可加密三维码编码、解码方法

An encoding and decoding method for encrypted 3D code

基于二维码技术,引入不同色彩或灰度作为第3维,实现新的三维码生成及加密。空间上由N层二维码序列片段叠加而成,其中1个二维码序列片段为基本信息层,提供可识别的公开信息,其他若干层二维码序列片段为加密信息隐藏层,存放需要保密的信息。

Based on two-dimension code technology,different colors or gray levels are introduced as the third dimension to realize the generation and encryption of new three-dimension code.In space,it is composed of N layers of two-dimension code sequence segments.One of the two-dimensional code sequence segments is the basic information layer,which provides recognizable public information.Other layers of two-dimension code sequence segments are the encrypted information hiding layer,which stores the confidential information.
