摘　　要：在分析多重数字水印技术及可见水印和不可见水印应用的基础上,采用图像融合技术对图像和可见水印进行处理并嵌入可见水印,再运用小波变换技术嵌入不可见水印。通过实际应用分析,两种数字水印技术的结合,可发挥各自的优势,能很好地实现对数字图像的双重保护,让非法人员很难盗用图像的内容,即便在强行擦除水印的情况下,依然可以对图像的版权进行有效的保护。Based on the analysis of multiple digital watermarking technology and application of visible and invisible watermarks,this article provides a combined method of using image fusion technology to process images and embed visible watermarks and using wavelet transform technology to embed invisible watermarks. The application of the method shows that the combination of two kinds of digital watermarking technology gives full play to the advantages to the both and provides dual protection for digital image copyright. This dual protection minimizes the risk of embezzlement of image,even under the condition of watermarks are erased forcibly.
