Method and device for anti-counterfeiting of artwork based on block chain

Abstract

The invention relates to a block chain-based artwork anti-counterfeiting method and device. The method comprises: preserving the information of a first artwork; acquiring image information of the second artwork; comparing the image information of the second artwork with the image information of the first artwork, and if the comparison result is consistent, verifying that the second artwork and thefirst artwork are the same artwork; otherwise, the second artwork and the first artwork are not the same artwork, and the verification fails. The invention completes the comparison and verification of the traded artwork and the seller's pre-sold traded artwork by uploading the image information of the traded artwork by the buyer user during the trading. The method can ensure that the artwork actually bought by the buyer is the artwork seen at the beginning in the process of the art transaction, and avoid the problem of being imitated and replaced in the process of the transaction, which is conducive to ensuring the economic interests of the buyer and the user. The method adopts the image attribute of the artwork itself to realize the anti-counterfeit of the artwork, and the anti-counterfeit is higher.

Description

Technical field [0001] The invention relates to the technical field of anti-counterfeiting of calligraphy, calligraphy and paper printed artwork, and in particular relates to a block chain-based anti-counterfeiting method and device for artwork.

Problems solved by technology

The disadvantage of the former is that the cost of copying the barcode or QR code is low, as long as the anti-counterfeiting code is copied, it can be disguised as a genuine product

The latter is more advanced in technology than the former, but it also has limitations: they all use stories other than artworks to realize the anti-counterfeiting of artworks. Because of the risk of easy counterfeiting and counterfeiting, they cannot well prove the authenticity of the artwork itself. authenticity

The anti-counterfeiting method in the prior art still has the possibility of being copied, or the anti-counterfeiting object is separated from the artwork, so it cannot provide anti-counterfeiting guarantee for the artwork well
