Block chain-based steel ex-warehouse list anti-counterfeiting signature and verification method, and block chain-based steel ex-warehouse list anti-counterfeiting verification device

Abstract

The invention relates to a blockchain-based steel ex-warehouse list anti-counterfeiting signature and verification method and device. The anti-counterfeiting signature comprises the following steps: signing configuration; obtaining a signature instruction and an anti-counterfeiting two-dimensional code generation instruction; generating an anti-counterfeiting two-dimensional code, wherein the anti-counterfeiting two-dimensional code uniquely corresponds to the currently signed steel ex-warehouse list; anti-fake two-dimensional code adding and seal signing are carried out on the steel ex-warehouse list according to the signing configuration; the steel ex-warehouse sheet signing process data is subjected to uplink evidence storage; when the steel ex-warehouse list is updated, the steel ex-warehouse list of a new version is subjected to anti-counterfeiting signature again, and signature process data is linked and stored; the anti-counterfeiting verification method comprises the following steps: comparing the scanned anti-counterfeiting two-dimensional code content with information stored on the block chain, and verifying the authenticity of the document. Compared with the prior art, the method has the advantages that the problem that the legal efficacy of the electronic delivery order is not accepted by a customer is solved, the signature process is simplified, the working efficiency is improved, the authenticity of the delivery order can be checked through code scanning, the signed file can be obtained, and the problems of checking and tracing of the delivery order are solved.

Description

technical field [0001] The present invention relates to a kind, in particular to a block chain-based anti-counterfeiting signature, verification method and device for steel outbound documents. Background technique [0002] At present, many steel warehouses issue electronic outbound orders to customers, but there is a problem that the picture stamp does not have legal effect, and some customers do not recognize the electronic outbound order, so warehouse operators need to print the paper outbound order, stamp it manually, and mail it to the customer , The whole process of stamping and sending the paper delivery order takes about 2-3 days, and the work efficiency is low. [0003] In order to ensure the legal validity of the electronic delivery order, the electronic signature and seal of the CA certificate can also be used. The following problems exist in the use of the electronic signature of the outbound order: the electronic signature can check the validity of the CA certif...
