Problems solved by technology

Also, there is the issue of seal or signature misuse
Due to the flaws in seal management, seals are often stolen, and the result of misuse of real seals is more serious than the harm caused by fake seals to the parties concerned. It not only damages the reputation of the parties involved, but also It may even bring legal disputes to the parties involved

Embodiment Construction

[0022] Below in conjunction with embodiment the present invention is further described.

[0023] The present invention is a block chain-based seal or signature recognition system, there are seal or signature providers, seal or signature inquirers and seal or signature verifiers on the block chain; block chain data assets include seal or signature conversion and Storage, seal or signature query compare two smart contracts, and seal or signature database; the implementation method is:

[0024] The seal or signature provider uses the APP to sample the original and clear imprint of the seal or signature, and then upload it to the blockchain in the cloud; the blockchain will call the seal or signature to convert and store the smart contract, and extract the seal or signature The eigenvector of the original image of the seal is then encrypted and stored, and the original image of the seal is deleted at the same time, so as to ensure that the seal pattern will not be stolen from the ...

Abstract

The invention discloses a seal or signature recognition system based on a block chain. A seal or signature provider, a seal or signature querier and a seal or signature authenticator are arranged on the block chain. Wherein the block chain data assets comprise two intelligent contracts of stamp or signature conversion and storage, stamp or signature query and comparison, and a stamp or signature database; The main function of the system is to complete collection and storage of stamps and signatures and query and identification of the stamps. The method has the advantages that the problems thatwhen people identify seals or signatures, efficiency is low, errors are likely to happen, and the seals and the signatures are effectively prevented from being falsely used in reality are solved; Through the seal or signature recognition system based on the block chain, the authenticity of the seal or signature can be efficiently and accurately recognized, and a safe and reliable operation environment is provided for electronic commerce.

Description

technical field [0001] The present invention relates to the application of block chain technology, in particular, relates to a seal or signature identification system based on block chain. Background technique [0002] In a narrow sense, a blockchain is a chained data structure that combines data blocks in a sequential manner in chronological order, and is cryptographically guaranteed to be tamper-proof and unforgeable distributed ledgers. [0003] Broadly speaking, blockchain technology uses block chain data structures to verify and store data, uses distributed node consensus algorithms to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses automated scripts to A new distributed infrastructure and computing method for programming and manipulating data through smart contracts composed of code. [0004] The blockchain mainly solves the trust and security issues of transactions. Generally speaking, the blockchain system...
