摘要:
该文提出了一种用于MPEG视频内容认证的数字水印算法。为有效抵抗"加值"攻击,该方案利用宏块中离散余弦变换块中低频系数的加权能量关系产生具有很好"半脆弱"特性的特征码。水印的嵌入基于传统的差分能量水印(DEW)算法,以视频码流中的宏块为单位,通过选择合适的能量阈值进一步保证了水印抗常规处理的鲁棒性。实验表明:与传统的DEW算法相比,该算法的水印容量有大幅度提高且可将恶意攻击的区域定位在宏块级。
Abstract:
This paper presents a digital watermarking algorithm for MPEG video authentication.For resisting "AddValue" attack effectively,the basic scheme uses weighted partial energy relation between groups of discrete cosine transform(DCT) blocks in the same macroblock to produce a semi-fragile feature code.The watermark is embedded into the same macroblock using differential energy watermarking(DEW) for reference,which makes the algorithm robust against the ordinary processing.Compared with the traditional DEW,the watermark capacity is improved remarkably and the attack can be localized at marcoblock level.
