一种基于云存储环境下的数据处理机制

A Data Processing System based on Cloud Storage Environment

随着信息时代的迅速发展,全球的数据正爆发式的增长,如何对这些海量的数据进行有效存储使用并保证其隐私性正成为人们关注的焦点。本文利用云存储服务技术和云计算技术有效的解决了人们所担忧的问题。用户把海量的数据上传到多个云服务器,当用户使用这些数据时,传统的方法是把数据下载到本地,再进行相关处理,或者在云上运用隐式安全机制直接进行处理。本文方案中,我们借助云计算的功能及加密操作,对在云端存储的加密数据进行运算,得到我们想要的结果,再由用户解密。该方案既节省了数据恢复到本地的存储空间和计算代价,又能够保护用户在云端数据的隐私性。在当前的技术环境下,有较广泛的应用前景。

With the rapid development of information age, the global data is explosive growing. How to store and use the massive data effectively and ensure the privacy is becoming the focus of attention. In this paper, the use of cloud storage service technology and cloud computing technology solved the problem that people concern effectively. Users upload the massive data to multiple cloud servers. When users want to use these data, the traditional method isto download data to a local server and to do some related processing, or to use the implicit security mechanism to process in the cloud directly. In our paper, we use encryption operation of cloud computing to do some computation with the encrypted data in the cloud. Then the users can encrypt the result. The scheme not only saves the local storage space and computation cost, but also pro-tects the users’ privacy in the cloud. In the current technological environment, our scheme has a wide applied prospect.
