Based on the foregoing embodiment, referring to fig. 2, a flowchart of a method for controlling a transaction of a target object based on a block chain in the embodiment of the present application is specifically shown, where the method includes:
step 200: and receiving a target object acquisition request sent by any request initiating node.
The target object obtaining request at least comprises a target object identifier.
In the embodiment of the application, when a user wants to trade a target object, a target object identifier corresponding to the target object to be purchased is found, and the target object identifier is input into a request initiating node, so that the request initiating node acquires the target object identifier input by the user, generates a target object acquisition request containing the target object identifier, and then sends the target object acquisition request to a management platform node, and the management platform node receives the target object acquisition request sent by the request initiating node. It should be noted that each target object corresponds to a target object identifier, the target object identifier is a unique identifier representing a type of the target object, and the target object may be, for example, an artwork.
Further, in order to ensure that the request initiating node is a valid node, before receiving a target object acquisition request sent by the request initiating node, the validity of the request initiating node needs to be checked, and the following describes in detail the step of checking the validity of the request initiating node in this embodiment, specifically including:
s1: and acquiring the registration information input by the user and sent by the request initiating node.
Wherein, the registration information at least comprises an identity code.
In the embodiment of the application, the user inputs the registration information about the user into the request initiating node, so that the request initiating node sends the registration information to the management platform node after acquiring the registration information input by the user, and the management platform node acquires the registration information sent by the request initiating node.
The registration information at least includes an identity code, and for example, the registration information may also be one or any combination of the following: user name information, mailbox IP address, mobile phone number, user contact address, and the content of the registration information is not limited in the embodiment of the present application.
S2: and acquiring credit record information and illegal transaction information of the user from the third-party platform according to the identity code.
In the embodiment of the application, after the identity code of the user is acquired, credit record information and illegal transaction information about the user are acquired from a third-party platform according to the identity code.
The credit record information and the illegal transaction information are recorded in the third-party platform in advance, and the third-party platform stores a plurality of users and the credit record information and the illegal transaction information corresponding to the users.
If the user has illegal transaction behaviors, the illegal transaction information contains record information when the illegal transaction behaviors are carried out, if the user does not have bad records, the credit record information is 'good credit', and if the user does not carry out illegal transaction behaviors, the record information in the illegal transaction information is 'illegal transaction information not'.
S2: and determining the trust degree score of the user according to the credit record information, the illegal transaction information and the corresponding weight.
In the embodiment of the application, the trust degree score of the user is calculated according to the credit record information, the weight corresponding to the credit record information and the weight corresponding to the illegal transaction information.
Note that the score is lower as the number of bad records in the credit record information increases, the score is the highest when the credit record information is good, the score is lower as the number of records in the illegal transaction information increases, and the score is the highest when the number of records in the illegal transaction information increases.
S3: and determining that the trust degree score is greater than a preset trust degree score threshold value.
In the embodiment of the application, after the trust score is calculated, whether the trust score is larger than a preset trust score threshold value or not is judged, if the trust score is larger than the preset trust score threshold value, the request initiating node is determined to be a legal node, the target object transaction processing can be continuously carried out, and the registration information is stored, so that the request initiating node is screened from a source, the probability that a user violates a transaction rule during transaction is reduced, the transaction environment is purified, and the transaction success rate is improved.
Further, before receiving a target object acquisition request sent by a request initiating node, firstly, scan data about a target object needs to be acquired, which specifically includes:
s1: and receiving the scanning data of the target object sent by the provider node.
The scanning data is obtained by scanning the target object by the provider node.
In the embodiment of the application, the provider node scans the target object through preset scanning software so as to obtain scanning data about the target object, and then the provider node sends the scanning data to the management platform node, so that the management platform node obtains the scanning data sent by the provider node.
The scanning data comprises pictures and videos, the scanning data can be compressed packets, the sizes of the pictures and the videos can be detected when the scanning data is transmitted, a single picture cannot exceed 20 million, a single video cannot exceed 200 million, rejection is given when the sizes of the pictures and the videos exceed specified values, normal browsing is prevented from being influenced due to the fact that the pictures and the videos are too large, and the pictures and the videos are too large to be beneficial to subsequent downloading work.
It should be noted that, when the target object is an artwork and the artwork is scanned, each side of the artwork needs to be scanned, and the single-side scanning is not less than 8 seconds, so that the integrity of the scanned data of the artwork can be ensured, and the accuracy of artwork identification can be improved.
And when the scanning data received during the transmission of the scanning data of the target object is missing or has error messy codes, the transmission is automatically stopped, or the management platform node does not feed back the information of the received scanning data to the provider node, and actively resends the scanning data after a period of time, so that the transmission integrity of the scanning data is ensured.
It should be noted that, when the provider node issues the target object to be traded to the management platform node, a data transmission path may be established on the basis of the blockchain, and then data transmission is performed, so that during data transmission, in order to further improve the security of data transmission, the transmitted scan data may also be encrypted, and the method specifically includes:
a1: and receiving each encrypted code stream sent by the provider node.
And the encrypted code streams are obtained by decomposing the scanning data of the target object into the code streams by the provider node and encrypting the code streams through a preset encryption algorithm.
In this embodiment of the application, the provider node decomposes the scan data of the target object into code streams, that is, the scan data is composed of the code streams, and encrypts each code stream respectively through a preset encryption algorithm to obtain each encrypted code stream, and then the provider node sends each encrypted code stream to the management platform node, and the management platform node receives each code stream sent by the provider node.
A2: and decrypting the encrypted code stream according to a pre-stored private key to obtain each code stream.
In the embodiment of the application, after receiving each code stream sent by a provider node, a management platform node decrypts each encrypted code stream according to a pre-stored private key to obtain each code stream.
A3: and splicing the code streams to obtain the scanning data of the target object.
In the embodiment of the application, after the code streams are obtained through decryption, the code streams are spliced to obtain the scanning data of the target object, so that the scanning data are subjected to encryption processing in the transmission process, and the safety of the data can be further ensured.
S2: from the scan data, spectral features of the target object are determined.
In the embodiment of the application, the spectral characteristics of the target object are determined according to the scanning data.
The scanning data may be, for example, light reflected by a surface of the target object, which is not limited in the embodiment of the present application.
For example, the spectral characteristics of the target object can be obtained by inputting the acquired reflected light from the surface of the target object to a spectrum analyzer.
S3: and comparing the spectral characteristics with the spectral characteristics stored in a preset object database, and if the comparison is successful, determining that the identification result of the target object is a genuine product.
In the embodiment of the application, according to the pre-obtained identification of the target object, the stored target object can be found from the object database, the spectral feature corresponding to the target object is found, the obtained spectral feature is compared with the found spectral feature, if the obtained spectral feature is determined to be successfully compared with the found spectral feature, the identification result of the target object is determined to be a genuine product, and if the obtained spectral feature is determined to be not successfully compared with the found spectral feature, the identification result of the target object is determined to be a counterfeit product.
In this way, the acquired spectral characteristics are compared with the spectral characteristics stored in the object database for analysis, so that the target object is identified, and the subjectivity and the uncertainty and instability of the identification result caused by the need of damaging the identification method of the target object or artificial identification are avoided.
S4: and generating a target object identifier corresponding to the target object of which the identification result is the genuine product, and establishing an association relation between the target object and the target object identifier.
In the embodiment of the application, when the identification result of the target object is determined to be the genuine product, the target object identifier corresponding to the target object of which the identification result is the genuine product is generated, and the association relationship between the target object and the target object identifier is established.
Further, after the scan data of the target object is stored in the management platform node, the management platform node may further classify the scan data of each target object, put different task classes into different task classes, receive the data sharing instruction sent by the provider node and the identity information of the provider node, and store the identity information of the provider node and the data ID of the sent scan data of the target object.
Furthermore, the request initiating node can also acquire the scanning data of the target object corresponding to the target object identifier from the management platform node, so that the request initiating node can conveniently and primarily screen favorite target objects, and the transaction efficiency is improved.
It should be noted that, when the management platform node performs classified storage on the scan data of the target object, the management platform node classifies the target object, then displays each target object in a corresponding category, photographs six visual angles and the inside of the target object during display, and then displays the target object on line for people to watch.
Step 210: and determining a target object corresponding to the target object identifier, determining a provider node to which the target object belongs, and sending a target object acquisition request to the determined provider node so as to enable a request initiating node and the provider node to perform transaction control processing.
In the embodiment of the application, after the target object identifier in the target object acquisition request is acquired, the target object corresponding to the target object identifier is determined according to the association relationship between the target object identifier and the target object, and which provider node the target object belongs to is searched, so that the provider node to which the target object belongs is determined, and then the target object acquisition request is sent to the determined provider node, so that the provider node and the request initiating node perform target object transaction processing.
For example, the management platform node determines an artist for which the buyer applies for reservation according to the target object acquisition request, and sends the target object acquisition request to the artist.
The target object acquisition request can also comprise bid mode information, payment mode information and delivery mode information. In the following, in this embodiment of the present application, a target object acquisition request is sent to a determined provider node, so that the step of performing target object transaction processing by a request initiating node and the provider node is described in detail, specifically including:
s1: and if the response information returned by the provider node is determined to be received, generating the transaction contract information.
And the response information is generated by the provider node based on the bid mode information, the payment mode information and the delivery mode information in the target object acquisition request.
In the embodiment of the application, after receiving a target object acquisition request sent by a management platform node, a provider node determines whether bid mode information, payment mode information and delivery mode information of a seller of the provider node and a buyer of a request initiating node can be agreed, if yes, the provider node generates response information and returns the generated response information to the management platform node, and if the management platform node determines to receive the response information returned by the provider node, the management platform node generates intelligent contract information.
It should be noted that the intelligent contract information at least includes offer mode information, payment mode information, and delivery mode information that the provider node and the request initiating node agree with each other.
Further, if the provider node and the request initiating node cannot agree based on the bid mode information, the payment mode information and the delivery mode information, negotiation can be performed through the management platform node.
For example, after the buyer and the seller make a successful appointment, the buyer and the seller can communicate with each other on line, video or voice can be performed, the buyer and the seller can directly talk through the on-line communication, the buyer and the seller can know the artwork more deeply and the other side, the authenticity of the artwork transaction is improved, and the on-line communication is safer and more reliable.
