Seal or signature recognition system based on a block chain

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...

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
