S3: comparing the spectral features with the spectral features stored in a preset object database, and if the comparison is determined to be successful, determining that the identification result of the target object is a genuine product.
According to the method and the device, according to the identification of the target object obtained in advance, the stored target object can be searched from the object database, the spectrum characteristic corresponding to the target object is searched, the obtained spectrum characteristic is compared with the searched spectrum characteristic, if the obtained spectrum characteristic and the searched spectrum characteristic are determined to be successfully compared, the identification result of the target object is determined to be a genuine product, and if the obtained spectrum characteristic and the searched spectrum characteristic are determined to be unsuccessfully compared, the identification result of the target object is determined to be a counterfeit product.
In this way, the acquired spectral features are compared with the spectral features stored in the object database for analysis, so that the target object is identified, and the subjectivity and the uncertainty and the instability of an identification result caused by the need of damaging an identification method or manual identification of the target object are avoided.
S4: and generating a target object identifier corresponding to the target object with the identification result being the genuine product, and establishing an association relationship 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 a genuine product, the target object identifier corresponding to the target object whose identification result is a 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 objects are stored in the management platform node, the management platform node may further classify the scan data of each target object, place different task classifications in different task classifications, 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.
Further, the request initiating node can 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 preliminarily screen favorite target objects, and the transaction efficiency is improved.
When the management platform node classifies and stores the scanning data of the target objects, the management platform node classifies the target objects, displays each target object in a corresponding category, photographs six visual angles and the interior of the target object during display, and displays the target object on a 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 that the request initiating node and the provider node perform transaction control processing.

For example, the management platform node determines an artist for which the buyer applies for a reservation based on the target object acquisition request, and transmits the target object acquisition request to the artist.
The target object obtaining request may further include bid mode information, payment mode information and delivery mode information. In the embodiment of the present application, the following describes in detail the steps of sending a target object obtaining request to a determined provider node, so that a request initiating node and the provider node perform target object transaction processing, where the steps specifically include:
s1: and if the response information returned by the provider node is received, generating transaction contract information.

In the embodiment of the present application, after receiving a target object acquisition request sent by a management platform node, a provider node discusses whether bid mode information, payment mode information and delivery mode information can be agreed with a buyer of a request initiating node, if so, the provider node generates response information and returns the generated response information to the management platform node, and if the management platform node determines that the response information returned by the provider node is received, the management platform node generates intelligent contract information.
The intelligent contract information at least comprises bid mode information, payment mode information and delivery mode information which are agreed by the provider node and the request initiating node.
Further, if the provider node and the request initiating node are not able to agree on the basis of the bid mode information, the payment mode information and the delivery mode information, the negotiation may be performed by the management platform node.
For example, after the reservation is successful, the buyer and the seller can carry out online communication, video can be carried out, voice can be carried out, the buyer and the seller can directly converse through online communication, the artwork is known more deeply, the other party is known, the authenticity of the artwork transaction is improved, and the online communication is safer and more reliable.
The bidding mode information is direct payment or an object, the payment mode information is online payment or offline transaction, and the delivery mode information is offline transaction mode or mailing mode.
When online payment is carried out, the request initiating node delivers money to the management platform node for temporary management, the payment is carried out to the provider node after the transaction is confirmed on 1 working day or 3 working days, the delivery mode can be used for ordering off-line transactions between buyers and sellers, and the transaction mode can be used for sending a part instead of the transaction through the management platform node, so that the transaction mode is more flexible, high in selectivity and more applicable.
