中文摘要：
利用嵌入式小波零树对小波变换系数进行编码生成参考数据，采用喷泉码对参考数据进一步编码，并将编码数据与认证数据嵌入到原始图像中．在接收端，通过提取认证数据确定图像中的篡改位置，再从未被篡改区域提取参考数据，经喷泉码解码后重构被篡改区域的内容．与基于分块离散余弦变换的参考数据生成方法相比，所提出的方法克服了恢复图像中的块效应．该方法可实现动态的数据嵌入与图像恢复，通过参数选择可实现恢复面积与恢复质量的平衡．
英文摘要：
We first utilize EZW to encode the wavelet generate the reference data. By extracting forensic data and reference data which is self-embedded into the image, tampered area is detected and reference data is also reconstructed. Comparing to block-based DCT, we overcome the blocking artifact of the recovered image. Besides this, we propose a method which makes the data embedding and image quality dynamic by adjusting the parameters. A balance between the recovered area and recovered quality is also achievable.
