One-dimensional code encoding and decoding method

Abstract

The invention provides a one-dimensional code encoding and decoding method which comprises the following steps: S1, converting a character string containing information of codes to be encoded into an initial byte array; S2, encrypting the initial byte array to generate an encrypted byte array; S3, converting the encrypted byte array into a character string containing one-dimensional code information. Through the one-dimensional code encoding and decoding method provided by the invention, the safety of the one-dimensional codes can be improved.

Description

technical field [0001] The invention relates to the field of encryption and decryption, in particular to a one-dimensional barcode encoding and decoding method. Background technique [0002] A one-dimensional barcode is a mark composed of a group of regularly arranged bars, spaces and corresponding characters. "Bar" refers to the part with low reflectivity to light, and "space" refers to the part with high reflectivity to light. These bars and The data composed of blanks express certain information, and can be read by specific equipment and converted into binary and decimal information compatible with computers. Usually, for each item, its code is unique. For ordinary one-dimensional barcodes, the corresponding relationship between barcodes and product information must be established through the database. Applications manipulate and process data. [0003] Existing one-dimensional barcodes are usually not encrypted during the encoding process. Most scanning programs can eas...

AI Technical Summary

Problems solved by technology

[0003] The existing one-dimensional barcodes are usually not encrypted during the encoding process. Most scanning programs can easily identify almost all one-dimensional barcodes. The information in the one-dimensional barcodes can be easily obtained by anyone, and the security is low.
