Abstract

The invention discloses a coding method for mixing barcodes and two-dimensional codes, which comprises the following steps: (1) generating barcode images through barcode algorithms through barcode data; Encrypting as a key to obtain two-dimensional code generation information; (3) generating a two-dimensional code image by using the two-dimensional code generation information obtained in step (2) through a two-dimensional code generation algorithm. The invention also discloses a decoding method and an encoding and decoding device of the encoding method. On the one hand, the present invention can use naked eyes to identify products, certificates or bills through the barcode, and on the other hand, the two-dimensional code reading device of the present invention can be used to read the information hidden in the two-dimensional code, ensuring the integrity of the two-dimensional code Safety, security and confidentiality, and enable the two-dimensional code to carry hidden information, strengthen the anti-counterfeiting and uniqueness of the two-dimensional code, and open up a new application field of the two-dimensional code as a data label.

Description

technical field [0001] The present invention relates to an encoding and decoding method and an encoding and decoding device, in particular to a barcode and two-dimensional code mixed encoding and decoding method and device. Background technique [0002] Due to the remarkable characteristics of large amount of information and low cost of use, two-dimensional codes have been widely used in various fields. Due to the low cost of QR codes and open encoding / decoding technology, the threshold for making counterfeit QR codes is also very low. Due to the image coding characteristics of the two-dimensional code, the content in the two-dimensional code cannot be directly recognized by the naked eye, and the data in the two-dimensional code must be read by a reading device. [0003] Due to the advantages of easy identification and high reliability, barcodes are widely used in commodity circulation and material management. In standard barcodes, the numbers printed under the barcode ca...
