Enterprise chain code generation and management method

Abstract

The invention provides an enterprise chain code generation and management method. The enterprise chain code is an enterprise identity scanning code established by a blockchain and a two-dimensional code, and the method comprises the following steps: after a code scanning user requests to scan the enterprise chain code, a front end requests a rear end for generation parameters of the enterprise chain code, and the rear end queries corresponding public key information and updates time; then digital signature is carried out, meanwhile, a key value is returned to the enterprise chain code front end to serve as a generation parameter of the enterprise chain code, and the enterprise chain code is generated by the front end; after a code scanning user scans the enterprise chain code, the enterprise chain code front end requests a code scanning result, the enterprise chain code rear end returns a corresponding public key, updating time and a digital signature, the enterprise chain code front end splices a new link again and requests the enterprise chain code rear end, the enterprise chain code rear end verifies whether the digital signature is tampered or not, and if the verification is passed, a code scanning result of the enterprise chain code is returned. The enterprise chain code generated by the method has timeliness, the propagation risk can be reduced, and tampering can be prevented.

Description

technical field [0001] The invention relates to the field of block chains, in particular to a method for generating and managing enterprise chain codes. Background technique [0002] With the large-scale application of smart terminals (such as smart phones, code scanners), as a QR code carrying certain information, there are more and more usage scenarios for identifying information and sharing information by "scanning" the QR code. It also provides greater convenience for users. [0003] However, there are some problems in the process of using the two-dimensional code: 1. The generation of the two-dimensional code is to form a picture by a string of characters through encoding technology. The pictures will be very dense, and it is difficult to quickly identify when scanning the code; 2. The two-dimensional code coding technology is diverse, there is no formal legal regulation and industry standard to unify and standardize, many two-dimensional code generation leaks data to ...

[0003] However, there are some problems in the process of using the two-dimensional code: 1. The generation of the two-dimensional code is to form a picture by a string of characters through encoding technology. The pictures will be very dense, and it is difficult to quickly identify when scanning the code; 2. The two-dimensional code coding technology is diverse, there is no formal legal regulation and industry standard to unify and standardize, many two-dimensional code generation leaks data to a certain extent Information, anyone can analyze and get the data, there is a security risk
