| Summary: | 碩士 === 國立臺中科技大學 === 資訊工程系碩士班 === 106 === The data sharing method of cloud storage services usually discusses the confidentiality of data stored in the cloud and the correctness of the content. Most of the data items are transmitted and calculated in one single operation for the sharing of data. It is not possible to select multiple different data services at the same time.
This study proposes a cloud-based storage service for group information sharing security technology with low transmission and low computational. This study makes each member of the same group to query the information of one or more items required by them according to their own needs. In order to save the user and the cloud service provider’s transmission and operation time, the user can access multiple information items of different types in the cloud by requesting services once to reduce the waiting time for user’s network transmission.
In this research, we will propose a secure and practical technology for data sharing of group members in cloud reduce many computation and communication loads. Moreover, our research will design a more secure and convenient way of information services which is not only protecting the sharing data from being stolen or modified in cloud services for group members (owners), but also protecting the receiver’s privacy and being greatly used by the public. Even though the cloud service that cannot know the data which is stored in cloud. Through this research, we hope to push forward the relative applications, and could be implemented in wireless communication and cloud computing.
