A blockchain-based traceability and anti-counterfeiting method and system for paper artwork

Abstract

The present application discloses a paper artwork traceability and anti-counterfeiting method and system based on a blockchain. The method comprises: generating an external blockchain account of an artist by using a personal public-private key pair of the artist, and creating, on the blockchain, an artist smart contract comprising an external blockchain account address, a public key of the personal public-private key pair, and personal information of the artist; storing, in a readable region of an NFC chip, artwork information and the external blockchain account address of the artist, storing, in an unreadable region of the NFC chip, a private key of the personal public-private key pair, and locking the NFC chip in a readable mode; and creating, on the blockchain, an artwork smart contract of the artwork comprising the artwork information, the external blockchain account address, and ID information of the NFC chip, wherein the artwork information comprises: a work name, the artist, a price, and an owner. The present application achieves highly credible traceability for paper artwork, ensures that the paper artwork is authentic and cannot be falsified, and realizes an anti-counterfeiting function.

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...
