中文摘要：

与因特网技术和人的计算的开发，计算环境在最后三十年戏剧性地变化了。云计算作为在动态、可伸缩、经常虚拟化的资源作为服务在哪个被提供计算的因特网的一个范例出现。与虚拟化技术，云计算提供多样的服务(例如虚拟计算、虚拟存储，虚拟带宽，等等) 为借助于多租赁的公众模式。尽管用户们正在享受云计算供应的超级计算、集体的存储的能力，云安全作为一个热点问题尚待，它在本质是在数据主人和存储服务供应商之间的信任管理。在这份报纸，我们基于云 watermarking 建议一个数据着色方法认出并且保证相互的名声。试验性的结果证明反向的云生成器的坚韧性能保证用户们嵌入社会名声鉴定。因此，我们的工作提供一个引用解决方案给云安全的批评问题。

英文摘要：

With the development of Internet technology and human computing, the computing environment has changed dramatically over the last three decades. Cloud computing emerges as a paradigm of Internet computing in which dynamical, scalable and often virtuMized resources are provided as services. With virtualization technology, cloud computing offers diverse services （such as virtual computing, virtual storage, virtual bandwidth, etc.） for the public by means of multi-tenancy mode. Although users are enjoying the capabilities of super-computing and mass storage supplied by cloud computing, cloud security still remains as a hot spot problem, which is in essence the trust management between data owners and storage service providers. In this paper, we propose a data coloring method based on cloud watermarking to recognize and ensure mutual reputations. The experimental results show that the robustness of reverse cloud generator can guarantee users＇ embedded social reputation identifications. Hence, our work provides a reference solution to the critical problem of cloud security.
