Embodiment Construction

[0045] The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

[0046] like figure 1 As shown, a blockchain-based seal registration method includes the following steps:

[0047] Step 1, collecting images of seals to be registered, specifically collecting images of seal texts to be registered.

[0048] Image acquisition can automatically trigger acquisition and manual trigger acquisition. Automatic trigger acquisition is: through the sensor to sense the change of pressure, start the image collector to collect the image of the seal; manual trigger acquisition is: issue a collection command, start the image collector to image Image collection of printed text.

[0049] Step 2, preprocessing the collected stamp image to remove useless information and noise in ...

Abstract

The invention discloses a seal registration method, a verification method and an anti-counterfeiting system based on a block chain. According to the invention, the characteristics of the seal image are written into the block chain, and the seal to be verified is verified through the smart contract, so that the seal anti-counterfeiting based on the block chain is realized, and the problems that theauthenticity of the seal is difficult to identify and an authentication center has an attacked risk in real life can be perfectly solved.

Description

technical field [0001] The invention relates to a block chain-based seal registration method, verification method and anti-counterfeiting system, belonging to the technical field of article traceability and anti-counterfeiting. Background technique [0002] As an important tool for preventing rape and distinguishing fakes, seals have played an irreplaceable and important role in my country's political, economic and cultural life since ancient times. With the advancement of science and technology, new methods of making seals continue to emerge, and the making of seals is more convenient and refined. However, while people enjoy the convenience brought by high technology, criminals are also using these advanced scientific achievements and technical means to forge Highly simulated seals and imprints, illegal activities, have brought new problems and new challenges to the inspection and identification of seals. [0003] Blockchain technology is based on a decentralized peer-to-p...
