云计算的隐私保护和数据安全模型探讨

Research on Modules about Privacy Protected and Data Security in Cloud Computing

安全和可信已成为阻碍云计算被用户广泛接纳的主要因素,为了保护用户的隐私和数据安全,云服务提供商应该建立安全可信的数据中心.提出一个云端加密——服务可信访问控制模型,建议使用新的访问控制技术和数字水印技术在云服务提供商和用户之间建立互信机制,提高云服务商对自身信誉的重视程度,从而保护在云上共享的海量数据资源和用户的个人隐私与数据安全.

Trust and security have prevented users from abroad accepting cloud computing. To presreve user＇s privacy and data resources, the Cloud Service Providers （CSPs） must build safe and dependability data centers. The authors suggest building an access control module with cloud to end encrypted and trusted service. The authors suggest to use new tighten access control and digital watermarking for establishing trust between CSPs and users and can urge the CSPs pay more attention to their reputation. These techniques can safeguard the user＇s privacy and data security as well as mass storage share in the cloud.
