摘　　要：研究了一种同时将含有机器指纹的数字许可和版权标识嵌入数字内容的版权控制方案,由于运用整形小波交换技术,因此通过对部分小波系数的特殊量化来隐藏数字许可和版权标识,而且其提取都不需要知道原始数字内容。该方案不但可用于数字内容非法复制和版权的监测,还可用于版权控制和扩散跟踪,具有一定的实用价值。文章在讨论版权控制模型和算法的基础上,从数字内容加密封装、机器指纹与用户权限捆绑、许可证和版权信息嵌入以及提取等方面,详细地描述了版权控制协议。This article studies the scheme of copyright control,which embeds Digital Permission including machine fingerprinting and Copyright Identification in Digital content simultaneously.Based on integer wavelet transform,this scheme hides digital permission and copyright identification through the special quantization of partial wavelet coefficient ,which can be extracted without knowing the original content.This scheme not only can be used in the detection of illegal copying and copyright of digital content ,but also can be used in tracing the copyright control and the right of use.Experiments show the effectiveness of the scheme is good.On the foundation of discussion of copyright control model and algorithm,this article has described copyright control agreement in detail,including the encryption and encapsulation of digital content ,the binding of machine fingerprinting with user privilege,as well as the embedment and extraction of permission and copyright information and etc.
