Four-dimensional code and identification method thereof, identification device and server

Abstract

The invention relates to the technical field of electronic identification codes, and provides a four-dimensional code and an identification method thereof, an identification device and a server, aiming at solving the problem that the existing identification codes do not have the editability of the time dimension. The four-dimensional code comprises a plurality of sub-code blocks and an empty codeblock, wherein the plurality of sub-code blocks and the empty code blocks are arranged in a matrix form; Each sub-code block is divided into nxn subspaces filled with code points, and each sub-code block is assigned to a corresponding code according to the position and the number of the filled code points; The null code block is used as an identifier of subsequent information supplementary recording. The four-dimensional code has the editability on the time dimension, and a series of process information such as quality inspection, circulation and even entry and exit of the goods after leavingthe factory can be supplemented to the four-dimensional code, and the consumers can obtain the complete information of the goods; It is conducive to the reasonable purchase of commodities by consumers, to the standardization of the market environment, and to the crackdown on fake and inferior products.

Description

technical field The present invention relates to the technical field of electronic identification codes, in particular to a four-dimensional code and its identification method, identification device and server. Background technique With the development of the Internet age, the production, circulation, and sales of commodities are becoming more and more wide-area and in-depth. It crosses oceans and enters villages, forming a ubiquitous and endless border. And the labels (such as barcodes, QR codes and other identification codes) accompanying commodity packaging have become more and more indispensable information query signs. However, the existing two-dimensional codes or identification codes carry limited information, and it is difficult to enter complete commodity information in standard two-dimensional codes or barcodes. In addition, QR codes or barcodes do not have time-dimension editability, and the process information such as a series of quality inspections, circulation...
