摘要 结合二值水印图像的特点,运用汉明码的监督关系式,提出一种基于汉明码的像素级数字水印认证方法,此方法可用于灰度水印图像的内容认证,在认证检测时仅利用检测图就可以准确确认某像素点是否被篡改,并具有篡改定位与修复能力。 A pixel-level digital watermark authentication methed was proposed,lutegrating the factures of Binary watermark image and the supervisory relationship with Hamning code.The method could be applied as content-level certification on grey level digital image.Though generating a watermark Detection map,the method can confirm whether some pixel point has been tampered from the original watermark,with the positioning and repair capacity.
