Description

A method of art circulation and identification registration based on block chain and expert system

technical field

The invention relates to the field of art circulation, in particular to a method for art circulation and identification and registration based on a block chain and an expert system.

Background technique

At present, in the mainstream formal way of art transaction, auction houses, which are usually centralized institutions, bring high costs to art transactions. Mainly reflected in: Auction houses often overestimate the value of artworks, resulting in low turnover rates and high deposits, high storage fees and high commissions. There is even a phenomenon that the auction house colludes with the appraisal agency to fabricate the buyer and the appraisal report to cheat the client of high appraisal fees. In the process of informal transactions, the lack of transaction contracts leads to the risk of rights protection in transactions.

Blockchain is an emerging technology that has emerged with digital currencies such as Bitcoin. It has the characteristics of decentralization and non-tampering. It records information within a period of time into blocks, and adjacent blocks pass hashes before Linked together to form a distributed ledger that cannot be tampered with. Recording transactions and identification information through blockchain technology has the characteristics of non-tampering, which can make transaction records provide proof of the existence of transaction facts, prevent sellers from denying due to incomplete information, and can also promptly detect appraisers who spam false identification reports. And its distributed storage feature can prevent the harm caused by the central database being attacked. Make it more secure than the centralized cultural relics registry.

An expert system is an intelligent computer program system that can use the knowledge and experience of experts in a certain field to solve problems in this field. It applies artificial intelligence technology and computer technology to simulate the decision-making process of human experts from the knowledge and experience provided by experts to solve complex problems. The art identification expert system uses the public information recorded on the blockchain for machine learning, and forms an expert system through combined analysis. When it is necessary to inquire about its judgment on a specific artwork, analyze the description information of the artwork based on its accumulated knowledge and experience, and make a judgment on the possibility of whether it is a fake.

At present, there is no technology that uses the blockchain to record transactions and appraisals at the same time, nor does it use the information recorded in the blockchain to perform machine learning and affect the generation of subsequent blockchain information. At the same time, there is no artwork appraisal based on this expert system.

Contents of the invention

The purpose of the present invention is to address the deficiencies of the above-mentioned prior art and provide a method for art circulation and appraisal registration based on block chain and expert system. Technology, removing central institutions such as auctioneers in the transaction, and establishing an expert system for cultural relics registration and art identification.

The purpose of the present invention can be achieved through the following technical solutions:

A method for artwork circulation and appraisal registration based on block chain and expert system, said method comprising the following steps:

Step 1. Preparatory stage: All buyers and sellers participating in the smart contract in the trading market are open to apply for personal blockchain wallets, and assign addresses and private keys; Establish blockchain wallets for authentication institutions or individuals that have passed the review, assign addresses and private keys, and complete the process of entering the alliance chain;

Step 2. Appraisal stage: use the appraisal market smart contract to record the appraisal process and artwork appraisal results between the submitter and the appraiser;

Step 3. Selection stage: There are three situations for the holder to choose from the artwork in the collection state to meet the various needs of the holder. They are continuing to collect, preparing for sale and re-appraisal. The holder can choose according to needs different operations;

Step 4, transaction stage: record the process of direct art transactions between buyers and sellers with smart contracts in the trading market, based on the characteristics of blockchain decentralization and automatic execution of smart contracts, avoiding the participation of central institutions;

Step 5, expert system stage: through machine learning of the information recorded in the blockchain accumulated in the smart contract, an expert system for art appraisal is established, and opinions are provided for subsequent appraisal;

Step 6. Cultural relics query stage: establish an information query interface based on blockchain data, build a general query mechanism for cultural relics registration, and query cultural relics that have completed identification and input information.

Furthermore, in step 1, the buyer can choose to use different addresses to purchase different products, so that others cannot guess the personal identity behind the address from a single purchase record, which can protect the privacy of the real identity of the trader from being leaked; but the buyer becomes a holder of The queen can choose to actively disclose the association between his identity and address, so as to change the commodity from the collection state to the public transaction state, and at the same time become a seller.

Furthermore, through a group of organizations that do not trust each other and need to be reviewed, the artwork is authenticated before it is allowed to enter the market. The participants in this group of market transactions are mutually distrusted and join freely. In terms of process, artworks must first pass the identification market smart contract in step 2 before they are allowed to circulate and record in the trading market smart contract in step 4.

Furthermore, the identification and classification methods for the characteristics of the scope of application of artworks in the identification stage of step two include the following three categories:

Well-known works of art: including works of art that can be determined using blockchain traceability and have a certain number of existences, including famous cultural relics;

Ordinary cultural relics: including a large number of authentic products with large differences in multiple origins. If there are cultural relics recorded in supporting documents, the uniqueness is determined through description indicators. If not, the identification opinions provided by the expert system are used to identify counterfeit products;

Handicrafts: Genuine products produced in batches in one place of origin with slight differences in workmanship are not included.

Furthermore, the identification market smart contract in step 2 records the unique description information that can determine the uniqueness of the commodity, which is used to prove that the commodity held is the registered commodity, and solve the problem that similar genuine products cannot be distinguished from each other, thereby indirectly proving that other Counterfeiting, while preventing multiple sales of items that have already been sold.

Further, the unique description information can only be authorized to be viewed by the buyer and the return supervisor in the transaction state, so as to prevent others from conducting targeted fraud after viewing the information.

Furthermore, in the trading market smart contract in Step 4, the commodity holder is required to sell the commodity at the address when purchasing the commodity, so as to prove the ownership of the commodity and meet the needs of tracking the commodity circulation chain.

Further, in Step 5, through machine learning research on the publicly recorded transaction facts and identification content on the blockchain accumulated in the smart contract, an expert system for art identification is extracted. The specific steps are as follows:

S1. The expert system uses tools to read block information to collect necessary data from the public identification information of the blockchain;

S2. Learn from off-chain equipment, and form a certain expert identification ability by combining the learned knowledge;

S3. The expert system, as an appraiser, gives appraisal results for specific works of art, and adds the specific judgment results of authenticity to the description field of the art in the form of a transaction.

Further, the identification opinion on the authenticity of the cultural relic provided by the expert system in step five is added to the description field of the cultural relic in a probability estimation manner.

Furthermore, the registration of cultural relics in step 6 is based on the common record of the smart contract in the appraisal market and the smart contract in the trading market. The process of cultural relics appraisal is the process of registration of cultural relics data, and the process of cultural relics trading is the process of registration of cultural relics circulation.

Compared with the prior art, the present invention has the following advantages and beneficial effects:

In the present invention, by combining the transaction market smart contract and the identification market smart contract, the transaction and identification information recorded in the block chain are non-tamperable, so that the transaction record provides proof for the existence of the transaction fact, and prevents the seller from denying due to incomplete information. Timely discover the appraisers who spam false appraisal reports, and its distributed storage characteristics can prevent the harm caused by the central database being attacked, making it safer than the centralized cultural relics registry, and at the same time remove the Auctioneers and other central institutions have established an expert system for cultural relics registration and artwork appraisal, which can meet the needs for commodity appraisal validity and appraisal verification, effectively strengthen the guarantee of the authenticity of traded commodities, and achieve credible, convenient, and low-cost buff.
