Blockchain technology authentication method based on partial image

Abstract

The invention discloses a blockchain technology authentication method based on a partial image. A partial image of the physical surface of a product at a production end is photographed, a blockchain registration transaction is created by using the partial image and product authentication information as transaction data of the blockchain, and at the time of authentication, a consumer photographs the partial image and an authentication information label at the same position on the physical surface and uses the image recognition technology and blockchain technology to realize the fidelity and traceability of the physical product. The method of the invention uplinks the image of the surface of the physical product as transaction information to the underlying blockchain, ensures that the physical object is not falsified or replaced by identifying whether the physical surface image captured by the authenticator is consistent with the image in the block, and establishes a first link of the Blockchain technology in the fidelity, anti-counterfeiting and traceability of physical products, thereby enabling the blockchain technology to serve the daily lives of the broad masses of the people.

Description

technical field [0001] The invention belongs to the technical field of information processing, and in particular relates to a block chain technology authentication method based on partial images. Background technique [0002] Blockchain technology is a distributed ledger technology that has emerged in recent years. It is a collection of computer information technology applications such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. From the data level, the blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order. It is characterized by decentralization, openness and transparency, unchangeable, and unforgeable. Blockchain technology has broad application prospects in product authenticity and traceability systems. [0003] Although the application of blockchain technology can ensure the anti-counterfeiting and traceability of data in the process of circulation, ther...

Similarly, whether the clear code on the product has been replaced or replaced is unknown to the inquiring person (ie the user). Perhaps the information queried by the clear code does not correspond to the product with the clear code. The clear code is shoddy and provides a loophole, which makes the technical solution of the invention have certain deficiencies in security during actual use.
