Digital watermarking technique based on 2-D Barcode
一种基于二维图形码的数字水印技术

After analyzing the digital watermarking techniques for binary images, the conclusion that a successful information hiding technique must be based on the special structure of the hidden media was made. Aiming at a specific binary images PDF417 2D Barcode, a new information hiding method based on boundary shift was brought up. Being combined with RS-code, this method can be widely used in 2D Barcode digital watermarking techniques.
