The embodiments of the present application will be described below with reference to the drawings.
Referring to fig. 2, fig. 2 is a schematic flowchart illustrating an advertisement frequency control method according to an embodiment of the present application. The method can comprise the following steps:
201. the user node acquires the generated advertisement exposure information, wherein the advertisement exposure information comprises an advertisement identifier, an advertisement position, exposure time, a delivery source node and an advertisement main node of the target advertisement.
The data sharing system involved in the embodiment of the present application may be the above-mentioned blockchain system, and data sharing and processing in the data sharing system may be implemented based on the blockchain. The delivery system related to the embodiment of the application refers to a system for delivering advertisements to users in a network media platform, belongs to a node in a block chain network, can be understood as a server on a media side, and delivers advertisements to user nodes in the block chain network.
The execution subject in the embodiment of the present application may be the user node, for example, a terminal used by a user side, and may receive and output the advertisement from the delivery node through a client. In particular implementations, the above-described terminals may also be referred to as terminal devices, including but not limited to other portable devices such as mobile phones, laptop computers, or tablet computers having touch-sensitive surfaces (e.g., touch screen displays and/or touch pads), which may implement location services and navigation functions through application programs. It should also be understood that in some embodiments, the devices described above are not portable communication devices, but rather are desktop computers having touch-sensitive surfaces (e.g., touch screen displays and/or touch pads).
The method in the embodiment of the application can be applied to an advertisement frequency control system, specifically, the advertisement frequency control system can comprise a plurality of delivery nodes, user nodes and advertisement main nodes, and any one user node is taken as an example for explanation in the embodiment of the application. The advertisement exposure information may be generated by an application program or a plug-in of a user node, and generally, when advertisement exposure occurs, corresponding advertisement exposure information is generated, and for convenience of statistics, control and optimization of a delivery node, the advertisement exposure information is sent to a server delivering the advertisement and a third-party detection system in the form of an exposure request. The advertisement exposure information comprises an advertisement identification, an advertisement position, exposure time, a delivery source node and an advertisement main node of a target advertisement, the target advertisement is the advertisement of the current exposure, the advertisement identification can be a name, a code or a character string, the advertisement position refers to an area position where the advertisement exposure is displayed, specifically can be an advertisement position number or a character string, and each advertisement position can only display one advertisement at the same time. The serving source node is a serving node that serves to serve the target advertisement to the user node, and may specifically be a serving source node address.
However, in order to further improve the accuracy of the exposure information, it is avoided that some background programs or plug-ins generate false advertisement exposure information at the user node to increase the exposure amount, and the authenticity of the advertisement exposure information can be verified before recording, that is, step 202 is executed.
202. The user node acquires a first key used for exposure verification by the release source node; and the user node acquires a second key used for exposure verification by the advertising main node.
After the user node determines the addresses of the advertisement exposure information, the first key used by the advertisement exposure source node for exposure verification and the second key used by the advertisement host node for exposure verification may be obtained. Namely, the user node can verify the target advertisement delivery node and the advertisement host node recorded in the advertisement exposure information and determine the authenticity of the target advertisement.
In one embodiment, some of the advertisement data or information may be encrypted and decrypted in block chains based on a form of Public Key and private Key (PrivateKey). The public key and the private key are a key pair (i.e. a public key and a private key) obtained through an algorithm, the public key is a public part of the key pair, and the private key is a non-public part. The public key is typically used to encrypt session keys, verify digital signatures, or encrypt data that can be decrypted with a corresponding private key. The key pair derived by such an algorithm is guaranteed to be unique worldwide. When using this key pair, if one of the keys is used to encrypt a piece of data, the other key must be used to decrypt the piece of data. For example, encrypting data with a public key necessitates decryption with the private key, and if encrypting with the private key, also must decrypt with the public key, otherwise decryption will not succeed.
The first key and the second key may be public keys of the advertisement exposure information describing the advertisement exposure source node and the advertisement master node, respectively, and all nodes in the blockchain may be queried and used. The digital signature of the target advertisement in the advertisement exposure information can be parsed through the first key and the second key for verification, i.e. step 203 is executed.
It should be appreciated that since the blockchain is a decentralized, distributed database, each time data is processed, one of the servers in the blockchain network needs to be selected as an executor to process the data. The rule for selecting the server each time is a Consensus mechanism, which in the embodiment of the present application may be a workload certification mechanism (Proof of Work, POW), an equity certification mechanism (Proof of stamp, POS), a Ripple Consensus mechanism (Ripple Consensus), an authorized equity certification mechanism (DPOS), and the like, and is not limited herein.
203. The user node analyzes a first digital signature of the target advertisement using the first key and a second digital signature of the target advertisement using the second key to determine whether the target advertisement matches the placement source node and the advertiser node.
In a distributed network of a block chain, communication between nodes and trust achievement need to rely on a digital signature technology, and digital signatures relate to tools such as public keys, private keys and wallets, and have two functions: firstly, the message is proved to be actually signed and sent out by the message sender; the second is to determine the integrity of the message.
The digital signature technique is to encrypt the digest information with the sender's private key and transmit it to the receiver together with the original text. The receiver can decrypt the encrypted digest information only with the sender's public key, and then generates a digest information for the received original text using a HASH (HASH) function, which is compared with the decrypted digest information. If the information is the same as the received information, the received information is complete and is not modified in the transmission process, otherwise, the information is modified. The digital signature is able to verify the integrity of the information.
Similarly, the exposed target advertisement recorded in the advertisement exposure information contains a digital signature of a delivery node, i.e. a first digital signature, and a digital signature of the advertiser node, i.e. a second digital signature. In order to verify whether the target advertisement is delivered after being confirmed by the corresponding advertisement main node and the delivery node and avoid false advertisement exposure, the first digital signature of the target advertisement can be analyzed through the acquired first key, and the second digital signature of the target advertisement is analyzed by using the second key so as to confirm whether the advertisement exposure information is true and accurate.
Specifically, the user node can firstly use the private key of the user node to unlock a ciphertext corresponding to the target advertisement, and obtains an abstract through hash operation; and analyzing the corresponding digital signature through the acquired public keys of the advertising main node and the launching node to obtain an abstract, respectively comparing the abstract of the decrypted ciphertext with the abstract of the decrypted digital signature, if the abstracts are consistent, determining that the target advertisement is matched with the launching source node and the advertising main node, namely determining that the exposed advertisement is entrusted to the advertising main node and launched by the launching node, and recording the accurate and effective advertisement exposure information to execute the step 204. If the abstracts are not completely consistent, the target advertisement is determined to be not matched with the delivery source node and the advertisement main node, that is, the advertisement of the current exposure is determined not to be delivered by the advertisement main node entrusted and the delivery node, the advertisement exposure information is invalid, and the step 204 is not executed.
204. If the target advertisement is matched with the delivery source node and the advertisement main node, the user node generates a target block to record the advertisement exposure information and a corresponding user node identifier, and stores the target block in a data sharing system.
And performing signature verification on the generated advertisement exposure information to determine the true delivery source node and the advertisement main node of the exposure advertisement to be recorded. If the target advertisement is matched with the delivery source node and the advertisement main node, that is, the advertisement exposure information is accurate and real, the target block can be generated to record the advertisement exposure information, and the user node identifier can be recorded at the same time. An advertisement main node in the block chain network entrusts an advertisement putting node to put an advertisement to a user, and corresponding advertisement order information can be generated during entrusting. And the advertising material may be understood as video or pictures that are ultimately presented to the user.
Further, the advertisement exposure information stored in the blockchain may be received and acquired by other nodes in the blockchain, i.e., step 205 may be performed.
205. And under the condition that the generation of the target block is detected, each delivery node acquires the advertisement exposure information and the corresponding user node identification from the target block, and uses the advertisement exposure information for the exposure frequency statistics of the target advertisement.
After step 204, each delivery node in the block chain may receive the generated target block, and obtain the advertisement exposure information and the corresponding user node identifier, so as to know the advertisement exposure condition of the user node, that is, when the target advertisement is exposed, which materials are exposed, and the like, which can be used for the exposure frequency statistics of the target advertisement.
As mentioned above, the advertisement frequency refers to the number of times that an advertiser specifies the exposure of an advertisement to a user in a certain period when placing the advertisement. The exposure frequency of each advertisement is limited, and through the advertisement exposure information provided by the user nodes, each delivery node can adjust the delivery strategy of the user nodes in time, so that the delivery nodes can make an advertisement decision with better user experience, and the user experience is optimized.
Specifically, the exposure frequency of the target advertisement at the user node may be counted according to the advertisement exposure information of the user node;
the method further comprises the following steps: and the advertising strategy of the user nodes is determined by each advertising node according to preset frequency control information and the exposure frequency of the target advertisement at the user nodes.
The preset frequency control information can be provided by an advertisement main node, the advertisement main node can require the preset exposure times of the target advertisement in a certain period to the releasing nodes, each releasing node can release the target advertisement, and the final requirements of the advertisement main node are jointly met in the process.
Optionally, the method further includes: the advertisement main node sends frequency control information to each launching node in the launching node set, wherein the frequency control information comprises an advertisement identifier of a target advertisement, a preset exposure period and a preset exposure frequency of each advertisement in a user node in the exposure period;
and each delivery node performs advertisement delivery operation on the user node according to the frequency control information.
And the cross-platform frequency control of each release node can be realized through the block chain. Specifically, at the advertisement serving node, the advertisement serving node with frequency control has corresponding preset frequency control information, which includes a preset exposure period and preset exposure times of the target advertisement at each user node in the exposure period, so that the exposure condition of the target advertisement can be monitored, and the exposure times of the target advertisement at the user nodes can be periodically counted. And when detecting that the exposure frequency of the target advertisement in a certain user node in the exposure period reaches the preset exposure frequency, stopping delivering the target advertisement to the user node.
In the case that the exposure frequency of the target advertisement at a certain user node in the exposure period does not reach the preset exposure frequency, the delivery strength of the target advertisement at the user node needs to be increased, the number of times of delivering the target advertisement to the user node can be increased, or the form of delivering the target advertisement to the user node is changed, so as to achieve the maximum advertisement delivery frequency, that is, more exposure is obtained within frequency control. Alternatively, the control operation may be set for the shot in the next exposure period.
For example, the advertiser node may delegate the ad placement a to 3 placement nodes A, B, C in the block chain, and set the total frequency to be 2, that is, the exposure of the ad a in each user node does not exceed 2 times within a certain period; platform a achieves that after user node M is exposed once, B, C focuses on that advertisement a has been exposed once at user node M, and should adjust the remaining number of times to 2-1, so as to implement full network frequency control.
In an optional implementation manner, when detecting that the exposure times of the target advertisement at the user node in the exposure period reach the preset exposure times, each delivery node stops delivering the target advertisement to the user node, so as to achieve frequency control in advertisement delivery, control resource cost, that is, not wasting resources and delivering the same advertisement to the user, and improve user experience. That is, when the number of exposures recorded by the user reaches the frequency limit, multiple media should stop delivering the advertisement to the user.
Optionally, the delivery node may also give certain incentive to uplink users, so as to encourage more users to join the blockchain and increase the amount of shared data.
The advertisement data of user node exposure can be completely and accurately recorded through the block chain, each releasing node can obtain the target block, so that the advertisement exposure information is obtained, cross-platform frequency control is realized, namely the exposure data of the media on the user is not singly verified among a plurality of media, meanwhile, the exposure data of the same advertisement on other media needs to be counted, and when the frequency limit set by an advertiser is reached, the advertisement is not released to the user. For the advertisement main node in the block chain, the exposure information of the advertisement put by the main node can be acquired for inquiry, statistics and the like. By the safe, accurate and complete characteristics of the block chain, exposure data can be completely acquired, false exposure is reduced, and therefore more accurate frequency control is achieved. Meanwhile, data does not need to pass through a third-party monitoring system, and interaction and logarithmic errors with third-party monitoring are reduced.
In one embodiment, the blockchain underlying platform may include processing modules for user management, basic services, intelligent contracts, and operation monitoring.
