摘要
论文提出了一种基于图形空间结构的在二维条形码中嵌入数字水印的方法,实验结果表明该方法能做到水印信息的不可见,水印信息的嵌入量能满足实际应用的要求,并且不影响条形码的识读。
In this paper, a new method to embed digital watermark in two-dimension barcode is proposed. The experimental result indicates that： this method can prevent the hidden watermark from being attacked; the total embedded information can satisfy the requirements of practical application; it has no influence on reading out through the twodimension barcode.
