendation information, and then the matching results of multiple user interest tags and media tags are synthesized to determine the final media recommendation information that matches the media interest tags included in the user profile.

[0107] In actual implementation, for a certain media recommendation information, its media tags can be matched with each user interest tag to obtain multiple matching degrees, and the average value of the multiple matching degrees is used to determine whether this media recommendation information is the media recommendation information whose media tags match the user interest tags included in the user profile. If the average value reaches the matching degree threshold, it is determined that this media recommendation information is the media recommendation information whose media tags match the user interest tags included in the user profile.

[0108] In some embodiments, the first terminal may determine that the media tag matches the user interest tag in the following manner: Semantically recognize the user interest tag and the media tags of each media recommendation information respectively to obtain the semantic information of the user interest tag and the semantic information of each media tag; Perform similarity matching on the semantic information of the user interest tag and the semantic information of each media tag to obtain a matching result; When the matching result indicates that the similarity between the semantic information of the user interest tag and the semantic information of the media tag reaches the similarity threshold, it is determined that the media tag matches the user interest tag.

[0109] Here, matching can be performed based on the semantics of the user interest tag and the media tags of each media recommendation information. In actual implementation, for any one of the user interest tag and the media tags of each media recommendation information, first perform word segmentation on the tag, and then construct a neural network model (such as a convolutional neural network model) to obtain the semantic vectors corresponding to each word obtained by word segmentation, and use the semantic vectors to label the semantic information corresponding to the word. After obtaining the semantic information of each word included in a certain tag, integrate these semantic information to obtain the semantic information of the corresponding tag.

[0110] In practical applications, after obtaining the semantic information of the user interest tag and the semantic information of each media tag, calculate the similarity between the semantic information of the user interest tag and the semantic information of each media tag. Here, the similarity can be cosine similarity, Euclidean distance, Pearson correlation coefficient, etc. Here, the similarity is used to represent the matching degree between the semantic information of the user interest tag and the semantic information of each media tag. Furthermore, compare the calculated similarity with the similarity threshold. For any user interest tag and any media tag, if the similarity between the media tag and the user interest tag reaches the similarity threshold, then it can be determined that the media tag matches the user interest tag.

[0111] In some embodiments, the target media recommendation information suitable for the user corresponding to the second terminal may be obtained in the following manner: When the number of second terminals is at least two, obtain the user interest tags of the users corresponding to each second terminal; Perform tag screening on the user interest tags of the users corresponding to each second terminal to obtain target user interest tags; Screen out the media recommendation information suitable for the target interest tags from the media information library as the target media recommendation information suitable for the user corresponding to the second terminal.

[0112] In actual implementation, when the distance between multiple second terminals and the first terminal is less than the distance threshold, the user interest tags of multiple second terminals can be combined to determine the target user interest tags. Among them, the number of determined target user interest tags can be one or multiple, which is not limited here.

[0113] In some embodiments, the user interest tags shared by the users corresponding to multiple second terminals can be used as the target user interest tags. For example, if the number of second terminals is two, and the corresponding users are User A and User B. Among them, the user interest tags of User A include User Interest Tag 1, User Interest Tag 2, and User Interest Tag 3, and the user interest tags of User B include User Interest Tag 1, User Interest Tag 4, and User Interest Tag 5. Then, User Interest Tag 1 can be used as the target user tag.

[0114] In some embodiments, the user interest tag with the largest corresponding number of users can be used as the target user tag. For example, if the number of second terminals is three, and the corresponding users are User A, User B, and User C. Among them, the user interest tags of User A include User Interest Tag 1, User Interest Tag 2, and User Interest Tag 3, the user interest tags of User B include User Interest Tag 1, User Interest Tag 2, and User Interest Tag 4, and the user interest tags of User C include User Interest Tag 1, User Interest Tag 4, and User Interest Tag 5. Then, User Interest Tag 1 can be used as the target user tag.

[0115] In some embodiments, the target media recommendation information can be presented in the following manner: when the number of second terminals is multiple, a target number of second terminals are screened out from the multiple second terminals according to the distance between each second terminal and the first terminal; and the media recommendation information adapted to the users corresponding to the target number of second terminals is obtained.

[0116] In actual implementation, the number of second terminals whose distance from the first terminal meets the distance condition can be multiple. When the number of second terminals is too large, if the target media recommendation information adapted to the users corresponding to all second terminals is obtained, a large amount of computing resources will be required. Here, according to the distance between each second terminal and the first terminal, the second terminals are screened to determine the target number of second terminals closest to the first terminal, and then the media recommendation information adapted to the users corresponding to the target number of second terminals.

[0117] For example, taking the first terminal as a billboard in a shopping mall, the number of second terminals whose distance from the billboard meets the distance condition can be multiple. Here, the target number is determined to be 5. Then, according to the distance between each second terminal and the billboard, the second terminals are sorted from the nearest to the farthest, and then 5 second terminals are screened starting from the first one according to the sorted sequence, and the target media recommendation information adapted to the users corresponding to these 5 second terminals is obtained.

[0118] In practical applications, when the target number is greater than the number of second terminals, the target media recommendation information adapted to the users corresponding to all second terminals can be obtained.

[0119] Step 203: When the media recommendation information currently presented by the first terminal is not suitable for the user, present target media recommendation information through the first terminal.

[0120] Here, after the first terminal obtains the target media recommendation information suitable for the user corresponding to the second terminal, it determines whether the currently presented media recommendation information is suitable for the user corresponding to the second terminal. When it is determined that the currently presented media recommendation information is not suitable for the user corresponding to the second terminal, the target media recommendation information is presented through the first terminal, so that the user holding the second terminal can view the content presented by the first terminal, so as to recommend the target media recommendation information to the user.

[0121] In actual implementation, it is possible to match the currently presented media recommendation information with the obtained target media recommendation information to determine whether the currently presented media recommendation information is suitable for the user; or, the currently presented media recommendation information can be matched with the user portrait of the user to determine whether the currently presented media recommendation information is suitable for the user.

[0122] In some embodiments, the target media recommendation information can be presented in the following manner: when the number of target media recommendation information is at least two, sort the at least two target media recommendation information according to the degree of suitability of each target media recommendation information for the user to obtain a sorting result; present the at least two target media recommendation information through the first terminal according to the sorting result.

[0123] The target media recommendation information presented according to the sorting result here can be all the obtained target media recommendation information presented, or some of the obtained target media recommendation information, such as presenting the target media recommendation information with a target quantity.

[0124] In actual implementation, when determining the target media recommendation information suitable for the user corresponding to the second terminal, the degree of suitability of each media recommendation information in the media information library for the user will be determined to screen out the media recommendation information whose degree of suitability meets the conditions as the target media recommendation information suitable for the user. Here, the number of target media recommendation information suitable for the user corresponding to the second terminal can be at least two, and the at least two target media recommendation information are sorted according to the determined degree of suitability from high to low. For example, they can be sorted from high to low according to the degree of suitability.

[0125] In some embodiments, the at least two target media recommendation information can be sequentially presented through the first terminal according to the sorting result, that is, when presenting the target media recommendation information, first present the target media recommendation information ranked first, and after the first target media recommendation information is presented, then present the next target media recommendation information.

[0126] In actual implementation, when presenting at least two target media recommendation messages through a first terminal, if the target media recommendation message itself has a corresponding presentation duration, such as when the target media recommendation message is a video message, then the target media recommendation message is presented according to its corresponding duration, that is, after the video is played, the next video is played; when the target media recommendation message itself does not have a corresponding presentation duration, a presentation duration can be set in advance. For example, when the target media recommendation message is a picture message, a presentation duration can be set in advance, such as 5 seconds. When the presentation duration of the picture message reaches 5 seconds, the next target media recommendation message is presented.

[0127] For example, Figure 3 is a schematic diagram of the presentation interface of the media recommendation message provided by an embodiment of the present application. Refer to Figure 3 , the first media recommendation message 301 is presented through the view interface of the first terminal. After 3 seconds, it is switched to the second media recommendation message 302. Here, both the first media recommendation message and the second media recommendation message are target media recommendation messages adapted to the user corresponding to the second terminal, and the degree of adaptation between the first media recommendation message and the user is higher than that between the second media recommendation message and the user.

[0128] In some embodiments, a target number of target media recommendation messages can be presented according to the sorting result. Here, when presenting the target number of target media recommendation messages, the presentation position of the target media recommendation message in the view interface corresponds to its position in the sorting result. For example, when sorting from high to low according to the degree of adaptation, then starting from the first position of the target media recommendation message sequence obtained by sorting, a pre-target number of target media recommendation messages are selected and presented in the view interface from top to bottom in sequence.

[0129] In actual implementation, the target number can be set in advance or set by the user. After presenting the target number of target media recommendation messages, the target media recommendation messages can also be switched according to the sorting result. For example, when the target number is 5, the target media recommendation messages ranked 1-5 are presented first, and when a switching instruction is received, the target media recommendation messages ranked 6-10 are presented.

[0130] In some embodiments, the target media recommendation message can be presented in the following manner: in the view interface of the first terminal, the target media recommendation message adapted to the user corresponding to the second terminal and the associated media information different from the target media recommendation message are presented; among them, the presentation form of the target media recommendation message is the target presentation form, and the target presentation form makes the target media recommendation message different from the associated media information.

[0131] Here, the associated media information can be media recommendation information fixedly presented in the view interface of the first terminal, while the target media recommendation information is media recommendation information adapted to the user corresponding to the second terminal and will change according to different users. In actual implementation, the target presentation form can be enlarged presentation, highlighted presentation, etc., as long as the target presentation form is different from the presentation form of the associated media information. The specific target presentation form is not limited here.

[0132] For example, in the scenario of dish recommendation in a restaurant, the first terminal is the terminal located in the restaurant and is used to present the menu in the restaurant. When presenting the menu, the dish information adapted to the user corresponding to the second terminal can be prominently presented. For example, Figure 4 is a schematic diagram of the presentation interface of the media recommendation information provided by an embodiment of the present application. Refer to Figure 4 , in the view interface of the first terminal, the dish information in the restaurant is presented. Among them, the dish information 401 adapted to the user corresponding to the second terminal is presented in the form of a combination of text and pictures and is presented at the top of the view interface, and other dish information 402 is presented in text form to prominently display the dish information adapted to the user corresponding to the second terminal.

[0133] In some embodiments, when the number of second terminals is at least two, correspondingly, the target media recommendation information includes the target media recommendation information adapted to the users corresponding to at least two second terminals; the first terminal can present the target media recommendation information in the following way: in the view interface of the first terminal, at least two presentation areas equal to the number of second terminals are presented, and through the at least two presentation areas, the target media recommendation information adapted to the users corresponding to each second terminal is presented respectively; among them, the presentation areas correspond to the second terminals one by one.

[0134] In actual implementation, the number of second terminals can be at least two. Here, the number of presentation areas in the view interface of the first terminal can be determined according to the number of second terminals so that the number of presentation areas is the same as the number of second terminals. In this way, each area can correspond to a second terminal, and the media recommendation information adapted to the users corresponding to the respective second terminals can be presented through the respective presentation areas.

[0135] For example, when the number of second terminals is 4, Figure 5 is a schematic diagram of the presentation interface of the media recommendation information provided by an embodiment of the present application. Refer to Figure 5, the view interface of the first terminal is divided into 4 presentation areas, namely 501, 502, 503, and 504. Among them, 501 corresponds to the second terminal of user A, 502 corresponds to the second terminal of user B, 503 corresponds to the second terminal of user C, and 504 corresponds to the second terminal of user D. Then, the target media recommendation information adapted to user A is presented through 501, the target media recommendation information adapted to user B is presented through 502, the target media recommendation information adapted to user C is presented through 503, and the target media recommendation information adapted to user D is presented through 504.

[0136] Here, the types of the target media recommendation information presented in each presentation area may be the same or different. For example, when there are two presentation areas in the view interface of the first terminal, both of these two presentation areas may present video information, or one may present video information and the other may present picture information.

[0137] In some embodiments, the target media recommendation information may be presented in the following manner: obtaining the user level of the user corresponding to the second terminal; when the user level reaches the corresponding level threshold, presenting the target media recommendation information adapted to the user corresponding to the second terminal through the first terminal.

[0138] In actual implementation, obtain the user level of the user corresponding to the second terminal, compare the user level with the level threshold, and only recommend personalized media recommendation information for users whose user levels reach the corresponding level thresholds. If the user level does not reach the corresponding level threshold, then no personalized recommendation is made for them.

[0139] For example, when the first terminal is a billboard in a shopping mall, some users may just pass by the billboard without purchasing power. Here, the user level of the user corresponding to the second terminal can be obtained to determine whether the user has purchasing power. When the user has purchasing power, personalized advertisement recommendations are made for them, such as only making personalized recommendations for VIP users of the shopping mall.

[0140] In some embodiments, the terminal can also generate a presentation record of the target media recommendation information corresponding to the second terminal; perform a hash transformation on the presentation record to obtain summary information corresponding to the presentation record; and store the summary information in the blockchain network.

[0141] Here, the embodiments of the present application can also be combined with blockchain technology. After presenting the record of the target media recommendation information of the second terminal, a transaction for storing the presentation record of the target media recommendation information corresponding to the second terminal is generated and submitted to the nodes of the blockchain network, so that the nodes store the presentation record of the target media recommendation information corresponding to the second terminal in the blockchain network after reaching a consensus on the transaction; before storing it in the blockchain network, the terminal can also obtain the digest information of the corresponding presentation record for the presentation record of the target media recommendation information corresponding to the second terminal; and store the obtained digest information of the corresponding presentation record in the blockchain network. Through the above method, the presentation record is prevented from being tampered with, and the security of the user's presentation record is improved.

[0142] See Figure 6 , Figure 6 FIG. is a schematic diagram of the application architecture of the blockchain network provided by the embodiments of the present application, including a business entity 400, an authentication center 500, and a blockchain network 600 (exemplarily showing consensus nodes 610-1 to 610-3). The following will be described separately.

[0143] The type of the blockchain network 600 is flexible and diverse. For example, it can be any one of a public chain, a private chain, or a consortium chain. Taking the public chain as an example, the electronic devices of any business entity, such as user terminals and servers, can access the blockchain network 600 without authorization; taking the consortium chain as an example, the computer devices (such as terminals / servers) under the jurisdiction of the business entity can access the blockchain network 600 after obtaining authorization. At this time, they become client nodes in the blockchain network 600.

[0144] In some embodiments, the client node can only be an observer of the blockchain network 600, that is, it provides functions to support the business entity to initiate transactions (for example, for storing data on the chain or querying data on the chain). For the functions of the consensus nodes 610 of the blockchain network 600, such as sorting functions, consensus services, and ledger functions, etc., the client node can be default or selectively (for example, depending on the specific business needs of the business entity) implemented. Thus, the data and business processing logic of the business entity can be migrated to the blockchain network 600 to the greatest extent, and the trust and traceability of the data and business processing process can be achieved through the blockchain network 600.

[0145] The consensus nodes in the blockchain network 600 receive the transactions submitted by the client nodes of the business entity 400, execute the transactions to update the ledger or query the ledger, and various intermediate results or final results of the executed transactions can be returned to the client nodes of the business entity for display.

[0146] For example, the client node 410 can subscribe to events of interest in the blockchain network 600, such as transactions occurring in a specific organization / channel in the blockchain network 600. The consensus node 610 pushes the corresponding transaction notification to the client node 410, thereby triggering the corresponding business logic in the client node 410.

[0147] Taking the access of a business entity to the blockchain network to realize the redemption of points as an example, the exemplary application of the blockchain is described below.

[0148] See Figure 6 , the business entity 400 involved in the presentation of the target media recommendation information registers and obtains a digital certificate from the certification center 500. The digital certificate includes the public key of the business entity and the digital signature signed by the certification center 500 for the public key and identity information of the business entity. It is used to be attached to the transaction together with the digital signature of the business entity for the transaction and sent to the blockchain network, so that the blockchain network can extract the digital certificate and signature from the transaction to verify the reliability of the message (i.e., whether it has been tampered with) and the identity information of the business entity sending the message. The blockchain network will perform verification based on the identity, such as whether it has the permission to initiate the transaction. The client running on the computer device (such as a terminal or a server) under the business entity can request access to the blockchain network 600 and become a client node.

[0149] The client node 410 of the business entity 400 is used to present the target media recommendation information. For example, when the distance between the second terminal and the first terminal meets the distance condition, it obtains the target media recommendation information suitable for the user corresponding to the second terminal; presents the target media recommendation information suitable for the user corresponding to the second terminal through the first terminal; generates a presentation record of the target media recommendation information corresponding to the second terminal; and sends the presentation record to the blockchain network 600.

[0150] Among them, for the operation of sending the presentation record to the blockchain network 600, the business logic can be pre-set in the client node 410. When the presentation record of the target media recommendation information corresponding to the second terminal is generated, the client node 410 automatically sends the presentation record to the blockchain network 600. It can also be that the business personnel of the business entity 400 log in to the client node 410, manually package the redemption record, and send it to the blockchain network 600. When sending, the client node 410 generates a transaction corresponding to the storage operation according to the presentation record of the target media recommendation information corresponding to the second terminal. The transaction specifies the smart contract to be called to implement the storage operation and the parameters passed to the smart contract. The transaction also carries the digital certificate and the signed digital signature of the client node 410 (for example, encrypted using the private key in the digital certificate of the client node 410 for the digest of the transaction), and broadcasts the transaction to the consensus node 610 in the blockchain network 600.

[0151] When the consensus node 610 in the blockchain network 600 receives a transaction, it verifies the digital certificate and digital signature carried by the transaction. After successful verification, it confirms whether the business entity 400 has transaction authority based on the identity of the business entity 400 carried in the transaction. Any verification failure in the digital signature and authority verification will result in the failure of the transaction. After successful verification, the signing node 610 signs its own digital signature (for example, encrypts the digest of the transaction using the private key of node 610-1) and continues to broadcast in the blockchain network 600.

[0152] After the consensus node 610 in the blockchain network 600 receives a transaction with successful verification, it fills the transaction into a new block and broadcasts it. When the consensus node 610 in the blockchain network 600 broadcasts a new block, it conducts a consensus process on the new block. If the consensus is successful, it appends the new block to the tail of the blockchain stored by itself and updates the state database according to the result of the transaction, and executes the transaction in the new block: for the transaction submitting an update to the collection record, it adds a collection record to the state database.

[0153] As an example of the blockchain, see Figure 7 , Figure 7 which is a schematic structural diagram of the blockchain in the blockchain network 600 provided by the embodiment of the present application. The header of each block can include both the hash value of all transactions in the block and the hash value of all transactions in the previous block. After the record of the newly generated transaction is filled into the block and consensus is reached among the nodes in the blockchain network, it will be appended to the tail of the blockchain to form a chain-like growth. The chain-like structure based on the hash value between blocks ensures the anti-tampering and anti-counterfeiting of the transactions in the block.

[0154] The following describes the exemplary functional architecture of the blockchain network provided by the embodiment of the present application. See Figure 8 , Figure 8 which is a schematic diagram of the functional architecture of the blockchain network 600 provided by the embodiment of the present application. The blockchain network includes an application layer 601, a consensus layer 602, a network layer 603, a data layer 604, and a resource layer 605, which will be described separately below.

[0155] The resource layer 605 encapsulates the computing resources, storage resources, and communication resources of each node 610 in the blockchain network 600.

[0156] The data layer 604 encapsulates various data structures for implementing the ledger, including the blockchain implemented as files in the file system, the key-value state database, and the proof of existence (such as the hash tree of the transactions in the block).

[0157] The network layer 603 encapsulates functions such as the point-to-point (P2P) network protocol, data dissemination mechanism, data verification mechanism, access authentication mechanism, and business entity identity management.

[0158] Among them, the P2P network protocol enables communication between nodes 610 in the blockchain network 600. The data dissemination mechanism ensures the dissemination of transactions in the blockchain network 600. The data verification mechanism is used to achieve the reliability of data transmission between nodes 610 based on cryptographic methods (such as digital certificates, digital signatures, public / private key pairs). The access authentication mechanism is used to authenticate the identity of business entities joining the blockchain network 600 according to the actual business scenario and grant the business entity the permission to access the blockchain network 600 when the authentication is passed. The business entity identity management is used to store the identities of business entities allowed to access the blockchain network 600 and their permissions (such as the types of transactions that can be initiated).

[0159] The consensus layer 602 encapsulates the mechanism for nodes 610 in the blockchain network 600 to reach consensus on blocks (i.e., the consensus mechanism), as well as functions for transaction management and ledger management. The consensus mechanism includes consensus algorithms such as POS, POW, and DPOS, and supports the pluggability of consensus algorithms.

[0160] Transaction management is used to verify the digital signatures carried in the transactions received by nodes 610, verify the identity information of business entities, and determine whether they have the permission to conduct transactions based on the identity information (reading relevant information from the business entity identity management). For business entities authorized to access the blockchain network 600, they all have digital certificates issued by the certification authority. The business entity uses the private key in its digital certificate to sign the submitted transaction, thereby declaring its legal identity.

[0161] Ledger management is used to maintain the blockchain and the state database. For the blocks that have reached consensus, they are appended to the end of the blockchain. Execute the transactions in the blocks that have reached consensus. When the transaction includes an update operation, update the key-value pairs in the state database. When the transaction includes a query operation, query the key-value pairs in the state database and return the query results to the client node of the business entity. Support various-dimensional query operations on the state database, including: querying blocks according to the block serial number (such as the hash value of the transaction); querying blocks according to the block hash value; querying blocks according to the transaction serial number; querying transactions according to the transaction serial number; querying the account data of business entities according to the account (serial number) of the business entity; querying the blockchain in the channel according to the channel name.

[0162] The application layer 601 encapsulates various services that the blockchain network can implement, including transaction traceability, evidence storage, and verification, etc.

[0163] Applying the above embodiments, media recommendation information is presented through a first terminal; when the distance between the second terminal and the first terminal meets the distance condition, target media recommendation information adapted to the user corresponding to the second terminal is obtained; when the media recommendation information currently presented by the first terminal is not adapted to the user, the target media recommendation information is presented through the first terminal; thus, when the second terminal is near the first terminal, the first terminal can present the target media recommendation information adapted to the user corresponding to the second terminal, so that the target media recommendation information presented by the first terminal is adapted to the users near it, thereby improving the effectiveness of presenting media recommendation information.

[0164] The following continues to describe the method for presenting media recommendation information provided by the embodiments of the present application. In some embodiments, the method for presenting media recommendation information provided by the embodiments of the present application can be jointly implemented by a first terminal, a second terminal, and a server.

[0165] Figure 9 It is a flowchart of the method for presenting media recommendation information provided by the embodiments of the present application. Refer to Figure 9 , the method for presenting media recommendation information provided by the embodiments of the present application includes:

[0166] Step 901: The server obtains the location information of the first terminal and the second terminal.

[0167] Step 902: The server determines the distance between the second terminal and the first terminal according to the location information of the first terminal and the second terminal.

[0168] Step 903: When the distance between the second terminal and the first terminal is less than the distance threshold, the server sends a request for obtaining user information to the second terminal.

[0169] Step 904: The second terminal sends the basic information and historical behavior data of the user to the server.

[0170] Step 905: The server constructs a user profile according to the basic information and historical behavior data of the user.

[0171] Step 906: The server screens out target media recommendation information adapted to the user profile from the media information library and sends it to the first terminal.

[0172] Step 907: The first terminal switches the currently presented media recommendation information to the target media recommendation information.

[0173] Applying the above embodiments, when the second terminal is near the first terminal, the server can screen out target media recommendation information according to the user profile of the user corresponding to the second terminal and send it to the first terminal, so that the first terminal can switch the currently presented media recommendation information to the target media recommendation information adapted to the users near it, thereby improving the effectiveness of the presentation of media recommendation information.

[0174] The following will illustrate the exemplary application of the embodiments of the present application in an actual application scenario. Taking the first terminal as a billboard as an example to illustrate the method for presenting media recommendation information provided by the embodiments of the present application. Here, the billboard is installed with a video client, and the video client is connected to the second terminal carried by the user through the Internet of Things to obtain data in the second terminal, such as user basic information, user behavior data, etc.

[0175] Among them, the networking technologies of the Internet of Things are much richer than those of the Internet technology. On the one hand, it inherits the Internet networking technology, and on the other hand, due to the particularity of the Internet of Things environment and devices, many suitable networking technologies have emerged. The following figure shows the networking technologies used in a typical Internet of Things scenario.

[0176] Figure 10 is a schematic diagram of the Internet of Things connection provided by the embodiments of the present application. Refer to Figure 10 , in the Internet of Things scenario, each device or host is connected to the Internet of Things network in a certain way, such as through Ethernet, Bluetooth, RS485 bus, WiFi, LaRa, Zigbee.

[0177] In actual implementation, the connection forms can usually be divided into wired connections and wireless connections. Different types of devices may choose different connection methods, and finally form an interconnected network. The following will illustrate the common connection methods.

[0178] 1) Ethernet: Ethernet is the most commonly used local area network networking method (the main standard is IEEE 802.3). A network is formed through hubs, switches, and routers, and these network devices are connected to the host using twisted pairs (or optical fibers). Figure 11 is a schematic diagram of Ethernet-connected devices provided by the embodiments of the present application. Refer to Figure 11 , the Ethernet-connected devices include connecting wires, hubs, switches, and routers. Figure 12 is a schematic diagram of the Ethernet networking structure provided by the embodiments of the present application. Refer to Figure 12 , the terminal is connected to the switch, the switch is connected to the router, and then connected to the Internet through the router.

[0179] 2) WIFI: WIFI represents the wireless local area network networking technology (the main standard is IEEE 802.11), which is widely used in home, commercial and industrial scenarios and has become one of the most mainstream networking methods. WIFI provides great convenience for networking within a building, avoiding physical wiring and construction. At the same time, the range of the WIFI network can be as small as a single room or as large as a town level, and the bandwidth can range from dozens of Mbps to hundreds of Mbps. Figures 13A - 13B It is a schematic diagram of the WiFi networking structure provided by the embodiments of this application. Refer to Figure 13A , in a relatively small space, all networked devices can be connected by a single wireless router; if the signal is weak due to encountering a wall, or the signal is weak in a slightly larger area, a signal amplifier or a cascaded connection of multiple wireless routers can be added to form a network; refer to Figure 13B , in a relatively large space, such as an office space across floors, a combination of an access controller (AC, Access Controller) and wireless access points (APs, AccessPoints) can be used to form a wireless local area network. These APs are connected by wire, so that the space is not affected by the wireless transmission distance, and the wireless connection of users can roam throughout the area.

[0180] 3) Bluetooth: Bluetooth is a short-range (usually less than 10 meters) wireless communication technology, which is usually used for data communication between laptop computers, smartphones, in-vehicle systems, wireless earphones, and various wearable devices. The characteristics of Bluetooth are: short range, low power consumption, and low rate, which are suitable for building a personal area network (PAN, Personal Area Network) in a small area. Bluetooth operates in the globally available 2.4GHz unlicensed band and uses the IEEE 802.11 protocol. In addition to being widely used in personal wearables and consumer computer devices, Bluetooth technology is also used in industries, medical, automotive and other fields to provide convenience for device networking and diagnosis. However, many problems have been encountered in the development of Bluetooth technology, including power consumption, transmission security, and cumbersome connection. With the development of Bluetooth technology to version 4.0 (in 2012), these problems have been greatly improved and are currently very popular. Bluetooth devices usually cannot directly connect to the Internet, but can connect to the Internet with the help of other devices. Figures 14A - 14C It is a schematic diagram of the Bluetooth networking structure provided by the embodiments of this application. Refer to Figure 14A , smart bracelets and watches are connected to the Internet through smartphones or tablets (up to 7 can be connected at the same time); refer to Figure 14B , multiple Bluetooth devices are connected to the Internet through a Bluetooth router; Bluetooth 5.0 supports Bluetooth Mesh, which forms an ad-hoc network in a mesh structure and is suitable for networking in scenarios with a dense concentration of Bluetooth devices. Refer toFigure 14C , a Bluetooth Mesh network is constructed using indoor lighting nodes, and other Bluetooth devices join this network.

[0181] 4) Low Power Wide Area Network (LPWAN): LPWAN is suitable for enabling Internet of Things (IoT) terminals to connect to the Internet within a wide area. There are typically two technologies: NB-IoT and LoRa. a. NB-IoT is a narrowband low-power wide area network technology that uses mobile base stations for communication. It uses licensed frequency bands and can be directly deployed on existing mobile communication networks, requiring the operator to provide services and support. NB-IoT targets IoT devices with low power consumption, wide area coverage, small data volume, and low update frequency, and is suitable for various outdoor scenarios such as street lights, parking, shared bicycles, logistics containers, and air monitors. Figures 15A - 15B It is a schematic diagram of the LPWAN networking structure provided by an embodiment of this application. Figure 15A It shows a typical NB-IoT network structure; Figure 15B It shows the LoRa network structure. LoRa is another narrowband communication technology that competes with NB-IoT and uses unlicensed frequency bands. When networking with LoRa, it does not require operator support. The terminal device connects to the local area network or the Internet through a LoRa gateway. LoRa can be used by enterprises to establish a wide-area private wireless network to connect various IoT devices in the enterprise scenario, and the distance between the device and the gateway can reach 2 kilometers to more than 10 kilometers.

[0182] 5) Zigbee: Zigbee is a short-range (10 meters to nearly 100 meters) wireless network technology suitable for connecting terminal devices in an indoor environment. The lower layer protocol of the Zigbee network complies with the IEEE 802.15.4 standard, and the upper layer protocol is defined and standardized by the Zigbee organization, achieving transmission security and the communication requirements of the application layer between nodes. The Zigbee networking cost is low. A network is constructed through a coordinator. The terminal device either communicates directly with the coordinator or indirectly connects to the network through other devices in a relay manner. Zigbee is currently mainly applied to scenarios with a large number of networked devices such as industrial automation, building automation, warehousing and logistics, and smart homes. Figure 16 It is a schematic diagram of the Zigbee networking structure provided by an embodiment of this application. Refer to Figure 16 , smart lights, thermometers, and air detectors are Zigbee terminal devices. Some devices are connected to the network through Zigbee repeaters and finally connect to the Internet through the Zigbee coordinator.

[0183] 6) DALI (Digital Addressable Lighting Interface): DALI is an open standard in the field of intelligent lighting. DALI is used to connect lighting devices. Each DALI bus can connect 64 lighting or switch devices, and the length can reach 300 meters. The DALI standard defines the communication language between devices: turn on, turn off, adjust the light, etc. The DALI controller, as a gateway, can be connected to RS-232, RS-485, Ethernet, or directly connected to wireless WIFI or mobile communication networks. Figure 17 is a schematic diagram of the DALI networking structure provided by the embodiments of the present application. Refer to Figure 17 , the terminal is connected to the DALI controller through the DALI bus and then connected to the Internet through the controller.

[0184] 7) Satellite networking: Connecting to the network through satellites is a relatively convenient way under special conditions, such as on airplanes, in remote mountainous areas, or on the sea. Communication satellites are connected to the Internet through ground stations. Figure 18 is a schematic diagram of the satellite networking structure provided by the embodiments of the present application. Refer to Figure 18 , satellite phones or ground receiving stations are connected to communication satellites through satellite antennas, and then connected to Internet services. In addition to data communication, current mainstream outdoor positioning is also achieved through satellites, such as the commonly used GPS positioning and Beidou satellite positioning.

[0185] Devices are connected to the network through the above various forms, usually connected to the IP network, and become part of the local area network or the Internet. Among them, the gateway is a key device, which can connect the independently organized Internet of Things network to the Internet. In the related art, there is a special intelligent gateway device (also known as the Internet of Things gateway), which can adapt to most common Internet of Things networking methods and organize Internet of Things devices with different connection methods into a network. Figure 19 is a schematic diagram of the intelligent gateway device provided by the embodiments of the present application. Refer to Figure 19 , the intelligent gateway can connect sub-networks such as RS-485, Ethernet, WIFI, and Zigbee.

[0186] In some cases, a PC (especially an industrial control PC) can also act as a gateway, usually supporting Ethernet, RS-232, and USB interfaces, and connecting to the RS-485 bus network through the RS-232 or USB to transfer the RS-485 interface.

[0187] Next, taking the WiFi connection method as an example, the method for presenting media recommendation information provided by the embodiments of the present application will be described. Figure 20It is a schematic flowchart of a method for presenting media recommendation information provided by an embodiment of the present application. Refer to Figure 20 The method for presenting media recommendation information provided by an embodiment of the present application includes:

[0188] Step 1901: The video client obtains the location information of the user terminal through the Internet of Things.

[0189] In actual implementation, the billboard provides free WiFi service and is installed with a video client. When the user terminal connects to the free WiFi provided by the billboard, the billboard establishes an Internet of Things connection with the user terminal, and the video client can obtain the data on the user terminal through the Internet of Things.

[0190] Step 1902: When it is determined that the distance between the user terminal and the billboard is less than the distance threshold according to the location information of the user terminal, obtain user information from the user terminal.

[0191] Here, during the process of the user moving with the user terminal, when the distance between the user terminal and the billboard is less than the distance threshold, that is, when the user moves near the billboard, the video client obtains user information from the user terminal. The user information here may include basic user information such as age and gender, and may also include user behavior data such as user browsing information and user search information.

[0192] Step 1903: The video client sends the user information to the advertising cloud service.

[0193] Step 1904: The advertising cloud service calls the user profiling service to construct user interest tags according to the user information.

[0194] Step 1905: Screen out the advertisements in the advertisement library that are adapted to the user interest tags according to the user interest tags.

[0195] In actual implementation, when the advertisement is placed, an advertisement tag is added to the advertisement for matching with the user interest tag.
