The above technical solution of the embodiment of the present invention is described in detail with reference to the application examples below:
referring to fig. 5 in detail, fig. 5 is an overall architecture diagram of an advertisement delivery system based on a block chain technology according to an embodiment of the present invention;
and the advertisement delivery server sets the budget limit of the advertisement delivery according to the advertiser to deliver the advertisement. When there is the advertisement directional delivery user request, advertisement delivery service end promotes the advertisement to advertisement receiving client, and advertisement receiving client shows the advertisement for current user, and the show information of advertisement includes the content of this advertisement, advertisement ID (identification), advertiser ID, if confirm current user when having carried out click operation based on advertisement content, then the show information of advertisement will increase: MD5 value of exposure user ID, (Message Digest Algorithm) MD5 value of exposure user device ID. MD5 is a hash function widely used in the field of computer security to ensure consistency in the information transmission process. Has the following characteristics: 1) compressibility, the length of the calculated MD5 value is fixed for data of any length; 2) the MD5 value is easy to calculate from the original data; 3) the modification resistance is realized, any starting is carried out on the original data, even if only 1 byte is modified, the obtained MD5 values are greatly different; 4) strong collision resistance, knowing the original data and its MD5 value, it is very difficult to find a data with the same MD5 value. MD5 functions to allow large volumes of information to be "compressed" into a secure format during signing of private keys with digital signature software.
If the current user is confirmed to click on the advertisement content, the advertisement receiving client also generates a transaction message: and transferring the money value from the deduction value of the advertiser account to the money value of the account of the advertisement putting service terminal. The deduction value is used for deducting the fee according to the price of the single advertisement sent by the advertisement putting service end, and the transaction information of the advertisement is transmitted back to the advertisement putting service end.
The advertisement receiving client uploads a transaction record consisting of the display information and the transaction information of the advertisement to a network side; the miner node is responsible for collecting transaction records from the network side, recording the transaction records into the blocks, verifying the legality of the transaction records recorded into the blocks according to the block chain, and if the transaction records are legal, adding the blocks recording the transaction records into the block chain, wherein at least one block forms the block chain. The mineworker node is a network node authorized to perform data management in the blockchain. The 'mining' is a nickname of an exploration mode for acquiring the bitcoin, and because the working principle of the 'mining' is very similar to that of mining minerals, a bitcoin explorer who performs mining is also called a 'miner'. In the preferred embodiment of the present invention, the "mineworker node" is defined by the "mineworker" in the bitcoin system.
Referring to fig. 6 in particular, fig. 6 is a schematic structural diagram of blocks according to an embodiment of the present invention, where the structure of each block includes: the block head and the block data, the block head contains a time stamp, the mining difficulty, a nonce (random number) value and a hash (hash) value of a previous block, and the block head structure is basically consistent with the standard block chain head structure. The block data records the transaction record of the advertisement, and comprises: 1) the display information of the advertisement includes: advertiser ID, Ad ID, MD5 exposing user ID, and MD5 exposing user device ID, which are provided primarily to enable the advertiser to query for details of ad placement by tile. 2) The transaction information of the advertisement includes: transferring the money value from the deduction value of the advertiser account to the money value of the account of the advertisement putting service end; this information is provided primarily for both parties billing usage.
After the transaction record of the advertisement is sent to the network side, each miner node can obtain the transaction record of the advertisement and count the transaction record into the block, however, whether the block can be added into the block chain or not needs to carry out validity verification on the transaction record through the miner node. Each miner node calculates the hash value of the current transaction record according to a preset rule, and if the calculated hash value meets a preset requirement, the hash value of the transaction record is issued to a network side; if other miners receive the hash value of the issued transaction record, stopping calculating the hash value of the transaction record, and verifying whether the hash value of the transaction record issued by other miners is correct according to the preset rule; and if more than half of the miner nodes confirm that the hash values of the transaction records issued by other miner nodes are correct, the validity of the transaction records is verified to be passed, so that the blocks recording the transaction records are qualified to be added into the block chain. The preset rule for calculating the hash value of the current transaction record is as follows: each miner node calculates the hash value of the transaction record by using a hash function according to the block data (transaction record) of the block, the timestamp, the mining difficulty, the Nonce value and the hash value of the previous block; the preset verification rule of the hash value of the transaction record issued by the other miner nodes is as follows: calculating the hash value of the transaction record again by using a hash function according to the block data (transaction record) of the block, the timestamp, the mining difficulty, the Nonce value corresponding to the hash value of the transaction record issued by other miner nodes and the hash value of the previous block; and if the recalculated hash value is the same as the hash values issued by other mineworker nodes, confirming that the hash values of the transaction records issued by other mineworker nodes are correct.
A "hash function" is a mapping of an arbitrary length binary value to a shorter fixed length binary value. The mining difficulty is that in order to maintain the block generation speed within a preset fixed time, the difficulty of generating the block is adjusted periodically, and if the block generation speed is high, the mining difficulty is improved. In a preferred embodiment, the hash value is a fixed length value calculated using a mathematical function on the transaction record, and an output hash value is obtained only by inputting a transaction record. Is there a plurality of miners' nodes in the ad delivery system based on the blockchain technique, whose blocks can be recognized by everyone and added to the blockchain? Therefore, the calculation difficulty of the hash value is improved, and the calculation difficulty of the hash value is also called 'ore excavation difficulty'. Faster than the speed at which one obtains a hash value that satisfies the preset condition. The current practice is that the resulting hash value must be less than a certain value, e.g. the first 10 bytes of a 256-bit hash value must be 0. The specific calculation process is as follows: generating a Nonce value, calculating the hash value of the transaction record according to the block data, the timestamp, the ore excavation difficulty and the hash value of the previous block, if the preset condition of the hash value is not met, continuously generating a new Nonce, continuously and circularly calculating until a hash value meeting the preset condition is found, and issuing the block containing the Nonce value and the hash value to the network side.
When other miners receive the hash value issued by the miners who calculate the hash value meeting the preset requirement, stopping calculating the hash value of the transaction record; calculating the hash value of the transaction record by utilizing a hash function again according to the block data, the timestamp, the mining difficulty of the block, the Nonce value corresponding to the hash value of the transaction record issued by other miners and the hash value of the previous block; if the hash value recalculated by more than half of miners is the same as the issued hash value, the issued hash value passes the verification, the current transaction is determined to be legal, and the miners who issue the hash value receive the reward; in a preferred embodiment, the miners who first calculate the hash value meeting the predetermined requirement receive the 'microblog coin', which can be used on the specific social software.
It should be noted that, a block chain is composed of at least one block, and the block chain technology has the following characteristics: 1) decentralization, using distributed accounting and storage, without centralized hardware or management, the rights and obligations of any node are equal, and blocks in the system are commonly maintained by nodes with maintenance functions in the whole system. 2) The block data of the block chain is public to all persons except that private information of transaction parties is encrypted, and anyone can inquire the block data and develop related applications through a public interface, so that the whole system information is highly transparent. 3) Autonomy, blockchains employ a specification and protocol based on agreement (e.g., a set of public transparent algorithms) that enables all nodes in the overall system to freely and securely exchange data in a distrusted environment, such that trust in "humans" changes to trust in machines, and any human intervention does not work. 4) Non-tamper-proof, i.e. information that has been verified and added to the block chaining, is permanently stored, and unless more than 51% of the nodes in the system can be controlled at the same time, the modification of data at a single node is invalid, and thus the data stability and reliability of the block chaining is extremely high. 5) Anonymity, because the exchange among nodes follows a fixed algorithm, data interaction does not need to be trusted (whether the transaction is effective or not can be judged by self by a degree rule in a block chain), and thus a counterparty does not need to make the counterparty trust the counterparty by disclosing the identity, which is very helpful for the accumulation of credit. From the above, the blockchain technique itself has natural attributes to solve the trust problem.
The advertiser can check or download the data in the block chain by means of the advertisement monitoring client, and count the specific details of advertisement delivery according to the data in the block chain so as to achieve the purpose of monitoring the advertisement delivery without depending on any third party mechanism, thereby fundamentally solving the trust problem of advertisers and advertisement delivery media parties.
