中文摘要：

安全有效的数字媒体内容保护方案已为当前媒体内容应用中最为迫切的技术需求。文中提出了一种新的DRM模型，该模型是基于融合了高安全性的虹膜识别和人脸识别的双子认证系统，能够稳定而准确的通过对非法用户进行访问控制来完成对数字内容使用的权限管理。首先对两种不同生物特征识别技术和DRM系统作简要的介绍，然后对提出系统作详细介绍。为了保证生物数据的安全性，采用基于PKI的安全协议。分析表明双因子认证通过组合两种不同条件来证明一个人的身份，安全性有了明显提高，提出的模型有较高的可靠性，适用于数字内容的安全分发。

英文摘要：

Secure and efficient content protection schemes have become the most urgent technology in current media content application. A new DRM model based on highly secure iris recognition and face recognition is proposed, which can achieve the rights management of digital content exactly through the illegal user＇s access control. This paper first presents two biometric identification techniques and the DRM system, and then introduces the proposed system in detail. To ensure the security of the biometric data, a protocol based on PKI is proposed. Analysis shows the security of this system is improved remarkably by the Double-Biometric technology of identifying a person＇s identity by combining two different conditions. The proposed model is highly reliable and applicable to the secure distribution of digital content.
