Description

Artwork anti-counterfeiting electronic tag system and method based on block chain

Technical Field

The invention relates to a block chain technology and an electronic tag technology, in particular to an artwork anti-counterfeiting electronic tag system and method based on a block chain.

Background

The block chain technology is a distributed data recording technology for recording all transactions or electronic behaviors in a period of time, namely a distributed public account book technology which is a chain data structure formed by combining data blocks in a sequential connection mode according to a time sequence and is guaranteed to be not falsifiable and counterfeitable in a cryptographic mode. On the blockchain, each transaction can be audited by the participants of the system through a mechanism commonly known by most nodes. In recent years, the phenomenon of counterfeit and shoddy commodities frequently appears, so that the credibility problem of source commodities on a supply chain is emphasized, and particularly, the credibility problem of transactions on the supply chain is more prominent due to asymmetric transaction information among transaction subjects on the whole chain. Building a "centralized" management model is a relatively sophisticated solution that is currently applied in the traditional supply chain management trading model. The biggest characteristic of the blockchain is decentralization. At present, the block chain technology is popularized and used in many countries, and the development of the block chain technology is greatly promoted. By the block chain and anti-counterfeiting, product information is difficult to copy, copy and recycle, an enterprise is helped to establish a unique identification system of commodities, and the identity, the dynamic state and the commodity flow of the commodities are monitored and audited in real time. The platform can also provide digital identity authentication for enterprises and individuals, provide safe and non-falsifiable identity authentication, prevent potential safety hazards of user identity information stealing and network attack, protect user information privacy and establish a more honest network environment.

Original art is always the field of strong trust requirement due to the huge value. The problem of right confirmation in the traditional artwork transaction always exists, and the attribution of the property right, copyright, personal right and property right of the artwork to the approval of each circulation record of the artwork is lack of a long-term effective method with public confidence for establishing the attribution.

Blockchains are applied to the artwork industry and are designed from the underlying logical aspects of the trade in the art market. Admittedly, the safety problem after the artwork is digitalized can be easily realized by the characteristic of the block chain of the distributed account book database, but there is an important problem that is how to digitalize the artwork? If the work of art itself is counterfeit, the entered data will have little meaning. How to achieve source fidelity and link trusted resources is a difficult problem to be solved at present.

At present, the anti-counterfeiting technology mainly comprises two-dimensional code anti-counterfeiting, printing anti-counterfeiting technology and the like. The two-dimensional code anti-counterfeiting technology is based on the design information of bit stream coding. The two-dimensional code technical principle is completely open source, anyone can use the two-dimensional code generator to generate the two-dimensional code required by the person and hide related contents, a counterfeiter can directly forge counterfeit goods by simply copying the two-dimensional code, and the anti-counterfeiting function completely disappears. The code anti-counterfeiting is to set a corresponding unique code for each commodity to be sold in a server background central database, record and store the code in the database, and establish a telephone inquiry and identification network nationwide. The code coating is the most basic form of code anti-counterfeiting, but the biggest defect is that the query process is more complicated, so that the commodity query rate is low, and a counterfeiting space is provided for counterfeiters. The printing anti-counterfeiting technology mainly comprises a printing stock anti-counterfeiting technology, an ink anti-counterfeiting technology and a printing technology anti-counterfeiting. The printing anti-counterfeiting technology has a certain anti-counterfeiting effect, and the anti-counterfeiting technology requires a consumer to master certain printing anti-counterfeiting knowledge, and the biggest problem is that the inquiry condition of the consumer cannot be obtained.
