Paper artwork tracing and anti-counterfeiting method and system based on block chain

Abstract

The invention discloses a paper artwork tracing and anti-counterfeiting method and system based on a block chain. The method comprises the steps of generating a block chain external account of an artist by means of a personal public and private key pair of the artist, creating an artist intelligent contract including a block chain external account address, a public key in the personal public and private key pair, and the artist personal information; storing the artwork information and the block chain external account address of the artist in the readable area of an NFC chip, storing the private key in the personal public and private key pair in the unredabl area of the NFC chip, and locking the NFC chip to a readable mode; and creating an artwork intelligent contract including the artworkinformation, the block chain external account address, the artwork information, and the ID information of the NFC chip on the block chain; wherein the artwork information includes an artwork name, anartist, a price and an owner. According to the invention, the tracing, true non-tampering and anti-counterfeiting purposes of the paper artwork are achieved.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method and system for traceability and anti-counterfeiting of paper artworks based on block chains. Background technique [0002] At present, the anti-counterfeiting and traceability of the paper art industry mainly rely on methods such as expert identification, X-ray paper analysis, and centralized server feature matching. However, expert identification has problems such as relying heavily on expert level and unstable status; There are problems such as using ancient paper forgery and artificial doping; the method of centralized server feature matching has the problem of relying heavily on the credibility of the center, and internal control is extremely difficult. [0003] Therefore, how to realize traceability, authenticity and anti-counterfeiting with strong credibility of paper artwork is a technical problem that we need to solve. Contents of the invention [0004] T...
