Abstract
The present invention relates to a coding and decoding method for quick read code (QR code), particularly comprising an encrypt program in a coding module, able to adopt various possible encryption algorithms so as to ensure message safety; and comprising a decrypt program in a decoding module, adopting the decryption algorithms corresponding to the encryption algorithms, thereby proposing an effective and fast 2D bar code algorithm, able to code to generate 2D bar code and decode the 2D bar code by fast video processing technique and enabling the QR code to be widely applied to various fields.
