There is a wide consensus among feature film production studios that the Internet era brings a new paradigm for film distribution to cinemas worldwide. The benefits of digital cinema to both producers and cinemas are numerous: significantly lower distribution and maintenance costs, immediate access to film libraries, higher presentation quality, and strong potential for developing new business models. Despite these advantages, the studios are still reluctant to jump into the digital age. An important concern regarding digital and conventional cinema is the danger of widespread piracy. Piracy already costs Hollywood an estimated two billion dollars annually, and digital cinema without proper copyright enforcement could increase this number. In this paper, we present a copyright management system that aims at providing the set of necessary security tools: standard cryptographic primitives and copyright protection mechanisms that enable a reliable and secure feature film delivery system. 相似文献

Digital rights management (DRM) is increasingly becoming a necessity for content management and distribution in highly networked environments such as the Internet. However, very few DRM models have been able to achieve commercial success and acceptance among users. This paper analyzes the problems with current DRM environments and proposes an open layered framework for development of DRM systems, where different technologies can interoperate within the framework. Furthermore, interoperability is studied in terms of the proposed layered framework, and problems posed by the current rights expression languages (RELs) are identified. We conclude that a refactoring of current RELs based on a set of design principles is necessary to achieve a reasonable level of DRM interoperability. We emphasize the need for middleware services for DRM, along with their responsibilities and places of operation within the proposed framework. Finally, a specific prototype architecture is introduced that makes use of existing infrastructures in order to implement a DRM environment consistent with the design principles described in this paper. 相似文献

In this article, we present a solution to digital rights management (DRM) for electronic publishing and document management services provided by a third-party application service provider (ASP). We identify legal requirements that service providers have to guarantee with respect to DRM. We elaborate on related technological requirements and implement specific DRM service components compliant with the Open Digital Rights Language (ODRL) standard. Moreover, we show how digital rights of document content can be specified and subsequently enforced using ODRL. We conclude by discussing legal implications of technological innovation—for example, the conflicts that may arise between digital rights enforcement and privacy protection measures, and how it is possible to resolve them. 相似文献

为提高信息系统中权限分配的适应性和安全性,提出了一种扩展的RBAC权限管理模型,通过采取一种新的类SQL数据限定方法,将权限分配中的功能权限和数据权限进行了有效结合,实现权限分配的通用性和灵活性,并通过三权分离成功解决SQL注入风险及系统管理员权限过高问题.实践证明,该模型具有通用性强、灵活方便、安全性高等优点. 相似文献

一个具有公平匿名性的数字版权管理系统 总被引:2,自引:0,他引:2
目前的数字版权管理(DRM)系统注重的只是安全性的考虑,没有充分考虑到用户的购买隐私,利用电子现金里的公平匿名性技术,可以改造现有的DRM模型,使合法的用户具有公平的购买匿名性,同时也可以揭露非法用户的真实身份。 相似文献

In October 2005, Sysinternals' Mark Russinovich discovered a rootkit on his computer, which he later determined stemmed from a Sony-BMG compact disc. In this article, the authors examine the copy-protection software found on those discs and the implications for digital rights management. 相似文献

A fuzzy entity relationship diagram (ERD) data model for managing information about sets of related data files was converted to an object design. To do this, we developed new methods incorporating object model flattening, entity payload data containerization, and a nonintegrated object model design to allow expression of fuzziness. 相似文献

数字版权保护(DRM)已经成为网络环境下数字内容交易和传播的一种关键保障技术。鉴于我国数字内容市场的需求和目前DRM技术的不足,提出一种在图像中动态提取密钥的方法,使得密钥的选择与更新更加灵活,并建立一个三重加密机制,增强了DRM系统的安全性。同时利用遍历加密的方法将内容许可证与用户的多个终端设备进行绑定,建立起用户域,使用户能在多台设备上共享内容。对方案的安全性进行了证明,给出了运行效率的仿真结果和与目前几个主流DRM方案的比较结果。 相似文献
