Quick code scanning signature method based on block chain technology

Abstract

The invention discloses a quick code scanning signature method based on a block chain technology. The quick code scanning signature method comprises the following steps: importing an appointed block chain Ethereum account private key into an intelligent mobile terminal for storage; obtaining a two-dimensional code image converted from to-be-signed data by utilizing a camera of the intelligent mobile terminal, and carrying out image analysis on the obtained two-dimensional code image to obtain two-dimensional code image analysis data; performing Hash operation on the two-dimensional code imageanalysis data to generate a Hash value of to-be-signed data; and based on the block chain Ethereum account private key, performing digital signature on the hash value of the to-be-signed data throughan Ethereum digital signature algorithm, and generating a digital signature result. The method is high in safety, and the efficiency of obtaining the digital signature result can be greatly improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a fast code-scanning signature method based on block chain technology. Background technique [0002] The existing blockchain Ethereum signature system needs to configure the Ethereum environment and complete the import of the private key account before scanning the code. But there are some problems in this way: [0003] 1. The steps of configuring the Ethereum environment are complex and time consuming; [0004] 2. The private key account information is usually complicated, which is not conducive to the entry of the signature system; [0005] 3. The private key account information needs to be entered in plain text on the PC terminal or browser application, the transmission security is low, and there are security risks when using it on multiple terminals. [0006] For this reason, the applicant has found a solution to the above-mentioned problems through beneficial ex...
