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.

目的探讨连续性血液滤过(continuous hemofiltration)治疗顽固性心力衰竭合并肾功能不全的疗效及安全性。方法选择2001年1月至2006年6月在襄樊市第一人民医院肾内科住院的35例顽固性心力衰竭合并肾功能不全患者,25例进行连续性血液滤过治疗(治疗组),10例因经费原因行血液透析治疗(对照组),比较两组治疗前后临床症状的改善,血肌酐(Scr)、尿素氮(BUN)、左室射血分数(LVEF)、心排血量的改变以及并发症的情况。结果治疗组临床症状均明显改善,治疗后患者 LVEF 及心排血量(CO)均明显增加(P<0.01),血液滤过并发症少;而对照组患者临床症状改善不明显,LVEF 及 CO 无明显增加,透析并发症多。结论连续性血液滤过能清除水及毒素,并保持血流动力学稳定,是一种安全、有效的治疗顽固性心力衰竭合并肾功能不全的方法。
