超级分发DRM中的关键问题研究

Research on Key Problem of Superdistribution in DRM

在数字阅读中,运营特征以服务提供商为核心。基于此,研究该特征在超级分发过程中,支持增值服务的多设备兼容性问题,提出一种利用在封装的方式,即使用增值证书提供增值权限描述的方法。该方法应用流式分割重排版技术,处理在线服务的增值权限支撑问题,运用虚拟文件技术完成本地管理的增值权限支撑问题。实验结果证明了该方法的可行性和有效性。

This paper presents a research on key problem of superdistribution,especially for service provider being critical part of business operation in digital reading.It proposes an update package method to solve multi-device compatibility problem for supporting service provider＇s value-added service.A value-added license is designed to describe new permission added by service provider.On online reading service aspect,flow segmentation technology is designed to redesign layout.And virtual file technology is designed to support value-added service in local rights and service management.Experimental results show that the method is feasible and valid.
