中文摘要：

基于一种用于彩色印刷防伪图像博奇编码的傅里叶计算全息数字水印方法,设计了一种抗旋转的全息水印防伪方案。通过模拟印刷—图像采集—旋转校正—提取水印的仿真实验,研究了采集过程中图像旋转一定角度后提取的水印质量问题。实验表明：该防伪方案对图像采集中的旋转攻击具有较好的鲁棒性,能满足彩色印刷的防伪要求,且旋转角度∈（-90°,0°）∪（0°,90°）时,提取的水印质量较好,能保证识别。另外,该防伪方案对图像采集中的裁剪、磨损、缩放、平移和翻转攻击,也有较好的鲁棒性。

英文摘要：

According to Fourier hologram digital watermarking method used in color printing based on Burch＇s coding method,a packaging printing rotating distortion resistant holographic watermarking security program was designed.The quality issue of extracted watermark of rotated image by certain angle in image acquiring process was studied with simulation experiments of printing-image acquiring-rotation correcting and watermark extraction.The results showed that the security program had good robustness against rotating attack in acquiring process and could satisfy the security requirements of color printing image.With the rotating angle of ∈（-90°,0°）∪（0°,90°）,the quality of extracted watermark was better and could satisfy the need of recognition.In addition,the security scheme also had good robustness against some attacks,such as cutting,wear,scaling,translation and flip attack.
