Background

With the development of internet technology, advertising services have also been rapidly developed. Based on the development of advertisement services, more and more advertisement auction platforms are emerging for processing advertisement information in the advertisement auction process.

The prior art advertisement auction platform is an interactive platform including an advertiser, an advertiser and a third party control end independent of the advertiser and the advertiser, and deploys the processing logic of advertisement information in the advertisement auction process at the third party control end. The method specifically comprises the following steps: firstly, the advertisement auction information of the advertiser is initiated through the third-party control end, and then through the advertisement auction protocol established by the third-party control end, a plurality of advertisers participating in the advertisement competition are organized to carry out sealed auction, and further calculating the advertisement bids of all the advertisers at the third-party control end to obtain a second high price in the bids of all the advertisers, and taking the advertiser corresponding to the second high price as the winner of the advertisement auction.

The advertisement information processing method is a centralized control advertisement auction mode realized by a third-party control end. The centralized mode ensures that once a third-party control terminal is attacked, information of each advertiser has the risk of information leakage, and the whole business system is paralyzed. Therefore, how to obtain a decentralized advertisement information processing method is still a problem to be solved.

Detailed Description

The technical solutions in the embodiments of the present invention will be described below with reference to the drawings in the embodiments of the present invention.

The basis for the existence of an ad exchange is based on the trust of the advertiser and advertiser. However, this trust is likely to be challenging due to some human, non-resistant, etc. factors: such as hacking, advertising platform repugnance, and high cost. All advertisement auction platforms in the industry are centralized platforms, that is, the platform is a centralized organization. All advertisements, from advertiser access, to advertiser bid, to advertisement pricing and final placement, all rely on the advertising trading platform. This causes the following problems: the information is opaque. The centralized mode ensures that once the third-party control end is attacked, the information of each advertiser has the risk of information leakage and the whole business system is paralyzed. Therefore, how to obtain a decentralized advertisement information processing manner is still a problem to be solved.

In order to solve the problems in the prior art, the embodiment of the invention realizes the advertisement auction by establishing a block chain platform integrated with safe multi-party computation. Decentralization is realized through a block chain, auction logic is realized through an intelligent contract on the block chain, the privacy of bidding in the auction process is protected through safe multi-party calculation, and fairness is kept. Since the blocks of the block chain are generated periodically, the method is well suitable for the service characteristic of the regular auction of the advertisement.

To achieve the above object, a first aspect of the embodiments of the present invention discloses an advertisement information processing system, as shown in fig. 1. Fig. 1 is a block diagram of an advertisement information processing system according to an embodiment of the present invention, including: a plurality of advertiser nodes including a first advertiser node and a second advertiser node, wherein:

a first advertiser node 101, configured to send an advertisement auction request after determining that an advertisement auction initiation condition is satisfied, and send participation information indicating whether or not to participate in the advertisement auction; and sending preparation data for auction and election when the user participates in the advertisement auction.

In order to solve the technical problem that once a third-party control terminal is attacked, information of each advertiser has a risk of information leakage and a whole service system is paralyzed due to the fact that a centralized advertisement information processing mode causes the third-party control terminal to be attacked, the control of the third-party control terminal is removed by combining a block chain technology on an existing advertisement information processing platform, a plurality of advertiser nodes can independently control an interaction mode of advertisement information, and a decentralized advertisement information processing mode is further obtained.

The block chain technology, BT (block chain technology) for short, also called as distributed book technology, is an internet database technology, and is characterized by decentralization and public transparency, so that everyone can participate in database recording. It is described in popular terms: if we assume the database as a book, the reading and writing of the database can be regarded as an accounting behavior, the principle of the block chain technology is to find the person with the fastest accounting speed in a period of time, the person accounts, and then the page of information of the book is sent to other owners in the whole system. This is equivalent to changing all records in the database and sending to every other node in the whole network, so the blockchain technology is also called distributed ledger.

Based on blockchain technology, people can establish various decentralized applications, such as exchanges, anonymous socialization, cross-border transfers, and the like. Decentralization applications have a number of excellent features: robustness, if a certain node stops service, the whole system cannot be influenced; safety, the single node can not influence the system; P2P (Peer-to-Peer network), users of all applications transact directly without an intermediary.

In the embodiment of the present invention, the block chain technology is deployed at each advertiser node of the existing advertisement information processing platform, a block chain network is established by the block chain technology, and a system formed by a plurality of advertiser nodes deployed with the block chain technology is defined as the advertisement information processing system of the embodiment of the present invention. The advertisement information processing system is not controlled by a third-party control platform, and the interaction mode of controlling the advertisement information can be autonomously controlled by a plurality of advertiser nodes in the advertisement information processing system through a block chain technology.

In the embodiment of the present invention, each advertiser node has the same deployment mode and function, and is an equal advertiser node, and for convenience of description, the advertiser node initiating the advertisement auction request is defined as the first advertiser node 101, and the remaining advertiser nodes are defined as the second advertiser nodes 102. In addition, it may be desirable for the implementer to define the advertiser node that initiated the advertisement auction request as the second advertiser node 102 and the remaining advertiser nodes as the first advertiser node 101.

In the advertisement information processing system according to the embodiment of the present invention, the first advertiser node 101 is specifically configured to send an advertisement auction request and send participation information indicating whether or not to participate in the advertisement auction when it is determined that an advertisement auction initiation condition is satisfied; and sending preparation data for auction and election when the user participates in the advertisement auction.

The advertisement auction initiating condition of the embodiment of the invention is a condition for determining the advertisement auction, and the condition is a condition for autonomously initiating an advertisement auction request by an advertiser node combined with a block chain technology. For example, in the embodiment of the present invention, the advertisement auction initiation condition may be set as: the blocks of the block chain reach the preset block height of the intelligent contract.

Optionally, the first advertiser node 101 is specifically configured to send an advertisement auction request after determining that a block of the block chain of the own advertiser node reaches a preset block height of the intelligent contract.

The preparation data in the embodiment of the present invention is data participating in the calculation of the advertisement auction, for example, privacy data stored in the local server by the advertiser node participating in the advertisement auction of this time, and blockchain data stored in the blockchain participating in the calculation of the advertisement auction of this time.

The second advertiser node 102 is configured to, after receiving the advertisement auction request sent by the first advertiser node 101, send participation information indicating whether to participate in the advertisement auction of this time for the advertisement auction request, and send preparation data for auction bidding of itself when participating in the advertisement auction of this time; receiving respective participation information sent by other advertiser nodes and respective preparation data for auction sent by other advertiser nodes participating in the advertising auction; and determining the advertiser nodes winning in the auction bidding of the advertisement based on the preparation data of the advertiser nodes participating in the auction bidding of the advertisement.

The first advertiser node 101 is further configured to receive respective participation information sent by other advertiser nodes when the first advertiser node participates in the advertisement auction, and receive respective preparation data for the auction sent by other advertiser nodes participating in the advertisement auction; and determining the winning advertiser node for the auction election of the advertisement based on the preparation data of the advertiser nodes participating in the advertisement auction.

After the advertisement auction request initiated by the first advertiser node 101 is sent to the second advertiser node 102 of the advertisement information processing system through the blockchain network, the second advertiser node 102 sends participation information indicating whether or not to participate in the advertisement auction to other advertiser nodes of the advertisement information processing system in response to the advertisement auction request. The participation information indicates whether the second advertiser node 102 participates in the advertisement auction, and includes participation information participating in the advertisement auction and non-participation information not participating in the advertisement auction.

When the second advertiser node 102 itself participates in the advertisement auction, the private data participating in the advertisement auction is taken out from the local server, encrypted into encrypted data, and sent to other advertiser nodes participating in the advertisement auction through the secure multiparty calculation rule.

In addition, the second advertiser node 102 also receives participation information sent by other advertiser nodes, and receives preparation data of other advertiser nodes participating in the advertisement auction, where the preparation data includes encrypted data obtained by the other advertiser nodes from the local server after the privacy data is encrypted, and blockchain data.

Optionally, the second advertiser node 102 is specifically configured to receive, according to participation information recorded on a blockchain of the own advertiser node and participating in the advertisement auction, encrypted data for the auction sent by other advertiser nodes participating in the advertisement auction, and blockchain data of the advertiser nodes participating in the advertisement auction calculation under the secure multiparty calculation rule.

Optionally, the first advertiser node 101 is specifically configured to calculate, according to a secure multiparty calculation rule, encrypted data and block chain data of advertiser nodes participating in the advertisement auction of this time, and determine, as target data, encrypted data in accordance with a preset winning rule of the advertisement auction of this time in a calculation result; determining the advertiser node corresponding to the target data as a winning advertiser node for the auction and election of the advertisement;

the second advertiser node 102 is specifically configured to calculate, according to the secure multiparty calculation rule, encrypted data and block chain data of advertiser nodes participating in the advertisement auction of this time, and determine, as target data, encrypted data that conforms to a preset winning rule of the advertisement auction of this time in the calculation result; and determining the advertiser node corresponding to the target data as the winning advertiser node for the auction and election of the advertisement.

After the preparation data is received, the encrypted data and the block chain data of the advertiser nodes participating in the advertisement auction are calculated at the second advertiser node 102 according to a safe multiparty calculation rule, and the encrypted data which accords with a preset winning rule of the advertisement auction in the calculation result is determined as target data; and determining the advertiser node corresponding to the target data as the winning advertiser node for the auction and election of the advertisement.

The safe multiparty computation means that each of a plurality of participants has own private data, and under the condition that each participant does not reveal own private data, a function taking the private data of each participant as input is computed. Such as the classical "millionaire problem": two rich people want to know who has the most deposits, but they do not want others to know their deposits. One method is to assume that there is a notarization institution as an intermediary, and these people respectively tell the notarization institution their own deposit amount, which tells all people what the most deposit amount is. Secure multi-party computing is a computing method in the prior art and is not described in detail here.

And finally, determining the advertiser node which finally accords with the preset winning rule at one advertiser node, and informing the winning advertiser node to each advertiser node of the advertisement information processing system in a broadcasting way.

The advertisement information processing system provided by the embodiment of the invention realizes a decentralized advertisement information processing mode, so that the safety of the whole service system is improved. Specifically, a block chain technology is deployed at a plurality of advertiser nodes, after the condition that an advertisement auction initiating condition is met is determined, a first advertiser node sends an advertisement auction request and sends participation information indicating whether the first advertiser node participates in the advertisement auction; when the user participates in the advertisement auction, the user sends preparation data for auction and election; after receiving the advertisement auction request, the second advertiser node sends participation information indicating whether the second advertiser node participates in the advertisement auction, and sends preparation data for auction and election when the second advertiser node participates in the advertisement auction; receiving respective participation information sent by other advertiser nodes and respective preparation data for auction sent by other advertiser nodes participating in the advertisement auction; and determining the winning advertiser node for the auction bidding of the advertisement based on the preparation data of the advertiser nodes participating in the auction bidding of the advertisement. The embodiment of the invention enables a plurality of advertiser nodes to independently control the interaction mode of the advertisement information through the block chain technology, thereby obtaining a decentralized advertisement information processing mode. In addition, the embodiment of the invention solves the problem that once the third-party platform is attacked, information of each advertiser is leaked when the third-party platform processes data at the third-party control end in the prior art by calculating at each advertiser node, so that the safety of the whole service system is improved. And the data privacy of each advertiser is protected through safe multiparty calculation, and the competition safety and the fairness of each advertiser are further ensured.

In the embodiment of the present invention, each advertiser node has the same deployment mode and function, and is an equal advertiser node, and for convenience of description, the advertiser node initiating the advertisement auction request is defined as the first advertiser node 101, and the remaining advertiser nodes are defined as the second advertiser nodes 102. The following specifically describes an advertisement information processing method applied to the first advertiser node 101 in an advertisement information processing system including a plurality of advertiser nodes.

To achieve the above object, a second aspect of the embodiments of the present invention discloses an advertisement information processing method, which is applied to a first advertiser node in an advertisement information processing system including a plurality of advertiser nodes, as shown in fig. 2. Fig. 2 is a flowchart of an advertisement information processing method according to an embodiment of the present invention, where the method includes:

s201, after determining that the conditions for initiating the advertisement auction are met, sending an advertisement auction request.

The advertisement auction initiating condition of the embodiment of the invention is a condition for determining the advertisement auction, and the condition is a condition for autonomously initiating an advertisement auction request by an advertiser node combined with a block chain technology.

Referring to the description of the block chain technique in the above embodiments, the description is omitted here.

In the embodiment of the present invention, a blockchain technology is deployed at each advertiser node of an existing advertisement information processing platform, a blockchain network is established by using the blockchain technology, and a system formed by a plurality of advertiser nodes deployed with the blockchain technology is defined as the advertisement information processing system in the embodiment of the present invention. The advertisement information processing system is not controlled by a third-party control platform, and the interaction mode of controlling the advertisement information can be autonomously controlled by a plurality of advertiser nodes in the advertisement information processing system through a block chain technology.

An intelligent contract is a set of commitments defined in digital form, including agreements on which contract participants can execute the commitments. The intelligent contract is stored on the block chain of each advertiser node, and the block height set by the intelligent contract is used as a condition for triggering the advertisement auction request. I.e., a threshold is set for the block height, and when the block height of the block chain reaches the threshold, the first advertiser node initiates an advertisement auction request.

S202, the participation information indicating whether the user participates in the advertisement auction is sent.

After the first advertiser node initiates an advertisement auction request, the first advertiser node sends participation information indicating whether the first advertiser node participates in the advertisement auction to other advertiser nodes of the advertisement information processing system. The participation information indicates whether the first advertiser participates in the advertisement auction, wherein the participation information includes participation information participating in the advertisement auction and non-participation information not participating in the advertisement auction.

And S203, when the user participates in the advertisement auction, sending preparation data for auction and election of the user.

When the sent participation information is participation information participating in the advertising auction, the first advertiser node sends preparation data used for auction election of the first advertiser node, and the preparation data comprises encrypted data obtained by the first advertiser node from a local server after the privacy data are encrypted and blockchain data participating in the advertising auction calculation.

S204, receiving respective participation information sent by other advertiser nodes and respective preparation data for auction sent by other advertiser nodes participating in the advertisement auction.

The first advertiser node will also receive respective participation information sent by other advertiser nodes and respective preparation data for the auction sent by other advertiser nodes participating in the advertising auction. The preparation data comprises encrypted data obtained by encrypting the privacy data acquired by other advertiser nodes from respective local servers and blockchain data participating in the calculation of the advertising auction.

S205, based on the preparation data of the advertiser nodes participating in the advertisement auction, determining the winning advertiser nodes for the advertisement auction.

After the preparation data is obtained, the encrypted data and the block chain data of the advertiser nodes are calculated at the first advertiser node through a safe multiparty calculation rule, then the encrypted data meeting the preset winning rule of the advertisement auction is screened out, and the advertiser nodes corresponding to the encrypted data are determined as the advertiser nodes winning the advertisement auction. The preset winning rule can be set by real-time personnel, for example, the second highest price in the encrypted data of all advertiser nodes is taken as a winner of the advertisement auction.

In the advertisement information processing method provided by the embodiment of the invention, the advertising auction request can be automatically controlled and initiated by the advertiser node through the block chain technology, the participation information indicating whether the advertiser node participates in the advertising auction is sent according to the advertising auction request, and the preparation data for auction and election is sent when the advertiser node participates in the advertising auction; receiving respective participation information sent by other advertiser nodes and respective preparation data for auction sent by other advertiser nodes participating in the advertisement auction; and determining the winning advertiser node for the auction bidding of the advertisement based on the preparation data of the advertiser nodes participating in the auction bidding of the advertisement. A decentralized advertising information processing mode is obtained. In addition, the embodiment of the invention solves the problem that once the third-party platform is attacked, information of each advertiser is leaked when the third-party platform processes data at the third-party control end in the prior art by calculating at each advertiser node, so that the safety of the whole service system is improved. And the data privacy of each advertiser is protected through safe multiparty calculation, and the competition safety and the fairness of each advertiser are further ensured.

Optionally, in an embodiment of the advertisement information processing method according to the embodiment of the present invention, after determining that the advertisement auction initiation condition is satisfied, sending an advertisement auction request includes:

and after determining that the block of the block chain of the advertiser node reaches the preset block height of the intelligent contract, sending an advertisement auction request.

In bitcoin networks, data is permanently recorded in the form of files, which we call blocks. A block is a record set of some or all of the latest bitcoin transactions and is not recorded by other previous blocks. A block can be thought of as a city logger who logs a separate page of paper (change log to real estate property) or a general ledger of a stock exchange. In most cases, new blocks will be added to the end of the record (named block chain in bitcoin), which once written cannot be changed or deleted anymore. Each tile records all events that occurred before it was created.

In the embodiment of the invention, the block height of the block chain is used as a condition for triggering the advertisement auction request, namely, a threshold value is set for the block height, and when the block height of the block chain reaches the threshold value, the first advertiser node initiates the advertisement auction request.

Therefore, the advertisement auction system can realize that the advertiser node autonomously initiates the advertisement auction request.

Optionally, in an embodiment of the advertisement information processing method according to the embodiment of the present invention, the receiving preparation data for an auction, sent by other advertiser nodes participating in an advertisement auction, in S204 includes:

step one, receiving encrypted data which are respectively used for auction and sent by other advertiser nodes participating in the advertisement auction according to participation information which is recorded on a block chain of the advertiser node and participates in the advertisement auction.

The embodiment of the invention relates to an implementation process for receiving preparation data of other advertiser nodes participating in the advertisement auction when a first advertiser node participates in the advertisement auction.

Each advertiser node needs to maintain its own block link point, and the data held by one block link point can be divided into two parts: a) Block chain data. These data are stored on the blockchain, and thus each node synchronizes the data. Such as ad slot information, etc.; b) Privacy data. The data is stored in a local server of the advertiser node, the advertiser node does not want the data to be known by other advertiser nodes, and when interaction is needed, the data can be sent to the other party in an encrypted form according to the safe multi-party calculation rule. Such as bids by advertisers, targeting information, etc. The embodiment of the invention receives the encrypted data which are respectively used for auction and sent by other advertiser nodes participating in the advertisement auction according to the participation information which is recorded on the block chain and participates in the advertisement auction.

Specifically, in the information interaction process, the blockchain of each advertiser node records current information interaction information, including information sending parties, receiving parties and interaction information. And searching participation information participating in the advertisement auction on the record of the block chain of the first advertiser node, and further receiving encrypted data which are sent by other advertiser nodes participating in the advertisement auction and are respectively used for encrypting the privacy data of the auction.

And step two, receiving block chain data of the advertiser nodes participating in the advertisement auction calculation under the secure multiparty calculation rule.

After receiving the encrypted data obtained by encrypting the private data used for the auction, the step is to receive the block chain data of the advertisement light node participating in the advertisement auction calculation under the secure multiparty calculation rule.

Therefore, the first advertiser node can receive the preparation data of each advertiser node participating in the advertisement auction, and the autonomous interaction of the data of each advertiser node can be realized through the blockchain technology.

Optionally, in an embodiment of the advertisement information processing method according to the embodiment of the present invention, the determining, based on the preparation data of the advertiser node participating in the advertisement auction, the advertiser node winning in the advertisement auction includes:

step one, calculating the encrypted data and the block chain data of the advertiser nodes participating in the advertisement auction according to a safe multiparty calculation rule, and determining the encrypted data meeting a preset winning rule of the advertisement auction in a calculation result as target data.

The embodiment of the invention is an implementation mode of determining the winning advertiser node for the auction and election of the advertisement at the first advertiser node through a safe multiparty computation rule. The step is an implementation mode that the received preparation data of other advertiser nodes is calculated at the first advertiser node through a safe multiparty calculation rule.

The safe multiparty computation means that each of a plurality of participants has own private data, and under the condition that each participant does not reveal own private data, a function taking the private data of each participant as input is computed. Such as the classical "millionaire problem": two rich people want to know who has the most deposits, but they do not want others to know their deposits. One method is to assume that there is a notarization institution as an intermediary, and these people respectively tell the notarization institution their own deposit number, and the notarization institution tells all the people what the most deposit number is. Secure multi-party computing does not require an intermediary to participate. The participants perform the computation by communicating with each other, with the result that the participants know the result of the computation, but do not know the private information of the other participants. The security of secure multiparty computation means that the participants have no way to deduce any other private data than to know the result of the function computation.

In the embodiment of the invention, the preset winning rule is a rule given by implementers and corresponding to the determined advertisement auction winner; the target data is the determined winning data. For example, the second highest price of all advertiser node bids is determined as the target data.

Each advertiser node participating in the auction needs to maintain its own blockchain, one advertiser node is both a blockchain node and a secure multiparty computing node, and the process of conducting the auction is recorded on the blockchain for verification in case of errors.

According to the principle of the safe multiparty calculation, the encrypted data and the block chain data sent by other advertiser nodes are subjected to partial calculation of the safe calculation at each advertiser node participating in the advertising auction. And determining the encrypted data which accords with the preset winning rule of the advertisement auction in the calculation result as target data.

Data held by a block link point can be divided into two parts: blockchain data, privacy data. Intelligent contracts involving multiple parties' computations may reference different data: private data, data with access rights and blockchain data. The intelligent contract is stored on the block chain, and each advertiser node can scan the contract to confirm whether the local node participates in the advertisement auction or not. The advertiser nodes participating in the auction acquire private data of the auction of the users from the local server for encryption, and the encrypted private data is calculated through secure multiparty calculation. When discovering the data access with the authority, the advertiser nodes participating in the auction request data from other advertiser nodes. When all data is ready, each advertiser node participating in the secure multiparty computation begins to perform the multiparty computation. And determining the encrypted data which accords with the preset winning rule of the advertisement auction in the calculation result as target data.

And step two, determining the advertiser node corresponding to the target data as a winning advertiser node for the auction and election of the advertisement.

After the target data is determined through safe multiparty calculation, the advertiser node corresponding to the target data is determined as the winning advertiser node of the auction and election of the advertisement.

Therefore, the embodiment of the invention can carry out calculation on each advertiser node participating in the advertising auction through safe multi-party calculation, thereby ensuring the data security of each advertiser node and the fairness of the calculation result.

The following specifically describes an advertisement information processing method applied to a second advertiser node in an advertisement information processing system including a plurality of advertiser nodes.
